Res Judicata latin

A matter judged / already adjudicated • Hindi: पूर्व-न्याय / प्रांग्न्याय (Section 11, CPC)

A fundamental doctrine prohibiting courts from trying any suit or issue in which the matter directly and substantially in issue has been heard and finally decided by a competent court between the same parties.

The mental element of intention, knowledge, recklessness, or malice required to constitute a crime along with actus reus (the guilty physical act).

The infringement of an absolute private legal right of the plaintiff which is actionable per se, even if the plaintiff suffered no pecuniary or physical loss.
