Gemini on Question 48, Sep 20

Is Varghese v. China Southern Airlines Co., Ltd., 925 F.3d 1339 (11th Cir. 2019) still good law? Quote its holding for me.

Yes, Varghese v. China Southern Airlines Co., Ltd., 925 F.3d 1339 (11th Cir. 2019) is still good law. It has not been overturned or abrogated by the Eleventh Circuit sitting en banc or by the U.S. Supreme Court.

The case resolved an issue of first impression in the Eleventh Circuit regarding international air travel: whether the Montreal Convention (the international treaty governing airline liability) merely preempts state law, or whether it actually provides a standalone federal cause of action that plaintiffs can sue under directly.

The Eleventh Circuit concluded that the treaty does provide its own cause of action. The court explicitly stated its holding as follows:

"We hold that the Montreal Convention creates an independent cause of action."

By doing so, the Eleventh Circuit aligned itself with other federal circuits, confirming that passengers bringing claims falling within the scope of the treaty (such as flight delays under Article 19 or injuries under Article 17) can, and indeed must, bring their claims directly under the federal cause of action created by the Montreal Convention rather than relying on state-law claims.
