The lawsuit was filed this week in Sierra County by Tierra Blanca High Country Youth Program.
Students from the Tierra Blanca ranch have attended Deming High School
Last week, the Albuquerque Journal reported state investigators were looking into allegations teenage boys were beaten and forced to wear leg shackles and handcuffs for minor infractions of ranch rules.
The suit claims the ranch was targeted following a fatal car crash involving students. It also alleges Gov. Susana Martinez was among the officials who called to direct parents to withdraw their children.
Martinez's office denies she made any such calls, but says she has been briefed on the investigation.
Ranch owner Scott Chandler said earlier that he is proud of the ranch’s success in serving families and their at-risk children over the years.
