In United Steel, Paper & Forestry, Rubber, Manufacturing, Energy, Allied Industrial & Service Workers International Union, AFL-CIO, CLC, et al. v. Shell Oil Company (9th Cir. Apr. 21, 2010) (say that three times fast), a putative class action alleging various wage & hour violations was removed to federal district court pursuant to 28 U.S.C. § 1332(d)(2) (CAFA). Certification was eventually denied. The district court concluded that it lacked jurisdiction and remanded the matter to state court. On appeal, the Ninth Circuit joined the Seventh and Eleventh Circuits in holding that denial of class certification does not divest the federal district court of jurisdiction. The Court recognized the general principles that jurisdiction is evaluated at the time it is invoked, and subsequent developments do not destroy jurisdiction if it was properly invoked originally. All else equal, this decision should reduce the overall degree of hapiness experienced by district court judges. Now they can't put an unsuccessful, removed class action out of its misery with a remand bullet to the head. Thus, federal district courts will have the pleasure of overseeing more individual, state law-based actions.
