As I noted earlier, it really isn’t necessary for the District’s laws to refer repeatedly to the “Mayor of the District of Columbia.” Really, “Mayor” is just fine. And if you weren’t sure, we even have a law that says so.
But if you insist on using the full title in every freaking paragraph of the law, I suppose I shouldn’t be surprised to encounter the following:
“The Mayor may…delegate…to an agency of the government of the District of Columbia, designated or established by the Mayor of the District of Columbia.” (Of course, a delegation provision is pretty unnecessary, too, as the Home Rule Act specifies that the Mayor may delegate anything he darn well feels like delegating other than approving or vetoing legislation.)
