WASHINGTON – The Supreme Court concluded its work for this session on Monday siding with religious institutions in a major church-state decision. The court ruled 7-2 that religious institutions may not be excluded from state programs with a secular intent – in this case, making playgrounds safer. Missouri’s state constitution, like those in about three dozen states, forbade government from spending any public money on “any church, sect, or denomination of religion.” Trinity Lutheran Church in Columbia, Mo., wanted to participate in a state program that reimburses the cost of rubberizing the surface of playgrounds.
