Below is the PC you sited. It is not a law that you can violate. It is just a law that states that a prisoner on parole is still "in custody" and can be taken back to jail at any time. So they are just citing their authority to return him to prison.
3056. Prisoners on parole shall remain under the legal custody ofthe department and shall be subject at any time to be taken backwithin the inclosure of the prison.
So...if he's being charged for something else, they will cite this?
