H.D. STAIR, J.
Plaintiff Consumers Power Company brings the present appeal from a decision of the defendant commission denying plaintiff an increase in its rate of return on common equity.
On November 27, 1974, plaintiff filed an application with the commission requesting several changes in its financial status, including a gas rate increase and an increase in the rate of return on common equity. At a hearing before an administrative law judge, numerous witnesses testified concerning these issues. The two expert witnesses on the rate of return issue recommended that the then current rate of 12.12% be raised. Plaintiff's
The hearing judge found that a reasonable return on the common stock would be in the range of 13% to 14%, and recommended a change in the rate to 13.50%. On appeal to the full commission, the hearing judge's proposal was rejected in favor of leaving the current rate of 12.12% unchanged.
Pursuant to MCLA 462.26; MSA 22.45, plaintiff appealed the commission's finding on the rate of return issue to the Ingham County Circuit Court. On September 15, 1976, the court filed an opinion upholding the commission's ruling maintaining the rate at its existing ratio. Plaintiff has now appealed the decision to this Court.
The first issue raised concerns the sufficiency of the commission's finding. Plaintiff argues that the decision to leave the rate unchanged was unsupported by the evidence, particularly since the testimony of the expert witnesses, including the commission's staff expert, supported a rate between a low of 12.34% and a high of 16%. Plaintiff concedes that the commission was free to reject all of the expert testimony offered, but contends that the holding in fact made, at a rate beneath the recommended range, was not supported by any independent evidence.
The standard for review of an administrative agency ruling is set forth both in the Michigan Constitution and in the Administrative Procedures Act of 1969, 1969 PA 306:
"All final decisions, findings, rulings and orders of any administrative officer or agency existing under the constitution
"(1) Except when a statute or the constitution provides for a different scope of review, the court shall hold unlawful and set aside a decision or order of an agency if substantial rights of the petitioner have been prejudiced because the decision or order is any of the following:
* * *
"(d) Not supported by competent, material and substantial evidence on the whole record." MCLA 24.306; MSA 3.560(206).
Plaintiff cites numerous cases from other jurisdictions where decisions of an administrative agency setting rates at a level below the range recommended by expert witnesses have been either reversed or upheld based upon the existence of independent evidence supporting the lower figure. We find ourselves precluded, however, from engaging in this type of analysis by a more basic problem with the commission's ruling.
Section 85 of the Administrative Procedures Act of 1969 reads as follows:
"A final decision or order of an agency in a contested
The necessity for a detailed finding of fact, as outlined in § 85, is intended to facilitate appellate review by providing a precise statement of what evidence, on the record, supports the agency's ruling. See Viculin v Dept of Civil Service, 386 Mich. 375; 192 N.W.2d 449 (1971), Lamb v John's Tavern, 37 Mich.App. 678; 195 N.W.2d 278 (1972).
Our reading of the commission's holding on the rate of return issue reveals merely conclusional statements in regard to the rejection of the expert testimony and plaintiff's request for an increase in the rate. While there may well be some independent record evidence supporting the decision to retain the existing rate, the opinion does not indicate that evidence in any detail. Before this Court can decide if the commission's ruling was supported by "competent, material and substantial evidence on the whole record", we must be informed of the nature of that evidence. Lacking a
Plaintiff's second issue on appeal needs to be discussed in relation to the remand. In support of its decision, the commission took judicial notice of several developments regarding plaintiff's financial condition at the time of the decision. The standard for the agency's ruling, as previously stated, is that it be supported by evidence "on the whole record". On remand the commission should not consider evidence or take notice of factors that were not properly introduced and made part of the record at the original hearing.
Remanded for proceedings consistent with this opinion. We retain jurisdiction. No costs at this time.
