Petition for Writ of Certiorari

A summary‑judgment trap
Colorado courts never sanctioned.

Upending the bedrock principle that a movant for summary judgment must come forward with evidence—not bare argument—the Court of Appeals' decision below quietly inverts C.R.C.P. 56, splits in pure diametric conflict with Amada, contravenes Wallman, Morlan, Central Bank, and Suncor, and forges procedural forfeitures that no Colorado authority requires. The result is a judicially sanctioned playbook for sandbagging that will be deployed against every pro se litigant and resource‑starved party in the State.

Every assertion traces directly to a docketed primary source. Every PDF is downloadable, body camera footage is on file, and the full record is browsable here. The record is the case.

C.A.R. 53(g)  :  Leave of Court  ·  7-Day Window

until 11:59 p.m. MDT on Thursday, June 4, 2026 — the seventh day after the petition's filing

The petition was filed on Thursday, May 28, 2026. Under C.A.R. 53(g), an amicus curiae may file a brief "only by leave of court or at the court's request," and it "must be filed within 7 days after the filing of the petition, opposition, or cross-petition that the amicus brief supports." The motion for leave (with the proposed brief attached) must therefore be filed after the petition's filing, but within 7 days of it — the countdown above runs to the close of that 7-day window.

Questions Presented

Four questions of statewide procedural law.

Each issue, standing alone, warrants this Court's supervisory correction under C.A.R. 49(b), (c), and (d). Together, they describe a decision that—left uncorrected—will systematically disadvantage unrepresented and resource‑limited parties in every Colorado civil court.

§
Petition Section II · Prejudice (Non‑Harmless Error)

The procedural deviations were outcome‑determinative.

Even if the reply‑only exhibits were considered, the late evidence is so internally irreconcilable and blatantly contradicted by the record that it cannot support summary judgment as a matter of law. Five factual sub‑rulings show prejudice: an affidavit–receipt contradiction; improperly admitted hearsay; an inverted foundation burden; an improper cardholder‑equals‑purchaser inference; and sworn testimony plus video footage dismissed as "self‑serving speculation."

Controlling Authorities

The Five Conflicts.

Five decisions the Petition asks the Supreme Court to restore — one a pure diametric conflict, three controlling Colorado rules the Panel contravened, and the federal standard the Panel disregarded when adopting irreconcilable evidence as simultaneously true.

Why This Matters · Now

A pro se petitioner facing irreparable harm.

$36,124.50
Attorney fees award threatened against the Petitioner if certiorari is denied (Colo. Ct. App. No. 2025CA1351).
12 min
Detention by store employees, captured on the Petitioner's own body camera. No merchandise was ever identified.

Police calls placed by Best Buy in connection with the detention, despite repeated employee claims to the contrary—a fact not even disputed by Defendant during the MSJ briefing.

3 cases
Already collateral‑damaged by the decision below: Case No. 2024CV242 (Appeal No. 2025CA2317) was dismissed because of the judgment in this case; the Petitioner's IFP status was revoked in Case No. 2024CV132—requiring payment of filing fees despite severe hardship; and now, in Case No. 2024CV241, defense counsel has filed a Motion to Dismiss openly asserting: “the Colorado Supreme Court has refused to take up any of his claims.” The Panel's unpublished opinion is already being weaponized to restrict Plaintiff's access to the courts in unrelated matters.

If the decision below stands, well‑resourced defendants will adopt this playbook for a judicially sanctioned ambush. The Petitioner will lose his home of last resort. And every future pro se Colorado plaintiff will face the same procedural ambush.

Why This Matters

Procedural fairness and civil
rights—in a single record.

This case is not a one‑off. The procedural distortions below were applied to a 12-minute false detention captured on body camera. The legal questions are independent from those facts—but the facts are why the questions reached this Court.

For Procedural & Appellate Practice

Summary judgment is the most frequently filed dispositive motion in Colorado civil courts. The Court of Appeals has quietly rewritten how it works: a movant may file an evidence‑free opening brief, observe the response, and produce its actual evidence only in reply—labeling that evidence "rebuttal" while arguing forfeiture to any later objection. If left uncorrected, these rules will alter how every Colorado MSJ is litigated.

The decision splits in pure diametric conflict with Amada, and conflicts with Wallman, Morlan, Central Bank, and Suncor—five decisions the Colorado Supreme Court and the Court of Appeals have repeatedly applied for decades.

For Civil Rights & Access to Justice

Mr. Montgomery was detained for twelve minutes by store employees who never identified what he supposedly possessed, who claimed to have called police that no record shows were ever called, and whose own affidavit and receipt—both introduced for the first time in reply—contradict each other on whether he was inside the store at all.

The Panel resolved every contradiction in Best Buy's favor while dismissing sworn testimony and body camera footage as merely "self‑serving speculation." That is not summary judgment—that is trial by appellate brief.

The One‑Minute Contradiction

A timeline that cannot be reconciled.

Defendant's two pieces of reply‑only evidence contradict each other—and both contradict Plaintiff's own body camera footage. The Court of Appeals never addressed this.

2:19 PM
Body Camera
Plaintiff is standing outside the store.
The detention has already begun.
2:20 PM
Receipt Timestamp
Plaintiff's brother—an authorized user—makes
a purchase using Plaintiff's credit card.
Manager's Affidavit
"Immediately Left"
Claims he watched Plaintiff steal and
"immediately leave the Best Buy Store."

If the manager observed Plaintiff steal and "immediately leave," there was no time for a purchase. If Plaintiff made a purchase and "immediately left," the theft observation is impossible. Both cannot be true—yet the Court of Appeals concurrently adopted both.

A Question to Pause On

Reviewing the prior‑litigation footnote in the Court of Appeals' opinion?

The Record documents, in granular detail, why every fact element of the prior Walmart cases is structurally absent from this Best Buy case, and gathers — with deep links into the live consolidated briefing PDFs — every passage in which Plaintiff has directly refuted the “lawsuit scammer” framing on the record.

Mr. Montgomery is a pro se petitioner, not an institutional movant. Whatever resources you can bring to bear—a name on the brief, a voice in the legal community, an institutional banner—materially advances the question whether a Colorado court of last resort permits the procedural ambush below.
