560 P.2d 522 (1977)
STATE of Montana ex rel. Bruce A. KOSENA, d/b/a The Pub, Relator,
v.
The DISTRICT COURT OF THE FIRST JUDICIAL DISTRICT of the State of Montana, IN AND FOR the COUNTY OF LEWIS AND CLARK, the Hon. Arnold Olsen, Judge presiding, Respondents.
No. 13700.
Supreme Court of Montana.
Decided February 22, 1977.
Submitted February 10, 1977.
Smith & Harper, Helena, Robert T. Cummins, Helena, for relator.
PER CURIAM:
The application for a writ of supervisory control to review and reverse the district *523 court's denial of summary judgment to relator is denied and this proceeding dismissed.
For the benefit of counsel practicing before this Court in future proceedings we set forth the following reasons for this denial and dismissal. An order denying summary judgment is not an appealable order. Rule 1, M.R.Civ.App.P. Such an order is reviewable on appeal from a final judgment. Rule 2, M.R.Civ.App.P. To permit review of such order prior to final judgment through the device of supervisory control or other extraordinary writ is to accomplish indirectly that which cannot be done directly.
An order denying summary judgment is nonappealable in the absence of a statute authorizing such appeal. 10 Wright & Miller, Federal Practice & Procedure: Civil § 2715; 6 Pt. 2 Moore's Federal Practice, ¶ 56.21[2]; Switzerland Cheese Asso. v. Horne's Market, Inc., 385 U.S. 23, 87 S.Ct. 193, 17 L.Ed.2d 23; United States v. Florian, 312 U.S. 656, 61 S.Ct. 713, 85 L.Ed. 1105, rehearing denied 312 U.S. 715, 61 S.Ct. 738, 85 L.Ed. 1145. Also see: Anno: Reviewability of Federal Court's Denial of Motion for Summary Judgment, 17 L.Ed.2d 886.
Under state summary judgment procedures, the vast majority of cases have held likewise. See: Reviewability of Order Denying Motion for Summary Judgment, 15 A.L.R.3d 899, 902, for a collection of cases from state jurisdictions; 4 Am.Jur.2d, Appeal & Error, § 104.
The reason for the rule is that an order denying summary judgment is interlocutory in character, not res judicata (Fraser v. Doing, 76 U.S.App.D.C. 111, 130 F.2d 617) and subject to later review if circumstances warrant:
"* * * And if good reason is shown why the prior ruling is no longer applicable or for some other reason should be departed from, the court can and should entertain a renewed motion in the interest of effective judicial administration." 6 Moore's Federal Practice, ¶ 56.14[2], p. 56-363.
Also see: Brown v. Midland National Bank, 150 Mont. 422, 435 P.2d 878 and cases cited therein.
We consider that in the usual case good judicial administration requires freedom of action by the district court prior to trial and noninterference on our part at this stage.
In the absence of extraordinary and compelling circumstances beyond simply requiring a party to proceed to trial, we decline to review the order of the district court denying summary judgment by supervisory control or other extraordinary writ. It would assist counsel and this Court immeasurably if the district courts would indicate their reasons for denial of summary judgment in future cases.
