    Case Summary: Pursuant to a plea agreement, defendant pleaded guilty to
    second-degree assault and no contest to first-degree robbery for beating the vic-
    tim and stealing his bicycle. The victim later died from his injuries, and the state
    filed felony murder and first-degree manslaughter charges based on his death.
    Defendant moved pretrial to dismiss the indictment, arguing that the homicide
    charges violated the plea agreement. The plea agreement did not specifically
    address the consequences if the victim were to subsequently die, nor did the
    parties discuss that contingency. As a matter of first impression, the trial court
    concluded that the state’s failure to reserve the right to bring further charges
    against defendant precluded it from later doing so. The state filed a direct appeal
    with the Oregon Supreme Court under ORS 186.060(2). Held: (1) in the absence
    of a plea agreement or statutory rule specifically addressing the issue, a contrac-
    tual default rule applies: When it is reasonably foreseeable to the prosecutor that
    the victim may die, and the state intends to reserve the right to reprosecute a
    defendant in the event of a victim’s death, it must disclose its intention as part of
    the plea deal. The judgment of the circuit court is affirmed
    648	                                            State v. King
    NAKAMOTO, J.
    Defendant pleaded guilty to second-degree assault
    and no contest to first-degree robbery in accordance with an
    oral plea agreement reached with the state. Six months later,
    the victim died because of his injuries from the assault, and
    then the state began another prosecution against defendant:
    for felony murder and manslaughter. As a consequence of the
    plea agreement, the trial court granted defendant’s pretrial
    motion to dismiss the indictment and dismissed the case.
    The state appeals the dismissal order. See ORS 138.060(2)(b)
    (state may appeal order dismissing accusatory instrument;
    if murder is charged, appeal is to this court).
    As this court observed in State v. Heisser, 
    350 Or 12
    , 23, 249 P3d 113 (2011), principles of contract law gener-
    ally inform the determination of whether a plea agreement
    has been performed. However, contract principles that apply
    in a commercial setting do not necessarily suffice for an
    analysis of a plea agreement, because the rights of crimi-
    nal defendants “not ordinarily found in contracts between
    private parties * * * may override contractual principles.” 
    Id.
    This case presents an issue of first impression in Oregon
    that lies at the confluence of the contractual incompleteness
    of a plea agreement and the waiver of constitutional rights
    by criminal defendants: whether the state may reprosecute
    defendant for homicide when the state knew at the time of
    defendant’s plea agreement that the victim could die; when
    the potential for future prosecution was not a subject of plea
    negotiations or of the plea agreement; and when defendant
    relinquished trial-related constitutional rights and entered
    pleas on non-homicide charges with the belief that the plea
    agreement ended all prosecutions arising out of the crimi-
    nal incident.
    In seeking reinstatement of the indictment, the
    state contends that, applying ordinary principles of con-
    tract interpretation, the plea agreement poses no bar to the
    state’s otherwise permissible prosecution of defendant for
    homicide and that defendant assumed the risk of the vic-
    tim’s death. Defendant rejoins that the contract principles
    the state advances cannot be woodenly applied when a crim-
    inal defendant relinquishes state and federal constitutional
    Cite as 
    361 Or 646
     (2017)	649
    rights as part of a negotiated plea. He asserts, among other
    arguments, that, to address the contingency of the victim’s
    death, the trial court correctly recognized and applied a
    default contractual term to the plea agreement to bar his
    reprosecution for homicide.
    As did the trial court, we conclude that a contrac-
    tual default rule fills the gap in the plea agreement and pre-
    vents defendant’s reprosecution. Accordingly, we affirm.
    I. BACKGROUND
    Although the parties disagree regarding the con-
    tract and criminal law principles that should govern the
    analysis, they agree that this court reviews the trial court’s
    ruling for legal error. We agree and add that we will not dis-
    turb the trial court’s factual findings if they are supported
    by the record. E.g., Heisser, 
    350 Or at 25-28
     (examining
    under standard). We state the facts in accordance with that
    standard of review.
    A.  The Assault
    One night in early August 2013, defendant and his
    codefendant, Jimenez, were at a hospital in Lebanon, Oregon.
    Defendant was 17 years old. He and Jimenez, an adult, were
    intoxicated and disruptive. A security guard who followed
    them out of the hospital heard defendant tell Jimenez that
    his bicycle had been stolen and that he wanted to beat some-
    one up. Several hours later, the security guard saw defen-
    dant and Jimenez walking a bicycle near the hospital.
    The next day, the victim was found lying in a park-
    ing lot near the hospital. The victim’s bicycle was gone, but
    defendant’s insurance card was found nearby. The police
    then discovered that defendant was a runaway minor and
    that he and Jimenez had been at the hospital. The police
    saw the victim’s bicycle at Jimenez’s residence, and Jimenez
    and defendant were arrested. Both of them made incrimi-
    nating statements during interviews by the police.
    The victim had multiple head injuries and was in
    a coma in the hospital. In the days after the victim was
    found, hospital personnel informed police that he was stable
    but that there was a possibility that he could die from his
    650	                                             State v. King
    injuries. At the end of August, the victim was transported
    to a specialty hospital in Portland for long-term acute care.
    Although the victim regained consciousness several months
    after his move, his brain injuries were so significant that
    the right side of his body was paralyzed; he was incontinent;
    and he no longer could eat or drink, walk, or communicate
    with people normally. He remained bedridden at the long-
    term care facility until his death.
    B.  Defendant’s Plea Agreement and Codefendant’s Trial
    In August 2013, the state charged defendant and
    Jimenez with second-degree assault, ORS 163.175(1)(a)
    (“intentionally or knowingly caus[ing] serious physical injury”
    to the victim), and first-degree robbery, ORS 164.415(1)(c)
    (robbery enhanced by infliction of serious physical injury to
    the victim). In the fall of 2013 and early 2014, the parties
    engaged in negotiations for a plea agreement. The parties
    first attended a settlement conference with a circuit court
    judge in October 2013. The issue of what would happen if
    the victim died was not discussed. The prosecutor provided
    a formal written plea offer to defendant and Jimenez, dated
    the next day, which also was silent regarding that contin-
    gency. In early January 2014, the parties had a second set-
    tlement conference, but that did not result in an agreement.
    Later in January, after the trial court denied defendant’s
    motion in limine seeking merger of the assault and robbery
    counts, defendant and the state arrived at a plea agreement.
    The parties never discussed the possible death of the victim
    and the potential for homicide charges if the victim were to
    die.
    The parties did not enter into a written agreement,
    although defendant and his attorney signed a petition dated
    January 28, 2014, to enter pleas to the charges. The prose-
    cutor did not see the petition before defense counsel provided
    it to the court at a “final resolution” pretrial conference held
    that day. Among other things, the plea petition contained
    the following items: First, it described the two counts of
    the indictment, the maximum penalty for each crime, and
    the plea that defendant would enter on each count. Second,
    it recited various potential collateral consequences of con-
    victions, such as the inability to own or possess firearms if
    Cite as 
    361 Or 646
     (2017)	651
    defendant was convicted of a felony crime; “the imposition of
    certain costs and fees in addition to any fines imposed”; the
    possible violation or revocation of probation, parole, or post-
    prison supervision he may have been serving; and the possi-
    bility of consecutive sentences. Third, it warned that defen-
    dant was giving up most of his rights to appeal, although it
    stated that defendant was making a conditional plea that
    reserved the right to appeal the denial of his motion in
    limine regarding merger of the counts. Fourth, the petition
    contained defendant’s representation that he understood
    that he was “giving up” five enumerated rights related to a
    trial (his “right to a speedy trial by jury,” his right to be rep-
    resented at trial by an attorney, his “right to confront and
    cross-examine witnesses called to testify” against him, his
    “right to compel witnesses to come to court,” and his “right
    to remain silent”) and his “legal status of being innocent
    until proven guilty beyond a reasonable doubt.” And fifth,
    it recited that “[n]o threats” had been made to defendant to
    induce entry of the plea and “no promises” had been made
    “except as may have been stated in open court.”
    The petition did not touch on the condition of the
    victim or what could happen if the victim were to die. Nor
    were those topics raised at the pretrial conference when
    defendant presented the petition to the court.
    Defendant’s plea and sentencing hearing took place
    in late February 2014. The terms of the oral plea agreement
    between defendant and the state were stated on the record.
    In exchange for his pleas, the state and defendant jointly rec-
    ommended to the court that defendant be sentenced to serve
    120 months in prison: 70 months for the assault count and
    90 months for the robbery count, with 50 of those 90 months
    to be served consecutively to (and 40 months to be served
    concurrently with) the prison term for the assault. The state
    also agreed that defendant could appeal the court’s ruling
    that the convictions should not merge. Defendant pleaded
    guilty to assault in the second degree and no contest to rob-
    bery in the first degree. Neither the court nor counsel raised
    the issue of what would happen if the victim died.
    Before the court sentenced defendant for the assault
    and robbery, the victim’s brother described the victim’s
    652	                                                State v. King
    severely diminished physical and mental condition and said
    that family members questioned whether they had made the
    right decision in directing doctors at the hospital “to fight
    for [the victim’s] life.” The prosecutor also described the vic-
    tim’s condition at the hearing:
    “He was in a coma for quite some time at the hospital[.]
    [H]e was ultimately sent to rehab. He’s still in a rehab cen-
    ter. While he’s probably not in a coma he certainly is * * *
    never going to be functioning in the manner that he ever
    was before. Who knows at this point. I mean it’s just a really
    long term process as to where he’s going to be headed.”
    The court sentenced defendant to serve a total of
    120 months in prison, accepting the parties’ recommenda-
    tion for a partially concurrent sentence because of the nego-
    tiated agreement and defendant’s youth. The court also
    imposed two 36-month periods of post-prison supervision
    and assessed felony fines.
    Unlike defendant, Jimenez rejected the state’s plea
    offer. He proceeded to trial with the same prosecutor several
    months later, in May 2014.
    At the trial, the state presented evidence concern-
    ing the victim’s condition. The neurologist who had evalu-
    ated the victim at the hospital testified about the victim’s
    initial prognosis: the victim could have had a “substantial
    risk of death.” The victim’s attending physician at the long-
    term care facility also testified about the victim’s prognosis.
    She recounted that she had told the victim’s family members
    that, because of his conditions, such as being unable to swal-
    low and move appropriately, the victim was “highly likely” to
    develop other significant medical conditions and that, when
    that happened, they should transition him to hospice care
    and not attempt treatment given his overall poor prognosis.
    Defendant also testified at the Jimenez trial, on
    behalf of the defense. Although the record in this case does
    not include a transcript of defendant’s trial testimony, it
    does include the state’s closing argument. The prosecutor
    urged the jury to reject defendant’s account that he had lied
    during his police interview and his self-incriminating testi-
    mony at trial that, as the prosecutor put it, “it was all me,
    Cite as 
    361 Or 646
     (2017)	653
    [Jimenez] didn’t do anything.” She explained that defendant
    had already accepted a plea deal and could testify without
    consequences: Defendant “has already done his thing, he’s
    not going to get into any more trouble, he knows that. So
    why not protect [Jimenez].” The jury convicted Jimenez, and
    he was sentenced to 160 months in prison for the assault
    and the robbery.
    C.  Homicide Charges and Defendant’s Motion to Dismiss
    In August 2014—six months after defendant’s pleas
    on the assault and robbery charges—the victim died. The
    medical examiner determined that his death was the result
    of complications from his head injuries during the assault.
    The state then pursued homicide charges against
    defendant and Jimenez. In 2015, a grand jury issued sep-
    arate indictments against them. Each was charged with
    murder, ORS 163.115, and manslaughter in the first degree,
    ORS 163.118. Their cases were consolidated, and defendant
    and Jimenez filed motions to dismiss. Defendant’s motion to
    dismiss was based on two grounds: (1) protections against
    former and double jeopardy barred the prosecution and (2)
    the homicide charges violated the plea agreement. Only the
    latter ground is at issue on appeal.
    The trial court held an evidentiary hearing on
    defendant’s motion to dismiss. The prosecutor who had han-
    dled defendant’s plea agreement and the Jimenez trial was
    the state’s primary witness. She testified that, when she ini-
    tiated the prosecution of defendant in early August 2013,
    she had information about the victim’s condition from law
    enforcement. She knew then that the victim “was severely
    injured” and “there was some question at that point” about
    whether he was likely to live because of the severity of his
    injuries. By the time of the indictment later in August, the
    prosecutor had spoken with the victim’s family and knew
    that his injuries were severe and there was “going to be
    quite a bit of aftercare”; however, she did not know that the
    victim would die. At the time of the first settlement confer-
    ence, she was getting information from the victim’s father
    and knew that the victim was still living but with limited
    mobility and limited speech. She explained that what would
    654	                                            State v. King
    happen should the victim die was not discussed during the
    prosecution of either of the codefendants. She also testified
    that, at the time of defendant’s plea and sentencing hearing
    and then later in the Jimenez proceedings, she “didn’t know
    what was going to ultimately happen” to the victim or that
    he was “likely to die within a finite period of time.”
    The victim’s brother also testified for the state
    regarding the victim’s health and medical status at various
    stages in the case. He noted that the victim was conscious
    but not speaking at the time of defendant’s sentencing. The
    family was still hoping to see more improvement in his condi-
    tion then; however, by the time of the Jimenez trial, the vic-
    tim’s condition had come to a plateau. He further explained
    that, in August 2014, his family decided to use hospice care
    for the victim, and the victim died within three or four days.
    Both the state and defendant introduced portions
    of the transcript of the Jimenez trial as exhibits. The state
    also introduced other documents concerning defendant’s and
    Jimenez’s assault and robbery cases, including transcripts
    and documents relating to defendant’s pleas.
    D.  The Trial Court’s Ruling and Order of Dismissal
    The trial court stated findings on the record. The
    court found that the victim was “severely injured and that
    the state knew at the time of the assault and at the time of
    filing * * * charges that he could die—possibly die from his
    injuries.” It also found that, when defendant pleaded guilty
    and no contest to the assault and robbery charges pursuant
    to the plea negotiations, the “plea agreement did not specif-
    ically address whether [defendant] would be subject to fur-
    ther prosecution if [the victim] later died.” There was “no
    discussion during the course of the [Jimenez] trial whether
    [defendant] would be offered immunity or anything else for
    his testimony[.]” Defendant had testified at the Jimenez
    trial “apparently in the reliance that this case was con-
    cluded when he had entered his pleas and that he was not
    subject to further prosecution.” In fact, “the prosecutor at
    that time indicated that [defendant] had satisfied his obli-
    gations to the state and that he was not at risk of further
    prosecution.” The court further found that the victim died
    Cite as 
    361 Or 646
     (2017)	655
    because of injuries he sustained in the 2013 assault and that
    “it was reasonably foreseeable that [the victim] would die as
    a result of the injuries he sustained in that assault.”
    The court also issued its ruling on the motions from
    the bench. Although it concluded that former and double
    jeopardy did not bar the homicide prosecutions of defendant
    and Jimenez, the court granted defendant’s motion based
    on his arguments related to his plea agreement. The court
    determined as a matter of law that, in circumstances like
    these, the better practice was to follow the rule from other
    states that had reviewed plea agreements that were silent
    on what would happen if the victim later died. That rule
    required dismissal because the state had failed to reserve
    its right to bring further charges against defendant should
    the victim die.
    The court subsequently entered a written order dis-
    missing the case that contained similar and additional find-
    ings and legal conclusions. The court found that the “state
    was aware at the time of the charges that [the victim] could
    die as a result of his injuries”; during “plea negotiations,
    the state did not specifically preserve the right to bring
    more serious charges” against defendant; “defendant gave
    up rights that may have resulted in his acquittal with the
    belief that he was terminating this incident”; and defendant
    “was not advised that his testimony could be used against
    him in a future criminal matter.” The court explained that
    defendant’s out-of-state authorities were persuasive and
    that, because the victim’s death had been reasonably fore-
    seeable at the time of the plea negotiations, the state was
    obligated to affirmatively reserve the right to bring future
    charges and to inform defendant that the agreement would
    not preclude future prosecution. The state assigns error to
    the order of dismissal.
    II. ANALYSIS
    On appeal, both parties point to the omission of any
    mention in either the plea negotiations or the plea agreement
    of the state’s possible reprosecution of defendant should the
    victim die. Then, using different sets of legal principles, the
    parties draw contradictory conclusions from that omission.
    656	                                            State v. King
    The state contends that, although it did not reserve
    the right to prosecute defendant for murder and manslaugh-
    ter, such a reservation is not necessary under Oregon law.
    Its view is that it retained the right to prosecute defendant
    absent an express agreement with him to the contrary. In
    large part, the state’s argument depends on its normal dis-
    cretion to prosecute a defendant for homicide long after the
    causal event occurred and the absence of any statute or case
    law banning such prosecution. The state also relies on prin-
    ciples of contract interpretation found in Oregon’s common
    law of contracts. According to the state, the onus was on
    defendant and his legal counsel to recognize the risk of the
    victim’s later death—and the subsequent possibility of a
    homicide prosecution—during the negotiation and crafting
    of the plea agreement and, concomitantly, to address those
    risks in the plea agreement. Thus, in the state’s view, the
    trial court erred by dismissing the indictment.
    Defendant argues that the trial court’s ruling can
    be explained and justified by reference to contract law,
    coupled with due regard for the standards required for a
    criminal defendant’s knowing and voluntary waiver of trial-
    related constitutional rights. In particular, defendant views
    the trial court’s ruling—that the state was precluded from
    reprosecuting defendant unless it disclosed during plea
    negotiations or in the plea agreement itself that it might
    bring homicide charges should the victim die—as embody-
    ing a default rule, as that term is understood in contract
    law. When a court supplies a missing term based upon a
    default rule, the implied contract term is based not upon
    the actual intent of the parties but instead on a legal rule.
    Peter Linzer, 6 Corbin on Contracts § 26.1, 400 (Joseph M.
    Perillo rev ed 2010) (implied term based on a default rule
    “may come directly from the law, regardless of the parties’
    intent”). In this case, defendant urges this court to approve
    a default rule that arises in the face of the parties’ silence
    concerning the state’s reprosecution of a defendant should
    the victim die: the state will bear the risk of the victim’s
    death and cannot reprosecute the defendant for homicide.
    For the reasons explained below, we conclude that,
    in the absence of a statutory rule specifically addressing the
    Cite as 
    361 Or 646
     (2017)	657
    issue, a contractual default rule or “gap-filler” is required
    when (1) the victim’s death is reasonably foreseeable to the
    prosecutor and (2) the plea agreement does not address the
    subject of reprosecution in the event of the victim’s death
    and arose from negotiations that also did not address that
    subject. That default rule, which requires the state to dis-
    close that it may reprosecute the defendant should the vic-
    tim die, is derived both from contract law and from respect
    for the criminal defendant’s bargain and waiver of trial-
    related constitutional rights.
    A.  Contract Omissions
    We begin by identifying the salient principles of con-
    tract law that apply to the plea agreement. That threshold
    issue depends on the nature of the contract problem before
    us, an issue that the parties dispute. We agree with defen-
    dant that this case is best understood as one of contract
    omission.
    The state cites Yogman v. Parrott, 
    325 Or 358
    , 361,
    363-64, 937 P2d 1019 (1997), to explain that a court first
    examines the text of a disputed contract provision, and
    then, if an ambiguity exists, considers extrinsic evidence to
    determine the parties’ intent. The state then observes that
    the plea agreement contained no prosecutorial promise—
    either express or implied—to refrain from bringing homi-
    cide charges if the victim died, and it did not otherwise refer
    to the possibility of the victim’s death. And, in the memorial-
    izing plea petition, defendant confirmed that the prosecutor
    had made no promises (other than any stated in open court)
    to induce the plea. Given those features—particularly the
    omission of any term concerning the possibility of the vic-
    tim’s death—the state reads the plea agreement as plainly
    permitting it to reprosecute defendant for homicide.
    But as defendant points out, the parties are not
    arguing about the meaning of a word or phrase or the oper-
    ation of unclear provisions in the plea agreement. Although
    the state is correct that the plea agreement does not address
    the victim’s death or defendant’s reprosecution, the princi-
    ples of contract interpretation that the state cites would
    neatly apply in the case of a contract term that has a disputed
    meaning. As we have recognized before, Yogman provides
    658	                                             State v. King
    an analytical “framework for contract interpretation.” Peace
    River Seed Co-Op v. Proseeds Marketing, Inc., 
    355 Or 44
    , 65,
    322 P3d 531 (2014). That analytical framework works well
    when the proper understanding of a contractual provision is
    at issue. See Williams v. RJ Reynolds Tobacco Company, 
    351 Or 368
    , 379, 271 P3d 103 (2011) (citing Yogman and explain-
    ing that, to “resolve a dispute over the meaning of a contrac-
    tual provision, this court first considers the text of the dis-
    puted provision in the context of the contract as a whole to
    determine whether the disputed provision is ambiguous”);
    James v. Clackamas County, 
    353 Or 431
    , 442, 299 P3d 526
    (2013) (applying Yogman textual analysis after identifying
    the “interpretive issue” in the case). Professor Farnsworth
    explains that the contract problems in those types of cases
    can be characterized as disputes over expression, because
    of vagueness or ambiguity in the terms the parties used.
    E. Allan Farnsworth, Disputes Over Omission in Contracts,
    68 Colum L Rev 860, 860 (1968).
    In contrast, as defendant argues, the contract prob-
    lem in this case concerns the effect of a contract omission.
    The parties’ oral contract omits any mention of the contin-
    gency at issue, which the trial court found was reasonably
    foreseeable: that the victim would die after the parties
    entered into the plea agreement. Farnsworth describes that
    kind of contract problem as a dispute over omission, that is,
    a dispute over what the parties did not say and “the effect
    of their contract on a situation for which they have failed to
    provide.” 
    Id.
     We agree with that characterization of the con-
    tract issue.
    B.  Contractual Default Rules Generally
    When contracts are incomplete because the parties
    have not bargained concerning a term that is essential to
    determining their rights and obligations, so-called default
    rules are sometimes employed by courts to supply the miss-
    ing term. E. Allan Farnsworth, 2 Farnsworth on Contracts
    § 7.16, 346 (3d ed 2004) (the rules that are the source of
    contract terms deemed to apply as a matter of law are com-
    monly called default rules). In those instances, the parties’
    silence functions as the equivalent of assent to a default rule.
    See Farnsworth, 2 Farnsworth on Contracts § 7.16 at 351-52.

    One commentator describes the “default rule” approach in
    contract omission cases by analogizing to word-processing
    programs that have preset margins that might be changed:
    “A word-processing program that required us to set every
    variable needed to write a page of text would be more trou-
    ble than it was worth. Instead, all word-processing pro-
    grams provide default settings for such variables as mar-
    gins, type fonts, and line spacing and leave it to the user
    to change any of these default settings to better suit his or
    her purposes.”
    Randy E. Barnett, The Sound of Silence: Default Rules and
    Contractual Consent, 78 Va L Rev 821, 824 (1992). Thus, a
    default rule is just that. Parties to a contract may expressly
    agree on terms that are the subject of a default rule and
    that are contrary to it. See Farnsworth, 2 Farnsworth on
    Contracts § 7.16 at 346; Linzer, 6 Corbin on Contracts § 26.3
    at 426.
    As defendant points out, this court has imposed con-
    tractual default rules before—albeit couched as “implied”
    terms—to account for an omission in the contract. In
    Browne & Co. v. John P. Sharkey Co., 
    58 Or 480
    , 482, 
    115 P 156
     (1911), for example, when a contract was silent as to the
    time of performance, this court applied a default rule that
    performance must be completed within reasonable time. In
    Kamin v. Kuhnau, 
    232 Or 139
    , 143-44, 374 P2d 912 (1962),
    the plaintiff inventor paid the defendant to use his machine
    shop to develop his ideas for a new garbage truck packer,
    and the defendant subsequently manufactured a number of
    the developed units for the plaintiff before announcing that
    he would manufacture garbage truck bodies in competition
    with the plaintiff. This court found an implied agreement
    by the defendant not to appropriate the plaintiff’s prod-
    uct ideas, regardless of whether the plaintiff could estab-
    lish that the defendant had expressly agreed on that point,
    “as a legal conclusion recognizing the need for ethical prac-
    tices in the commercial world.” 
    Id. at 152
    . Similarly, in
    Perkins v. Standard Oil Co., 
    235 Or 7
    , 16-18, 383 P2d 107
    (1963), this court imposed an “implied” condition of the con-
    tract that restricted the defendant from soliciting plaintiff’s
    customers.
    660	                                                           State v. King
    Default rules may be based on, among other things,
    common practices and usages regularly observed in trans-
    actions in particular areas and, as defendant notes, “basic
    principles of justice.” See Farnsworth, 1 Farnsworth on
    Contracts § 1.10 at 64. Courts determining what default
    rule to apply, Farnsworth counsels, should not rely on “hypo-
    thetical expectations or fictitious intentions, but [on] basic
    principles of justice that guide a court in extrapolating from
    the situations for which the parties provided to the one for
    which they did not.” Farnsworth, 2 Farnsworth on Contracts
    § 7.16 at 351. In addition, a court may “consider the realities
    of the negotiating and drafting processes and supply a term
    that will put the burden of expression on the party that can
    better cope with it because of bargaining power and draft-
    ing skill.” Id. at 353.
    C.  Assuming the Risk of the Victim’s Death
    With that understanding of the contract problem
    presented, we turn to what Oregon law should provide given
    the contract omission in the plea agreement. In the state’s
    view, because the plea agreement is silent, it may repros-
    ecute defendant. We begin with the state’s two-pronged
    argument that no contractual default rule is appropriate for
    the omission. The state’s argument is based in part on con-
    tract law and in part on Oregon statutes concerning plea
    agreements.
    In its reply brief, the state contends that Smith Tug
    v. Columbia-Pac. Towing, 
    250 Or 612
    , 443 P2d 205 (1968),
    provides the answer under Oregon’s common law of con-
    tracts. Under the holding of Smith Tug, the state argues, if a
    risk is foreseeable, then the absence of any contractual pro-
    vision about the risk “gives rise to the inference that the risk
    was assumed.” Id. at 643. The state observes, and defen-
    dant does not disagree, that the state’s decision to prosecute
    defendant for the victim’s death after the initial prosecution
    for assault and robbery would violate neither statutory nor
    constitutional jeopardy protections,1 and the state contends
    1
    See ORS 131.525(1)(d) (subsequent prosecution not barred for offense not
    consummated when former prosecution began); Commentary to Criminal Law
    Revision Commission Proposed Oregon Criminal Procedure Code, Final Draft
    and Report, § 28, 22 (Nov 1972) (explaining that statute as permitting later pros-
    ecution when harm occurs after prior prosecution for same criminal episode; for
    Cite as 
    361 Or 646
     (2017)	661
    that the otherwise lawful prosecution of defendant should
    not be barred by a contract omission. Although the state does
    not expressly say so, its argument implies that defendant,
    and not the state, assumed the risk of the victim’s death.
    The state’s reliance on Smith Tug is unpersuasive,
    for two reasons. First, as the state acknowledges, the trial
    court determined, and the record reflects, that it was reason-
    ably foreseeable to the state that the victim would die from
    his injuries during the assault. There is no evidence that the
    victim’s death was foreseeable to defendant and his coun-
    sel, and the trial court made no parallel determination as
    to the knowledge that defendant and his counsel possessed
    about the victim. And because of that factual problem, the
    state’s argument faces a second difficulty: because the vic-
    tim’s death was foreseeable to the state, to the extent that
    Smith Tug applies to the circumstances here, that case may
    suggest that the state, not defendant, assumed the risk of
    the victim’s death.2
    In addition to its contract law argument, the state
    also relies on two statutes. Citing ORS 135.405, the state
    argues that silence in a plea agreement about future pros-
    ecution is not a promise by the prosecutor to refrain from
    future prosecution. That statute provides, in part:
    “(1)  In cases [meeting certain criteria], the district
    attorney may engage in plea discussions for the purpose of
    reaching a plea agreement.
    “* * * * *
    example, when a defendant is prosecuted for reckless driving and the victim later
    dies, subsequent negligent homicide prosecution is permitted); see also State v.
    Farley, 
    301 Or 668
    , 672, 725 P2d 359 (1986) (explaining what constitutes prohib-
    ited subsequent prosecution for “same offense” under Article I, section 12).
    2
    Smith Tug concerned whether the high bidder for a five-year lease of sub-
    mersible land in the Columbia River from the state for the purpose of mooring
    logs had submitted an invalid bid by adding a contingency—that the lease would
    terminate if the bidder failed to obtain a permit to erect pilings for the moorage—
    that did not substantially conform to the invitation for bids. 250 Or at 638-40. In
    concluding that the variation was substantial and rejecting the bidder’s argu-
    ment that its contingency was reasonable, this court explained that the contin-
    gency was “so obvious and material” that the absence of the contingency from the
    bid would reflect an assumption of the risk, probably explaining at least in part
    why the other bidder, who had not included the contingency, had refused to bid
    more than $2,900 for the lease term when the high bid was $75,000. 250 Or at
    640-41, 643.
    662	                                                State v. King
    “(3)  The district attorney in reaching a plea agree-
    ment may agree to, but is not limited to, one or more of the
    following, as required by the circumstances of the individ-
    ual case:
    “* * * * *
    “(c)  To seek or not to oppose dismissal of other charges
    or to refrain from bringing potential charges if the defendant
    enters a plea of guilty or no contest to the offense charged.”
    The state characterizes the phrase “refrain from bring-
    ing potential charges” in paragraph (3)(c) as specifically
    contemplating that a prosecutor may promise not to bring
    future charges, but, if not, nothing precludes a later pros-
    ecution based on new facts. The second statute identified
    by the state provides that a defense attorney has a duty to
    aid the client in reaching a decision concerning a potential
    plea agreement, which in the state’s view cuts against the
    argument that a default rule should favor defendants. See
    ORS 135.425(2) (“To aid the defendant in reaching a deci-
    sion, defense counsel, after appropriate investigation, shall
    advise the defendant of the alternatives available and of
    factors considered important by the defense counsel or the
    defendant in reaching a decision.”).
    We conclude that neither statute is dispositive. The
    first, ORS 135.405, is one of the statutes that govern a dis-
    trict attorney’s authority to conduct plea discussions with
    a defendant. Rise v. Board of Parole, 
    304 Or 385
    , 390, 745
    P2d 1210 (1987). As this court explained in Heisser, 
    350 Or at 22
    , under the authority of ORS 135.405(3), as “part of a
    plea agreement, the prosecutor may give concessions to the
    defendant in exchange for a plea of guilty or no contest.” See
    also Commentary to Criminal Law Revision Commission,
    Proposed Criminal Procedure Code, Final Draft and Report
    § 263 at 158 (November 1972) (“Subsection (3) sets forth the
    types of concessions that the district attorney may make in
    reaching a plea agreement. Under paragraph (c) the district
    attorney may agree * * * to refrain from bringing potential
    charges against the defendant or a third person.” (Emphasis
    in original.)).
    We agree with the state that, by providing the dis-
    trict attorney with the authority to make concessions, ORS
    Cite as 
    361 Or 646
     (2017)	663
    135.405(3) plainly does not equate an agreement’s omis-
    sion as to future prosecution with the district attorney’s
    promise to refrain from future prosecution. However, at the
    same time, the provision of authority to the district attor-
    ney to make concessions to secure a plea agreement in ORS
    135.405(3) plainly does not speak to whether a contractual
    default rule may address an omission as to future prosecu-
    tion if the victim later dies.
    The legislative history of ORS 135.405 supports that
    reading. In adopting section 263 of the proposed criminal
    procedure code, which later was codified as ORS 135.405, see
    Oregon Laws 1973, chapter 836, section 170, the Criminal
    Law Revision Commission recognized that “the plea negoti-
    ation process should be formally recognized and controlled.”
    Commentary § 263 at 158. The commission observed that
    the United States Supreme Court had described plea bar-
    gaining as “an essential component of the administration
    of justice,” leading “to prompt and largely final disposition
    of most criminal cases.” Commentary § 263 at 159 (quoting
    Santobello v. New York, 
    404 US 257
    , 260-61, 
    92 S Ct 495
    , 
    30 L Ed 2d 427
     (1971)).
    When drafting section 263, the commission took note
    of recommendations contained in a then-recent law review
    article addressing plea bargaining in Oregon. Commentary
    § 263 at 158. Those recommendations included promoting
    public awareness and openness of plea bargaining; reducing
    “the possibility of errors” and “defendant misunderstand-
    ing”; in cases involving indigent defendants, minimizing
    “the effect of financial pressures tempting the established
    attorney to bargain quickly and the marginal attorney to
    bargain not at all”; and uncovering “errors of an attorney.”
    Id. at 158-59.
    Overall, the legislative history indicates that section
    263 was part of an effort to increase openness and fairness
    in the plea bargaining process that included consideration of
    the interests of indigent defendants in the criminal justice
    system. That effort included other provisions instructing
    trial courts to oversee pleas. See ORS 135.385(1) (address-
    ing trial court’s obligation to determine that the defendant
    understands the nature of the charge); ORS 135.390(1)
    664	                                            State v. King
    (addressing trial court’s obligation to determine that the
    plea is voluntarily and intelligently made); ORS 135.395
    (addressing trial court’s obligation to ensure that there is a
    factual basis for the plea of guilty or no contest). We there-
    fore reject the suggestion that ORS 135.405(3) effectively
    functions as an implied statutory bar to the contractual
    default rule that the trial court applied in this case.
    As for the second statute the state cites, ORS
    135.425(2), the state argues that responsibility for advis-
    ing the defendant of the consequences of a plea agreement
    rests not at all with the prosecutor, but with defense coun-
    sel, as well as the trial court. If both the trial court and
    defense counsel fail to recognize the potential for the vic-
    tim’s death and the possibility that new homicide charges
    could be asserted against the defendant as a consequence of
    the death, then, according to the state, a defendant’s rem-
    edy lies in post-conviction relief. Therefore, the state con-
    cludes, a contractual default rule in favor of defendants is
    inappropriate.
    As a practical matter, if we were to accept the
    state’s position, that ultimately would result in the defen-
    dant bearing the consequences of the victim’s later death
    in cases such as this one, despite the existence of post-
    conviction relief actions, ORS 138.510 to 138.686. Although
    ORS 135.425(2) sets out that defense counsel has a respon-
    sibility to advise a defendant of “alternatives available and
    of factors considered important by the defense counsel or the
    defendant in reaching a decision” as to a plea agreement,
    the state’s understanding of defense counsel’s role based
    on that statute undermines the foundation for defendant’s
    pleas and waiver of his rights in this case when the reality of
    plea negotiations is considered. The state’s position assumes
    that defense counsel has equal access to information about
    the victim’s health and prognosis and possible intentions of
    the prosecutor, yet defense counsel may not stand on the
    same ground as the prosecutor.
    In this case, for example, the record establishes that
    the prosecutor had information about the victim’s serious
    medical condition and possible death; there is no evidence
    that defense counsel had the same information. Given that
    Cite as 
    361 Or 646
     (2017)	665
    record, the state’s argument—that defendant has a remedy
    in post-conviction proceedings for agreeing to enter pleas to
    assault and robbery without knowing that potential reprose-
    cution based on homicide charges was on the horizon—rings
    hollow. It is difficult to see how defense counsel could be held
    responsible for constitutionally inadequate representation of
    his client and the consequences of a failure to advise defen-
    dant of the contingent death of the victim and later prosecu-
    tion when it was the prosecutor who knew that the victim’s
    death was foreseeable.
    We conclude that neither statute upon which the
    state relies negates the possibility that a default contractual
    rule should determine the effect of the plea agreement when
    the parties did not address the later death of the victim, but
    when that contingency was foreseeable to the state. And, as
    noted above, Smith Tug does not assist the state, nor does it
    supply a rule that takes into account the criminal law con-
    text in which the plea agreement arose.
    D.  Default Rule When the Victim’s Death is Reasonably
    Foreseeable to the Prosecutor
    We now turn to defendant’s argument that we
    should affirm the trial court’s judgment because that court
    properly recognized and applied a contractual default rule
    to fill the gap in the plea agreement.3 In defendant’s view,
    the trial court properly applied a contractual default rule
    that accounts for a defendant’s waiver of important trial
    rights and protects a defendant’s constitutional rights in
    entering pleas and agreeing to convictions pursuant to a
    plea agreement.
    3
    Defendant also argues that the trial court’s ruling can be explained by,
    and affirmed based on, an “implied-in-fact” contract term derived from contrac-
    tual principles and the actual expectations of the parties in entering into the
    plea agreement. See Card v. Stirnweis, 
    232 Or 123
    , 133-34, 137, 374 P2d 472
    (1962) (minority shareholder’s option to purchase shares of majority shareholder
    upon his death must be considered in light of the parties’ purpose, which was not
    “put fully into writing,” to provide surviving shareholder ability to “prevent an
    unsatisfactory heir or distributee from sharing with him in the future conduct
    of the business”; thus, option agreement implicitly required survivor to be share-
    holder at time he exercised option). However, the state argues that that argu-
    ment is unpreserved, and we do not reach the “implied-in-fact” theory, because
    we decide the case on defendant’s theory that a default legal rule applies in the
    circumstances.
    666	                                            State v. King
    We agree, in light of the constitutional rights that
    a defendant gives up when entering into a plea agreement
    and the requirement that the defendant waive those rights
    knowingly, the knowledge that the prosecutor possessed
    that made the victim’s death reasonably foreseeable to her,
    the necessity of allocating the risk, and the certainty that
    the default rule promotes. We approve a default rule that
    places the burden on the state—when it is reasonably fore-
    seeable to the prosecutor that the victim may die and the
    state intends to reserve the right to reprosecute a defendant
    for homicide in the event of the victim’s death—to disclose
    its intention to the defendant as part of the plea deal, either
    expressly during negotiations or, preferably, as a term of the
    plea agreement itself.
    Principles of criminal law are important to our con-
    clusion. As we observed at the outset, a criminal defendant’s
    rights—not ordinarily present in a commercial contract
    setting—must inform the analysis and implementation of
    a plea agreement. Heisser, 
    350 Or at 23
    . When, as here, a
    criminal defendant enters pleas of guilty and no contest to
    charges in accordance with a plea agreement and is con-
    victed, his or her pleas implicate state constitutional rights,
    see Article I, sections 11 and 12, of the Oregon Constitution,
    and rights under the Fifth and Sixth Amendments to the
    federal constitution. A criminal defendant entering such
    pleas waives the constitutional rights to a jury trial, to con-
    front accusers, and to assert the privilege against compul-
    sory self-incrimination. Lyons v. Pearce, 
    298 Or 554
    , 559,
    694 P2d 969 (1985); McCarthy v. United States, 
    394 US 459
    ,

    89 S Ct 1166
    , 
    22 L Ed 2d 418
     (1969), superseded by rule
    on other grounds, see, e.g., United States v. Cross, 57 F3d
    588, 591 (7th Cir), cert den, 
    516 US 955
     (1995) (describing
    change to Fed R Crim P 11); see also ORS 135.385(2) (the
    court must inform the defendant that a plea involves waiv-
    ing those rights). And defendants waiving their constitu-
    tional rights must understand the rights being waived and
    must do so free from coercion. Lyons, 
    298 Or at 560
    ; see also
    Dixon v. Gladden, 
    250 Or 580
    , 584, 444 P2d 11 (1968) (a valid
    guilty plea is “entirely voluntarily” and made by a defen-
    dant who is “competent to know the consequences” and is not
    “induced by fear, misapprehension, persuasion, promises,
    Cite as 
    361 Or 646
     (2017)	667
    inadvertence, or ignorance” (quoting Huffman v. Alexander,
    
    197 Or 283
    , 251 P2d 87, 253 P2d 289 (1953))); ORS 135.390(1)
    (a court shall not accept a plea of guilty or no contest unless
    “the plea is voluntary and intelligently made”).
    We agree with defendant that the contractual
    default rule is grounded not only on contract law concerning
    omissions in agreements but also on the requirement that
    he knowingly waive his constitutional rights and on a due
    process right to enforce his plea agreement. See Santobello,
    
    404 US at 262
     (holding that, “when a plea rests in any sig-
    nificant degree on a promise or agreement of the prosecu-
    tor, so that it can be said to be part of the inducement or
    consideration, such a promise must be fulfilled”); Puckett v.
    United States, 
    556 US 129
    , 137, 
    129 S Ct 1423
    , 
    173 L Ed 2d 266
     (2009) (when “a defendant agrees to a plea bargain, the
    Government takes on certain obligations[,]” and if they are
    not met, “the defendant is entitled to seek a remedy”). A valid
    plea agreement “presuppose[s] fairness in securing agree-
    ment between an accused and a prosecutor.” Santobello, 
    404 US at 261
    .
    We also note that courts in other jurisdictions have
    reached the same outcome on similar facts, based in large
    part on the importance of a prosecutor’s plainly stated inten-
    tions regarding future prosecution, to ensure that a defen-
    dant is aware of the actual value of those promises and his
    or her own concessions and waivers of trial-related rights.
    For example, in State v. Dye, 127 Ohio St 3d 357, 358, 
    939 NE2d 1217
    , 1219 (2010), the defendant struck a boy with
    his truck, which he was driving while intoxicated and with
    a suspended driver’s license. The boy was severely injured,
    and Dye was charged with, and pleaded guilty to, aggra-
    vated vehicular assault and driving under the influence. 
    Id.
    The state did not reserve a right to file additional charges
    should the boy die, but the boy later died from complications
    of his injuries. Id. at 358-59, 939 NE2d at 1220. The Ohio
    Supreme Court explained that its own prior case, State v.
    Carpenter, 68 Ohio St 3d 59, 
    623 NE2d 66
     (1993), reh’g den,
    68 Ohio St 3d 1448, 
    626 NE2d 689
    , cert den, 
    513 US 1236
    (1994), and cases from other states, underscore that “effect
    must be given to the intention of the state and the defen-
    dant in their plea bargain, and courts should enforce what
    668	                                                          State v. King
    they perceive to be the terms of the original plea agree-
    ment.” Dye, 127 Ohio St 3d at 362, 939 NE2d at 1222. The
    court concluded that, “without an expressed reservation by
    the state of the right to prosecute for any later homicide
    charge, Dye had a reasonable expectation that his plea of
    guilty would end criminal prosecution based on this inci-
    dent” and that requiring the state to express its reservation
    “places no unreasonable burden on prosecutors and ensures
    that defendants are fully aware of the consequences of their
    guilty pleas.” Id. at 363, 939 NE2d at 1223. See also State v.
    Rivers, 283 Conn 713, 726, 931 A2d 185, 193 (2007) (terms
    of plea agreements should be stated clearly and unambig-
    uously, so that defendant knows what is expected from
    him and what to expect in return); State v. Thomas, 61 NJ
    314, 323, 294 A2d 57, 62 (1972) (“we are convinced that the
    defendant anticipated that by pleading guilty to atrocious
    assault and battery, and then serving whatever sentence
    might be imposed, he was terminating the incident,” that
    “this expectation was entirely reasonable and justified,”
    and that “in pressing the presently pending murder charge,
    the State is doing violence to its agreement, and is seeking
    to deprive the defendant of something for which he legiti-
    mately bargained”). Courts in other jurisdictions have also
    relied, in part, on Santobello to caution that disposition of
    charges by plea bargain must be grounded in essential fair-
    ness, Thomas, 61 NJ at 322-23, 294 A2d at 61-62, and “must
    be attended by safeguards to insure the defendant what is
    reasonably due in the circumstances.” Carpenter, 68 Ohio St
    3d at 61, 623 NE2d at 68.
    To be clear, this is not a case in which defendant
    seeks to undo or rescind the plea agreement based on misap-
    prehension of or lack of voluntary assent to its terms. Rather,
    defendant ultimately seeks to enforce the plea agreement as
    he understood it. Through the plea agreement in this case,
    defendant gave up his trial-related constitutional rights and
    agreed to serve a lengthy, 120-month term in prison. He did
    so, the trial court found, “with the belief that he was ter-
    minating this incident” and any future prosecution.4 When,

    Defendant received two benefits from his negotiated agreement—a firm sen-
    tence and the ability to appeal a merger issue. Both, defendant notes, are “mean-
    ingless if the state is allowed to proceed on manslaughter and felony murder

    at the time of the plea agreement, the victim’s death was
    reasonably foreseeable to the state, then putting the burden
    of expression on the state to disclose the risk of the victim’s
    death and its reservation of the right to reprosecute in that
    event provides a reasonable safeguard for defendants waiv-
    ing constitutional rights and creates certainty concerning
    who bears the risk. In this case, the prosecutor was aware
    of facts concerning the victim’s health through the prose-
    cutor’s relationship with the victim’s family, the police, and
    the victim’s medical providers, who testified for the state.
    In accordance with the trial court’s conclusion, the victim’s
    death was reasonably foreseeable to the prosecutor.
    As the United States Supreme Court has more
    recently stated in regard to plea agreements, “the reality
    [is] that criminal justice today is for the most part a system
    of pleas, not a system of trials.” Lafler v. Cooper, 
    566 US 156
    ,
    170, 
    132 S Ct 1376
    , 1388, 
    183 L Ed 2d 398
     (2012). This court
    has recognized that “plea agreements are crucial to the
    proper functioning of the criminal justice system.” Heisser,
    
    350 Or at 21
    .
    In such a system of pleas, prosecutors have an incen-
    tive to cooperate in ensuring that defendants have access to
    basic information that would satisfy the requirement that
    they intelligently enter a plea agreement and waive their
    rights: the reliability of the plea agreement, because the
    defendant understood it and knowingly and intelligently
    charges.” The detriment to him flowing from the plea agreement increased with
    the homicide charges, he explains, because “his confession to assault has now
    become a virtual confession to manslaughter” and an admission of an element
    of first-degree robbery, which in turn is an element of felony murder, as well.
    Moreover, defendant adds, after the plea negotiations, he further exposed him-
    self by testifying at codefendant’s trial, taking full responsibility for the assault,
    without understanding that his testimony could be used against him in a future
    prosecution. Although it may not always be the case, as defendant argues, that,
    when the prosecutor “does not mention potential additional charges during plea
    negotiations, a defendant may reasonably expect that the state is satisfied with
    the charges currently pending against defendant and will not file additional
    charges after he pleads guilty or no contest,” the plea agreement in this case
    provides a benefit to defendant only if he were not reprosecuted for homicide if
    the victim died. See State v. Lordan, 116 NH 479, 481, 363 A2d 201, 203 (1976)
    (“The submission and acceptance of the defendant’s pleas to the first three indict-
    ments must have contemplated that no further charges would be brought, for the
    defendant by his pleas deprived himself of any meaningful defense to the present
    charges.”).
    670	                                                           State v. King
    accepted it. Among defense counsel, the court, and the pros-
    ecutor in this case, it was the prosecutor who was in the best
    position to foresee and predict that the victim could die, and
    it was the prosecutor who would likely reprosecute defen-
    dant for homicide. The default rule we approve in this case
    encourages the prosecutor to disclose that risk and poten-
    tial reprosecution. The burden of the default rule on the
    state is not onerous, as counsel for the state acknowledged
    at oral argument. Indeed, an example of a plea agreement
    with a reservation of the right to reprosecute for homicide if
    the victim were to die can be found in State v. Kephart, 
    320 Or 433
    , 437, 887 P2d 774 (1994), superseded by statute on
    other grounds as stated in State v. Albrich, 
    157 Or App 64
    ,
    66-67, 969 P2d 1033 (1998).5 Accordingly, we affirm the trial
    court’s dismissal of the case.
    The judgment of the circuit court is affirmed.

    The written plea agreement in that case included the following provision:
    “The State agrees not to file other charges concerning criminal behavior
    concerning [the victims] with the following exception. This agreement does not
    prohibit the State of Oregon from charging the defendant with Aggravated
    Murder, Murder, or any other degree of criminal homicide should [one of the
    victims] die from injuries suffered * * * from conduct of the defendant. This
    agreement does not limit the Court’s right to sentence the defendant to any
    term authorized by statute in the event that charges are filed against the
    defendant for the death of [one of the victims]. This agreement does not limit
    the right to the defendant to raise any appropriate legal challenges to the
    filing of any degree of criminal homicide for the death of [the victim].”
