Invenergy Thermal LLC, et al. v. Casey Sixkiller, Director, Washington State Department of Ecology

Paid petition · United States Court of Appeals for the Ninth Circuit, No. 23-3857 · judgment December 24, 2024


Certiorari denied · October 6, 2025
Pre-decision estimate: 8% cert probability (95% interval 5%–12%)

Before the decision, about 1.9× the 4.1% base rate. The model weighted this up for counsel who has won certiorari before, a Ninth Circuit decision below, and a petition filed soon after the judgment below, and down for a state or local-government respondent.

Questions presented

  1. Whether this Court’s decision in General Motors Corp. v. Tracy, 519 U.S. 278 (1997), immunizes State laws affecting utilities from challenge under the dormant Commerce Clause, even when those laws affect competitive markets.

  2. Whether alleging interstate and market-wide consequences of a state law, including a protectionist effect, adequately alleges a burden on interstate commerce, as five Justices would have held in National Pork Producers Council v. Ross, 598 U.S. 356 (2023).
