A motion to compel asks the court to order the prosecution to turn over evidence it is required to disclose but hasn't. In Minnesota felony and gross-misdemeanor cases, the State's disclosure duties under Rule 9 are broad — police reports, witness statements, test results, recordings, and more — and when the prosecution falls short, the defense can ask the court to compel production and, in serious cases, impose sanctions. It works hand in hand with the constitutional Brady/Giglio duty and is part of ordinary criminal discovery.
What the State Must Disclose
Under Minn. R. Crim. P. 9, in felony and gross-misdemeanor cases the prosecution must disclose a wide range of material without the defense even having to ask — including the names and statements of witnesses, the defendant's own statements, documents and tangible objects, examination and test results, and the evidence it intends to use at trial. The defense has reciprocal obligations. The goal is to avoid trial by ambush.
When You Need to Compel
Sometimes disclosure is incomplete or late — a missing squad video, an unproduced lab report, witness statements that never arrived. A motion to compel asks the court to order the State to produce what the rules require. It can also be used to seek items that require a court order, or to resolve a dispute about whether something must be disclosed.
Sanctions for Violations
When the State fails to comply, the court has options under the rules. Depending on the violation and the prejudice it caused, the court may order disclosure and grant a continuance, exclude the undisclosed evidence or witness, or impose other appropriate relief. The remedy is meant to fit the harm — and a serious, prejudicial discovery violation can meaningfully shift a case.
Why It Matters
You can't challenge evidence you've never seen. Full discovery is the foundation for every other pretrial motion — you often can't know whether to file a suppression motion, a probable-cause challenge, or an expert challenge until you have the complete file. Enforcing the State's disclosure duty is what makes the rest of the defense possible.

It's a request asking the court to order the prosecution to turn over evidence it's required to disclose under Rule 9 but hasn't produced — for example, missing reports, recordings, or test results.
What does the prosecution have to disclose in Minnesota?
In felony and gross-misdemeanor cases, Rule 9 requires broad disclosure without a request — witness names and statements, the defendant's statements, documents and objects, test results, and the evidence the State intends to use at trial. The defense has reciprocal duties.
What happens if the State doesn't comply?
The court can order disclosure and grant a continuance, exclude the undisclosed evidence or witness, or impose other appropriate relief depending on the violation and the prejudice it caused.
