1 1 Petitioner/Counter-Respondent Jeffery Blaine Harvey (Claimant) appeals an order of a three-judge panel of the Workers' Compensation Court affirming the trial court's order. Claimant asserts that Respondents/Counter-Petitioners Auto Plus of Woodward and Acadia Insurance Company (collectively, Employer) waived a defense based on 85 0.8.Supp.2010
FACTS
1 2 Claimant worked for Employer for nine years installing car windows. Claimant filed a Form 3 April 2, 2010, alleging cumulative trauma injuries to both hands, both arms, both shoulders, and spine from pounding windows with his hands and using vibrating hand tools. Claimant continued to work for Employer after he filed his Form 8. The owner of Employer died, and the business closed May 28, 2010. Claimant alleged the last date of exposure was May 28, 2010. After Employer closed, Claimant opened and operated his own car window installation business, Max Auto Glass, at the same location.
T3 Employer denied compensability, and the trial court appointed Dr. Richard Ruffin as the Independent Medical Examiner October 29, 2010. Claimant filed a Form 9 Motion for Trial seeking medical treatment and surgical authorization March 31, 2011, Employer requested that Claimant be evaluated by Dr. Kent C. Hensley. Dr. Hensley evaluated Claimant April 28, 2011 and issued a report finding no eumulative trauma and noting that if work with Employer was injurious, then work in subsequent employment was also injurious. Dr. Hensley's report was provided to Claimant a few days before trial. Employer filed a Form 10 and asserted the affirmative defense of subsequent aggravation May 4, 2011, one day before trial.
T4 The case proceeded to trial May 5, 2011. At trial, Employer raised a § 11(B)(5) defense and argued Claimant's subsequent employer should be liable for benefits. Claimant argued Employer waived the defense, because it was not specifically pleaded on a Form 10. On May 9, 2011, the trial judge issued an order finding Claimant sustained compensable cumulative trauma injuries to his hands, wrists, arms, and elbows. The trial court rejected Claimant's argument that the § 11(B)(5) defense was waived and noted that the defense was adequately explored during Claimant's deposition, Dr. Ruf-fin's deposition, and by pleadings on file as of the day of trial. However, the trial court denied Employer's defense of subsequent aggravation and found "Claimant has not suffered injurious exposure as a self employed person (work dropped off)." The trial court continued to say that Employer's "85 0.8. § 11(b)(5) defense is DENIED based on DR. RUFFIN'S deposition of MARCH 8, 2011 and based on claimant's testimony about reduced tasks and a change in tasks following
STANDARD OF REVIEW
15 First, we must determine the proper standard of review. Claimant argues the any competent evidence standard of review applies, because the injury occurred prior to the effective date of 85 0.8.2011 § 340(D). Employer argues this Court should determine whether the panel's findings were against the clear weight of the evidence, as set forth in 85 0.8. § 340(D). Claimant and Employer filed their petitions for review August 26, 2011, the same day 85 0.8. § 340(D) went into effect, The 2011 amendment to the Workers' Compensation Code provides:
After the effective date of this act, regardless of the date of injury, the Supreme Court may modify, reverse, remand for rehearing, or set aside the order or award upon any of the following grounds:
1. The Court acted without or in excess of its powers;
2. The order or award was contrary to law;
8. The order or award was procured by fraud; or
4, The order or award was against the clear weight of the evidence.
85 O.S. § 340(D). Despite recent amendments to the Workers' Compensation Code and multiple decisions from appellate courts, uncertainty pervades. Clarification of the proper standard of review is warranted.
1 6 Prior to the 2010 amendment to 85 0.8. § 3.6, the standard of review was different depending on whether the review was by a three-judge panel of the Workers' Compensation Court or by the Supreme Court. In Parks v. Norman Municipal Hospital,
T7 The 2010 amendment to 85 O.. § 3.6(C) provided:
The Supreme Court may modify, reverse, remand for rehearing, or set aside the order or award upon any of the following grounds:
*414 1. The Court acted without or in excess of its
2. The order or award was contrary to law;
3. - The order or award was procured by fraud; or
4. The order or award was against the clear weight of the evidence.
85 0.S.Supp.2010 § 3.6(C) (repealed). The 2010 amendment took effect November 1, 2010 and authorized the Supreme Court to review an order or award to determine whether it was against the clear weight of the evidence. In Dunlap v. Multiple Injury Trust Fund,
T8 In direct response to the Court's decision in Dunlap, the Oklahoma Legislature again amended and renumbered § 8.6(C), adding the language: "After the effective date of this act, regardless of the date of injury ..." 85 0.8.2011 § 340(D), effective August 26, 2011. All other language from the 2010 statute remained the same.
T9 Claimant asserts that despite 85 O.S. § 340(D), the law in effect at the time of the injury should apply. Claimant's date of last exposure was May 28, 2010. On that day, any competent evidence was the standard of review. - Claimant first argues that the Legislature's attempt at instructing the Oklahoma Supreme Court on the standard of review in § 340(D) is invalid under the separation of powers doctrine and violates Article IV, § 1 of the Oklahoma Constitution. Employer argues that standards of review are established by either appellate practice or explicit statutory command and, therefore, the Legislature is permitted to establish the standard of review for a particular matter.
110 Article IV, § 1 of the Oklahoma Constitution provides:
The powers of the government of the State of Oklahoma shall be divided into three separate departments: The Legislative, Executive, and Judicial; and exeept as provided in this Constitution, the Legislative, Executive, and Judicial departments of government shall be separate and distinct, and neither shall exercise the powers properly belonging to either of the others.
art. IV, § 1. Every legislative act is presumed to be constitutional and will be upheld unless it is clearly, palpably, and plainly inconsistent with the Constitution. City of Edmond v. Vernon,
T11 Claimant has failed to cite a single case where the Oklahoma Supreme Court or Court of Criminal Appeals determined a statutorily prescribed standard of review was unconstitutional because it violated the separation of powers doctrine, and we have yet to discover such case
For some few trial court determinations, the question of what is the standard of appellate review is answered by relatively explicit statutory command. See, e.g., 42 U.S.C. § 1988 ("[The court, in its discretion, may allow the prevailing party ... a reasonable attorney's fee"). For most others, the answer is provided by a long history of appellate practice.
Id. at 558,
{12 Alternatively, Claimant argues that even if the statute is constitutional, it cannot be applied retroactively to cases that have previously been tried to a trial court and reviewed by a three-judge panel, because the amendment affects the substantive rights of the parties. Employer responds and argues that the clear language of the 2011 amendment evidences the Legislature's intent that Oklahoma appellate courts apply the against the clear weight of the evidence standard of review retroactively. Employer further suggests that the standard of review is a matter of procedure and, therefore, may be applied retroactively.
113 The Supreme Court of Okla homa summarized the long-standing principles regarding the retroactive and prospective application of statutes in Cole #. Silverado Foods, Inc.,
Absent a plain legislative intent to the contrary, statutes are generally presumed to operate prospectively only. Legislation that is general in its terms and impacts only matters of procedure is presumed to be applicable to all actions, even those that are pending. - Statutes that relate solely to remedies and hence affect only modes of enactments which do not*417 create, enlarge, diminish, or destroy accrued or contractual rights-are generally held to operate retroactively and apply to pending proceedings (unless their operation would affect substantive rights).
Id. 18,
[Glenerally, the law in effect at the time of the employee's injury controls. ok
Statutes are typically not given retroactive effect unless the Legislature has made its intent to do so clear. Any doubts must be resolved against a retroactive effect. Here, the Legislature provided no language expressing its intent for § 11(B)(5) to apply retroactively. The absence of such intent is likely because substantive rights of the affected parties would have been violated.
The right to compensation and the obligation to pay such benefits becomes vested and fixed by law at the time of the claimant's injury. Such rights cannot be affected by after-enacted legislation. The statutes in force on the date of injury form a part of the contract and determine the rights and obligations of the parties. No subsequent amendment can operate retrospectively to affect in any way the substantive rights and obligations which are fixed.
Id. 1% 12-14,
114 The Legislature clearly expressed its intent that § 340(D) was to be applied retroactively when it amended the statute to include the language: "After the effective date of this act, regardless of the date of injury, the Supreme Court may modify, reverse, remand for rehearing, or set aside the order or award [if] ... [tlhe order or award was against the clear weight of the evidence." 85 0.8.2011 § 840(D) (emphasis added). The Supreme Court in Dunlap held that the against the clear weight of the evidence standard of review established in 85 0.8.Supp.2010 § 8.6(C) did not apply to appeals where the injury underlying the claim occurred prior to the effective date of the 2010 amendment. However, Duniap interpreted the 2010 statute, which did not contain plain language expressing the Legislature's intent to apply the statute retroactively. The Legislature amended the statute in 2011 by adding plain language expressing its intent that § 840(D) is to be applied retroactively.
T15 Furthermore, generally the standard of review is a matter of procedure and, therefore, may be applied retroactively without affecting the substantive rights of the parties. Although the Oklahoma Supreme Court has not specifically ruled on whether standards of review are procedural or substantive, several other jurisdictions have determined standards of review are procedural and may be applied retroactively.
116 We are not persuaded by Claimant's argument that if one party prevails at trial under the any competent evidence standard of review but loses when the against the clear weight of the evidence standard of review is applied on appeal, the standard of review has affected the party's substantive rights. The standard of review prescribed in § 340(D) does not alter the burden of proof at trial. It remains that the employee has the burden of proof to establish by a preponderance of the evidence that the injury was caused by the employment. See 85 0.98.2011 § 308(10)(a). - Furthermore, Claimant was subject to the clear weight of the evidence standard of review when he sought review from the three-judge panel. Prior to the 2011 amendment, a three-judge panel of the Workers' Compensation Court could reverse or modify the trial judge's decision only if it determined that the decision was against the clear weight of the evidence or contrary to law. See 85 O.8.Supp.2010 § 3.6(A); Parks,
[17 Our determination of the proper standard of review is consistent with Division 2 and Division 4 of the Court of Civil Appeals. Division 2 applied the against the clear weight of the evidence standard of review in Okla. Dep't of Mental Health & Substance Abuse v. Pierce,
118 We hold that the Legislature clearly expressed its intent that 85 0.8. § 340(D) be applied retroactively and that the statute does not affect the substantive rights of the parties. Therefore, § 340(D) provides the proper standard of review for this appeal.
85 0.8. § 11 (B)(5) DEFENSE NOT WAIVED
T 19 Claimant appeals the finding that Employer had not waived its § 11(B)(5) defense. Claimant argues the defense was waived because Employer did not specifically plead the affirmative defense in a Form 10. Claimant relies on Workers' Compensation Court Rule 16:
A general denial or failure to timely file a Form 10 or Form 10M shall be taken as admitting all allegations in the claim form except jurisdictional issues.... Unless excused by the Court for good cause shown, denials and affirmative defenses shall be asserted on the Form 10 or Form 10M or shall be waived.
Rule 16(B)(2), Rules of the Workers' Compensation Court, 85 0.S.Supp.2006, Ch. 4, App. (emphasis added). Claimant asserts that because Employer did not timely file a Form 10, it waived the subsequent aggravation defense. Rule 19 provides:
D. - In all cases, the respondent shall file a Form 10 or Form 10M no later than thirty (30) days after the filing of the Form 9.
The Form 10 or Form 10M may be amended at any time, not later than twenty (20) days prior to the date of trial.
G. The provisions of this rule may be exeused by the Court for good cause shown.
Rule 19, Rules of the Workers' Compensation Court, 85 0.$.8upp.2006, Ch. 4, App. (emphasis added). Claimant filed his Form 9 March 31, 2011. Employer filed a Form 10 November 9, 2010, but no affirmative defenses were asserted. It was not until May 4, 2011, one day before trial, that Employer filed a Form 10 and asserted subsequent aggravation as an affirmative defense.
1 20 Employer responds that its § 11(B)(5) defense was not a surprise to Claimant, and the trial court found good cause for excusing the failure to assert an affirmative defense in a timely filed Form 10 when it stated in the order that the § 11(B)(5) defense "was adequately explored during claimant's deposition, DR. RUFFIN'S deposition and by pleadings on file as of the day of trial." Employer asserts that strict adherence to Rules 16 and 19 is not required as the Workers' Compensation Court has the authority to relax rules within its discretion.
{21 We hold that it was within the trial court's discretion to allow Employer to
DENIAL OF 85 0.8. § 11(B)(5) DEFENSE WAS NOT AGAINST THE CLEAR WEIGHT OF THE EVIDENCE
122 Employer appeals the denial of its § 11(B)(5) defense. Employer argues that finding a compensable injury is against the clear weight of the evidence because Claimant was injuriously exposed to the trauma in his subsequent employment for a period of more than ninety (90) days. Employer asserts that Claimant's subsequent employer is liable for any and all benefits, Title 85, § 11(B)(5) provides:
Where compensation is payable for an injury resulting from cumulative trauma, the last employer in whose employment the employee was last injuriously exposed to the trauma during a period of at least ninety (90) days or more, and the insurance carrier, if any, on the risk when the employee was last so exposed under such employer, shall alone be liable therefor, without right to contribution from any pri- or employer or insurance carrier,
85 0.8. § 11(B)(5). Employer suggests that Claimant was self-employed at Max Auto Glass for more than ninety (90) days, and Claimant admitted that while self-employed, he pounded windows with his hands and used vibratory tools. Employer further relies on Dr. Hensley's report and Dr. Ruffin's deposition. Dr. Ruffin testified that Claimant's subsequent employment aggravated or maintained his condition. Employer asserts that after Claimant became self-employed, he continued to be exposed to the trauma that caused or contributed to his injury; therefore, Max Auto Glass should be liable for the compensation payable for an injury resulting from the cumulative traumas.
123 Claimant argues that he was not "injuriously" exposed to the trauma during subsequent employment. Claimant claims he significantly reduced his exposure to vibrating hand tools after becoming self-employed and, therefore, his exposure to the trauma was not "injurious." - Claimant also relies on his own testimony at trial and Dr. Ruffin's deposition testimony. Dr. Ruffin testified that the need for surgery existed prior to Claimant becoming self-employed and that subsequent employment did not make Claimant's injury worse. Claimant also suggests Employer should have joined Max Auto Glass to the claim.
1 24 The Court of Civil Appeals has considered similar facts in Southern Material Handling Co. v. Falling, 2006 OK. CIV APP 81,
[It would appear that, if the proof demonstrates the job-related exposures to a risk of cumulative trauma injury in the last employment kave not caused or contributed to the resulting disability, § 11(B)(B) would permit imposition of liability for the full extent of cumulative-trauma-related disability on the previous employer.
Id. 115,
[ 25 The elaimant in Neel! stopped working for the employer several months after he reported problems with his hands.
126 The Court of Civil Appeals adopted the following burden shifting analy-sig:
For cumulative traumas injury, the claimant must present lay testimony of the nature of the work that exposed him to the cumulative trauma injury and expert medical evidence establishing a nexus between the activity and the disability for which compensation is sought,. - The employer against whom the claimant is proceeding may refute the claimant's evidence with evidence that the conditions of employment could not have caused the injury, or that the injury was caused by exposure during the last 90 days of employment with another employer.
Id. 17, 186 P.8d at 786 (emphasis added).
127 In the present case, it is undisputed that Claimant has been self-employed for a period of more than ninety (90) days. However, the parties presented conflicting evidence on the issue of whether Claimant was injuriously exposed to the trauma in his subsequent employment. Employer offered Claimant's testimony that he continued to install car windows and train his son in window installation while self-employed. Employer also pointed to a comment in Dr. Hensley's report that if the work with Employer was injurious, then the work in subsequent employment was also injurious. Employer further relied on Dr. Ruffin's deposition testimony that using vibratory tools and pounding glass while self-employed "aggravates" Claimant's condition.
128 Claimant offered his own testimony that work dropped off after he opened his
29 We hold that it was not against the clear weight of the evidence to find Claimant had not suffered injurious exposure to the trauma in his subsequent employment. Claimant's testimony and Dr. Ruffin's testimony support the conclusions that exposure to the trauma while self-employed did not cause or contribute to the resulting disability, that subsequent employment did not make the cumulative trauma injuries worse, and that Claimant's injuries are attributable to cumulative trauma sustained while working for Employer.

We recognize some uncertainty remains as to whether § 340(D) applies to appeals pending but not yet decided as of the effective date of the statute. The Court of Civil Appeals has applied the against the clear weight of the evidence standard of review to appeals filed before August 26, 2011 but not decided until after August 26, 2011. See Durant Metal Shredding v. Stapleton,2012 OK CIV APP 35 , ¶ 5,274 P.3d 852 , 853; Lee v. Sundance Rehab. Corp.,2012 OK CIV APP 77 , ¶ 5,284 P.3d 469 ; Scott v. Sprint PCS,2012 OK CIV APP 36 , ¶ 6,274 P.3d 173 , 174. The Supreme Court of Oklahoma applied the any competent evidence standard of review in Nomac Drilling LLC v.

In Nomac and Espino-sa, the Court of Civil Appeals had previously decided the cases under the any competent evidence standard of review prior to August 26, 2011, but the Oklahoma Supreme Court did not review the appeals until after August 26, 2011. See Nomac,2012 OK 45 , ¶ 8,277 P.3d at 1284 (decided May 8, 2012); Espinosa,2011 OK 81 , ¶ 21,264 P.3d at 1196-97 (decided October 4, 2011).
