Deanna Allen, Janice Mireles and Rosalinda Padilla are suing the school for damages for alleged loss of income, mental anguish and damage to their reputations, The San Antonio Express-News reported Tuesday.
The three, who taught high school and junior high-level classes, say they were fired after stories about the alleged parties ran in a local newspaper and on a local television newscast.
The newscast on KENS-TV, San Antonio, said three anonymous teachers complained the school's principal took part in the parties and kept some of the items she purchased in her office.
The lawsuit does not specify that the three plaintiffs were the anonymous teachers mentioned but does claim their First Amendment rights were violated.
Attorney Edward Pina, in the lawsuit petition, called the terminations "unlawful, oppressive and unconstitutional."
