Why California’s "Pure" Comparative Negligence Rule Is More Favorable Than You Might Think

A lot of accident victims assume that if they were even partly responsible for what happened, they're out of luck. In California, that assumption is usually wrong — and understanding why starts with a 1975 California Supreme Court decision that changed the rules.

Before 1975: An All-or-Nothing Rule

California used to follow "contributory negligence," an old common-law rule under which ANY fault on the injured person's part — even 1% — completely barred recovery. This produced harsh, often unfair results: someone 95% not at fault for a crash could walk away with nothing because of a small mistake of their own.

Li v. Yellow Cab Co.: The Rule Changes

In Li v. Yellow Cab Co. (1975), the California Supreme Court replaced contributory negligence with "pure comparative negligence." Under this rule, an injured person can recover damages no matter how much they were at fault — their award is simply reduced by their own percentage of responsibility.

What "Pure" Means Here

Some states adopted comparative negligence too, but with a cutoff — commonly 50% or 51% — above which an injured person recovers nothing. California's version is "pure," meaning there's no cutoff at all. Even someone found 90% at fault can still recover the remaining 10% of their damages.

A Concrete Example

Say a jury awards $200,000 in damages but finds the injured person 40% at fault for the accident. Under California's rule, that person still recovers $120,000 — the $200,000 reduced by their 40% share of fault. In a cutoff-based state, a 40% fault finding might still allow recovery (if under that state's threshold), but a higher fault percentage could eliminate the claim entirely.

Why This Matters for How a Case Gets Evaluated

Because fault is a matter of degree rather than an all-or-nothing question, a case isn't automatically hopeless just because the other side raises comparative fault arguments. The real question becomes how the fault percentages shake out — which is exactly the kind of factual and legal analysis worth getting an experienced opinion on.

The Takeaway

If an insurance adjuster or the other side is arguing you were partly at fault for an accident, that's not the end of the conversation — under California law, it's a question of degree, not a bar to recovery.
