D.C. Code § 16-2388: Adjudicatory hearings.

(a)

The court shall begin the adjudicatory hearing by determining whether all parties are present and whether proper notice of the hearing has been given. If a parent has been given proper notice but fails to appear, the court may proceed in the parent’s absence.

(b)

The court shall hear evidence presented by the moving party and the burden of proof shall rest upon the moving party.

(c)

Every party shall have the right to present evidence, to be heard in his or her own behalf, and to cross-examine witnesses called by another party.

(d)

All evidence which is relevant, material, and competent to the issues before the court shall be admitted.

(e)

Notwithstanding the provisions of sections 14-306 and 14-307, neither the spouse or domestic partner privilege nor the physician/client or mental health professional/client privilege shall be a ground for excluding evidence in any proceeding brought under this subchapter.

(f)

The court may enter, modify, or terminate a guardianship order after considering all of the evidence presented, including the Mayor’s report and recommendation, and after making a determination based upon a preponderance of the evidence that creation, modification, or termination of the guardianship order is in the child’s best interests. If the court does not find that sufficient grounds exist to create, modify, or terminate a guardianship order, the motion may be dismissed.
