"The Roman Catholic Archdiocese of San Juan, Puerto Rico, filed for bankruptcy ... following a $4.7 million judgment in cases brought by pension plan participants against the Superintendence of Catholic Schools of the Archdioceses of San Juan.... [T]he Puerto Rico Supreme Court [had] authorized the immediate seizure of church assets from across the island ... to pay the judgment, prompting the archdiocese's bankruptcy filing to stay all litigation. An earlier attempt by the pension plan to declare bankruptcy was denied by the court."
