Atchison, Topeka and Santa Fe Railroad Co. (Santa Fe) appeals a trial court judgment entered after a jury verdict awarding Steven 0. Kauzlarich (Kauzlarich) $1,500,000 in damages under the Federal Employers’ Liability Act, 45 U.S.C. §§ 51-60 (1988) (“FELA” or “Act”). After the trial court denied Santa *256 Fe’s motion for new trial and alternative motion for remittitur, Santa Fe appealed. The Missouri Court of Appeals, Western District, affirmed. This Court granted transfer to decide whether the trial court erred in refusing to give Santa Fe’s proffered instruction on mitigation of damages. The judgment of the trial court is reversed and the cause is remanded for a new trial on damages.
On October 6,1990, Kauzlarich was injured while employed as a rear brakeman for Santa Fe. Shortly after Kauzlarich boarded a stationary engine in Santa Fe’s Argentine, Kansas, yard, a second moving Santa Fe train hit the engine, throwing Kauzlarich to the floor. He suffered head and neck injuries. Kauzla-rich never returned to his position as a brakeman. Except for a brief period when he attempted to train for a Santa Fe management position, he did not again return as an employee of Santa Fe.
On April 9, 1991, Kauzlarich commenced this action against Santa Fe asserting a claim for personal injury under the FELA. Five days before trial, Santa Fe filed an amended answer admitting liability and asserting an affirmative defense based on Kauzlarich’s duty to mitigate damages. The ease proceeded to trial solely on the issue of damages.
Following a five day jury trial, the court entered judgment on the jury’s verdict awarding Kauzlarich $1,500,000 in damages. The trial court denied Santa Fe’s motions for a new trial and for remittitur. Santa Fe raised five points on appeal, and the court of appeals affirmed. In its briefs before this Court, Santa Fe raised only the mitigation of damage instruction issue; therefore, that point remains the sole point on appeal. Rule 83.08.
When adjudicating FELA cases, a state court is bound by federal substantive law.
St. Louis Southwestern Ry. v. Dickerson,
At the conclusion of all the evidence, Santa Fe tendered Instruction H:
With respect to any claimed loss of earnings, if you believe that plaintiff failed to act as an ordinarily prudent person and failed to minimize his damages, you must not award plaintiff such damages as might have been prevented by reasonable efforts on his part. 1
The trial court rejected Instruction H because it was not in the Missouri Approved Jury Instructions (MAI). Instead, the jury was instructed on the issue of damages only by a modified version of MAI No. 8.02, which read:
In assessing damages for plaintiff, you must award plaintiff such sum as you be *257 lieve will fairly and justly compensate plaintiff for any damages you believe he sustained and is reasonably certain to sustain in the future as a result of the occurrence mentioned in the evidence. Any award of future pecuniary damages must not be included at present value. Any award you make is not subject to income tax.
In support of the trial court’s rejection of instruction H, Kauzlarich does not contend that an instruction not in MAI must be refused; rather, he asserts that the question of mitigation of his damages is adequately submitted to the jury by MAI 8.02, as modified.
Ten years ago, with Missouri parties before it, the United States Supreme Court addressed a similar issue in the context of the FELA In
St. Louis Southwestern Ry. v. Dickerson,
The United States Supreme Court reversed the trial court’s judgment and stated:
As a general matter, FELA cases adjudicated in state courts are subject to state procedural rules, but the substantive law governing them is federal. Although the Court’s decisions in this area “point up the impossibility of laying down a precise rule to distinguish ‘substance’ from ‘procedure,’ ” Brown v. Western R. of Alabama,338 U.S. 294 , 296 [70 S.Ct. 105 , 106,94 L.Ed. 100 ] (1949), it is settled that the propriety of jury instructions concerning the measure of damages in an FELA action is an issue of “substance” determined by federal law. Norfolk & Western R. Co. v. Liepelt,444 U.S. 490 , 493 [100 S.Ct. 755 , 757,62 L.Ed.2d 689 ] (1980). Accordingly, petitioner’s contention that it was entitled to a jury instruction on present value cannot be dismissed on the ground that such an instruction is not to be found in [MAI]. Whether such an instruction should have been given is a federal question.
Dickerson,
The
Dickerson
court then noted that existing federal law clearly provided that when future payments or other pecuniary benefits are anticipated, the verdict should be made up on the basis of their present value only,
Chesapeake & Ohio Ry. v. Kelly,
The question of whether Santa Fe is entitled to a separate mitigation of damages instruction, then, requires a determination of whether the issue of mitigation of damages in an FELA case is a substantive matter under federal law so as to require the trial court to submit it. This Court finds that it is. It is well settled that an FELA plaintiff is entitled to recover the difference between what he or she was able to earn before the injury and what he or she earned or could have earned
*258
after the injury.
Bissett v. Burlington N. R.R.,
Because the issue of mitigation of damages in an FELA case is a substantive matter under federal law, the trial court’s refusal to allow instruction of the FELA jury on mitigation of damages is at odds with federal law on a federal question and was error.
Kauzlarich contends that Santa Fe was not prejudiced by the trial court’s refusal to submit tendered Instruction H. He rests his contention on the assertion that MAI 8.02 adequately instructed the jury on the mitigation issue. The error of his contention, the insufficiency of MAI 8.02 in an FELA case as a matter of federal substantive law, is discussed above. In this case, the jury awarded damages to the plaintiff. Under these circumstances, it cannot be said that the defendant was not prejudiced.
Kauzlarich proffers a number of additional bases in support of the trial court’s refusal to submit Instruction H to the jury. He contends that the evidence did not support a mitigation of damages instruction. Kauzlarich is incorrect. To be charged to the jury, an issue submitted in an instruction “must be supported by substantial evidence from which the jury reasonably could find such issue.”
Egelhojf v. Holt,
In further attempt to support the trial court’s refusal of Santa Fe’s instruction, Kauzlarieh maintains that the defendant failed to raise the defense of mitigation properly. Santa Fe’s original answer to Kauzla-rich’s petition failed to plead the affirmative defense of mitigation of damages. Santa Fe’s amended answer, which first raised the mitigation defense, was filed without leave of court or written consent of the adverse party just five days before trial. Relying on Rule 55.33(a) (1993), Kauzlarieh maintains that the amendment was defective and that the defendant waived its mitigation of damages defense. See also Rule 55.08 (1993) (“In pleading to a preceding pleading, a party shall set forth affirmatively ... any other matter constituting an avoidance or affirmative defense.”).
Kauzlarieh ignores subparagraph (b) of Rule 55.33 (1993):
When issues not raised by the pleadings are tried by express or implied consent of the parties, they shall be treated in all respects as if they had been raised in the pleadings. Such amendment of the pleadings as may be necessary to cause them to conform to the evidence and to raise these issues may be made upon motion of any party at any time, even after judgment; but failure so to amend does not affect the result of the trial of these issues.
See also Rombach v. Rombach,
Kauzlarieh additionally maintains that Santa Fe waived its right to contest the trial court’s refusal of tendered Instruction H because it failed to object to the trial court’s ruling. Kauzlarich’s contention is incorrect; counsel did not need to object to the refusal of any instructions that he or she requested. Rule 70.03 (1993).
Kauzlarieh also contends that tendered Instruction H is not in proper form in three respects: it fails to include defendant’s burden of proof; it creates a double standard on proof of damages; and it does not correctly state the law.
Kauzlarieh is incorrect in his contention that an FELA mitigation of damages instruction must contain specific language instructing the jury that Santa Fe carried the burden of proof. Although Santa Fe has the burden of proof on the issue, no language in the instruction to that effect is necessary because the burden of proof was clearly and properly set out by MAI No. 3.01. The Notes on Use to MAI 3.01 state that a burden of proof instruction is to be given in every civil case, and it must be MAI 3.01 unless another burden instruction, specific to certain causes of action, is provided. The second sentence of MAI 3.01 clearly sets forth the standard for burden of proof of all claims for all parties: “The burden of causing you to believe a proposition of fact is upon the party who relies upon that proposition.” The Committee Comment to MAI 3.01 demonstrates that this sentence is sufficient to cover Santa Fe’s burden of proof: “It is no longer necessary to modify the instruction specifically to refer to the burden of proof on an affirmative defense or a counterclaim because the second sentence of the instruction covers each party’s burden of proof.” Although not bound to follow MAI committee comments, this Court carefiilly considers them.
See Peak v. W.T. Grant Co.,
Kauzlarieh relies on two cases,
Jones v. Consolidated Rail Corp.,
In
Jones,
the United States Court of Appeals, Sixth Circuit, held it was reversible error for the trial court to submit to the jury a mitigation instruction without clear instruction as to which party carried the burden of proof on the issue.
Jones,
In
Holley,
the Missouri Court of Appeals, Eastern District, held that the trial court did not err in refusing to tender a mitigation instruction because the proffered instruction, among other things, provided no guidance with respect to which party bears the burden of proof.
Holley,
Kauzlarich is also incorrect in his contention that Santa Fe’s tendered instruction improperly instructs the jury with a second burden of proof. He argues that in stating the jury must not award damages which “might” have been prevented by him, the instruction misleads the jury. The argument miseharacterizes the language of the instruction. The verb “might” does not imply a second burden of proof; it merely directs the jury to reduce its damage award by that amount Kauzlarich may have prevented “by reasonable efforts on his part.” Although imprecise, the term “might” in the instruction properly charged the jury under the law of mitigation.
Kauzlarich further assails Instruction H on the ground that it fails to state the law in that it did not instruct that the plaintiff has a legal duty to mitigate his damages. The alleged defect does not render the instruction improper. When no instruction can be found in MAI, an appropriate instruction not in MAI must follow the substantive law and be written so that it can be readily understood by a jury composed of ordinary people.
Bayne v. Jenkins,
For the foregoing reasons, the judgment of the trial court is reversed and the cause is remanded for a new trial on the issue of damages.
Notes
. Tendered Instruction H closely follows the model instruction set forth in Manual of Model Civil Jury Instructions for the District Courts of the Eighth Circuit § 7.06A, Notes on Use (1995).
