The plaintiffs, a group of inmates held at the Massachusetts Correctional Institute in Concord, filed suit against Massachusetts prison officials for alleged violations of their rights under the First and Fourteenth Amendments and the Religious Land Use and Institutionalized Persons Act (RLUIPA). The plaintiffs alleged that the prison officials violated these rights by refusing to provide separate accommodations for adherents of the Nation of Islam, whose practices (according to one of the plaintiffs) are "distinctly different" from those of Sunnī Islam. The magistrate judge recommended that the defendants' motion to dismiss be allowed because the plaintiffs had not yet exhausted their administrative remedies within the prison system.
