Haitian hip-hop star Wyclef Jean has said he will appeal against a ruling that he cannot run in Haiti's presidential election.
Haiti's electoral commission said that Mr Jean was ineligible to stand as the Haitian constitution requires candidates to have lived in the country for five years prior to an election.
The 40-year-old singer lives in the US.
But he argues that his role as a roving ambassador for Haiti since 2007 exempts him from the residency requirement.
The country is still recovering from January's earthquake, which killed an estimated 230,000 people and left more than one million homeless.
Following the ruling on Friday, Mr Jean issued a statement saying he respectfully disagreed with the electoral panel's decision, but accepted it and urged his supporters to do the same.
However, on Sunday Mr Jean told reporters that he was refusing to give up and that he would challenge the decision in court.
Speaking to the Associated Press news agency from his house in the Haitian town of Croix des Bouquet, Mr Jean said he had documentation about his candidacy "which shows everything is correct" and that he and his aides "feel that what is going on here has everything to do with Haitian politics".
In a message on the micro-blogging site Twitter, Mr Jean said: "Tomorrow our lawyers are appealing the decision of the CEP. We have met all the requirements set by the laws. And the law must be respected."
