Here is the opinion in Scott v. Oklahoma Secondary School Activities Assn.:
A summary of the case by Chad Smith, who represented the players:
The OSSAA suspended 12 students at Sequoyah High School in Tahlequah and did not let compete in the state football championships. Sequoyah is an Indian boarding school run by the Cherokee Nation. The Oklahoma Supreme Court found the OSSAA was arbitrary and capacious and reversed the District Court.
