D.C. Code § 5-131.03

(a) Notwithstanding the limitations of existing law, the person who is the Director of the Metropolitan Police Force band may elect to retire after having served 10 or more years in such capacity and having attained the age of 70 years. Upon such retirement, whether for age and service or for disability, said Director and his surviving spouse or domestic partner, shall be entitled to receive annuities in amounts equivalent to, and under the conditions applicable to, the annuities which a captain in the Metropolitan Police force and his surviving spouse or domestic partner, may be entitled to receive after such captain has retired from said force for substantially the same reason as that for which said Director may retire, whether for age and service or for disability, as the case may be. If the said Director shall apply for retirement for disability, he shall not be eligible to retire under § 5-710 , but he shall be eligible to apply for retirement under § 5-709 , in like manner as if the said Director were an officer or member of the Metropolitan Police force. The annuities hereby authorized shall be in addition to any pension or retirement compensation which said Director may be entitled to receive from any other source, whether from the United States or otherwise. The annuities payable to said Director and his surviving spouse or domestic partner pursuant to this subchapter shall be payable from District of Columbia appropriations, but shall not be considered as annuities payable to an officer or member of the Metropolitan Police force or to the surviving spouse or domestic partner, of such officer or member. Appropriations for the operations of the Metropolitan Police Department are made available for this purpose. Annuities authorized by this section shall be computed on the basis of compensated service rendered after July 11, 1947.
(b) For the purposes of this section, the term “domestic partner” shall have the same meaning as provided in § 32-701(3) .
