Using a Rule 12(f) Motion to Strike Class Allegations in the Ninth Circuit: The Aftermath of Whittlestone
By Alona G. Metz
Last year, the Ninth Circuit curtailed the use of Rule 12(f) motions to strike in a case of first impression called Whittlestone, Inc. v. Handi-Craft Co., 618 F.3d 970 (9th Cir. 2010). The narrow holding of Whittlestone is that "Rule 12(f) does not authorize district courts to strike claims for damages on the ground that such claims are precluded as a matter of law." Id. at 974-975. Rule 12(f) of the Federal Rules of Civil Procedure states that a district court "may strike from a pleading an insufficient defense or any redundant, immaterial, impertinent, or scandalous matter." "The function of a 12(f) motion to strike is to avoid the expenditure of time and money that must arise from litigating spurious issues by dispensing with those issues prior to trial . . . ." Fantasy, Inc. v. Fogerty, 984 F.2d 1524, 1527 (9th Cir. 1993) (overruled on other grounds in Fogerty v. Fantasy, Inc., 510 U.S. 517 (1994)).
