A carve-out in a state law passed this year as an amendment to the state education budget that exempts ultra-Orthodox Jewish schools from meeting minimum educational standards violates the establishment clause of the Constitution, an advocacy group alleges in a suit filed on Monday.

Quinn Emanuel Urquhart & Sullivan, representing the Young Advocates for Fair Education (YAFFED) group, which advocates for improving educational curricula in ultra-Orthodox schools, alleges in a suit filed in the U.S. District Court for the Eastern District of New York that the amendment effectively creates a “dual oversight” regime for yeshivas and for nonpublic schools in New York, which are required to give instruction that is “substantially equivalent” of that provided to public schools students.
