    JOHANSON, C. J. —            Lonnita Haskins appeals the trial court' s judgment entered in Multicare
    Health System d /b /a Tacoma General Hospital'                     s(   Multicare) favor.    She argues that ( 1) she was
    entitled    to       a   jury   instruction   on   res   ipsa loquitur, ( 2) the trial court erred when it permitted
    Multicare to present evidence of collateral source payments, and ( 3) the trial court improperly
    instructed the jury about the burden of proof during voir dire and erred when it permitted
    Multicare'       s   closing     argument     that the jurors   could choose a   burden     of proof   for themselves.
    No. 44655 -3 -II
    We hold that it was reversible error to fail to give Haskins' s proposed res ipsa loquitur
    instruction and that it was not error to permit Multicare to present evidence of past collateral source
    payments. Accordingly, we vacate the judgment in Multicare' s favor, remand for a new trial, and
    do not reach Haskins' s voir dire and closing argument issues.
    On cross appeal, Multicare argues that the trial court erred when it excluded Multicare' s
    designated ER 615 in -court representative and when it declined to give Multicare' s proposed jury
    instruction regarding the tax consequences of personal injury awards.
    We hold that the trial court abused its discretion when it denied Multicare' s request to
    designate an employee who is also a fact witness in the case as its in -court representative under
    ER 615, but it was not an abuse of discretion to decline to give Multicare' s proposed jury
    instruction on the tax consequences of personal injury awards.
    FACTS
    I. HASKINS' S SURGERY
    In 2007, Haskins was diagnosed with cervical cancer. After radiation treatments, Haskins
    had an Indiana pouch surgery in order to correct incontinence.
    In March 2009, Dr. Bahman Saffari performed the surgery. Indiana pouch surgery involves
    removing      portions   of   the large   and   small   intestines   and   using them to    create   a new "   urinary
    reservoir."     1 Report      of   Proceedings ( RP) ( Jan. 16, 2013)         at   24.   The patient' s kidneys are
    essentially detached from the bladder and reconnected to the new Indiana pouch reservoir,
    bypassing the bladder. Indiana pouch surgery also involves the insertion of two stents to help drain
    urine into bags so that urine output is monitored during recovery and pressure is relieved on the
    2
    No. 44655 -3 -II
    pouch while it heals. Dr. Saffari also inserted a Malecot tube that allows hospital staff to flush the
    pouch.
    Dr. Saffari thought that Haskins' s surgery was successful and that there was an 80 to 90
    percent chance that the new Indiana pouch would function as her bladder for the remainder of her
    life. However,       during her    recovery, Haskins      experienced complications.          At 4: 00 PM on March
    11, Haskins was recovering in the hospital and Nurse Shaleeni Fortner assessed Haskins and
    verified that her stents were secure.
    At 9: 59 PM,   certified nurse assistant     Ashley   Barker   emptied     the   urine   bags.   Barker was
    trained on how to handle lines and drains and knew that the stents attached to the urine bags should
    not   be   pulled.   She denied that    she would ever    hang the   urine   bags   over   the bedside.     She claimed
    she did not notice whether Haskins' s stents had been pulled out because the blankets of her bed
    were covering the tubes. But Haskins' s urine output was good.
    At 11: 00 PM, Haskins noticed that her stents were not putting out any urine. After Nurse
    Fortner and the charge nurse, Nurse Debbie Dick, made a complete assessment, they found that
    there had not been any urine output but that nothing appeared to be out of place and that there were
    not "   any   problems at   the   stent."   4 RP ( Jan. 17, 2013) at 280 -81.
    At 11: 45 PM, Nurse Rebecca Sumey noticed that Haskins' s urine output was still low based
    on when Barker had last emptied the bags at 9: 59 PM. Nurse Sumey was the first person to notice
    that Haskins' s stents had become dislodged and testified that they had been pulled out about 14
    inches. Nurse Surrey' s entry in the records that night stated that the stents had been pulled out 50
    to 60 centimeters. Haskins told Nurse Sumey that she thought the stents became dislodged when
    Barker hung the urine bags over the side of the bed.
    3
    No. 44655 -3 -II
    The next morning, Dr. Saffari discussed Haskins' s stents and urine output with her and she
    had                         bags          the             the bed.   However, at
    told him that   she   thought Barker             hung    the   urine          over         side of
    trial, Haskins did not remember anything that happened on March 11 and did not remember seeing
    the bags   hanging     over   the   side   of    her bed.      Because the stents became dislodged, Haskins
    experienced acute renal       failure.     Although she made a complete recovery, because of the stent
    complications, Haskins required an additional procedure and additional recovery time to correct
    the problem with her stents and to avoid permanent kidney damage.
    II. THE TRIAL
    In a motion in limine, Haskins argued that evidence of collateral source payments should
    not be admitted because RCW 7. 70. 080 is unconstitutional. The trial court admitted evidence of
    past compensation but excluded evidence of future collateral source payments.
    Multicare designated Barker             as   its in -court   representative pursuant         to ER 615.    Haskins
    moved    in limine to   exclude     Barker because        she was a " critical witness."         1 RP ( Jan. 14, 2013) at
    3.   The court agreed and granted Haskins' s motion because Barker was a factual witness.
    Haskins offered expert testimony from two witnesses, Dr. Oliver Dorigo, the chief
    gynecologic oncologist at        Stanford       University,     and    Karen Huisinga,        a nurse practitioner.    Both
    testified that the most likely explanation for her stents becoming dislodged 10 to 14 inches was
    hospital negligence. Nurse Huisinga also testified that hanging urine bags over the side of the bed
    falls below the standard of care for nurses and that, in her opinion, Haskins' s injury probably
    happened when Barker hung the bags over the bedside.
    4
    No. 44655 -3 -II
    Haskins also called Dr. Saffari, Nurses Fortner, Barker, Surrey, and Katherine Bechtold'
    as   fact   witnesses     and   to   establish    the    appropriate      standards    of care   in nursing.      Haskins also
    testified.
    Multicare    also    offered      testimony from          two   experts:     Cheyenne Haines, a nurse with
    experience caring for recovering surgery patients, and Dr. Karny Jacoby, a urologist who testified
    that she prefers not to perform Indiana pouch surgeries. Dr. Jacoby also provided an expert opinion
    that "[    t] ubes fall out all the time" and that it often happens when patients roll around in bed or if
    patients are confused and pull them out themselves. 2 RP ( Jan. 24, 2013) at 25.
    Multicare proposed a jury instruction stating that personal injury awards are not taxable.
    The instruction         stated, "    Any award to plaintiff will not be subject to federal income tax, and
    therefore     you should not add or subtract             for   such   taxes in   fixing the   amount of   any   award."   Clerk' s
    Papers ( CP)      at   163. The trial court refused to give the instruction because " it would conflict with
    the   no    insurance instruction." 5 RP ( Jan. 29, 2013) at 184.
    Haskins proposed the               standard       6   Washington Practice:           Washington Pattern Jury
    Instructions: Civil 22. 01,           at   255 ( 6th   ed.   2012) ( WPI) instruction on res ipsa loquitur. She claimed
    that she was entitled to the instruction based on expert testimony and recent case law. Multicare
    argued that Haskins did not show that " she wasn' t the sole cause" of her injury and that res ipsa
    loquitur      should   only be      applied "   sparingly."       5 RP ( Jan. 29, 2013) at 147. The trial court declined
    to give Haskins' s proposed instruction.
    1 Nurse Bechtold was Multicare' s chief nursing officer.
    5
    No. 44655 -3 - II
    The jury found in Multicare' s favor and the trial court entered judgment accordingly.
    Haskins appeals from that judgment.
    ANALYSIS
    I. THE PROPOSED RES IPSA LOQUITUR JURY INSTRUCTION
    Haskins argues that the trial court erred when it failed to instruct the jury on res ipsa
    loquitur. We agree and, accordingly, vacate the judgment and remand for a new trial.
    A. STANDARD OF REVIEW AND RELEVANT LAW
    Whether a plaintiff is entitled to a res ipsa loquitur instruction is a question of law that we
    review   de   novo.   Pacheco     v.   Ames, 
    149 Wn.2d 431
    , 436, 
    69 P. 3d 324
     ( 2003).                         Res ipsa loquitur
    establishes    only   a permissive      inference       of negligence.        Curtis v. Lein, 
    169 Wn.2d 884
    , 889, 
    239 P. 3d 1078
     ( 2010) ( quoting          Zukowsky     v.   Brown, 
    79 Wn.2d 586
    , 600, 
    488 P. 2d 269
     ( 1971)).                   Res
    ipsa loquitur is    applied   only sparingly "'         in peculiar and exceptional cases, and only where the facts
    and   the demands      of   justice   make   its   application essential. "'              Tinder   v.   Nordstrom, Inc., 
    84 Wn. 787
    , 792, 
    929 P. 2d 1209
     ( 1997) ( quoting Morner                           v.   Union Pac. R. R. Co., 
    31 Wn.2d 282
    ,
    App.
    293, 
    196 P. 2d 744
     ( 1948)).
    Res ipsa loquitur applies where the plaintiff can demonstrate
    1) the accident or occurrence that caused the plaintiff' s injury would not ordinarily
    happen in the    absence of negligence, ( 2) the instrumentality or agency that caused
    the plaintiff' s injury was in the exclusive control of the defendant, and ( 3) the
    plaintiff did not contribute to the accident or occurrence.
    Curtis, 
    169 Wn.2d at 891
     ( citing Pacheco, 
    149 Wn.2d at 436
    ). A plaintiff is entitled to a res ipsa
    loquitur instruction if      each element         is   supported       by   substantial evidence.          WPI 22. 01, author' s
    cmts. at   256 ( citing Pacheco, 
    149 Wn. 2d at 444
    ).    Substantial evidence is evidence that is " of a
    6
    No. 44655 -3 -II
    sufficient quantum to persuade a fair -minded person of the truth of a declared premise."
    Nationscapital     Mortg. Corp.         v.   Dep' t of Fin.   Insts.,   
    133 Wn. App. 723
    , 738, 
    137 P.3d 78
     ( 2006).
    B. THE ELEMENTS OF RES IPSA LOQUITUR
    1.        FIRST ELEMENT - THE INJURY IS NOT THE KIND THAT ORDINARILY HAPPENS IN
    THE ABSENCE OF NEGLIGENCE
    The primary dispute here is whether Haskins offered substantial evidence that her injury is
    of   the kind that does        not   ordinarily   occur   in the   absence of negligence.      Haskins argues that Dr.
    Dorigo' s expert testimony was sufficient to persuade a fair -minded person that stents do not
    body      in the                            We agree and
    ordinarily slip 14 inches            outside a patient' s                        absence of negligence.
    conclude that Haskins provided substantial evidence that her injury is not of the type that ordinarily
    happens in the absence of negligence.
    A plaintiff may prove that the accident producing the injury does not normally happen in
    the absence of negligence in one of three ways:
    1) When the act causing the injury is so palpably negligent that it may be
    inferred   as a. matter of law, i.e., leaving foreign objects, sponges, scissors, etc., in
    the   body,   or amputation of a         wrong   member; (       2) when the general experience and
    observation of mankind teaches that the result would not be expected without
    negligence; and ( 3) when proofby experts in an esoteric field creates an inference
    that negligence caused the injuries."
    Curtis, 
    169 Wn.2d at 891
     ( emphasis     added) ( internal quotation marks omitted) (       quoting Zukowsky,
    
    79 Wn.2d at 595
    ).
    At trial, Haskins relied on the third prong: that her expert in an esoteric field, Dr. Dorigo,
    created an     inference that       negligence caused        the injuries.      Dr. Dorigo is a gynecologic oncologist
    7
    No. 44655 -3 -II
    2
    and   has    performed       dozens      of   urinary diversion               surgeries.       Dr. Dorigo' s testimony provided
    substantial       evidence     that   negligence         was   the    cause       of   her injuries.   He testified that he had
    performed        20 Indiana     pouch surgeries and             20    additional       urinary diversion     surgeries.   Haskins' s
    attorney     asked, "   Have you personally every [ sic] had a ureteral stent pulled out of the body 10 to
    14 inches        following   one of    those       operations ?"     RP ( Jan. 22, 2013) at 8. Dr. Dorigo answered that
    he had neither had that happen to one of his patients nor had he ever heard of such a problem
    occurring in his time at University of California Los Angeles. RP ( Jan. 22, 2013) at 8. Dr. Dorigo
    testified that, in his opinion, negligence was the most likely cause of Haskins' s injury in this case.
    We conclude that the trial testimony satisfies the first of the three elements needed to
    support Haskins' s res ispa loquitur instruction. Dr. Dorigo' s testimony identifying the hospital' s
    negligence as the most likely explanation for Haskins' s injury is enough to persuade a fair -minded
    individual that her injury is not the type that ordinarily happens in the absence of negligence.
    Brown v. Dahl, 
    41 Wn. App. 565
    , 581 n. 12, 
    705 P. 2d 781
     ( 1985).
    2.       MULTICARE' S NONNEGLIGENT EXPLANATION MUST COMPLETELY EXPLAIN
    HASKINS' S INJURY
    Multicare argues that several witnesses, including Dr. Dorigo, Dr. Saffari, and Dr. Jacoby,
    testified that      ureteral    stents             out   frequently       and    inadvertently     without negligence.      Haskins
    slip
    argues that her burden is only to provide substantial evidence that this type of injury ordinarily
    does   not       happen in the        absence       of negligence, even             if Multicare     can   present   possible, " non -
    negligent        explanations."       Br.   of   Appellant     at   23.       We agree with Haskins.
    2 Neither party contests that urinary diversion surgery is the esoteric field in which his expert
    opinion is relevant.
    8
    No. 44655 -3 -II
    Haskins is entitled to a jury instruction on res ipsa loquitur unless there is other evidence
    that completely        explains     her   injury.    Pacheco, 
    149 Wn.2d at 440
    .    In Pacheco, an oral surgeon
    who performed a wisdom tooth extraction procedure drilled in the wrong place in his patient' s
    mouth. 
    149 Wn.2d at 434
    . Dr. Ames informed him that because the x -ray was misprinted with an
    LR," he had drilled in the wrong                  place.    Pacheco, 
    149 Wn.2d at
      434 -35.        The Pacheco court
    directly addressed whether res ipsa loquitur is appropriate where evidence exists that the injury
    could   have happened          without    the defendant'      s negligence.        See 
    149 Wn.2d at
      438 -39. The court
    held that res ipsa loquitur is only defeated by an alternative explanation where " an inference [ of
    negligence] is not possible, and thus there is nothing upon which the doctrine can operate."
    Pacheco, 
    149 Wn.2d at 440
     ( citing    Covey    v.   W. Tank Lines, Inc., 
    36 Wn.2d 381
    , 391, 
    218 P. 2d 322
     ( 1950)).       The plaintiff is entitled to the instruction as long as she presents substantial evidence
    to satisfy    each element and other evidence                does   not "   completely     explain[ ]"      the injury. Pacheco,
    
    149 Wn.2d at 440
    .
    Here, Dr.       Saffari testified that the stents can become dislodged in the absence of
    negligence, either inadvertently or as the result of a patient' s natural movements in bed. Dr. Dorigo
    also   testified that stents are slippery objects and can "[                  t]heoretically" become dislodged even in
    the absence of negligence. RP ( Jan. 22, 201.3) at 40. Multicare' s expert, Dr. Jacoby, testified that
    t] ubes    fall   out all   the time"   even     in the   absence of      any   negligence.      2 RP ( Jan. 24, 2013) at 25.
    Multicare certainly           presented alternate explanations           for Haskins'      s    injury:   inadvertent slippage or
    the    patient' s natural movements.                But Pacheco does not require Haskins to rule out all other
    explanations.        See 
    149 Wn.2d at 440
    .   She is entitled to the instruction where she has presented
    substantial evidence of each element of res ipsa loquitur, unless an alternate explanation
    9
    No. 44655 -3 - I1
    completely explains her injury. WPI 22. 01, author' s cmts. at 256 ( citing Pacheco, 
    149 Wn.2d at 444
    ).
    Like in Pacheco, Haskins' s injury could be based either on Multicare' s negligence or other
    nonnegligence explanations. Because Haskins presented substantial evidence of the first element
    of res ipsa loquitur, the burden is shifted to Multicare to completely explain her injury in order to
    defeat her      claim   to   an   instruction.        Pacheco, 
    149 Wn.2d at 440
    .   However its evidence only
    suggests another explanation and does not rule out its own negligence. Multicare is free to present
    alternate explanations; each will be presented to the jury and it is up to the jury to decide the issue.
    See Pacheco, 
    149 Wn.2d at
      440 -41.   Based on Dr. Dorigo' s testimony alone, as an expert in an
    esoteric   field—urinary diversion             surgeries—   Haskins presented substantial evidence that her injury
    is not the type that happens in the absence of negligence and Multicare has not provided sufficient
    evidence to completely explain her injury. Curtis, 
    169 Wn.2d at 891
    .
    Therefore, we conclude that Haskins satisfied the first of the three elements and the trial
    court erred when it found that she had not.
    3.       SECOND ELEMENT - THE INJURIES WERE CAUSED BY AN AGENCY OR
    INSTRUMENTALITY WITHIN THE EXCLUSIVE CONTROL OF THE DEFENDANT
    The parties did not argue at trial nor do they argue on appeal that the second element of res
    ipsa loquitur    was at     issue.    Thus, we decline to review the second element and hold that Haskins
    provided substantial evidence that Multicare was in exclusive control of the instrumentality that
    caused her injury.
    10
    No. 44655 -3 -II
    4.          THIRD ELEMENT - THE INJURY -CAUSING ACCIDENT IS NOT DUE TO ANY
    VOLUNTARY ACTION OR CONTRIBUTION ON THE PART OF THE PLAINTIFF
    Haskins argues that Dr. Dorigo and Nurse Huisinga provided substantial evidence that
    Haskins' s own acts did not cause or contribute to her own injury and that Multicare' s suggestion
    otherwise       is   speculation and,      ultimately,   a question of     fact for the      jury. We agree with Haskins
    that she presented substantial evidence that she did not voluntarily cause or contribute to her injury.
    Where Haskins presents substantial evidence that she did not contribute to her injury, she
    is entitled to a res ipsa loquitur jury instruction. WPI 22. 01, author' s cmts. at 256 ( citing Pacheco,
    
    149 Wn.2d at 444
    ). Substantial evidence exists where the plaintiff has provided enough evidence
    to   persuade a        fair -minded     person of   the truth of   her   assertion.     Nationscapital   Mortg. Corp.,   133

    in   a   jury   instruction because '           the advent of comparative fault should logically eliminate the
    element of           the   absence of    the   plaintiff' s contribution    to the    accident ...    unless the plaintiff' s
    negligence appears             to be the sole     proximate cause of       the   event. "'    WPI 22. 01, author' s cmts. at

    Haskins' s theory of her injury is that Barker, when she drained her urine bags just before
    10: 00 PM,                  the bags          the bedside,   which caused        her   stents   to become dislodged.    Dr.
    hung                   over
    Dorigo' s testimony alone indicates that this and not any of Haskins' s movements or voluntary
    actions was the most likely cause of Haskins' s injury. He testified that in his opinion and based
    on his experience and his review of Haskins' s medical records, her stents became dislodged when
    Barker hung Haskins' s urine bags over the side of the bed and that they would not have slipped 10
    to 14 inches outside her body if Haskins had voluntarily caused the slippage herself. Haskins' s
    11
    No. 44655 -3 -II
    medical records reflect that Haskins also told Dr. Saffari that the stents were accidentally dislodged
    by hanging the draining bags over the bed.
    Nurse Huisinga also opined that because of the manner in which Haskins' s stents became
    dislodged, Haskins had not caused the dislodgement herself either voluntarily or inadvertently. In
    her opinion, if Haskins had experienced a " psychotic moment" or became confused, she would
    have   pulled   the Malecot tube out        first   and not      the   stents.    RP ( Jan. 22, 2013)      at   80.   She thought
    that   Haskins   was not   the "   mechanism        for this      the    stents   being   removed --    at all."      RP ( Jan. 22,
    2013) at 80. Nurse Huisinga' s testimony, coupled with the testimony of Dr. Dorigo, is sufficient
    to persuade a fair -minded person that Haskins did not voluntarily cause or contribute to her injury.
    Multicare' s argument that Haskins could have contributed to her injury misses the point
    and ignores the standard of review. Haskins' s burden is only to provide substantial evidence that
    she did not voluntarily contribute to the " accident or occurrence" that caused her injury; she need
    not    completely   exclude   her   own contribution as a potential cause.                    Pacheco, 
    149 Wn.2d at 444
    .
    Dr. Dorigo and Dr. Saffari agreed that stents on occasion can slip from the patient' s natural
    movements.       But Haskins is not required to eliminate all doubt as to whether she could have
    contributed to the injury in order to get an instruction. Pacheco, 
    149 Wn.2d at 444
    . She need only
    present substantial evidence         that   she     did   not contribute        to the   injury- causing   accident.         The trial
    court,   therefore,   should not weigh        Haskins'       s   theory    of    the   case against   Multicare'      s.     Once she
    meets the substantial evidence threshold, Haskins is entitled to a res ipsa loquitur instruction unless
    Multicare    can prove     that Haskins' s     was '       the   sole proximate cause of          the event. "'            WPI 22. 01,

    No. 44655 -3 - II
    Here, apart from testimony that Haskins' s contribution could have theoretically caused the
    stents to become dislodged in this way, Multicare presented no evidence that was what happened
    here.                                              that Haskins' s     own    voluntary   actions   were   the "   sole
    Accordingly,   we   cannot   conclude
    proximate cause" of her injuries. Haskins met her burden when she supported her theory (that the
    stents became dislodged as a result of Barker' s negligence) with enough evidence to persuade a
    fair -minded person of its truth.
    Accordingly, we hold that Haskins provided substantial evidence that she did not
    voluntarily cause or contribute to her injury and, instead, that Barker' s negligence caused her
    injury.
    C. CONCLUSION
    Because Haskins provided substantial evidence to support all required res ipsa loquitur
    elements, we     hold that it   was error    to fail to   give   Haskins'   s proposed res   ipsa instruction.      We
    vacate the judgment in Multicare' s favor and remand for a new trial.
    II. THE COLLATERAL SOURCE DOCTRINE IN MEDICAL MALPRACTICE CASES AND THE
    CONSTITUTIONALITY OF RCW 7. 70. 080
    Haskins argues that RCW 7. 70. 080, permitting parties to present evidence of past collateral
    source payments in medical malpractice cases, is unconstitutional because it violates separation of
    powers principles and, therefore, the trial court erred when it permitted Multicare to offer evidence
    3
    of past collateral source payments.         Specifically, Haskins argues that the common law collateral
    3 Multicare argues, as a threshold issue, that Haskins failed to preserve the constitutionality
    question.  We conclude that Haskins did preserve the issue because Haskins' s motion in limine
    explicitly requested that the trial court either exclude evidence of collateral source payments
    because RCW 7. 70. 080 is unconstitutional, or, in the alternative, limit the collateral source
    evidence that Multicare could present to past compensation based on the language of the statute.
    13
    No. 44655 -3 -II
    source doctrine is a procedural court rule and where a statute conflicts with a procedural court rule,
    separation of powers principles are         implicated     and   the   statute   is   unconstitutional.   We disagree.
    Because the common law collateral source doctrine is not a court rule and Haskins does not identify
    a formal court rule that conflicts with RCW 7. 70. 080, there is no violation of separation of powers
    principles. Accordingly, RCW 7. 70.080 is constitutional with respect to the admission of evidence
    of past collateral source payments and the trial court did not err when it permitted Multicare to
    present such evidence.
    RCW 7. 70. 080 IS CONSTITUTIONAL
    There are some fundamental functions which are inherent in the power of the judicial
    branch; among them is the          power    to    promulgate rules       for   practice    in the   courts.   Putman v.
    Wenatchee    Valley Med. Ctr., PS, 
    166 Wn.2d 974
    , 980,             
    216 P. 3d 374
     ( 2009). But where it is alleged
    that ( 1) a statute conflicts with a court rule, we ( 2) attempt to harmonize them and give effect to
    both but,   where   this is impossible, ( 3)     the court rule prevails in procedural matters and the statute
    prevails in substantive matters. Putman, 
    166 Wn.2d at 980
    .
    The procedure for adopting and amending court rules is explained in GR 9, entitled
    Supreme Court     Rulemaking." This process involves a request to amend, adopt, or repeal a rule;
    the Supreme Court' s initial consideration of the proposed rule; consideration by the Washington
    State Bar Association and the lower courts; the opportunity for notice and public comment; and
    final   adoption   by   the Supreme Court.                      h).
    GR 9( d), ( f) -(
    Haskins' s argument here fails at the first step in a separation of powers analysis because
    the   collateral source    doctrine is   not a   formal   court rule.   It was not adopted through the Supreme
    Court rulemaking process but is, rather, a common law doctrine. Adcox v. Children' s Orthopedic
    14
    No. 44655 -3 -II
    Hosp. &    Med. Ctr., 
    123 Wn.2d 15
    , 40, 
    864 P. 2d 921
     ( 1993) ( " RCW 7. 70. 080 replaces the common
    law 's   collateral source rule ") (emphasis added).       Haskins, therefore, points to no conflict between
    the statute and a court rule, but instead argues that the common law collateral source doctrine
    should be treated as if it were a formal court rule for the purpose of a separation of powers analysis.
    She points to no authority to support this argument, however, and we are aware of none. Without
    a formal court rule, there is no conflict between that rule and a statute and, thus, no violation of
    the separation of powers.
    First, to support her argument, Haskins asks us to apply the holding from Diaz v. State, 
    175 Wn.2d 457
    , 
    285 P. 3d 873
     ( 2012), to this          case.   But Diaz is distinguishable. In Diaz, the plaintiff
    was misdiagnosed with cancer.         
    175 Wn.2d at 460
    . Diaz settled with some of the defendants and
    sought to exclude evidence of these settlements at trial, but the court admitted the evidence under
    RCW 7. 70. 080. Diaz, 
    175 Wn.2d at 461
    .   Our Supreme Court held that RCW 7. 70.080 violates
    separation of powers principles and is thus unconstitutional to the extent that it conflicts with ER
    408, prohibiting the admission of settlement evidence generally, because ER 408 and RCW
    7. 70. 080 cannot be harmonized and ER 408 is a procedural, not substantive, court rule. Diaz, 
    175 Wn.2d at 471
    .
    Here, Haskins   asks us   to   resolve a    different kind   of conflict.   The conflict in this case is
    between the collateral source doctrine and RCW 7. 70. 080. Unlike ER 408, however, the collateral
    source doctrine is not a formal court rule, and Haskins does not argue that RCW 7. 70. 80 conflicts
    with anyy other formal court rule. We conclude, therefore, that Diaz does not apply.
    Second, the separation of powers analysis that Haskins asks us to apply to resolve the
    conflict between RCW 7. 70. 080 and the collateral source doctrine has been applied only to defeat
    15
    No. 44655 -3 -II
    statutes that conflict with formal court rules. See, e. g., Diaz, 
    175 Wn.2d at
    470 -71 ( RCW 7. 70. 080
    is unconstitutional where it conflicts with ER 408, prohibiting the admission of evidence of
    settlements);     Putman,      
    166 Wn.2d at
      982 -85 (   RCW 7. 70. 150 is unconstitutional because its
    requirement that plaintiffs file a certificate of merit with medical malpractice claims conflicts with
    pleading   requirements        in CR 8     and   CR 11);    Waples v. Yi, 
    169 Wn.2d 152
    , 158 -61, 
    234 P. 3d 187
    2010) ( RCW 7. 70. 100( 1)          conflicts with CR 3( a) and is unconstitutional because it requires an
    additional   step to   commence a civil action             in   medical malpractice cases);        State v . Gresham, 
    173 Wn.2d 405
    , 428 -32, 
    269 P. 3d 207
     ( 2012) ( RCW 10. 58. 090 conflicts with ER 404( b) because it
    permits    the   admission of prior misconduct              for   character evidence purposes).          Haskins tries to
    equate the common law collateral source doctrine with a formal court rule in order to set up a
    separation of powers violation. Our precedent does not support this view and her claim fails.
    Finally,    in Adcox,      our   Supreme Court          recognized          that RCW 7. 70. 080 "   replaces"   the
    common law collateral source doctrine. 
    123 Wn.2d at 40
    . In Adcox, the hospital sought to present
    evidence of collateral source payments to the jury and the trial court found that it, instead, would
    make any necessary collateral source offsets posttrial. 
    123 Wn.2d at 40
    . Our Supreme Court held
    that, under the language of the statute, the hospital was entitled to present collateral source
    evidence     to the   finder   of   fact. Adcox, 
    123 Wn.2d at
      40 -41.   Although the court was not asked to
    pass on the constitutionality of the statute, it stated that RCW 7. 70. 080 replaces the collateral
    source doctrine, acknowledging that RCW 7.70. 080 was a proper exercise of legislative power.
    Adcox, 
    123 Wn.2d at
    40 -41.
    Because the common law collateral source doctrine is not a court rule and Haskins does
    not identify a formal court rule that conflicts with RCW 7. 70. 080, there is no violation of
    16
    No. 44655 -3 -II
    separation of powers principles. Accordingly, RCW 7. 70. 080 is constitutional with respect to the
    admission of evidence of past collateral source payments and the trial court did not err when it
    permitted Multicare to present such evidence.
    III. MULTICARE' S CROSS APPEAL
    Because the trial court failed to give the res ipsa loquitur instruction, we remand for a new
    trial and, thus, we reach the merits of Multicare' s cross appeal. Multicare argues that the trial court
    improperly excluded its designated ER 615 in -court representative from the courtroom, and that
    the trial court abused its discretion when it failed to instruct the jury regarding the tax consequences
    of personal          injury   awards.        We agree that the trial court improperly excluded Multicare' s
    designated ER 615 representative, but conclude that the court did not abuse its discretion when it
    failed to give the proposed instruction on the tax consequences of personal injury awards.
    A. THE EXCLUSION OF MULTICARE' S DESIGNATED ER 615 REPRESENTATIVE
    Multicare first argues that the trial court improperly excluded its representative, Barker,
    from the          courtroom   in   violation of    ER 615. We agree.
    We     review    interpretation       of   evidentiary   rules   de   novo.   Diaz, 
    175 Wn.2d at 462
     ( citing
    State   v.   Foxhoven, 
    161 Wn.2d 168
    , 174, 
    163 P. 3d 786
     ( 2007)).                         Once we determine that the rule
    was interpreted correctly, we review a trial court' s decision for an abuse of discretion. Diaz, 
    175 Wn.2d at 462
     ( citing State   v.   Neal, 
    144 Wn.2d 600
    , 609, 
    30 P. 3d 1255
     ( 2001)). A trial court abuses
    its discretion when it misinterprets a rule. Diaz, 
    175 Wn.2d at 462
    . We apply the same principles
    to interpret        an evidence rule        that   we   apply   when   interpreting    a statute.   Gourley v. Gourley, 
    158 Wn.2d 460
    , 466, 
    145 P. 3d 1185
     ( 2006). We consider the plain language of the rule and when the
    17
    No. 44655 -3 -II
    rule' s meaning is plain on its face, we will give effect to its plain meaning as an expression of the
    intent   of   the   drafting body. Gourley, 
    158 Wn.2d at 466
    .
    ER 615 states,
    At the request of a party the court may order witnesses excluded so that they
    cannot hear the testimony of other witnesses, and it may make the order of its own
    motion.       This   rule   does   not authorize    exclusion of ( 1)
    a party who is a natural
    person, or ( 2) an officer or employee of a party which is not a natural person
    designated as its representative by its attorney, or ( 3) a person whose presence is
    shown by a party to be reasonably necessary to the presentation of the party' s cause.
    We begin       our   interpretation   of   ER 615   by    considering its   plain   meaning.   Gourley, 
    158 Wn.2d at 466
    . In general, the rule gives the trial court broad discretion to exclude witnesses except
    in three      enumerated circumstances.          In those three circumstances, the rule' s language explicitly
    does not authorize exclusion" of witnesses. ER 615. Based on the plain language of ER 615( 2),
    the trial court is without authority to exclude a witness from the courtroom where ( 1) the party is
    not a natural person, (2) the witness is the party' s employee, and ( 3) the party' s attorney designates
    her to be its representative in court.
    A simple application of this rule shows that the trial court misinterpreted it. Multicare is
    the defendant and is a Washington corporation, not a natural person. It is undisputed that Barker
    was Multicare' s employee at the time of trial and that Multicare sought to designate her as its
    representative.         Therefore, under ER 615, the trial court is without authority to exclude Barker
    from the courtroom.
    Accordingly, we hold that the trial court abused its discretion when it denied Multicare' s
    request to designate an employee who is also a fact witness in the case as its in -court representative
    under ER 615.
    18
    No. 44655 -3 -II
    B. MULTICARE' S PROPOSED JURY INSTRUCTION ON THE TAXABILITY OF
    PERSONAL INJURY AWARDS
    Multicare also argues that the trial court erred when it refused to give a jury instruction
    regarding the taxability of personal injury awards and because its proposed instruction is a correct
    statement of law, the trial court erred when it refused to give it.4 We hold that the trial court did
    not abuse its discretion when it refused to give the jury instruction on the taxability of personal
    injury awards.
    We review the trial court' s decision not to give a proposed jury instruction for an abuse of
    discretion.        Stiley   v.   Block, 
    130 Wn.2d 486
    , 498, 
    925 P. 2d 194
     ( 1996).                    We review alleged errors
    of   law in    a   jury   instruction de        novo.   Cox v. Spangler,

    , 442, 
    5 P. 3d 1265
    , 
    22 P. 3d 791
     ( 2000).        Jury instructions are appropriate where they permit the parties to argue their theories
    of the case, are not misleading to the jury, and properly inform the jury of the applicable law. Cox,
    141 Wn.2d at 442.
    In Hinzman             v.   Palmanteer, 
    81 Wn.2d 327
    , 333 -35, 
    501 P. 2d 1228
     ( 1972), our Supreme
    Court upheld a trial court' s refusal to give a jury instruction on the tax consequences of a personal
    injury   award.       In Hinzman, the parents of a seven -year -old girl, who died in a car accident, sued
    the   car' s   driver, its        owner,       and   the driver'   s   employer       for damages.     
    81 Wn.2d at 328
    .   The
    defendants        requested an            instruction that the   jury   should      deduct " reasonable income taxes," among
    other   things from its          award.        Hinzman, 
    81 Wn.2d at 333
    .   Our Supreme Court held that the trial
    court did not err when it refused to give the instruction and based its decision on three principles:
    4 Haskins argues that Multicare failed to preserve the jury instruction issue. But at trial, Multicare
    argued that its proposed jury instruction "deals with the non -taxability of a personal injury award."
    5 RP ( Jan. 29, 2013)                at   184. Multicare   stated, "    We' ll just take an exception to that and preserve
    the issue."        5 RP ( Jan. 29, 2013) at 184. We hold that the issue was preserved.

    1) the plaintiff's tax liability is not pertinent to the issue of damages, ( 2) the amount oftax liability
    that may come due is too speculative, and ( 3) it might be confusing for the jury to introduce an
    income tax issue or question. Hinzman, 
    81 Wn.2d at
    333 -34. The court held that
    w]here extremely high income is involved, injustice to a defendant from
    ignoring future taxes might outweigh injustice to a plaintiff from reducing an award
    of   damages to    allow     for   a speculative   tax   element....    There was no proof of
    extremely high prospective income in the instant case, and even if we were to depart
    from the majority rule, this does not present an appropriate case to do so.
    Hinzman, 
    81 Wn.2d at 334
    .
    In Boeke   v.   International Paint Co. ( California),        Inc., Division One of this court, relying
    on Hinzman, refused to give an instruction that any award of damages would not be subject to
    federal income tax.

    620 P. 2d 103
     ( 1980), review denied, 
    95 Wn.2d 1004
     ( 1981).       In Boeke, Division One held that because the            plaintiffs'   income   was not "`   extremely
    high, "'    as   Hinzman    requires,    the income tax instruction       was not warranted.       27 Wn. App. at 617

    81 Wn.2d at 334

    In Janson v. North Valley Hospital, the plaintiff, whose award was subject to federal
    income taxes, requested a jury instruction out of concern that the jury would think her award was

    971 P. 2d 67

    a U.S. Supreme Court decision that permitted evidence of potential taxes on past and future
    earnings      in federal    court, see   Norfolk & Western Railroad Co. v. Liepelt, 
    444 U.S. 490

    at   906.    Division Three concluded that Liepelt assumed that jurors would wrongfully inflate or
    deflate awards based on inappropriate speculation on tax consequences. Janson, 93 Wn. App. at
    906. The court reasoned that the opposite assumption is just as likely and that instructing the jury

    unnecessarily confusing.              Janson, 93 Wn.            App.   at   906 ( quoting Liepelt, 
    444 U.S. at
    503
    Blackmun, J.,        dissenting)).     The Janson court held that the trial court erred in permitting an
    instruction on the tax consequences of the plaintiff' s award because an instruction on taxes was
    likely to overcomplicate the matter for the jury. 93 Wn. App. at 906.
    Multicare    requested a
    jury instruction that stated, " Any award to plaintiff will not be subject
    to federal income tax, and therefore you should not add or subtract for such taxes in fixing the
    amount of       any   award."   CP     at   163.   However, Haskins is not someone with an extremely high
    income like the Hinzman            court envisioned.            Her exact income is unclear from the record, but
    Haskins testified that       she   is permanently disabled             and receives   just $ 342 a month from Social
    Security. She also testified that since she was diagnosed with cervical cancer, she has been on
    Medicare        and   Medicaid.       This is not the type of high- income plaintiff the Hinzman court
    envisioned whose award might be unjust to the defendant if taxes are not considered.
    Accordingly, we hold that the trial court did not abuse its discretion when it declined to
    give Multicare' s proposed jury instruction on the taxability of personal injury awards.
    CONCLUSION
    We hold that ( 1) it was reversible error to fail to give Haskins' s proposed res ipsa loquitur
    instruction, ( 2) it was not error to permit Multicare to present evidence of past collateral source
    payments, (      3) it was an abuse of discretion to deny Multicare' s request to designate an employee
    who is also a fact witness in the case as its in -court representative under ER 615, and (4) it was not
    an abuse of discretion to decline to give Multicare' s proposed jury instruction on the taxability of

    personal injury awards. Accordingly, we vacate the judgment in Multicare' s favor and remand for
    a new trial.
    A majority of the panel having determined that this opinion will not be printed in the
    Washington Appellate Reports, but will be filed for public record in accordance with RCW 2. 06.040,
    it.is so ordered.
    We concur:
