> Entries deemed by CTA in their sole discretion to be immoral, obscene, indecent, profane or not in keeping with CTA’s image will be disqualified. CTA reserves the right in its sole discretion to disqualify any entry at any time which, in CTA’s opinion, endangers the safety or well being of any person, or fails to comply with these Official Rules.
