LA Bar · Get comfortable with the vocabulary.

Cause of action

A set of facts giving rise to a legal right to sue for relief. Under Louisiana's fact pleading, a petition need only state the material facts, not the legal theory, to survive an exception of no cause of action.

Related: Exception of no cause of action, Fact pleading
Exception of no cause of action

A peremptory exception testing whether the law grants any remedy on the facts alleged. The court accepts well-pleaded facts as true and asks only whether the petition states a legally recognized claim.

Related: Cause of action, Peremptory exception
Peremptory exception

An objection that defeats or terminates a claim, such as prescription, res judicata, no cause of action, or no right of action. It may be raised at any time before submission of the case, and some may be noticed by the court on its own motion.

Related: Exception of no cause of action, Prescription
Liberative prescription

A period after which a party is barred from enforcing a right by action, akin to a statute of limitations. It is distinguished from acquisitive prescription, which creates rights through possession over time.
