Council Chairman Phil Mendelson will file a lawsuit Wednesday against the mayor and CFO, challenging their refusal to recognize validity of last year’s budget autonomy referendum. (Sarah L. Voisin/The Washington Post)

It was probably destined to come to this: With all sides locked into conflicting positions on the validity of last year’s budget autonomy referendum, it will now be up to a judge — or, more likely, a D.C. Court of Appeals panel — to determine if the ballot measure means the city can now spend local funds without a separate congressional appropriation. D.C. Council Chairman Phil Mendelson will file a lawsuit this morning on behalf of his colleagues against Mayor Vincent C. Gray and Chief Financial Officer Jeffrey S. DeWitt, asking the court to determine whose legal rationale is correct. If the council prevails, it will vindicate their novel, long-shot approach to a nettlesome problem; if not, it’s back to beseeching Congress to address the issue.
