• California has won a $700 million decision in punitive damages against French holding company Artémis. Artémis, owned by French billionaire François Pinault [Wikipedia profile], was sued for its role in the 1990s sale of Executive Life, a now-defunct insurance company that California's Insurance Commission [official website] took over following the sale. The jury did not find actual damages for the state, which Artémis' lawyers say precludes the rewarding of any punitive damages. The state's attorneys argue that California law allows punitive damages in place of actual damages where the defendant had received "ill-gotten gains" through its acts. Bloomberg has more.
