- Appeal:record-based review.
- Postconviction:off-record claims.
- Sentence:correct if illegal.
- Deadlines:tight — act fast.
A conviction isn't always the end. In Minnesota you may be able to challenge it after sentencing through a direct appeal, a postconviction petition, a motion to correct the sentence, or plea withdrawal — but each has strict deadlines, so acting quickly is essential. Which path fits depends on what went wrong and whether the problem appears in the trial record. Here's an overview of the options and the time limits that govern them.
Direct Appeal
A direct appeal asks a higher court to review the trial record for legal error — an improper suppression ruling, a bad jury instruction, insufficient evidence, or a sentencing mistake. The deadlines are short and strict: generally 90 days after sentencing for a felony or gross misdemeanor, and 30 days for a misdemeanor. An appeal reviews what's already in the record; it doesn't add new evidence.
Postconviction Relief
When the problem isn't visible in the trial record — like ineffective assistance of counsel or newly discovered evidence — the path is usually a postconviction petition under Chapter 590. It allows new facts to be developed and is generally subject to a two-year filing limit, with limited exceptions. It's the vehicle for problems that only become clear after the case is over.
Correcting an Illegal Sentence
If the sentence itself is unlawful — for example, based on a miscalculated criminal history score or exceeding what the law allows — there are mechanisms to ask the court to correct the sentence. A wrong sentence can sometimes be fixed even when the conviction itself stands.
Plea Withdrawal
If your conviction came from a guilty plea, you may in some circumstances move to withdraw the plea — for instance, to correct a manifest injustice, or where the plea wasn't accurate, voluntary, and intelligent. Plea withdrawal isn't automatic, and the standard is demanding, but it's an avenue where a plea was flawed.
Why Speed Matters
The single most important thing about all of these is the deadlines. Appellate windows are short and some can't be extended; the postconviction limit runs from the conviction or appellate decision. Missing a deadline can permanently foreclose an otherwise valid challenge. If you think something went wrong in your case, the time to evaluate it is now — not later.
Which Path Fits?
Choosing among these depends on what the problem is and where it shows up:
- Error in the trial record -> direct appeal.
- Problem outside the record (ineffective counsel, new evidence) -> postconviction.
- Unlawful sentence -> sentence correction.
- Flawed guilty plea -> plea withdrawal.
Sometimes more than one applies, and the right strategy considers all of them together.

Frequently Asked Questions
Can a conviction be overturned in Minnesota?
It can, in the right case — through a direct appeal, postconviction relief, sentence correction, or plea withdrawal, depending on what went wrong. Each has strict deadlines, so a prompt evaluation is essential.
What's the deadline to challenge my conviction?
It depends on the path: generally 90 days after sentencing for a felony or gross-misdemeanor appeal, 30 days for a misdemeanor, 60 days to appeal a postconviction denial, and a two-year limit for postconviction petitions. Confirm your specific deadline immediately.
What if the problem isn't in the trial record?
Issues like ineffective assistance of counsel or newly discovered evidence usually can't be shown from the record and are raised through a postconviction petition rather than a direct appeal.
Can I challenge just my sentence?
Yes. If the sentence is unlawful — for example, based on a miscalculated criminal history score — there are ways to ask the court to correct it, sometimes even when the conviction stands.
