The Supreme Court won't revive a student's lawsuit against a school that punished her for talking about her religion during her high school graduation speech.

The high court on Monday refused to hear an appeal from Erica Corder. She was punished for her 2006 speech at the Lewis-Palmer High School commencement in Monument, Colo.

School officials screened Corder's speech in advance but she changed her text, urging the audience to consider the Christian faith.

The principal made her to write a letter acknowledging the remarks were her personal views before she was given her diploma.

Corder sued, but federal courts threw out her lawsuit. Judges say the school didn't violate her rights because her remarks were school-sponsored, rather than private speech.
