The U.S. Court of Appeals for the Second Circuit said Monday that it would not lift state prison restrictions that a group of Quaker inmates argued had interfered with the practice of their religion.

The ruling, from a three-judge panel of the Manhattan-based appeals court, denied a request for a preliminary injunction by the inmates, who claimed that scheduling changes at the Green Haven Correctional Facility in Stormville, New York, made it harder to hold quarterly religious gatherings and “meetings for worship with a concern for business.”
