OXNARD, Calif. (KTLA) — An Oxnard teacher who was fired after her past as a porn actress was discovered by students lost her legal bid to regain her job.

Stacie Halas, a science teacher at Richard B. Haydock Intermediate School, was fired by the school board last April on the grounds that her role in pornography disrupted the classroom environment.

Halas appealed her firing before the Commission on Professional Competence.porn-teacher

On Tuesday, her attorney Richard Schwab said a three-judge panel unanimously decided the 32-year old was unfit for the classroom.

During a hearing last fall, Schwab had argued that Halas did not star in pornographic movies while teaching in any district.

He said Halas acted in them during an eight-month period from 2005 to 2006 because of financial duress.

Nitasha Sawhney, one of two lawyers representing the school district, said Halas repeatedly lied to school administrators about her acting career at the same time students were viewing the explicit videos.

“This case is about whether the students of the Oxnard School District are required to incorporate into their learning environment the choice Ms. Halas made to be a porn star,” Sawhney said.

The investigation began when students approached administrators at the school and told them they had seen a female teacher in a pornographic video.

Administrators tried to verify the students’ claims, but couldn’t because the school’s computers have filters on them that prevent access to sites featuring pornographic material, Superintendent Jeff Chancer said.

So administrators put out a memo to school staff, acknowledging the students’ claims but saying they were only unverified rumor.

That’s when some other teachers came forward and showed administrators the video on a cell phone, allowing them to tentatively confirm that the accused teacher appeared in the X-rated video.

Chancer showed the video to district attorneys and the accused teacher was then placed on leave by district officials, he said.

Chancer applauded the commission’s ruling.

Halas’ decision to “engage in pornography was incompatible with her responsibilities as a role model for students and would present an insurmountable, recurring disruption to our schools should she be allowed to remain as a teacher,” he said in a statement.
