Michigan charges unlawful imprisonment as a 15-year felony under MCL 750.349b, and which defense wins depends entirely on which element of that statute the prosecutor can't prove. This guide ranks the defense strategies used most often in Wayne, Oakland, Macomb, Washtenaw, and Monroe County courts and tells you when each one applies.
- Challenging the knowing-restraint element is the strongest unlawful imprisonment charge Michigan defense in most contested cases.
- Consent-based defenses work best in domestic and relationship disputes where the restraint was mutual or invited.
- MCL 750.349b carries up to 15 years — the police report determines which defense actually fits the facts.
- A procedural challenge to an illegal stop or coerced statement can suppress the evidence the whole case rests on.
- Kevin Bessant has handled restraint and confinement felonies in Detroit-area courts for over 20 years.
Why this matters
Unlawful imprisonment under MCL 750.349b isn't a garden-variety misdemeanor. It's a felony that requires proof the defendant knowingly restrained another person AND that one of four aggravating factors applied: a weapon was involved, the restraint was for ransom or reward, the victim suffered physical injury, or the victim was hidden from discovery through fraud or deceit. Miss one of those four and the case often collapses into a lesser charge before trial.
That structure is exactly why the right defense strategy matters more than in most felony cases — the statute hands the defense a built-in checklist of things the prosecution has to prove. Kevin Bessant Law reviews the police report and charging document first, because the aggravating factor listed on the complaint usually points straight to the weakest part of the state's case.
Say nothing to police beyond your name if you're arrested on this charge in 2026. Anything said in the squad car or at the station gets used to fill gaps in the restraint or intent element — the two things a defense attorney will be attacking first.
What makes a strong unlawful imprisonment defense
- Directly attacks an element the prosecution must prove beyond a reasonable doubt
- Matches the specific facts already in the police report and witness statements
- Can survive a preliminary examination challenge before the case reaches trial
- Doesn't force the defendant to testify or open the door to a prior record
- Backed by texts, video, 911 calls, or a third-party witness — not just the defendant's word
- Realistic given the specific aggravating factor charged (weapon, ransom, injury, concealment)
Defense strategies at a glance
| Defense strategy | Best for | Key requirement | Limitation |
|---|---|---|---|
| Challenging knowing/intentional restraint | Ambiguous physical-contact cases | No clear evidence of planning or intent | Fails if texts or recordings show premeditation |
| Consent or mutual restraint | Domestic and relationship disputes | Alleged victim's own prior statements | Weak if the alleged victim reverses the claim at trial |
| Self-defense or defense of others | Restraint that stopped an assault in progress | A reasonable belief of imminent harm | Defense carries the burden to raise it first |
| Alibi or mistaken identity | No direct witness ID, video or cell gaps | Verifiable location evidence for the time in question | Falls apart if defendant and victim already knew each other |
| Constitutional or procedural challenge | Illegal stop, coerced statement, Miranda violation | A motion to suppress filed before trial | Removes tainted evidence — doesn't dismiss the whole case |
1. Challenging knowing/intentional restraint: best defense for ambiguous physical-contact cases
MCL 750.349b requires the prosecution prove the restraint was knowing — an accident, a misunderstanding, or a momentary grab during an argument doesn't meet that bar on its own. This defense goes after the intent element directly, arguing the contact happened but the knowing restraint the statute demands never did.
Challenging knowing/intentional restraint pros:
- Attacks an element the prosecution must prove, not just a fact pattern
- Works even when the physical contact itself is not in dispute
- Doesn't require the defendant to take the stand
Challenging knowing/intentional restraint cons:
- Falls apart fast if texts, recordings, or planning evidence exist
- Requires a detailed read of the police report to find the gap
Best for: cases where contact happened but intent to confine is unclear. Verdict: Pursue.
2. Consent or mutual restraint: best defense for domestic and relationship disputes
A large share of unlawful imprisonment charges out of Wayne and Oakland County start as domestic arguments where one party later claims restraint. When the alleged victim's own prior statements, texts, or conduct suggest the situation was mutual rather than forced, that undercuts the restraint element itself.
Consent or mutual restraint pros:
- Strong when prior statements or messages support the defense
- Can be raised without the defendant testifying
- Common in domestic-dispute fact patterns Michigan courts see often
Consent or mutual restraint cons:
- Weakens if the alleged victim changes their account at trial
- Requires early documentation before memories or statements shift
Best for: domestic and relationship-based charges. Verdict: Pursue with corroboration.
3. Self-defense or defense of others: best defense when restraint stopped a threat
If the restraint occurred because the defendant was stopping an assault, protecting a child, or responding to an immediate physical threat, Michigan law allows a self-defense or defense-of-others argument even in restraint cases. This one requires showing the belief of danger was reasonable given the circumstances.
Self-defense or defense of others pros:
- Recognized defense under Michigan law, not a technicality
- Effective when 911 calls or witness accounts show a prior threat
- Can justify restraint that would otherwise look intentional
Self-defense or defense of others cons:
- The defense typically has to raise it first, shifting the narrative burden
- Doesn't help if the restraint outlasted the actual threat
Best for: cases where restraint interrupted an assault. Verdict: Pursue with documentation.
4. Alibi or mistaken identity: best defense for no-witness-ID cases
Some unlawful imprisonment charges rest on a 911 caller's description or a single eyewitness who didn't clearly see the defendant. Cell tower data, surveillance video, or a verified location at the time of the alleged incident can eliminate the defendant as the person involved entirely.
Alibi or mistaken identity pros:
- Can end a case outright rather than reducing the charge
- Strong when supported by video, receipts, or cell data
- Doesn't depend on interpreting the statute's elements at all
Alibi or mistaken identity cons:
- Useless if the defendant and alleged victim already knew each other
- Requires fast evidence-gathering before video is deleted or overwritten
Best for: stranger-on-stranger allegations with weak identification. Verdict: Pursue if evidence exists.
5. Constitutional or procedural challenge: best defense for police-error cases
When the arrest followed an illegal stop, a search without a warrant, or a statement taken without proper Miranda warnings, a motion to suppress can strip the prosecution of the evidence the entire charge depends on. This doesn't always end the case, but it often forces a plea to a lesser offense or a dismissal.
Constitutional or procedural challenge pros:
- Can remove the confession or physical evidence the case relies on
- Doesn't require disputing what actually happened during the incident
- Strong track record when body-cam or dashcam footage shows the violation
Constitutional or procedural challenge cons:
- Only removes the tainted evidence, not necessarily the whole case
- Requires a hearing and a judge willing to suppress
Best for: arrests built on a bad stop, search, or interrogation. Verdict: Pursue aggressively.
How these defenses get evaluated
Every one of these five strategies gets weighed against the same checklist: does it attack a real element of MCL 750.349b, does it match the police report, can it survive a preliminary exam, and does it avoid putting the defendant on the stand unnecessarily. A defense that sounds good in theory but contradicts the timeline in the charging document gets dropped fast — courts in Wayne, Oakland, and Macomb County see through mismatched narratives quickly.
This is also why a free case evaluation matters before deciding on a strategy. Kevin Bessant has spent over 20 years trying felony cases in metro Detroit courts and holds Michigan Super Lawyers recognition — that local court experience is what separates a defense that survives a prelim from one that gets shredded on cross.
Which defense should you use?
For most contested unlawful imprisonment charges, start by challenging the knowing-restraint element — it forces the prosecution to prove intent, and it works even when the underlying contact isn't disputed. If the case grew out of a domestic dispute, pair that with a consent-based argument backed by prior texts or statements. If the arrest itself involved an illegal stop or a coerced statement, the constitutional challenge should run alongside whatever substantive defense fits the facts, since suppressing evidence weakens the state's case no matter which defense you're building.

FAQ
What is unlawful imprisonment under Michigan law?
Unlawful imprisonment under MCL 750.349b is a felony that requires knowing restraint of another person combined with one of four aggravating factors: a weapon, ransom, physical injury, or concealment through fraud. It carries up to 15 years in prison in 2026.
What defenses work best against a Michigan unlawful imprisonment charge?
The strongest defense depends on the facts: challenging the knowing-restraint element works for ambiguous contact cases, consent defenses fit domestic disputes, and procedural challenges apply when the arrest followed an illegal stop or coerced statement.
Is unlawful imprisonment a felony in Michigan?
Yes. MCL 750.349b makes it a felony punishable by up to 15 years in prison, distinct from a simple assault or disorderly conduct charge.
Can unlawful imprisonment charges be dismissed before trial?
Yes, through a preliminary examination challenge if the prosecution can’t establish probable cause, or through a motion to suppress if police violated constitutional rights during the arrest.
Does unlawful imprisonment require physical restraint, or does a threat count?
The statute covers restraint accomplished by force, threat, or fraud, so a credible threat that prevents someone from leaving can satisfy the restraint element even without physical contact.
What should I do immediately after an unlawful imprisonment arrest in Michigan?
Say nothing to police beyond identifying information and call a criminal defense attorney immediately. Statements made before counsel is involved routinely fill gaps in the restraint or intent element.
How is unlawful imprisonment different from kidnapping in Michigan?
Kidnapping under MCL 750.349 typically involves moving the victim or holding them for ransom, while unlawful imprisonment under MCL 750.349b covers restraint with one of four specific aggravating factors, without requiring the victim be moved.
Does a domestic argument automatically become unlawful imprisonment in Michigan?
No. The prosecution still has to prove knowing restraint plus an aggravating factor. Many domestic-dispute charges get challenged successfully with a consent-based or lack-of-intent defense.
Does restraint have to involve physical force to count as unlawful imprisonment?
No. People v Railer, 288 Mich App 213 (2010), confirms that restraint under MCL 750.349b doesn’t require physical force or a specific duration, so non-physical restraint can still support a conviction.
When does self-defense actually work against an unlawful imprisonment charge?
People v Bosca, 310 Mich App 1 (2015), held that a self-defense or lawful-authority argument only succeeds when the facts actually implicate a recognized legal right to detain, not merely a belief that the restraint was justified.
One last thing
MCL 750.349b requires one of exactly four aggravating factors to sustain a felony charge — weapon, ransom, injury, or concealment. When the police report doesn't clearly establish one of those four, that's often the fastest route to a reduced charge at the pretrial stage, and it's the first thing worth checking before building any other defense.
Legal Authority: Statute and Case Law
Michigan’s unlawful imprisonment statute is codified at MCL 750.349b. Key published decisions include:
- People v Railer, 288 Mich App 213; 792 NW2d 776 (2010) — the Michigan Court of Appeals reviewed an insufficient-evidence challenge to an unlawful imprisonment conviction, confirming that restraint does not require physical force or any particular duration to satisfy the statute.
- People v Bosca, 310 Mich App 1; 871 NW2d 307 (2015) — addressed a defendant’s claim that his restraint of the alleged victims was lawful self-defense and defense of property; the court held those defenses only apply when the facts actually implicate a recognized legal right to detain, not merely a belief that force was justified.
- People v Chelmicki, 305 Mich App 58, 67-68; 850 NW2d 612 (2014) — confirms that MCL 750.349b provides alternative theories (weapon, felony-facilitation, etc.) under which a defendant can be convicted, so a jury need not agree on which specific aggravating factor applied.
