A lawyer challenging the D.C. Council’s decision to delay the city’s first election of an attorney general lost his bid to require city election officials to include him on the ballot.

D.C. Superior Court Judge Laura Cordero today denied challenger Paul Zukerberg’s motion for a preliminary injunction, finding he failed to show he would suffer “irreparable harm.” Zukerberg, a candidate for the position of attorney general, sued to block a D.C. Council bill passed in October delaying the election from 2014 until at least 2018.
