"To separate the issues in a case so that
one issue or set of issues can be tried and resolved before the
others. For example, death penalty cases are always bifurcated. The
court or juryfirst hears the evidence of guilt and reaches a
verdict, and then hears evidence about and decides upon which
punishment to impose (death or life in prison without parole).
Bifurcated trials are also common in product liability class action
lawsuits in which many people claim that they were injured by the
same defective product -- the issue of liability is tried first,
followed by the question of damages. Bifurcation is authorized by
Rule 42(b) of the Federal Rules of Civil Procedure. "
