Criminal Appeals in Utah: The Basics

Short answer: A Utah criminal appeal generally must begin with a Notice of Appeal filed within 30 days of the judgment (district court) or 28 days (justice court) — and this deadline is jurisdictional, meaning the Court of Appeals loses the legal power to hear the case if it's missed, regardless of how strong the underlying legal argument is.

Who this guide is for

Anyone convicted in a Utah criminal case considering an appeal, or trying to understand the process before a deadline passes.

Why "jurisdictional" is the most important word here

Many legal deadlines have some flexibility — courts can sometimes excuse a late filing for good cause. A jurisdictional deadline is different: if you miss it, the appellate court generally cannot hear the case at all, no matter how compelling the reason for the delay or how strong the appeal would have been. This is exactly why acting immediately after a conviction — not waiting to decide whether to appeal — matters so much.

The two different deadlines

• District court criminal cases: Notice of Appeal generally due within 30 days of the judgment.
• Justice court criminal cases: Notice of Appeal generally due within 28 days of the order or judgment.

These are different numbers for a reason worth remembering — don't assume the same 30-day window applies if your case was in justice court.

What has to happen after filing the Notice of Appeal

Filing the notice itself isn't the end of the process — it starts a series of follow-on deadlines:

• Within 14 days of filing the notice, you generally need to either order transcripts or file a certificate stating none are needed.
• Within 21 days of filing the notice, you generally need to file a docketing statement with the appellate court clerk and serve it on all parties.

Missing these follow-on deadlines, while perhaps less catastrophic than missing the jurisdictional 30/28-day deadline, can still create real problems for how the appeal proceeds.

What an appeal actually reviews

A criminal appeal generally reviews the trial court's proceedings for legal error — it is not a new trial, and it's not an opportunity to introduce new evidence that wasn't part of the original case. The appellate court is reviewing whether the law was correctly applied, not re-deciding the facts from scratch.

Why you need an attorney for this, more than almost anything else on this site

Appellate practice involves specialized legal skills — identifying genuine legal error, preserving issues properly, and writing to an appellate standard — that are meaningfully different from trial-level criminal defense. Combined with the unforgiving jurisdictional deadline, this is squarely a situation where getting an attorney (including a public defender if you qualify — see Public Defender Eligibility in Utah) involved immediately after conviction matters enormously.

Frequently asked questions

Can the 30-day (or 28-day) appeal deadline ever be extended? Given its jurisdictional nature, this deadline is generally not something to count on being extended — treat it as an absolute, non-negotiable limit rather than assuming flexibility exists.

What if I want to appeal but can't afford an attorney? The same public defender eligibility framework that applies at trial generally extends to appeals for those who qualify — raise this immediately, given the tight deadline.

Does filing an appeal stop my sentence from being carried out? Not automatically — whether a sentence is stayed pending appeal is a separate legal question with its own process, not an automatic consequence of simply filing a notice of appeal.
