This is an original proceeding in which this court issued an alternative writ of mandamus directed to the defendant commanding that he vacate two orders entered by him in a case рending before him or show cause why he had not done so. The defendant demurred to the alternative' writ and the question before us is whether the facts stated in the writ entitle petitiоners to a peremptory writ.
On September 2, 1966, Calvin F. Sutton, a workman covered under the Workmen’s Compensation Law, sustained an accidental injury in the course of his emplоyment and submitted a claim to the State Compensation Department.
On September 18, 1967, the Workmen’s Compensation Board, through its Closing and Evaluation Division, determined that Sutton had suffеred a compensable injury and granted him an award for permanent partial disability equal to 15 per cent loss of an arm due to an aggravation of a preexisting сondition. Sutton was dissatisfied with the award and asked for a hearing. A hearing was held and thereafter on May 29, 1968, Norman F. Kelley, a hearing officer for the Workmen’s Compensation Bоard, entered his opinion and order directing that Sutton be granted an additional award' equal to 20 per cent loss of an arm, making a total award for permanent pаrtial disability equal to 35 - per cent loss of an arm.
Thereafter the State-Compensation.Department requested the Workmen’^ 'Compensation Board to re *469 view the order of the Hearing Officer, Norman F. Kelley. On September 9, 1968, the Workmen’s Compensation Board entered an order reversing the award of Hearing Officer Kelley and reinstating the original award equal to 15 per cent loss of an arm.
Thereafter Sutton appealed to the Circuit Court for Lane County from the order of the Workmen’s Compensatiоn Board. Thereafter on September 24, 1968, the Workmen’s Compensation Board transmitted to the Circuit Court for Lane County the record of proceedings before the Workmen’s Compensation Board.
The circuit court held a hearing, after which it entered an order containing the following recital of the reasons for the entry thereof:
“The сourt being desirous of further information in regard to the expertise that the court is to be guided by in view of the recent decision of the Supreme Court of the State of Oregon in the case of Romero vs. State Compensation Department, 86 Adv Sh 815, now therefore, the court in order to be fully advised in the premises; determines and finds that it must remand the above entitled matter back to the Hearing Officer to take evidence and make findings in regard to the training, experience, qualifications and expertise of the Closing and Evaluation Section of the Workmen’s Compensation Board, and the individuals who are members of and comprise the Closing and Evaluation Section of the Workmen’s Compensation Board, the Hearing Officer, Norman F. Kelley, who made the Opinion and Order dated May 29, 1968 involved in this proceeding, and of the members of the Workmen’s Compensation Board who determined the questions involved herein and participated in the determination made by the Workmen’s Compensation Board as indicated by the Order on Review of the Workmеn’s Compensation Board dated *470 September 9, 1968, to-wit: Marion E. Cady, Commissioner, and James Redman, Commissioner,
In accordance with the foregoing findings the court ordered as fоllows:
“ORDERED that the above entitled cause be remanded back to the Hearing Officer of the Workmen’s Compensation Board to take evidence and to make findings as tо the training, experience, qualifications and expertise of the Closing and Evaluation Section of the Workmen’s Compensation Board and the individuals who comprise аnd are members of the Closing and Evaluation Section of the Workmen’s Compensation Board, the Hearing Officer, Norman P. Kelley, who made and entered the Opinion and Order hеrein dated May 29, 1968 and of Marion E. Cady, Commissioner, and James Redman, Commissioner, members of the Workmen’s Compensation Board who participated in determining the issues involved аs contained in the Order on Review of the Workmen’s Compensation Board dated September 9, 1968, which Order is the subject of this appeal and judicial review.”
In
Romero v. State Compensation Department,
“Although we are expeeted to review the record de novo, we feel that under the circumstances of this case we have no criteria for fixing the degree of disability or for deciding which of the three different percentages fixed in the preceding adjudications below comes closest as a measurement of plaintiff’s loss. Under these circumstances we feel that the appraisal made by the Hearing Officer and which was affirmed by the Board should be *471 adopted. As сounsel for plaintiff at the hearing admitted, ‘Much of a disability rating is based, and very properly so, on the subjective complaints of pain.’ In this subjective area the opportunity to observe the claimant and the other witnesses is of prime importance. The Hearing Officer is in a position to make this observation and we are not. Moreоver, although we must review the record de novo, we are entitled to take into account the administrative agency’s expertise which develops out of dealing with hundreds of similar cases. As has been pointed out, ‘industrial commissions generally become expert in analyzing certain uncomplicated kinds of medical facts [and we would add non-medical facts also], particularly those bearing on industrial causation, disability, malingering and the like.’ 2 Larson’s Workmen’s Compensation, § 79.53, p 303 (1961). Further, it would seem that in the type оf case we have before us, where the criteria for appraising disability is at best vague and highly subjective, the administrative agency should have some leeway in develоping, if possible, a pattern of decision-making by a comparison of the many cases which are presented to it.”
Defendant contends (1) that the circuit court is also required to review the record de novo, (2) that our decision in Romero requires him “to give some evidentiary weight” to the administrative determinations, and (3) that he is entitled to know the degree of expertise possessed by the various administrative personnel so that he can decide which of the administrative opinions is entitled to the most weight.
Defendant miscоnstrues our opinion. We did not imply that the administrative findings were entitled to “evidentiary weight.” We held merely" that in reviewing de novo the degree of disability" the reviewing court is entitled to tаke into account “the administrative agency"’s expertise which develops out of deal
*472
ing with hundreds of similar cases.” The reviewing court must decide in each case to what extent it will be persuaded by the administrative findings.
Lucke v. State Comp. Dept.,
We further point out that the expertise about which we wrote in
Romero
was not the experience of any individual administrative officer, but the expertise of the administrative agency as a whole. In
Ryf v. Hoffman Construction Company,
“In reviewing Workmen’s Compensation cases it is not proper for us to consider the special talents or knowledge of any individual judge in the field of Workmen’s Compensation law or any other area of the law. However, it is proper for us to consider the expertise of a government agency as a whole, whether an administrative body or a trial court. This was the import of our holding in Romero v. State Compensation Dept.,250 Or at 372-373 ,440 P2d 866 (1968) when we said:
“ * * [W]e are entitled to take into account the administrative agency’s expertise which develops out of dealing with hundreds of similar cases.’
“As the present case illustrates, we may decide that the administrative offiсer erred in rejecting or accepting certain evidence or erred in some other procedural way. And we are tree to exercise our judgment in the aрpraisal of the evidence to the extent that we can do so from an examination of the record. But this is not in derogation of the basic idea expressed in Romero.”
The order of defendant requiring the hearing officer to investigate and report in regard to the training, experience, qualifications and expertise of the admin istrative personnel designated in the orders *473 of the defendant would he of no value and would necessarily interfere with and impair the efficiency and integrity of the agency involved. We therefore find it necessary to issue a peremptory writ.
It is so ordered.
