The Supreme Court on Sunday night cleared the way for Avi Nissankoren to take the helm of the Histadrut Labor Federation, the country's largest union.In November, sitting Histadrut chairman Ofer Eini announced that he would resign the position he held for five years, annointing the Trade Union division's Nissankoren, as his preferred successor. With Eini's backing, Nissankoren had little trouble winning the support of the Histadrut leadership, obviating the need for a general election from the Histadrut's membership.Labor MK Eitan Cabel, who had battled Eini for the position in previous elections and hoped to throw his hat in the ring once again, took the Histadrut to court in December for circumventing a general election. When the Tel Aviv District Court ruled in favor of the Histadrut, Eini appealed, forcing a delay in the succession process at the union. Eini, who had intended to step down come February, decided to stay on board until the matter was cleared up in order to avoid a leadership vacuum. On Sunday, the Supreme Court dismissed Cabel's appeal, effectively clearing the way for Nissankoren to take up the mantle of the Histadrut leadership.
