WASHINGTON (Reuters) — The U.S. Supreme Court on Monday handed a victory on narrow grounds to a Colorado Christian baker who refused for religious reasons to make a wedding cake for a gay couple, stopping short of setting a major precedent allowing people to claim exemptions from anti-discrimination laws based on religious beliefs.The justices, in a 7-2 decision, said the Colorado Civil Rights Commission showed an impermissible hostility toward religion when it found that baker Jack Phillips violated the state’s anti-discrimination law by rebuffing gay couple David Mullins and Charlie Craig in 2012.
