Legal Word of the Day: “Res Judicata”


“Res Judicata” — A form of estoppel, this doctrine provides judicial finality.

Cause of action estoppel prevents a party from relitigating a claim that was decided or could have been raised in an earlier proceeding. Issue estoppel is narrower than cause of action estoppel.

Res judicata prevents a party from relitigating an issue already decided in an earlier proceeding, even if the causes of action in the two proceedings differ.
