Despite the Erie Doctrine, federal law limits the equity jurisdiction of federal courts.  Federal courts may not issue equitable relief if the plaintiff has an adequate remedy at law, and that rule holds true even in a diversity case otherwise governed by state law and even though state law might allow state courts, hearing the same claim, to award equitable relief regardless of the adequacy of legal remedies.  Here, plaintiff had adequate legal remedies which he voluntarily chose not to pursue in hopes of a court trial of his case.  His suit solely for equitable remedies for the same wrongs was then properly dismissed despite his claim that under California law, equitable remedies were available under the CLRA and UCL without regard to the adequacy of legal remedies for those wrongs.
