What it's about

Zamrzla and the other petitioners sought Supreme Court review of a California appeals court case involving the Antelope Valley Watermaster.

Question presented

1. What minimum due process protections are required before absent class members may be bound by a class judgment that substantially impairs their real-property rights and exposes them to monetary liability, rather than merely extinguishing claims for money damages? 2. Does due process require that class members be afforded the right to opt out of the class action where the action does not predominantly concern monetary claims but nonetheless adjudicates monetary claims against class members who are subject to the forum court’s personal jurisdiction?
