In one sentence

In Rosie Casampol Trahan v. Wal-Mart Associates, Judge Hixson remanded the employment case to state court because Walmart did not show the supervisor was fraudulently joined.

Who this affects

Trahan’s case will proceed in the Superior Court for the County of Contra Costa rather than federal court. Wal-Mart Associates, Inc. and Allison Ferra remain defendants, and each side must bear its own costs and fees for the removal and remand proceedings.

What happened

Rosie Casampol Trahan sued Wal-Mart Associates, Inc. and Allison Ferra in California state court over employment claims including age and disability discrimination, harassment, and wrongful termination. Wal-Mart removed the case to federal court based on diversity jurisdiction, and Trahan asked the court to send it back.

The court held that Ferra’s California citizenship defeated complete diversity unless Wal-Mart could show she was fraudulently joined. Because Trahan alleged that Ferra repeatedly called her old and urged her to retire, and California law allows harassment claims against supervisors, the court found a possibility that Trahan could recover against Ferra. It therefore ruled that removal was improper and remanded the case to the Superior Court for the County of Contra Costa.

Judge Hixson ordered the remand under 28 U.S.C. § 1447(c) and directed each side to bear its own costs and fees related to removal and remand. The order did not decide the underlying employment claims.

Background

Rosie Casampol Trahan sued Wal-Mart Associates, Inc. and Allison Ferra in the Superior Court for the County of Contra Costa. The complaint asserted California employment claims, primarily under the Fair Employment and Housing Act, including age and disability discrimination, harassment, and wrongful termination. Wal-Mart removed the case to federal court under diversity jurisdiction, which generally requires complete diversity of citizenship and more than $75,000 in controversy. Trahan moved to remand the case to state court.

The parties agreed that Trahan and Wal-Mart had diverse citizenship. They disagreed about Ferra, whom the opinion identifies as a California resident. Because Ferra and Trahan were both California citizens, Ferra’s presence would defeat complete diversity. Wal-Mart argued that Ferra was a sham defendant who had been fraudulently joined and therefore should be disregarded for jurisdictional purposes.

Fraudulent Joinder Analysis

The court explained that fraudulent joinder may be established either by actual fraud in pleading jurisdictional facts or by showing that the plaintiff cannot establish any cause of action against the non-diverse defendant in state court. The relevant question was not whether Trahan had pleaded a claim that satisfied the ordinary plausibility standard for a motion to dismiss. Instead, Wal-Mart had to show, by clear and convincing evidence, that there was no possibility—beyond a trivial or frivolous possibility—that a state court could find a cause of action against Ferra.

Trahan focused on her harassment claim against Ferra. The complaint alleged that Ferra said on numerous occasions that Trahan “is old” and urged her to retire. The court stated that the Fair Employment and Housing Act permits a harassment claim against a supervisor based on allegations of this kind. Wal-Mart acknowledged that an individual supervisor or coworker may be liable for harassment under that law.

The court rejected Wal-Mart’s argument that the harassment claim was not plausibly alleged because that argument applied the wrong standard for fraudulent joinder. The court found that Trahan’s claim against Ferra was not wholly insubstantial or frivolous and that Wal-Mart had not shown there was no possibility of a state-court finding in Trahan’s favor.

Ruling

The court ruled that removal to federal court was improper and remanded the case to the Superior Court for the County of Contra Costa under 28 U.S.C. § 1447(c). Each side was ordered to bear its own costs and fees connected with the removal and remand proceedings. The order resolved the location of the case, not the merits of Trahan’s employment claims.
