By refusing to hear a case involving challenges to Pennsylvania’s school funding system, the U.S. Supreme Court yesterday cleared the way for the plaintiffs to begin gathering evidence to prove their claim that the state gives less money to districts that are predominantly minority.

Without comment, the justices let stand an August decision from the 3rd U.S. Circuit Court of Appeals that revived the case, Powell v. Ridge, and sent it back to U.S. District Judge Herbert J. Hutton who had initially dismissed it.
