We’ve already mentioned this in the context of the Chrysler bankruptcy (criticized in some quarters for having divested the reorganized company of punitive damage exposure over pre-bankruptcy conduct) but here’s Drug and Device Law gathering up decisions from various states to confirm that, no, there is no vested or constitutional right to punitive damages:
Constitutional challenges have been rejected under due process, taking, jury trial, open courts and various other state constitutional provisions. It makes sense. While compensatory damages might present a closer question (depending on issues such as retroactivity), there’s simply no constitutional right for one private party to demand that another private party be punished.
Especially not when the putative purpose of the damages, to inflict financial distress on the target, has been obviated by an intervening bankruptcy.
