Whether a court may grant summary judgment based on evidence introduced for the first time in a reply brief absent the non‑movant's filing of a motion to strike or request for surreply, thereby imposing a strict forfeiture rule in direct, irreconcilable conflict with Amada Family Ltd. Partnership v. Pomeroy.
The Panel held that Plaintiff forfeited all objections to Best Buy's reply‑only evidence by failing to file a motion to strike or request for surreply before the District Court entered summary judgment. Opinion at ¶ 34. This uncodified forfeiture rule does not merely lack foundation in Colorado law; it places this division in direct, diametric conflict with the division in Amada Family Ltd. Partnership v. Pomeroy, 2021 COA 73.
The baseline rule is that a movant cannot ambush a non‑movant with new arguments or evidence in a reply brief. As established in Wallman v. Kelley, 976 P.2d 330, 332 (Colo. App. 1999):
Critically, Wallman did not condition this protection on the non‑movant's preemptive filing of motions to strike or requests for surreply. This is because the protection is structural and cannot be cured retroactively through discretionary motions the non‑movant may or may not know to file; the C.R.C.P. 56 framework assumes movants will comply with Wallman from the outset. In other words, a non‑movant cannot "waive" a movant into satisfying its initial evidentiary threshold, because an unsupported opening motion demands denial even if the non‑movant stands completely silent. See People v. Hernandez & Assocs., Inc., 736 P.2d 1238 (Colo. App. 1986); see also Wolther v. Schaarschmidt, 738 P.2d 25 (Colo. App. 1986) (same).
"Although it may be perilous for the party opposing summary judgment not to file a responsive affidavit… election not to do so does not relieve the moving party of its burden to establish that summary judgment is appropriate."
Amada expressly forecloses this exact forfeiture trap. The Amada panel faced the identical procedural question presented here: whether a litigant forfeits an objection to a summary judgment reply brief ambush by failing to preserve it before the trial court. The Amada panel explicitly rejected forfeiture, holding:
"We disagree. [The non‑movants] had no opportunity to raise the issue because [the movant] did not make arguments… until it replied to the [non‑movants'] response to its motion for summary judgment. Although we normally do not consider unpreserved issues in civil cases… here, we elect to do so."
By holding that Plaintiff in this case did forfeit his objection by failing to file a motion to strike or request for surreply, the Panel issued a ruling in pure diametric conflict with Amada. A litigant cannot simultaneously be excused from objecting because they "had no opportunity" (Amada), yet strictly penalized for failing to create that very opportunity (the Panel). These two procedural rules are mutually exclusive. Trial courts cannot apply both regimes at once. To restore the uniform application of C.R.C.P. 56, this Court must resolve the split.
