All citations should have been shepardized. This is standard practice for lawyers for decades. Court rules always require you only cite good law. So you will be excortiated for valid but overturned citations too.

This is actually one of the more infuriating things about all of this. Non-lawyers read this stuff and they’re like oh look it hallucinated some cases and citations. It actually should still have been caught 100% of the time and anyone submitting briefs without verifying their cites is not fit to be a lawyer. It's malpractice, AI or not.
