Martin Fayulu, who was next in the presidential election of the Democratic Republic of Congo last month, has appealed to the country's constitutional court to cancel the preliminary result.
"The request seeks cancellation of the result declaring Felix Tshisekedi's president, his lawyer Feli Ekombe told reporters outside court Saturday.
Fayula's camp has accused the declared winner, opposition candidate Felix Tshisekedi, of making a secret deal with outgoing president Joseph Kabila.
"You can't portray the results behind closed doors," Fayulu said in front of a follower of his supporters.
"I hope the Constitutional Court will call the electoral commission to tell the ballot papers. "They are false, portrayed, nothing to do with the truth. The truth must come from the narrative of the ballot."
Tshisekedi's victory shocked pollen strokes and was immediately challenged by the opposition and Western forces.
The influential Catholic Church also rejected the official result based on numbers 40,000-strong observer teams.
"The results published do not match the data collected by our own observation mission," said Marcel Utembi, head of the National Episcopal Conference of Congo (CENCO).
"We have a recommendation: To publish all records and minutes from the counties and polling stations as soon as possible."
& # 39; All eyes on court & # 39;
Congo has been tense over the past few days with increasing violence across the country, creating fear of a collapse of law and order, similar to the violence that erupted in the Central African country after the 2006 and 201
Al Jazeera's Haru Mutasa, who reported from the DRC capital Kinshasa, said the judges were expected to meet early next week to review the alleged evidence that Fayulu has won the election.
"If the judges feel that there is no case, they will throw the case out. Felix Tshisekedi is declared the elected president and will be sworn in on January 18.
" If that happens, some people fear that Fayulu could tell her followers to walk on the streets and there could be an escalation violence. in Kinshasa, but elsewhere around the country. So many call many people on the Congolese people to remain calm.
"But all eyes will be in court when they meet, and many people will wonder how independent they should be".
