The district voted to fire Stacie Halas last week. She taught seventh and eighth grade science at Richard B. Haydock Intermediate School. An attorney for the 32-year-old said Friday that she will contest the allegations against her.
Lawyer Richard Schwab told the Ventura County Star that Halas engaged in "lawful conduct" in a "very vibrant" business for California.
Halas has 30 days to appeal the decision.
