Allegheny County will have to find out through the normal course of litigation if its real property assessment system is constitutional after the Pennsylvania Supreme Court rejected a petition to exercise its King’s Bench or extraordinary jurisdiction over the case.

The Allegheny County Council, through its counsel John F. Cambest of Dodaro Matta & Cambest in Pittsburgh, had asked Pennsylvania’s high court to formulate a test to determine when a property assessment framework violates the uniformity clause of the state constitution, according to the petition in Clifton v. Allegheny County .
