Wrongful Restraining Order Made by My Daughter Against My Boyfriend

My question involves restraining orders in the State of: California
My daughter has filed a wrongful restraining order against my boyfriend, whom we live with. She is a out of control teen that is upset about the disciplinary actions we have taken against her at home and has filed a restraining order against him claiming she feels threatened.
What is the likelihood it can get thrown out?
