The Commission may order the deposition of any person in aid of any investigation or proceeding.
The deposition shall be taken in the form prescribed by the Commission, and shall be subject to any limitations prescribed by the Commission.
To compel a deposition, the Commission may petition the Superior Court of the District of Columbia requesting an order requiring a person to appear and testify and to produce papers, books, records, accounts, documents, transcriptions, or other physical things before a member of the Commission or a special counsel or other officer designated by the Commission.
The petition to the Superior Court shall state, without identifying the judge, the general nature of the pending matter, the name and residence of the person whose testimony or other evidence is desired, and any special directions the Commission may prescribe.
Depositions shall be taken and returned in the manner prescribed by law for civil actions.
