MEMORANDUM

Plaintiffs Kimbra Gottschall, Debra Ga-ball, Raymond Gottschall, Robert W. Gottschall, and Ronald Gottschall appeal the district court’s summary judgment in favor of Defendants General Dynamics Corporation and Huntington Ingalls, Inc. We vacate the judgment and remand for further proceedings.

The California Supreme Court has recently made clear that the summary judgment entered by the district court, in reliance on a decision by the multidistrict litigation court in Pennsylvania, was based on an incorrect understanding of California law. In Webb v. Special Electric Co., Inc., 63 Cal.4th 167, 189-90 , 202 Cal.Rptr.3d 460 , 370 P.3d 1022 (2016), the California Supreme Court held:

In light of Webb and the California Supreme Court’s dismissal of a petition for review in Gottschall v. Crane Co., 230 Cal.App.4th 1115 , 179 Cal.Rptr.3d 39 (2014), dismissed and remanded by 203 Cal.Rptr.3d 665 , 373 P.3d 471 (Cal. 2016), we conclude that the summary judgment based on this theory must be vacated.

The district court never ruled on Defendants’ government contractor defense. Defendants argue it to us as an alternative basis to affirm the summary judgment, but genuine disputes of material fact preclude that result. The government contractor defense is essentially a defendant’s assertion that “the Government made me do it.” In re Hawaii Fed. Asbestos Cases, 960 F.2d 806, 813 (9th Cir. 1992). To prevail, the defendant “must show that it acted in compliance with reasonably precise specifications imposed on it by the United States in deciding whether to provide a warning.” Getz v. Boeing Co., 654 F.3d 852, 866 (9th Cir. 2011) (citation, internal quotations and alteration omitted). Here, the parties pointed to conflicting evidence regarding the Navy’s labeling policies, so summary judgment is not appropriate.

We decline to address Defendants’ arguments based on O’Neil v. Crane Co., 53 Cal.4th 335, 135 Cal.Rptr.3d 288 , 266 P.3d 987 (2012) and McIndoe v. Huntington Ingalls Inc., 817 F.3d 1170 (9th Cir. 2016), because they were not developed in the district court. See Chadd v. United States, 794 F.3d 1104 , 1109 n. 4 (9th Cir. 2015) (declining to address arguments raised for the first time on appeal). These arguments are more appropriate for adjudication in the first instance by the district court on remand.

Costs are taxed in favor of Plaintiffs and against Defendant-Appellee.

VACATED AND REMANDED.
