Does silence mean “without prejudice”?

The district court dismissed fraud claims against an accounting firm for not complying with a Louisiana pre-suit review requirement. The Fifth Circuit affirmed but remanded for clarification as to whether the dismissal was with, or without, prejudice. Fed. R. Civ. P. 41 generally assumes that silence means “with prejudice,” but the Supreme Court has recognized that that rule’s exception for “jurisdiction” goes so far as “encompassing those dismissals which are based on a plaintiff’s failure to comply with a precondition requisite to the Court’s going forward to determine the merits of his substantive claim.”
