Complaint Lacking Legal Theory

Conclusory Allegations Rejected

Common questions
Frequently Asked
4
What standard does a court apply when deciding a Rule 12(b)(6) motion?+
The court accepts all well-pleaded factual allegations as true and draws reasonable inferences in the plaintiff's favor. It then determines whether those facts plausibly state a claim for relief rather than merely a possible one.
Supporting sources
Can a defendant raise failure to state a claim after answering the complaint?+
Yes. Although the defense is ideally raised in a pre-answer motion, Rule 12(h)(2) permits it to be raised later by motion for judgment on the pleadings or at trial.
Supporting sources
How does Rule 12(b)(6) differ from a motion for summary judgment?+
A 12(b)(6) motion tests only the legal sufficiency of the pleadings and assumes the facts alleged are true. Summary judgment examines the actual evidence after discovery to determine whether a genuine dispute of material fact exists.
Supporting sources
What happens if the court grants a Rule 12(b)(6) motion?+
The claim is dismissed. Unless the court specifies otherwise or the plaintiff obtains leave to amend, the dismissal is typically without prejudice to refiling a corrected complaint.
