The MDC Alliance on Friday filed its court papers at the Constitutional Court to challenge the outcome of Zimbabwe's general elections held on July 30.
"It's amusing that Chamisa (MDC Alliance presidential candidate Nelson) entered an election wanting to win only".
His MDC Alliance party say the vote was marred by "mammoth theft and fraud", but the electoral commission has said there was "no skulduggery".
According to his draft order, Mr Chamisa is seeking the nullification of President Mnangagwa's victory and wants the court to declare him the victor.
Zimbabwe's justice minister Ziyambi Ziyambi has told state media Zanu PF was keenly following events across as preparations for Mnangagwa's inauguration tentatively set for August 12 are already in motion. "All proceedings are suspended pending the determination of the Constitutional Court".
"If the MDC Alliance files before the deadline, then the Constitutional Court will have the final decision to stop the inauguration or allow it to be conducted within a period of 14 days". If it does this successfully, the court could order a recount or nullify the result altogether.
Global monitors largely praised the conduct of the election itself, although European Union observers said that Mnangagwa, a former long-time Mugabe ally, benefitted from an "un-level playing field" and some voter intimidation.

Spencer Drago was called for holding, though, setting up third-and-18. Mayfield closed 11-of-20 for 212 yards with two scores on the night.
"We have a good case and cause!" he tweeted shortly after filing the challenge.
The election, the first since the army's removal of 94-year-old ex-president Robert Mugabe last November, passed off relatively smoothly but its aftermath revealed the deep rifts in Zimbabwean society and the instinctive heavy-handedness of the security forces.
Mr Mnangagwa has appealed for peace and promised an independent investigation into the post-election violence.
In the announced results President Mnangagwa garnered 50,8 percent against Mr Chamisa's 44, 3 percent to secure victory in the presidential poll.
The constitution requires a losing presidential candidate to file any challenge within seven days of a victor being declared.
The Court has ordered that Mr. Biti is to surrender passport & title deeds and report twice a week to police, not to interfere with witnesses or address political gatherings.
