comparative-fault

Apply US comparative-negligence rules to a damages award.

When more than one party is at fault, the plaintiff's recovery is reduced by their own share of responsibility. US states do this in four materially different ways:

Rule Effect
Pure comparative Reduce by fault share, no cut-off
Modified 50% bar Reduce, but barred at 50% or more
Modified 51% bar Reduce, but barred above 50%
Contributory Any fault bars recovery entirely

The two modified rules diverge at exactly a 50/50 split, which is a common settlement posture: under a 50% bar the plaintiff takes nothing, under a 51% bar they take half.

use comparative_fault::{net_recovery, Rule};

assert_eq!(net_recovery(100_000.0, 0.20, Rule::Pure), 80_000.0);
assert_eq!(net_recovery(100_000.0, 0.50, Rule::Modified50), 0.0);
assert_eq!(net_recovery(100_000.0, 0.50, Rule::Modified51), 50_000.0);
