The Montgomery County police union last night abandoned plans for a censure vote against Police Chief Donald E. Brooks, saying the union had won a "clear-cut victory" in negotiating written commitments from county officials on a list of 11 concerns.

It was the second time in five weeks that Fraternal Order of Police Lodge 35 backed away from a vote of no-confidence in Brooks, who was appointed two years ago by County Executive Sidney Kramer after the death of Bernard Crooke.

The 800-member union threatened its first censure vote July 10, but postponed the move after Kramer agreed to purchase 66 new take-home police cruisers for $1.3 million and initiate "good-faith" negotiations on other complaints.

Last night, union officials declared a "clear-cut victory as big as this year's Super Bowl" after voting down a motion for a censure vote. About 130 union members attended last night's meeting at the Marriott Hotel in Gaithersburg.

"It's a dead issue now," said union spokesman Don McClure. The threat of a proposed censure vote "got some attention and response to our concerns," McClure said. "The county gave {police officers} everything they wanted because the censure vote would have been a tremendous embarrassment."

McClure acknowledged the union maximized its political leverage by calling for the no-confidence vote weeks before the Sept. 11 Democratic primary. "Because of the pressure brought to bear . . . it's a clear-cut gain for the FOP," he said.

Also last night, the union voted to remain neutral in the county executive primary between Kramer and Neal Potter, a 20-year veteran of the County Council.

The voice vote concerning Brooks came after about 90 minutes of sometimes loud discussions at the meeting, which was closed to the news media.

According to the union, the county has given "written commitments" to buy the new police cruisers and inspect and repair nearly 2,000 mobile and portable radios that officers said frequently break down.

In addition, the union said the county has agreed to allow officers to purchase their own 9mm semiautomatic handguns and allow four disabled officers to remain on the force another year. A decision on whether the county will pay for the handguns will be included in contract negotiations scheduled to start in November, McClure said.

The union said Kramer and Brooks also agreed not to oppose a union proposal to relax current policies on second jobs for police officers. Union leaders intend to ask the County Council to repeal some restrictions on moonlighting.

In an unexpected move, the union last night voted to allow selection of a civilian arbitrator on police trial boards that review disciplinary actions against officers. Such boards now consist of three officers -- one chosen by the accused officer, one by the chief and a third by the union. Under the alternative system approved last night, the chief would select an officer, the FOP would select one, and the third member -- a labor arbitrator who would head the panel -- would be agreed on by the accused, the chief and the union.

In July, Prince George's County Executive Parris N. Glendening, under pressure stemming from police brutality charges, announced he would support the addition of a civilian on police tribunals.
