A decision of the hearing officer which is in favor of DCHA, or denies the complainant his or her requested relief in whole, or in part, shall not constitute a waiver of, or affect in any manner whatever, rights the complainant may have to a trial de novo in judicial proceedings which may be later brought in the matter.
In de novo judicial proceedings, neither party shall be limited to invoking against the other the grounds originally relied on in the administrative proceedings.
