Running as an independent, Georgescu is due to face liberal Elena Lasconi of the Save Romania Union (USR) on Sunday.
The court ordered a ballot recount Thursday over allegations that votes from one candidate, who dropped out a week before the election and threw his support behind Lasconi, were illegally transferred to her on election night.
Constitutional Court President Marian Enache said all nine justices on the court had agreed the allegation was unfounded and that the election results were thus valid.
While the recount did lead to slightly different vote totals for some candidates, the variations were not due to electoral fraud, Enache told reporters after a court session Monday.
The court’s decision to certify the results will restore some stability to Romania’s electoral process, in which the country is undergoing three elections (one parliamentary and two presidential rounds) take place within three weeks.
Had the court annulled the election it would have inflamed an already tense political situation, with many Romanians suspecting the country’s mainstream parties, which don’t have a candidate in the runoff, of trying to manipulate the outcome.
