Tetra Tech EC, Inc. v. AIG Specialty Insurance Company, et al. — 9th Cir. (Sep 1, 2026)
The Ninth Circuit considers whether AIG had to defend Tetra Tech against three lawsuits arising from cleanup work at Hunters Point Naval Shipyard. The underlying complaints accuse Tetra Tech of falsifying test results and mishandling radioactive soil, while also pleading negligence. The question is whether those allegations created any potential for liability covered by Tetra Tech's pollution policies, or whether the policies' terms and exclusions foreclosed coverage.
Tetra Tech EC, Inc. v. AIG Specialty Insurance Company, et al. (No. 25-7620) — U.S. Court of Appeals for the Ninth Circuit, argued September 1, 2026.
