Diane Zilka v. City of Philadelphia, Tax Review Board

Paid petition · Supreme Court of Pennsylvania, Eastern District, No. 20 EAP 2022, 21 EAP 2022 · judgment November 22, 2023


Certiorari denied · January 13, 2025
Pre-decision estimate: 12% cert probability (95% interval 8%–17%)

Before the decision, about 2.9× the 4.1% base rate. The model weighted this up for counsel who has won certiorari before, a circuit split argued in the petition, and a dissent in the court below (flagged in the petition), and down for a state or local-government respondent.

Question presented

Whether the Commerce Clause requires states to consider a taxpayer’s burden in light of the state tax scheme as a whole when crediting a taxpayer’s out-ofstate tax liability as the West Virginia and Colorado Supreme Courts have held and this Court has suggested, or permits states to credit out-of-state state and local tax liabilities as discrete tax burdens, as the Pennsylvania Supreme Court held below.
