The five Arbitrators who currently compose Tranche Alpha are SimonP, Raul654, Mackensen, Neutrality, and Fred Bauder. Raul654 was a candidate for reelection while Neutrality, Fred Bauder, Mackensen, and SimonP did not run.

The result of the election saw Newyorkbrad, FT2, FayssalF, Sam Blacketer, and Deskana named to Tranche Alpha. Flcelloguy was removed from Tranche Gamma due to inactivity; sitting arbitrator FloNight was moved from Tranche Beta to Gamma (effectively extending her original two-year term by one year); Thebainer, who placed sixth in the election, was named to the vacated seat in Tranche Beta. Flcelloguy is eligible to reclaim a seat in Tranche Gamma for the balance of his unexpired term, should he return to active editing, and would fill an "expansion seat".
