177 N.W.2d 163
DETROIT EDISON COMPANY
v.
DEPARTMENT OF TREASURY
Calendar No. 12, Docket No. 52,718.
Supreme Court of Michigan.
Decided June 2, 1970.
Fischer, Sprague, Franklin & Ford (Gerald C. Simon and Thomas F. Sweeney, of counsel), for plaintiff.
Frank J. Kelley, Attorney General, Robert A. Derengoski, Solicitor General, and William D. *583 Dexter and Robert J. Taube, Assistant Attorneys General, for defendants.
PER CURIAM:
This appeal is from a summary judgment in the Ingham Circuit in favor of the Detroit Edison Company determining its franchise fee for the years 1959 thru 1966.
The trial court held that since the Michigan Public Service Commission rules and regulations controlled Edison's method of accounting, absent a showing of fraud or mistake, if Edison's accounts were kept according to such rules and regulations, the books of account must be accepted by the Treasury Department and Edison's franchise fee determined according to them. Finding no dispute that the books were so kept, the court entered judgment for Edison.
The Treasury Department maintained that whatever the effect of Michigan Public Service Commission regulations requiring or permitting the keeping of accounts in the manner prescribed by the commission for their purpose of regulating rates, the accounting method of Edison in accord therewith should not preclude the Treasury Department from assaying the effect thereof for the purpose of computing the franchise fee.
This wholly tenable position was considered by the trial judge in Detroit Edison Company v. Corporation & Securities Commission (1962), 367 Mich 104, and his election to reject it in favor of the position urged by Edison that accounting in the Michigan Public Service Commission regulated manner was binding for all purposes was approved by this Court in that case and in Corporation & Securities Commission v. American Motors Corporation (1967), 379 Mich 531.
*584 We are not persuaded that any good purpose would be served by adopting a different ruling now and accordingly we affirm the judgment entered herein. Costs to plaintiff in all three courts.
T.E. BRENNAN, C.J., and T.M. KAVANAGH, ADAMS and T.G. KAVANAGH, JJ., concurred.
DETHMERS and BLACK, JJ., concurred in the result.
KELLY, J., did not sit in this case.
