"Government spokesperson Lambert Mende said" The court is independent, both of us and the African Union.

At a meeting on Thursday in Addis Ababa, AU heads of state and government agreed to send a high-level delegation to Kinshasa help solve the crisis.
AU commission chief Moussa Faki Mahamat and Rwanda President Paul Kagame, currently the AU chairperson, are expected to fly in on Monday.
The summit also said there were "serious doubts" about the provisional results of the vote.

On January 10, DRC's electoral commission declared opposition leader Felix Tshisekedi the provisional winner of the December 30 vote with 38.57 percent against Fayulu's 34.8%.
But Fayulu declared the result to be an "electoral coup" forged by Tshisekedi and Kabila, and filed with the Constitutional Court a day later.
He claims he won with 61% of the vote.

The dispute has raised fears that the political crisis began when Kabila refused to step down at the end of his constitutional term in office two years ago, could turn into a bloodbath.
The vast and chronically unstable country lived through the two regional wars in 1996-97 and 1998-2003, and the previous two elections in 2006 and 2011, were marred by bloody clashes.

The Southern African Development Community (SADC), a bloc that includes Angola and South Africa, initially called for a recount and a unity government.
But in a later communique, instead of calling on Congolese politicians to "address any electoral grievances in line with the Democratic Republic of Congo's Constitution and relevant electoral laws".
Kagame's visit as part of the AU delegation could complicated matters, analysts say.
Rwanda backed the 1997 ouster of dictator Mobutu Sese Seko by Kabila's father, Laurent-Desire Kabila, but then changed allies. Sporadic clashes occurred last year on the border between the two neighbors.
