In June 2015, the Colorado Supreme Court struck down a successful voucher program in Douglas County, invoking a provision of the state constitution that harks back to an era of widespread prejudice against Catholics. But because of the court's reliance on this discriminatory provision, its decision could well be overturned by the U.S. Supreme Court--clearing the way for voucher programs across the country. The state of the Colorado voucher program is briefly discussed in this article. Douglas County school officials will likely take their case to the Supreme Court, where they will have a smorgasbord of lofty constitutional provisions to choose from, including freedom of speech and equal protection. Their primary argument, though, will be grounded in the First Amendment's guarantee of free exercise of religion.
