¶ 1 In this statutory special action, petitioner employee Michael Meiners contends the administrative law judge (ALJ) erred by reducing his workers’ compensation benefits following a hearing on the petition he had filed for rearrangement. We conclude res judicata principles preclude the ALJ from reducing Meiners’s disability compensation and set aside the award.
Factual and Procedural Background
¶ 2 “On review of an Industrial Commission award, we must view the evidence in the light most favorable to sustaining the Industrial Commission’s findings and award.”
Roberts v. Indus. Comm’n,
¶3 In 2004, Meiners filed a petition to reopen pursuant to A.R.S. § 23-1061(H), which the ALJ denied following a hearing. Meiners had also filed a pеtition for rearrangement pursuant to A.R.S. § 23-1044(F),
1
which the Industrial Commission similarly denied. Meiners requested a hearing, at which he testified that, due to a congenital defect, his lower right leg was underdeveloped and his right foot and ankle “do[ ] not work correctly.” He stated that he had be
gun
¶ 4 Meiners’s treating physician, Dr. Harvey Maksvytis, testified Meiners’s back injury “created a chrome and exacerbating” condition, and the congenital defects in his right leg prevented him from compensating for it. Maksvytis stated Meiners’s attempts tо compensate for his back injury resulted in pain and weakness in his right side, which, in turn, would “exacerbate his left side.” Mak-svytis also testified Meiners was “totally] disabled]” and that he could not engage “in any type of gainful employment” without “significant pain.”
¶ 5 Dr. Kurt Schroeder testified Meiners could work a full-time job with some physical restrictions. Schroeder also stated that a 2004 magnetic resonance imaging (MRI) of Meiners’s back revealed “there had been resolution of [the] significant disc rupture,” and that the remaining abnormalities in his back were “from a medical treatment standpoint^] benign.” Schroeder testified it was “extremely unlikely” that Meiners’s pain in his right leg was related to his “left-sided disc rupture.”
¶ 6 After hearing labor market testimony from both parties, the ALJ adopted the testimony of Schroeder and the University’s labor market expert, finding Meiners “could work in a customer service or reservation type position on a fulltime basis.” The ALJ also adopted the University’s labor mаrket expert’s salary calculations and reduced Mein-ers’s award to $329.91. Upon review, the ALJ affirmed its decision reducing Meiners’s benefits. This statutory special action followed.
Discussion
¶ 7 “We will not set aside the award if it is based upon any reasonable interpretation of the evidence.”
Roberts v. Indus. Comm’n,
¶ 8 Meiners argues the ALJ’s reduction of his 1996 award was an impermissible “collateral attack” on that award because it was “final and res judicata.” Because the petition for rearrangement at issue here was filed by Meiners, not the University, we requested supplemental briefing from the parties on whether the ALJ had the authority to reduce Meiners’s award absent a petition filed by the University requesting that relief. The University argues in its supplemental brief that Meiners has waived this issue “by not presenting it in [his] opening brief.”
See Ness v. Western Sec. Life Ins. Co.,
¶ 9 Either an employee or emplоyer may petition for rearrangement pursuant to § 23-1044(F). The Industrial Commission’s regulation, R20-5-134, Ariz. Admin. Code, requires that petition to be a signed writing stating “the basis upon which the rearrangement of compensation is sought” and must include supporting documentation. 3 We find no petition by the University in the record meeting these requirements, nor did it request, in any of the papers it filed with the Commission, or at the hearing, that Mein-ers’s award be reduced.
¶ 10 In its supplemental brief, the University argues
German v. Industrial Commission,
¶ 11 Division One of this court rejected that argument and determined Rule 38 did not “apply to awards which have not become final
and
which have not been preceded by a formal hearing,” and, thus, did not preclude the hearing officer from deciding issues not raised in the petitioner’s petition for hearing.
Id.
at 307,
“[T]he granting of a first motion to rehear the award has the effect of setting aside or vaсating that award and when on rehearing the cause on its merits, the subsequent award supersedes the former.” Petitioner’s timely motion to rehear had the effect of setting aside the [previous] award and opened the matter for a full hearing on the merits. The burden of proof on petitioner to establish a cоmpensable disability remained the same as prior to the initial award.
Id.
at 553,
¶ 12 The University contends that, based on
German
and the fact that the Industrial Commission rejected Meiners’s petition for rearrangement without a formal hearing, his subsequent request for a hearing on that petition “gave the ALJ the authority to review the issue of permanent disability in its entirety and determine whether permanent benefits should be increased, decreased, or left as previously established.” We disagree.
German
only stands for the proposition that an ALJ may reduce or rescind an initial award before it becomes final, unconstrained
¶ 13 In contrast to
German,
Meiners’s original award was entered after a hearing and became final in 1996. That award determined his permanent disability resulted in a forty-two percent reduction in his earning capacity. “After findings and an award are made, the doсtrine of res judicata operates to bar relitigation of issues which were ... decided at that proceeding.”
Pima County Bd. of Supervisors v. Indus. Comm’n,
¶ 14 We find no authority suggesting аn ALJ may find an employee’s earning capacity has increased under § 23-1044(F) absent a petition by the carrier or employer requesting such a determination, thereby providing notice to the employee and the opportunity to contest the request.
4
The only issue before the ALJ was whether Meiners’s earning сapacity had been reduced due to a change in physical condition or other factor arising out of his compensable injury. And, as noted above, the University did not file a petition meeting the requirements of R20-5-134, Ariz. Admin. Code.
See LaWall v. Pima County Merit Sys. Comm’n,
¶ 15 Our conclusion is consistent -with the purpose of workers’ compensation law, which is “to protect the [worker] and to relieve society of the burden caused by industrial accidents.”
English v. Indus. Comm’n,
It has been repeatedly held that the Act should receive a liberal interpretation in favor of the employee. Where there is a doubt as to the [Act’s] construction, that construction should be adopted which will best effect its purpose of compensating the injured employee for his loss of earning power.
Id. Rearrangement allows an employee to petition for an increase in benefits should a condition worsen or earning capacity decrease. To hold an ALJ may reduce an employee’s compensation absent an employer or carrier filing a proper petition to rearrange could discourage an employee from seeking rearrangement, and would be contrary to the remedial purpose of the workers’ сompensation statutes.
¶ 16 At oral argument, the University contended that permitting an ALJ to reduce an award in the absence of a petition filed by the employer or carrier is permissible because such a rule would promote judicial efficiency. 5 It reasons that, because the evidence presented at the hearing would be similar regardless of which party filed the petition, it is more efficient for the ALJ to address the employee’s earning capacity de novo. We are unconvinced. Although the evidence presented could be similar, it is not necessarily so, nor would it necessarily be presented оr argued in the same manner than if the employee did not have to guard against a reduction in benefits. Moreover, any benefit to judicial efficiency does not outweigh the risk of inadequate notice, the policy goals of the workers’ compensation system, or the requirements of R20-5-134, Ariz. Admin. Code.
¶ 17 Because the doctrine of res judicata precluded the ALJ from reducing Meiners’s workers’ compensation benefits, we set aside the award. Thus, we do not address Mein-ers’s remaining arguments.
Notes
. Section 23-1044(F) states:
[A]n award of compensation ... shall be subject to change in ... the following events:
1. Upon a showing of a change in the physical condition of the employee subsequent to such findings and award arising out of the injury resulting in the reduction or increase of the employee’s earning capacity.
2. Upon a showing of a reduction in the earning capacity of the employee arising out of such injury where there is no change in the employee's physical condition, subsequent to the findings and award.
3. Upon a showing that the employee’s earning capacity has increased subsequent to such findings and award.
. The rule that issues not "clearly raised" in the opening brief are waived is not jurisdictional, but instead is a “policy of judicial restraint.”
Childress Buick Co. v. O'Connell,
. That regulation provides, in pertinent part:
A. A petition for rearrangement or readjustment of compensation filed with the Commission under A.R.S. 23-1044(F) shall be in writing. A form is available from the Commission upon request.
B. A party or a party's authorized representative shall sign a petition for rearrangement оr readjustment and include in the petition:
1. A statement of the basis upon which the rearrangement or readjustment of compensation is sought, and
2. Documentation in support of the petition.
C. The petition shall be signed by the employee or the employee's authorized representative, the employer, or, in the case of an insurance carriеr, by its authorized representative, and shall include a statement of the basis upon which the rearrangement of compensation is sought accompanied by supportive documentary evidence.
.
We reject the University's assertion at oral argument that notice may be implied from the evidence produced in discovery. That evidence may reasonably support a reduction in benefits is not notice that a party is actually seeking it.
See, e.g., Mullane v. Central Hanover Bank & Trust Co.,
. The University also argued that it is common practice for an ALJ to reduce an award when an employee petitions to increase it, but could not recall any specific instance in which that had occurred, nor are we aware of any. Meiners disagreed with the University’s contention. In any event, the record before us contains no evidence of such practice. And, even if this practice were pervasive, that does not mean it is correct.
