Years of legal strategizing comes down to this: U.S. District Court Judge Emmet G. Sullivan will hear arguments this morning on whether last year’s budget autonomy referendum has any legal effect and is likely to rule on the question shortly thereafter. The court case is an unusual one, pitting branches of the District government against each other, with Capitol Hill leaders on the sidelines hoping to influence the case. House Republicans have filed a friend-of-the-court brief arguing that the referendum is invalid; top Democratic leaders declined to join them. Sullivan’s ruling may not be the end of the matter: Attorney General Irvin B. Nathan, who is expected to personally argue this morning, has hinted that even a pro-referendum ruling might be appealed.
