Michigan Criminal Procedure: Arrest Through Sentencing

Michigan's criminal procedure framework governs every stage of the state's prosecution process, from the moment of arrest through the imposition of a sentence. The process is structured by the Michigan Court Rules (MCR), the Michigan Compiled Laws (MCL), and constitutional guarantees drawn from both the Michigan Constitution of 1963 and the United States Constitution. Understanding this framework is essential for attorneys, researchers, defendants, and policy professionals navigating Michigan's criminal courts, which processed more than 800,000 criminal case filings in a recent multi-year reporting cycle according to the State Court Administrative Office (SCAO).

Definition and scope

Michigan criminal procedure encompasses the legally mandated sequence of events by which the state investigates, charges, prosecutes, and sentences individuals accused of criminal offenses under state law. The procedural architecture is codified primarily in Chapters 760–777 of the Michigan Compiled Laws (MCL 760–777), which constitute the Michigan Code of Criminal Procedure. Supplementing these statutes are the Michigan Court Rules, particularly MCR 6.000 through MCR 6.610, which govern procedure in criminal cases before circuit courts, district courts, and the Michigan Court of Appeals.

Scope and coverage: This reference covers criminal procedure applicable in Michigan state courts — circuit courts handling felonies, district courts handling misdemeanors and preliminary examinations, and the appellate courts reviewing those proceedings. It does not address federal criminal procedure under the Federal Rules of Criminal Procedure, which govern prosecutions brought in the U.S. District Courts for the Eastern and Western Districts of Michigan. Tribal criminal jurisdiction — held independently by Michigan's 12 federally recognized tribes — falls outside this scope, as addressed in Michigan Tribal Law and Sovereignty. Juvenile delinquency proceedings, which follow a distinct procedural track under MCL 712A, are covered separately in Michigan Juvenile Justice System.

Core mechanics or structure

Arrest and Initial Detention

An arrest in Michigan may be made with or without a warrant, subject to constitutional constraints. A warrantless arrest requires probable cause under MCL 764.15, which enumerates circumstances permitting warrantless seizure, including commission of a felony in the officer's presence or reasonable cause to believe a felony has been committed. Following arrest, the defendant must be brought before a magistrate or district judge "without unnecessary delay" — Michigan courts have interpreted this consistent with McNabb-Mallory doctrine principles and MCL 764.26.

Arraignment

The initial arraignment, governed by MCR 6.104, must occur without unnecessary delay. At arraignment, the charge is formally read, constitutional rights are explained, and bail or pretrial release conditions are set. District courts conduct arraignments for all offenses; for felonies, this is a preliminary arraignment preceding further proceedings.

Preliminary Examination

For felony charges, MCL 766.1 through MCL 766.20 mandate a preliminary examination before a district court judge within 14 days of arraignment if the defendant is in custody, or within 21 days if released. The prosecution must establish probable cause that a crime was committed and that the defendant committed it. The defendant has the right to cross-examine witnesses and present evidence. If probable cause is found, the defendant is bound over to circuit court.

Information and Arraignment in Circuit Court

Following bindover, the prosecutor files a written information in circuit court under MCL 767.42. The defendant is then arraigned in circuit court under MCR 6.113, where a not guilty plea is typically entered and trial scheduling begins.

Pretrial Motions and Discovery

Michigan Court Rule 6.201 governs reciprocal discovery. The prosecution must disclose witness lists, police reports, and exculpatory material consistent with Brady v. Maryland, 373 U.S. 83 (1963). Pretrial motions may address suppression of evidence, challenges to charging instruments, venue, and competency.

Trial

Defendants charged with felonies carrying more than 6 months' imprisonment hold a Sixth Amendment right to jury trial, codified in Michigan Constitution Article I, § 20. Jury selection, opening statements, examination of witnesses, and closing arguments proceed under MCR 6.400 through 6.420. The prosecution bears the burden of proof beyond a reasonable doubt.

Sentencing

Upon conviction, sentencing in Michigan circuit courts is governed by the Michigan Sentencing Guidelines (MCL 769.31–769.36), a structured system producing a recommended minimum sentence range. Judges must score offense variables (OVs) and prior record variables (PRVs) to calculate a guidelines cell. Post-People v. Lockridge, 498 Mich. 358 (2015), the guidelines are advisory, but departure from them requires articulated, on-the-record reasons. The full structure of sentencing ranges is documented at Michigan Sentencing Guidelines.

Causal relationships or drivers

The structure of Michigan criminal procedure reflects three reinforcing pressures: constitutional mandate, legislative reform, and judicial interpretation.

Constitutional mandate operates at two levels. The Michigan Constitution of 1963, Article I, §§ 17–20, guarantees due process, protection against double jeopardy, the right to counsel, and jury trial. The Fourteenth Amendment to the U.S. Constitution applies federal constitutional guarantees to state proceedings through incorporation doctrine, imposing minimum procedural floors Michigan cannot fall below.

Legislative reform has produced substantial shifts in procedural design. The 1994 Truth in Sentencing Act altered parole eligibility for violent offenders. The Michigan Indigent Defense Commission Act of 2013 (MCL 780.981–780.1003) established the Michigan Indigent Defense Commission (MIDC) to address systemic deficiencies in public defense — a structural response to findings that pre-reform systems lacked minimum standards in 82 of Michigan's 83 counties.

Judicial interpretation shapes how statutory and constitutional provisions interact. People v. Lockridge rendered the sentencing guidelines advisory, fundamentally altering the balance between judicial discretion and legislative structure. People v. Dunbar, 423 Mich. 380 (1985), shaped standards for effective assistance of counsel in the plea context.

The Michigan Public Defender System page details how MIDC standards translate into provider obligations at the county level.

Classification boundaries

Michigan criminal offenses are categorized along two primary axes: offense type and severity class.

By type: Offenses are classified as felonies, high court misdemeanors, or misdemeanors. Felonies are prosecuted in circuit court; misdemeanors are resolved in district court. High court misdemeanors — punishable by up to 2 years under MCL 761.1(g) — are technically misdemeanors but follow felony procedure in circuit court.

By sentencing class: The sentencing guidelines divide felonies into nine classes (M2 through A), with Class A representing the most serious offenses such as first-degree murder. Each class carries a statutory maximum sentence ranging from 2 years (Class G/H) to life imprisonment (Class A). The guidelines grid for each class produces a minimum range based on OV and PRV scores.

By procedural track: Certain offenses trigger specialized procedures. Domestic violence cases activate mandatory arrest provisions under MCL 764.15a. Drug offenses may qualify for assignment to a drug treatment court under MCL 600.1060. Expungement eligibility follows a separate statutory track under MCL 769.4a and the Clean Slate Act amendments, detailed at Michigan Expungement Law.

Tradeoffs and tensions

Efficiency vs. due process: Plea bargaining resolves approximately 90–95% of Michigan criminal cases without trial, according to SCAO annual reports. This reduces court congestion but compresses the fact-finding process, creating pressure on defendants — particularly those detained pretrial — to accept plea offers regardless of factual innocence.

Advisory vs. mandatory guidelines: The Lockridge decision expanded judicial discretion at sentencing, which proponents argue allows individualized justice. Critics contend it reintroduces sentencing disparity that the structured guidelines were designed to eliminate. Appellate review of guideline departures under MCR 7.212 provides a corrective mechanism, but its scope is contested.

Public safety vs. pretrial liberty: Michigan's cash bail system, governed by MCL 765.1–765.28, conditions pretrial release on financial capacity in many cases. Reform advocates have argued before the Michigan Supreme Court and the legislature that wealth-based detention violates equal protection guarantees under Article I, § 2 of the Michigan Constitution of 1963.

Victim rights vs. defendant rights: Michigan's Crime Victim Rights Act (MCL 780.751 et seq.) and the Marsy's Law amendment to Article I, § 24 of the Michigan Constitution (adopted 2024) expand victim participation in plea and sentencing proceedings. Defense attorneys have raised concerns that expanded victim presence at pretrial hearings may prejudice neutrality in bail determinations.

Post-conviction rights and the parole process are covered at Michigan Parole and Probation Law.

Common misconceptions

Misconception: Arrest equals charge. An arrest does not constitute a criminal charge. The prosecutor independently decides whether to authorize charges under MCL 767.40a. Law enforcement makes arrests; prosecutors file informations or complaints. A significant proportion of arrests do not result in prosecution.

Misconception: Preliminary examination is mandatory. Under MCR 6.110(a), a defendant may waive the preliminary examination. Waiver is common in plea negotiations but forfeits the opportunity to test the prosecution's evidence at an early stage.

Misconception: Michigan sentencing guidelines are mandatory. Since People v. Lockridge, 498 Mich. 358 (2015), the guidelines are advisory. Judges may depart above or below the recommended minimum range with articulated substantial and compelling reasons, subject to appellate review.

Misconception: The right to a jury trial applies to all offenses. Misdemeanors punishable by 93 days or less do not carry a jury trial right under Michigan Constitution Article I, § 20 or the Sixth Amendment as interpreted in Blanton v. City of North Las Vegas, 489 U.S. 538 (1989). Trial in those cases is before a district court judge.

Misconception: Expungement follows automatically after sentencing. Expungement requires a separate petition process under MCL 780.621, subject to waiting periods, offense exclusions, and judicial discretion, as detailed at Michigan Expungement Law.
