Bellwether trials serve as test cases that help both sides assess the value of the overall litigation. Courts typically select multiple bellwether cases representing a range of injury severity, geographic diversity, and factual scenarios.

The outcomes of bellwether trials are not legally binding on other plaintiffs but significantly influence settlement negotiations. Consistent plaintiff verdicts typically increase settlement values, while defense verdicts may reduce them.

Bellwether selection is often a contested process, with plaintiffs seeking strong cases and defendants seeking weaker ones. The court ultimately selects cases that are fair and representative of the overall docket.
