The Burden of Proof on a Motion for Summary Judgment in Utah

Understanding who must prove what — and when — is the key to winning or surviving a motion for summary judgment. Many litigants assume that whoever files the motion carries the full burden of proving their case. That is not how it works. Summary judgment in Utah operates through a shifting burden structure that differs meaningfully from the burden at trial — and misunderstanding it is one of the most common reasons well-founded motions fail and well-funded oppositions succeed.

This post explains the full burden framework under Utah Rule of Civil Procedure 56, how it shifts, what satisfies each stage, and what the appellate court does when the trial court gets it wrong.

The Moving Party Bears the Initial Burden

Under URCP Rule 56, the party moving for summary judgment carries the initial burden of production. The movant must first establish, through the record, that summary judgment is appropriate. But there are two distinct ways to meet this burden — and choosing the right approach is a strategic decision.

Path 1: Affirmative Evidence Negating an Essential Element

The movant can present affirmative evidence demonstrating that an essential element of the opposing party’s claim or defense does not exist. In a negligence case, for example, a defendant might submit evidence conclusively showing it owed no duty to the plaintiff. If the movant succeeds on this path, it has gone on offense — affirmatively disproving part of the opposing party’s case.

This path requires actual evidence: affidavits based on personal knowledge, deposition excerpts, documentary exhibits, or expert opinions. A movant cannot simply argue that the opposing party’s claim is weak — it must produce record evidence establishing the deficiency.

Path 2: Demonstrating an Absence of Evidence

Alternatively, the movant can demonstrate that the opposing party simply lacks sufficient evidence to establish an essential element at trial. This is sometimes called a “no-evidence” approach, and it does not require the movant to produce affirmative evidence of anything. Instead, the movant surveys the discovery record and points to what is not there — the missing witnesses, the absent documents, the unexplored causation theory — and argues the other side cannot make it to a verdict.

This path is often more efficient, particularly when discovery is substantially complete. A movant who reviews the full record and finds nothing supporting a key element — causation in a tort case, damages in a contract case — can point to that absence and shift the burden to the plaintiff.

KEY RULE

Two Ways to Meet the Initial Burden Under URCP Rule 56

(1) Produce affirmative evidence negating an essential element of the opposing party’s claim, OR (2) Demonstrate that the opposing party lacks sufficient evidence to establish an essential element at trial.

The movant does not need to do both. Either approach, if established, shifts the burden to the non-moving party.

How the Burden Shifts to the Non-Moving Party

Once the movant satisfies its initial burden through either path, the burden shifts to the non-moving party to come forward with specific facts showing a genuine dispute exists. This is where many summary judgment oppositions collapse.

The non-moving party cannot rest on the allegations in its complaint or answer. Pleadings are not evidence. The non-moving party must produce actual record evidence — deposition testimony, affidavits based on personal knowledge, documentary exhibits, or other admissible material — that demonstrates a triable issue of fact.

Utah courts have been clear: the non-moving party’s evidence must be more than a scintilla. It must be substantial enough that a reasonable jury could return a verdict in the non-moving party’s favor. Evidence that is merely colorable or not significantly probative is insufficient.

What Cannot Satisfy the Non-Moving Party’s Burden

Understanding what does not count is as important as knowing what does. Utah courts consistently hold that the following are insufficient to defeat summary judgment:

• Conclusory allegations in pleadings or briefs
• Affidavits not based on personal knowledge
• Affidavits that merely restate complaint allegations in affidavit form
• Speculation or conjecture about what evidence might show
• Promises that evidence will emerge at trial but has not been produced
• Metaphysical doubt or implausible inferences

If your opposition relies on any of these, the motion will likely be granted. The burden at the summary judgment stage is real, and Utah courts take it seriously.

The Burden Is Not the Same as the Trial Burden

The summary judgment burden of production is distinct from the ultimate burden of persuasion at trial. The non-moving party does not have to prove its case at the summary judgment stage — it only has to show that a genuine dispute of material fact exists. The threshold is lower than what the jury will ultimately require.

But it is not zero. Courts sometimes confuse these standards in both directions: granting summary judgment when the non-moving party has produced enough to create a triable issue, or denying it when the non-moving party’s opposition amounts to nothing more than speculation. When the trial court makes this error, de novo review on appeal gives the aggrieved party a genuine chance at correction. For how that appellate correction works, see our post on appealing a summary judgment ruling in Utah.

The Court’s Role: No Weighing, No Credibility Determinations

The court’s function at summary judgment is not to resolve factual disputes — it is to identify whether they exist. Courts do not weigh the relative strength of competing evidence, assess which witness is more credible, or predict what a jury would do. Those functions belong to the jury.

This limitation has a critical appellate implication: if the trial court resolved a factual dispute — chose to believe one side’s evidence over the other’s — that is reversible error. The Utah Court of Appeals reviewing the same record de novo can identify that the trial court stepped outside its summary judgment role and reverse accordingly. The de novo standard means neither the trial court’s reasoning nor its implicit credibility assessments bind the appellate court.

The Interaction Between Burden and the Statement of Undisputed Facts

In practice, the burden framework plays out primarily through the exchange of statements of undisputed material facts (SUMFs). The movant’s SUMF establishes — fact by fact, with pinpoint citations — the factual foundation for its legal argument. The non-moving party’s response must admit, dispute, or partially dispute each fact, with record citations for every dispute.

Any fact in the movant’s SUMF that the non-moving party fails to specifically dispute with record evidence is deemed admitted by most Utah district courts. This creates a powerful dynamic: a movant whose SUMF is accurate, specific, and well-cited can sometimes establish its entire factual case before the non-moving party even gets to the legal argument.

For a detailed treatment of how to build and respond to a SUMF, see our post on what is a statement of undisputed material facts.

KEY RULE

URCP Rule 56 — The Shifting Burden Framework

The moving party bears the initial burden — either producing evidence negating an essential element or showing the opposing party lacks evidence to prove one. Once met, the burden shifts to the non-moving party to produce specific, admissible record evidence creating a genuine dispute. Pleadings, speculation, and conclusory allegations do not satisfy this burden. The court does not weigh evidence or assess credibility — it only determines whether genuine disputes of material fact exist. When the trial court misapplies this framework, the Utah Court of Appeals corrects it de novo.

If Summary Judgment Has Been Filed Against You

The day you receive the motion is the day the clock starts. You typically have 28 days to oppose under URCP Rule 7, though your assigned judge’s standing order may modify that timeline. Lotus Appellate Law works with Utah litigants and trial counsel on both filing and opposing summary judgment motions, and on the appeals that follow. Contact us to discuss your options.
