PORT-AU-PRINCE, Haiti — An electoral tribunal in Haiti has rejected claims that massive voter fraud marred the November presidential election victory of first-time candidate Jovenel Moise, officials said Tuesday.

The judges found some irregularities but not enough to affect the outcome based on an analysis of 12 percent of the ballots, the Provisional Electoral Council said in a statement that cleared the way for Moise to be declared the winner.

Several rivals challenged the results, but the electoral judges said they found “there was no massive fraud,” according to the council.
