Bellwether Trial

A bellwether trial is one of a small number of test cases tried first in a large group of similar lawsuits. The results help both sides judge how juries view the evidence and often guide settlement of the remaining cases, though they do not decide anyone else's claim.

Origin

The term comes from the bellwether, the lead sheep wearing a bell that the flock follows. Bellwether trials became common in federal multidistrict litigation and large state consolidated dockets in the late twentieth century as a way to manage thousands of similar claims.

Significance in Asbestos Context

Bellwether trials are a feature of mass tort litigation, such as the talc cases, where many claims share common questions about a product. Asbestos personal-injury cases, by contrast, are usually tried one plaintiff at a time because each person's work history, products and disease differ, and the federal asbestos MDL focused largely on resolving cases individually. Where bellwethers are used, the selection of cases matters: each side wants cases that represent the larger group. A bellwether verdict does not bind other plaintiffs, but a string of plaintiff or defense verdicts can shift settlement values across the docket. For an individual plaintiff in a group, a bellwether can mean waiting while test cases go first.

Example Sentence

The court selected six cases for bellwether trials, and the parties reached a global settlement after the third verdict.

Notes

• If your case is part of a group, ask your lawyer how bellwether results might affect your timeline and options.
• A verdict in someone else's case does not decide yours.
