The opposition United Party for National Development has pushed the filing of its petition before the Constitutional Court challenging the election of President Edgar Lungu to Friday.
It is understood the move is to mobilize its members to swarm the Supreme Court grounds.
President Lungu was on Monday declared winner after polling 1, 860, 877 while UPND's Hakainde Hichilema polled 1, 760, 347 votes translating into a 50.3% and 47.6% respectively.
An ensemble of 14 lawyers will be on the UPND case signalling how much importance the party attaches to their case.
The UPND alleges the vote was stolen from them through disparities in results transmitted at the polling centres and the national totalling centre being different with another claim of vote stuffing.
According to the amended constitution an aggrieved party has seven days within which to file their petition.
Once the petition has been filed the Constitutional Court will have 14 days within which to dispose of the matter during which time the Speaker of the National Assembly takes over as President in a caretaker role.
Ironically government has announced that the inauguration of the President elect will take place next Tuesday with preparations underway.
