What is Bellwether Trial?

A representative trial selected from a group of similar cases in mass tort or multidistrict litigation that is tried first to help gauge the likely outcomes and settlement values of the remaining cases.

Understanding Bellwether Trial

Bellwether trials serve as test cases that provide both sides with valuable information about how juries will react to the evidence, what damages are likely, and what arguments are most effective. The results often drive global settlement negotiations. While bellwether verdicts are not binding on other cases in the litigation, they strongly influence the resolution of thousands of similar claims.
