A limited California rule may protect testimony from a formal probation-revocation hearing when related criminal charges have not yet been decided. Under People v. Coleman, on a timely objection the probationer’s revocation-hearing testimony and evidence derived from it generally cannot be used against that person in a later proceeding on the related charges. This is a case-specific evidentiary rule, not transactional immunity or a blanket right to remain silent at every hearing. (People v. Coleman)

The timing and connection matter: the testimony must come from a formal revocation hearing held before disposition of related charges, and the later proceeding must involve those related charges. If another unrelated case is pending, do not assume this rule covers it. Counsel may need to make a timely objection and establish the relationship between the revocation allegations and the criminal charges. (People v. Coleman)

There is a narrow later-use exception. If the defendant testifies at the criminal trial and the testimony is clearly inconsistent enough to warrant admission to show probable perjury, the revocation testimony may be used for impeachment or rebuttal after a judicial ruling. Simply taking the stand does not automatically open the door. (People v. Coleman)

This does not automatically postpone the revocation hearing

The rule does not stop the probation court from holding the revocation hearing while new charges are pending. People v. Weaver rejected a routine stay requirement; a defendant cannot assume the later trial will happen first or that the revocation will be postponed on request. (People v. Weaver)

Before the hearing, preserve the revocation notice and alleged violations, the new charging document, hearing date, any transcript or recording, and the sequence of court dispositions. Counsel can compare the facts underlying each case and raise the proper objection if testimony or its fruits are later offered. This rule addresses testimony at a formal probation-revocation hearing, not testimony in a civil restraining-order case or every probation interview.
