A disciplinary hearing for Julio Galeano, the East Hampton Village police officer who allegedly used a house on Talmage Lane for a romantic visit with a fellow member of the force without its owner’s knowledge, is scheduled for tomorrow at 10:30 a.m. at the Emergency Services Building. John G. Callahan, an attorney who was appointed by the village board as an independent arbitrator to hear the charges against Mr. Galeano, will listen to comments and testimony. After the hearing, which may take more than one session, Mr. Callahan will recommend appropriate action to the board. Whether the hearing will be open to the public is up to Mr. Galeano, according to Rebecca Molinaro, the village administrator; as of yesterday he had not made a decision. The alleged incident, on Dec. 30, involved Mr. Galeano and Jennifer Rosa, a traffic control officer. Ms. Rosa, according to a fellow T.C.O., knew where a key to the house was because she had previously worked there as a cleaner. The owner of the house had invited guests for the New Year’s holiday. He was not there when they arrived and discovered the pair. They called the police. Ms. Rosa was fired from the force in January. Mr. Galeano’s badge and gun were confiscated, and he was suspended with pay, per the collective bargaining agreement between the village and the Police Benevolent Association. He has denied the charges through the P.B.A. Village Police Chief Gerard Larsen brought disciplinary charges against Mr. Galeano on Feb. 11. Ten days later the village board adopted new legislation on police discipline that does away with the arbitration procedures previously required and provides for dismissal as an option. Also that day, the board unanimously voted to suspend Mr. Galeano for 30 days without pay. The P.B.A. then sought a temporary restraining order in Suffolk County Supreme Court to prevent the new local law from taking effect, with an attorney for the union calling it a breach of contract. The petition was denied, and Ms. Molinaro said Tuesday that the P.B.A. has withdrawn its challenge. Kevin Duchemin, a village police sergeant and president of the P.B.A., did not return a call seeking comment. Mr. Galeano’s 30-day suspension expired on March 21. He was returned to the payroll, but was required to stay at home, according to Chief Larsen. A native of Columbia, Mr. Galeano is the only Latino officer on the force. In 2013, the department recognized him for his role in the arrest and conviction the year before of a man accused of having sexual relations with a child.
