Hayes v. Gulf Oil Corp.
From Conservapedia
In Hayes v. Gulf Oil Corp., 821 F.2d 285 (5th Cir. 1987), the Court of Appeals for the Fifth Circuit held that the failure of a lessee to raise a defense of improper venue in its first pleading or in a pre-pleading motion did not prevent the court from holding that it lacked subject matter jurisdiction over the lawsuit.
