When did the law change where now the da can take it upon himself and procute the The criminal in a domestic violence case

Not sure I understand your quesiton. But, in California, its up to the DA's office whether or not to file charges against someone. If the DA's office has decided to file charges against, your are forced to deal with it. If you are able you should shire a lawyer as soon as possible. It may be possible to have those charges dropped before things go to far.
