D.C. Code § 16-1002: Complaint of criminal conduct.

A petitioner has a right to seek relief under this subchapter. This right does not depend on the decision of the Attorney General, the United States Attorney for the District of Columbia, or a prosecuting attorney in any jurisdiction to initiate or not to initiate a criminal or delinquency case or on the pendency or termination of a criminal or delinquency case involving the same parties or issues. Testimony of the respondent in any civil proceedings under this subchapter shall be inadmissible as evidence in a criminal trial or delinquency proceeding except in a prosecution for perjury or false statement.
