MCL 600.2959: Michigan’s 51% Bar, Damage Reductions, and Fault Allocation

Under Michigan’s 51% comparative fault rule, a court reduces your damages by your share of the fault, and if your fault is greater than the combined fault of everyone else involved, you lose the right to collect noneconomic damages like pain and suffering. The rule comes from MCL 600.2959 and applies in any civil action for personal injury, property damage, or wrongful death.¹

What “51%” Actually Means

The shorthand is useful but slightly misleading. The statute does not set a flat 50% line. It asks whether your fault percentage is greater than the aggregate fault of all other persons, including people who were never named as defendants.¹

In a straightforward two-party case, that works out to the familiar 51% rule. If you are 50% at fault, you can still recover noneconomic damages. If you are 51%, you cannot. In a case with multiple defendants and other contributing people, the math shifts. A plaintiff found 40% at fault clears the bar when the remaining 60% is split among several others, because the comparison is against their combined fault, not any one person’s share.

The rule reaches broadly. MCL 600.2959 applies to actions “based on tort or another legal theory,” and the companion statute MCL 600.6304 defines fault to include negligent acts and omissions, intentional conduct, breach of warranty, breach of legal duty, and conduct that could give rise to strict liability.² It is not limited to car crashes.

How Economic Damages Get Reduced

Economic damages are the losses you can document on paper: medical bills, rehabilitation costs, lost wages, repair or replacement of damaged property. These are always reduced by your fault percentage, no matter how high that percentage goes.¹

A jury that finds $80,000 in economic damages and assigns you 30% fault produces a $56,000 judgment on that portion. At 70% fault, the same $80,000 shrinks to $24,000. Even a plaintiff found 90% responsible still collects 10% of their proven economic losses. The reduction is mandatory and mechanical.

What Happens to Pain and Suffering

Noneconomic damages cover the intangible side of an injury: physical pain, emotional distress, disfigurement, and loss of enjoyment of life. These are treated in two very different ways depending on which side of the aggregate-fault line you fall on.

If your fault does not exceed the combined fault of everyone else, noneconomic damages survive and are simply reduced by your percentage, the same way economic damages are. A $100,000 pain and suffering award paired with 35% plaintiff fault produces a $65,000 recovery on that portion.

If your fault does exceed the combined fault of the others, noneconomic damages are gone. Completely. The jury may have awarded $500,000 for pain and suffering, but the judge strikes the entire amount from the judgment. You still receive your reduced economic damages, but every dollar tied to intangible harm disappears.¹

How the Fault Percentages Get Decided

The jury answers special interrogatories identifying two things: the total dollar amount of your damages, and the percentage of fault belonging to every person who contributed to the injury. In a bench trial, the judge makes those findings. The percentages have to add up to 100%.²

For each person, the jury weighs the nature of the conduct and how strongly that conduct caused the harm. Someone driving 10 miles over the limit and someone running a red light might both bear fault for the same collision, but the causal weight of running the red light will typically carry a higher percentage.

Fault Assigned to People Who Were Never Sued

This part surprises most plaintiffs. The jury can assign fault to people who are not parties to the lawsuit. MCL 600.2957 requires the trier of fact to “consider the fault of each person, regardless of whether the person is, or could have been, named as a party to the action.”³

When a defendant points to a nonparty, say a driver who left the scene or a manufacturer who was never joined, and the jury assigns that nonparty 20% of the fault, that 20% effectively vanishes from your recovery. Nobody pays the nonparty’s share. The allocation also feeds into the aggregate-fault calculation that decides whether your noneconomic damages survive at all.

Why Winning Isn’t the Same as Collecting

Michigan makes liability “several only and not joint.” Each defendant is responsible for their own percentage of the judgment and nothing more.²

Picture a jury that assigns 60% to Defendant A, 20% to Defendant B, and 20% to you. Defendant A owes 60% of the reduced judgment and Defendant B owes 20%. If Defendant B is uninsured and has no assets, you cannot force Defendant A to cover B’s share. You absorb that loss. Combined with nonparty fault allocation, Michigan’s system can meaningfully shrink what you actually take home, even in cases where your own share of fault is modest.

How a Reduced Award Is Taxed

Federal tax law treats damages for personal physical injuries or physical sickness as excluded from gross income under 26 U.S.C. § 104(a)(2). That exclusion covers both the economic and noneconomic parts of a physical injury award, whether paid through a verdict or a settlement.⁴

The exclusion does not reach emotional distress damages unconnected to a physical injury. Awards for claims like defamation or harassment are taxable, except for the portion that reimburses you for medical care, such as therapy costs, that you actually paid for the emotional harm. Punitive damages are taxable regardless of the underlying claim.⁴
