A high-volume, heavy-advertising New York personal injury law firm and a Washington, D.C., advocacy group are apparently the first to challenge the new attorney advertising restrictions that took effect Thursday.

On the same day the new rules were implemented, Alexander & Catalano, with offices in Syracuse and Rochester, N.Y., and Public Citizen Inc. filed a federal lawsuit in the Northern District alleging the restrictions violate the constitutional right to free speech and impose anti-consumer limits on lawyers’ ads.
