Summary judgment under I.R.C.P. 56(c) is proper only when there is no genuine issue of material fact and the moving party is entitled to judgment as a matter of law. On appeal, we exercise free review in determining whether a genuine issue of material fact exists and whether the moving party is entitled to judgment as a matter of law. Edwards v. Conchemco, Inc., 111 Idaho 851, 852, 727 P.2d 1279, 1280 (Ct. App. 1986). When assessing a motion for summary judgment, all controverted facts are to be liberally construed in favor of the nonmoving party. Furthermore, the trial court must draw all reasonable inferences in favor of the party resisting the motion. G & M Farms v. Funk Irrigation Co., 119 Idaho 514, 517, 808 P.2d 851, 854 (1991); Sanders v. Kuna Joint School Dist., 125 Idaho 872, 874, 876 P.2d 154, 156 (Ct. App. 1994). The party moving for summary judgment initially carries the burden to establish there is no genuine issue of material fact and that he or she is entitled to judgment as a matter of law. Eliopulos v. Knox, 123 Idaho 400, 404, 848 P.2d 984, 988 (Ct. App. 1992). When the party moving for summary judgment will not carry the burden of production or proof at trial, the genuine issue of material fact burden may be met by establishing the absence of evidence on an element that the nonmoving party will be required to prove at trial. Dunnick v. Elder, 126 Idaho 308, 311, 882 P.2d 475, 478 (Ct. App. 1994). Such an absence of evidence may be established either by an affirmative showing with the moving party's own evidence or by a review of all the nonmoving party's evidence and the contention that such proof of an element is lacking. See id., at n.1, 882 P. 2d at 478 n.1. Once such an absence of evidence has been established, the burden then shifts to the party opposing the motion to show, via further depositions, discovery responses or affidavits, that there is indeed a genuine issue for trial or to offer a valid justification for the failure to do so under I.R.C.P. 56(f). Sanders, 125 Idaho at 874, 876 P.2d at 156. The United States Supreme Court, in interpreting Federal Rule of Civil Procedure 56(c), which is identical in all relevant aspects to I.R.C.P. 56(c), stated: In our view, the plain language of Rule 56(c) mandates the entry of summary judgment, after adequate time for discovery and upon motion, against a party who fails to make a showing sufficient to establish the existence of an element essential to that party's case, and on which that party will bear the burden of proof at trial. In such a situation, there can be "no genuine issue as to any material fact," since a complete failure of proof concerning an essential element of the nonmoving party's case necessarily renders all other facts immaterial. The moving party is "entitled to judgment as a matter of law" because the nonmoving party has failed to make a sufficient showing on an essential element of her case with respect to which she has the burden of proof. Celotex Corp. v. Catrett, 477 U.S. 317, 322-23, 91 L. Ed. 2d 265, 106 S. Ct. 2548 (1986) (citations omitted). the language and reasoning of Celotex has been adopted in Idaho. Dunnick, 126 Idaho at 312, 882 P.2d at 479.
