Mountain States Telephone & Telegraph Corp., supra; Primock v. Hamilton, 168 Colo. 524, 452 P.2d 375 (1969); Credit Investment & Loan Co. v. Guaranty Bank & Trust Co., 143 Colo. 393, 353 P.2d 1098 (1960). The action must proceed to trial if a genuine issue of material fact exists. The burden of establishing the lack of a triable issue, therefore, is upon the moving party, and all doubts must be resolved against him. Primock v. Hamilton, supra; O’Herron v. State Farm Mutual Auto Ins. Co., 156 Colo. 164, 397 P.2d 227 (1964).
The trial court relied upon the following portion of C.R.C.P. 56(e) in reaching its decision:
“When a motion for summary judgment is made and supported as provided in this Rule, an adverse party may not rest upon the mere allegations or denials of his pleading, but his response by affidavits or otherwise provided in this Rule, must set forth specific facts showing that there is a genuine issue for trial. If he does not respond, summary judgment, if appropriate, shall be entered against him.” (Emphasis added).
The trial court found that “no Affidavits or other response was provided by the Plaintiff in accordance with Rule 56,” and concluded that no' genuine issue of any material fact existed.
Once a movant makes a convincing showing that genuine issues are lacking, C.R.C.P. 56(e) requires that the opposing party adequately demonstrate by relevant and specific facts that a real controversy exists. Sullivan v. Davis, 172 Colo. 490, 474 P.2d 218 (1970). Supporting affidavits submitted by the moving party, however, may be insufficient to satisfy his burden. Adickes v. S.H. Kress & Co., 398 U.S. 144, 90 S.Ct. 1598, 26 L.Ed.2d 142 (1972); Benton-Volvo-Metairie, Inc. v. Volvo Southwest Inc., 479 F.2d 135 (5th Cir. 1973); see 6 J. Moore, Federal Practice ¶ 56.11 [3] (2d ed.). In Benton-Volvo-Metairie Inc. v. Volvo Southwest Inc., supra, the court said:
“[T]his court feels that in certain cases the filing of counter affidavits would be only a perfunctory task. Dawkins v. Green, 412 F.2d 644 (5th Cir. 1969) at 646. It is well established that on a motion for summary judgment, the moving party carries the burden of proof, and he must show that no genuine issue of material fact exists even though at trial his opponent had the burden of proving the facts alleged. Dawkins v. Green, supra; Doff v. Brunswick Corporation, 372 F.2d 801 (9 Cir. 1967). In the case before us now defendants moved for summary judgment and submitted affidavits to support such a motion; plaintiff filed no affidavits. If this was then an appropriate case for summary judgment the action could have been properly ended at that point. However, the affidavits filed by the defendant are simply a restatement of the denials and counter charges contained in their answer and they contained no new information. Moreover, they set forth only ultimate facts or conclusions in that their contents are statements . . . which in no way proved or disproved any of the
