D.C. Mun. Regs. tit. 4, r. 4-214
An award of compensatory damages, civil penalties or attorney's fees pursuant to these guidelines shall be made only upon written petition of the prevailing complainant, specifying the type and amount of damages claimed. Such petition may be contained in the complainant's pre-hearing statement as outlined in the Commission's Rule of Procedure for Contested Cases, 4 DCMR § 413.3.
Any award made for expenses compensable under §§ 202, 203, 204, 205, and 206 of these guidelines shall be made only upon the production of documentary evidence of such expenses, including, but not limited to, bills, receipts, cancelled checks, and invoices.
If such documentation cannot reasonably be produced, an award may be made upon reasonable and credible testimony and evidence.
Any award of damages or other compensation under §§ 201, 202, 205, 207, 208, 209, 210, 211, 212, and 213 of these guidelines shall be made only upon reliable and probative evidence that will permit the Commission to ascertain a reasonable basis for assessing the amount of the damages or other compensation.
If an award of damages is made, the respondent shall pay the complainant interest at the rate of eight percent (8%) per annum on out of pocket expenses, from the date incurred to the date of payment, and if the total award is not paid within thirty (30) days from the date of issuance of the Commission's Final Decision and Order, the respondent shall pay interest at the rate of eight percent (8%) per annum until paid.
