The petition was filed at 12 midday, the party said in a statement on Wednesday, December 30.
It was filed on behalf of former president John Dramani Mahama by his lawyers.
The statement issued by NDC’s General Secretary, Johnson Asiedu Nketia, said: “The Petition was filed pursuant to the party‘s audit of the 2020 Presidential results and extensive consultations with the National Executive Committee and Council of Elders of the party.
“The Petition details serious violations of the 1992 Constitution by the Electoral Commission and its Chairperson and Returning Officer for the Presidential Election, Mrs. Jean Adukwei Mensa in the conduct of their constitutional and legal responsibilities.
“It seeks among others, a declaration from the Supreme Court to the effect that, the purported declaration of the results of the 2020 Presidential Election on the 9th day of December 2020 is unconstitutional, null and void and of no effect whatsoever.”
Apropos the petition, Mr. Dramani Mahama will be addressing the nation at 8:00 pm.
The NDC rejected the results of the elections a day after they were declared by the Electoral Commission, Ghana (EC).
Mrs. Mensa had announced incumbent Nana Addo Dankwa Akufo-Addo as the winner of the polls with 6,730,587 votes, representing 51.3 percent.
But at the press conference to express his dissent to the declared results, Ghana’s president between 2012 and 2017 described Mrs. Mensa’s action as illegality, then announcing his intention to take the legal course, aside from other actions, to reverse the declaration.
“On account of this, my party is confident that what has happened is a violation of the law. It is a violation of due process and, therefore, tantamount to illegality.
“It is also a violation of an understanding we hold dear in this country, and understanding that this is not dictatorship or a monarchy run by a single family for the benefit of a family.
“Ghana belongs to the people of Ghana, all of the people of Ghana.”
Supporters of the party, prior to the legal action, have staged numerous demonstrations across the nation to register their repugnance to the outcome of the elections.
