Some good news for the head of Rockland’s Republican Party. The Journal News reported yesterday that DWI charges against 58-year-old Lawrence Garvey of New City have been dropped. A Westchester village court judge found last week the traffic stop that led to his arrest was improper. He had been charged last December with DWI after he reportedly failed all field sobriety tests and refused to submit to blood-alcohol tests. He had been stopped for a broken taillight as he got onto Route 287 in Elmsford. Garvey, an attorney, argued the broken taillight didn’t give the trooper “probable cause” for the stop. In a statement to the Journal News, Garvey said the case never should have been brought in the first place. Garvey’s been the head of Rockland’s GOP since 2014.
