Legal Question in Criminal Law in California

The law on informants has several twists. If the informant is a percipient witness, then you may be entitled to their identity. If they just provided information to establish probable cause in support of a search warrant, then it's a different analysis.

The judge may be required to conduct a hearing on the issue of whether or not the informant must be disclosed under any number of theories.

Only your attorney can answer this question completely. They have access to all the evidence, witness statements, etc.

Can a judge order disclosure of a CI? Yes. Will they? That depends on the particular facts in your case.

It can only be disclosed based on the judge's ruling on a motion. You should have an attorney. In criminal law, you get an attorney appointed for you if you cannot afford one. There is absolutely no excuse for you to not have an attorney, and you do not have the time to teach yourself law before you get convicted.
