Fifth Circuit expands res judicata application to non-merit-based decisions

30/04/2025
A wooden gavel rests on a sound block in the foreground, with a balanced scale of justice in the background. The setting appears to be a courtroom or a law library, indicated by the blurred shelves filled with books.

“Under res judicata, a final judgment on the merits of an action precludes the parties or their privies from relitigating issues that were or could have been raised in that action.” Allen v. McCurry, 449 U.S. 90, 94 (1980).

Sometimes, res judicata may extend beyond that. As illustrated in the case below, a prior action may, under certain circumstances, bar a later action even when there has been no decision on the merits of the first action.

Pie I: Pie Development vs. Pie Insurance Holdings

Pie Development sued two former employees and some companies established by them for misappropriation of trade secrets and related claims.

The district court in Pie I dismissed the case without prejudice (i.e. even though the court decided to dismiss the case, it would be possible to re-issue the claim in the future), finding that Pie Development’s complaint lacked sufficient detail, and ordered it to file an amended complaint within 30 days.

Instead of amending its complaint, Pie Development appealed the district court’s dismissal.

The Fifth Circuit affirmed the district court’s decision and also denied Pie Development’s alternative request for leave to amend.

Pie II: Pie Development LLC vs. Pie Carrier Holdings

While the appeal in Pie I was pending, Pie Development filed another action in the district court against additional defendants. After losing the appeal in Pie I, it added the original Pie I defendants to the Pie II action. The Pie II complaint alleged the same claims as Pie I.

Some defendants moved to dismiss based on res judicata, arguing that the claims had already been decided in Pie I. Others moved to dismiss for failure to state a claim. The district court granted both motions, and Pie Development appealed. The Fifth Circuit again affirmed.

Res judicata

In deciding whether res judicata was a proper ground for dismissal, the Fifth Circuit addressed two major issues.

The first issue was whether res judicata could serve as a basis for a motion to dismiss. The court held that, although res judicata is generally an affirmative defense, it may be raised in a Rule 12(b)(6) motion where the bar is apparent from the complaint and judicially noticed facts, especially when the plaintiff fails to challenge the defendant’s failure to plead it as such. The court also noted that it may sua sponte (i.e. of its own accord) address res judicata when all relevant facts are before it and undisputed.

The second issue was whether the court’s decision in Pie I constituted a final judgment on the merits, sufficient to bar the claims in Pie II.

The Fifth Circuit held that it did. Although a dismissal without prejudice typically is not a judgment on the merits, this case was different — Pie Development refused to amend its complaint as directed and instead pursued an appeal. This, the court found, effectively converted the dismissal into one with prejudice — constituting a final judgment for res judicata purposes.

The court analogised Pie Development’s failure to amend and pursue its claims at the district court level to “sleeping on its rights.” Because Pie Development declined to litigate the merits when given the opportunity, res judicata applied.

The court further explained that holding otherwise would undermine the purpose of res judicata. A plaintiff could otherwise avoid dismissal with prejudice by strategically declining to amend and appealing instead, then returning to amend the complaint based on the appellate outcome. Such tactics would unnecessarily burden judicial resources.

Failure to State a Claim

The Fifth Circuit also addressed whether Pie Development met the pleading standard for its trade secret misappropriation claim. It concluded that it had not.

Specifically, the complaint did not plausibly allege that the defendants had the required mental state — such as knowledge or reason to know — that the information was a trade secret.

Pie Development argued that the Pie I litigation gave defendants awareness of the trade secret status of the information, citing Metallurgical Industries, Inc. v. Fourtek, Inc., 790 F.2d 1195, 1204 (5th Cir. 1986), which found that ongoing trade secret litigation can support an inference of knowledge.

The court rejected this argument, distinguishing the present case on the basis that Pie I had concluded. As a result, the defendants were entitled to rely on the Pie I decision, which found no protectable trade secret existed.

Comments

This decision is noteworthy in that the Fifth Circuit, in an unprecedented move, extended the res judicata bar to cases previously dismissed without prejudice when plaintiffs strategically bypassed the trial court and appealed instead.

This case illustrates the significant risk of such a litigation strategy: a dismissal without prejudice may effectively become a permanent bar. Plaintiffs may lose the opportunity to amend and ultimately forfeit their claims without ever ruling on the merits.
