Thirty-three days after the election, the race for the Democratic district leader in Brooklyn’s 50th Assembly District came to an end. The city’s Board of Elections announced on Tuesday that the incumbent, Lincoln Restler, lost by 19 votes to a candidate backed by Assemblyman Vito J. Lopez, the former county party leader who stands accused of sexual harassment.
The winner, Chris Olechowski, 65, a Polish community leader and the chairman of the Community Board in Greenpoint, received 6,037 votes to Mr. Restler’s 6,018, a margin of 0.16 percent, the board said.
In 2010, Mr. Restler, then 26 years old, upset the county political establishment when he defeated Mr. Lopez’s handpicked candidate for the district, which includes Fort Greene, Greenpoint and Williamsburg.
A district leader, otherwise known as state committeeperson, is an unpaid, part-time elected official who serves a two-year term. The leader’s duties include endorsing candidates and helping select the county party’s leader.
When the votes were initially cast Sept. 13, Mr. Olechowski appeared to win by 136 votes. Because the margin of victory was less than a half a percentage point, a manual recount was required.
Mr. Olechowski’s victory appeared due at least in part to support in the district’s Hasidic precincts for Mr. Lopez. Turnout among Satmar Hasidim loyal to Mr. Lopez was enormous on Election Day.
Mr. Restler said that his campaign had calculated, based on the demographics of election districts, that more than 90 percent of the votes Mr. Olechowski received were cast in predominantly Hasidic neighborhoods. Outside those areas, Mr. Restler said, he, Mr. Restler, received 84 percent of the votes cast.
“In spite of this setback, the Brooklyn Reform Movement has grown in power and influence over the last few months,” Mr. Restler said by phone on Wednesday, “and we will continue to fight to ensure that every elected official is putting the best interests of our community first.”
Mr. Olechowski did not respond to an e-mail seeking comment.

An earlier version of this post mischaracterized a statement by the campaign of Lincoln Restler about Chris Olechowski’s performance in Hasidic neighborhoods. According to the Restler campaign, Mr. Olechowski garnered 90 percent of his votes in Hasidic neighborhoods; he did not receive 90 percent of the votes in those neighborhoods.
