The U.S. Supreme Court has rejected an appeal from two Colorado Christian high schools that wanted the University of California to grant college-prep credit for religious courses.

The Association of Christian Schools International and co-plaintiff Calvary Chapel Christian School accused the university of violating freedom of speech and religion for refusing to honor the courses when considering admissions eligibility.

The justices, however, denied them a hearing without comment.

Calvary's attorney, Robert H. Tyler of the Murrieta firm Advocates for Faith and Freedom, said Tuesday's ruling was a "green light to discriminate against Christian viewpoints."
     
The court decision affirms a 2008 lower court ruling by U.S. District Judge S. James Ortero who said the schools had failed to prove religious intolerance.
