Criminal Defense Law in Minnesota: Overview
Minnesota employs a unique four-degree system for DWI offenses and uses structured sentencing guidelines that assign severity levels and criminal history scores to determine appropriate sentences. The state legalized recreational marijuana in 2023 through legislative action. Minnesota does not have a traditional three-strikes law but uses sentencing guidelines that increase punishment based on criminal history. The state follows the duty to retreat doctrine in public but recognizes the castle doctrine for home defense. Minnesota abolished the death penalty in 1911 and has a robust expungement framework that was expanded significantly in 2015. The state classifies felonies by maximum sentence rather than a letter grade, with the sentencing guidelines grid providing presumptive sentences based on offense severity and prior record.

Four-Degree DWI System
Minnesota categorizes DWI offenses into four degrees based on aggravating factors rather than simply counting prior offenses. Fourth-degree DWI (misdemeanor) is a standard first offense with BAC under 0.16%. Third-degree DWI (gross misdemeanor) applies when there is one aggravating factor, such as a BAC of 0.16% or higher, a prior DWI within 10 years, or a child under 16 in the vehicle. Second-degree DWI (gross misdemeanor) involves two or more aggravating factors. First-degree DWI (felony) applies when the offender has three or more prior qualified DWI incidents within 10 years, a prior felony DWI conviction, or a prior conviction for criminal vehicular homicide. First-degree DWI carries up to 7 years in prison and a $14,000 fine. Minnesota also has an administrative process for license revocation that runs parallel to criminal proceedings.
Duty to Retreat and Authorized Use of Force
Minnesota follows the duty to retreat doctrine in public spaces. Under Minn. Stat. § 609.06, a person may use reasonable force to resist an offense against their person, but the use of deadly force is justified only when there is no reasonable possibility of retreat and the person reasonably believes deadly force is necessary to prevent great bodily harm or death. Inside the home, Minnesota recognizes the castle doctrine under Minn. Stat. § 609.065, which provides that a person may use deadly force against an intruder who is committing or attempting a felony within the dwelling. The homeowner must still have a reasonable belief that deadly force is necessary to prevent great bodily harm or death. Minnesota does not have a statutory stand your ground law, and multiple legislative attempts to enact one have been unsuccessful.
Marijuana Legalization and Expungement of Prior Offenses
Minnesota legalized recreational marijuana for adults 21 and over on August 1, 2023. Adults may possess up to 2 ounces of flower in public and up to 2 pounds at home. Home cultivation of up to 8 plants (4 mature) is permitted. The Office of Cannabis Management oversees licensing and regulation. As part of the legalization law, Minnesota provided an automatic expungement process for individuals with prior marijuana convictions for conduct that is no longer criminal. A resentencing provision allows individuals currently incarcerated for newly legal marijuana conduct to petition for release. Possession above legal limits remains criminal, with penalties increasing based on the amount possessed.
Minnesota Court System
Minnesota has a unified court system with three levels. The District Courts, organized into 10 judicial districts covering all 87 counties, handle all criminal matters including felonies, gross misdemeanors, misdemeanors, and petty misdemeanors. There is no separate court for lesser offenses. The Minnesota Court of Appeals has mandatory jurisdiction over most criminal appeals. The Minnesota Supreme Court has discretionary review over Court of Appeals decisions and mandatory jurisdiction in cases involving first-degree murder convictions and certain other matters. Juvenile delinquency cases are heard in the District Courts under the juvenile division.
Damages & Penalties
Minnesota classifies offenses as felonies (more than one year in prison), gross misdemeanors (up to one year in jail and $3,000 fine), misdemeanors (up to 90 days in jail and $1,000 fine), and petty misdemeanors (fine only, up to $300). The Minnesota Sentencing Guidelines Commission establishes a grid that determines presumptive sentences for felonies based on the offense severity level (I through XI) and the offender's criminal history score. Severity level XI (first-degree murder) carries a mandatory life sentence. For offenses at severity level VII and above, the presumptive sentence is commitment to prison. For severity levels I-VI, the presumptive sentence for offenders with low criminal history scores is a stayed (probationary) sentence. Judges may depart from guidelines with written reasons.
Recent Legislative Changes
Minnesota's 2023 marijuana legalization was a landmark change, making it the 23rd state to legalize recreational cannabis. The law includes significant social equity provisions, expungement of prior marijuana offenses, and a new regulatory structure under the Office of Cannabis Management. In 2023, the legislature also passed additional criminal justice reforms including expanded expungement eligibility and reduced penalties for certain low-level offenses. Minnesota has continued to invest in specialty courts including drug courts, DWI courts, and mental health courts as alternatives to traditional prosecution.

Frequently Asked Questions
What is the difference between the four degrees of DWI in Minnesota?
The degrees are based on aggravating factors. Fourth degree (misdemeanor) is a standard first DWI. Third degree (gross misdemeanor) applies with one aggravating factor such as a BAC of 0.16%+, a prior DWI within 10 years, or a child passenger under 16. Second degree (gross misdemeanor) involves two or more aggravating factors. First degree (felony) requires three prior qualified incidents within 10 years or a prior felony DWI.
Can I grow marijuana at home in Minnesota?
Yes. Under the 2023 legalization law, adults 21 and older may cultivate up to 8 marijuana plants at home, with no more than 4 being mature flowering plants. Plants must be in an enclosed, locked space not visible to the public. Local jurisdictions cannot prohibit home cultivation, though reasonable regulations on outdoor growing may apply.
How does expungement work in Minnesota?
Minnesota allows judicial expungement under Minn. Stat. § 609A.02. For cases not resulting in conviction (dismissed, acquitted), you can petition immediately. For petty misdemeanors and misdemeanors, the waiting period is 2 years after discharge. For gross misdemeanors, it is 4 years, and for most felonies, 5 years. The court balances the individual's need for expungement against public safety and the public's right to access criminal records.
Is Minnesota a stand your ground state?
No. Minnesota follows the duty to retreat doctrine. In public spaces, you must attempt to safely retreat before using deadly force in self-defense. The castle doctrine applies inside your home, where you may use deadly force against a person committing or attempting a felony without a duty to retreat, provided you reasonably believe deadly force is necessary to prevent great bodily harm or death.
What happens if I refuse a breathalyzer test in Minnesota?
Refusing a breathalyzer or blood test in Minnesota is a crime in itself. Test refusal is charged as a gross misdemeanor for a first offense, carrying up to one year in jail and a $3,000 fine, and results in automatic license revocation for one year. If there are aggravating factors, test refusal can be charged as a felony. The U.S. Supreme Court ruled in Birchfield v. North Dakota (2016) that states may criminalize breath test refusal but not warrantless blood test refusal.
How do Minnesota sentencing guidelines work?
The Minnesota Sentencing Guidelines use a grid with offense severity levels (I-XI) on one axis and criminal history scores (0-6+) on the other. Each cell contains a presumptive sentence. For severity levels VII and above, the presumptive sentence is prison commitment. For lower levels with low criminal history, the presumptive sentence is probation. Judges may depart from the guidelines upward or downward but must provide written reasons.
