"Emmerson Dambudzo Mnangagwa is duly declared the victor of the presidential elections held on the 30th of July 2018", Malaba said in his ruling.
Zimbabwe's main opposition leader on Saturday rejected a court ruling that confirmed President Emmerson Mnangagwa as victor of the July 30 presidential vote and said he had a legitimate claim to lead the country.
The poll petition was triggered by Alliance leader Nelson Chamisa's electoral defeat to President Emmerson Mnangagwa in the July 30 elections.
Zimbabwe's president-elect Emmerson Mnangagwa has taken to Twitter, to express his thoughts on the Constitutional Court ruling that dismissed the opposition Movement for Democratic Change (MDC) Alliance's claims of electoral fraud.
On August 2, Zec announced that Mnangagwa had garnered 50.8 percent of the total vote, with Chamisa taking 44.3 percent.
An hour before the ruling, Chamisa's spokesperson Nkululeko Sibanda suggested there was collusion between Zanu PF and the judiciary, as images on social media indicated that preparations for Mnangagwa's inauguration were well under way long before the ruling.
The Zimbabwe opposition figure who was denied asylum in Zambia and then charged at home with inciting public violence says "the struggle continues" after the constitutional court upheld President Emmerson Mnangagwa's narrow election win.
The elections were largely judged to be free of the violence which characterised previous elections in Zimbabwe.
In a first for the country, the proceedings were broadcast live on state television.

Chamisa acknowledged that, with the Constitutional Court's decision, "the legal route has come to a dead end".
"Specifically, we are going to show Mr. Mnangagwa and the world that the peaceful masses have rejected him", it read.
The president, after the verdict, called for peace and unity.
The Zimbabwean constitution specifies that for a presidential candidate to get a mandate to form a government, he or she must get at least 50% plus one of the vote.
He also said that if the opposition had requested a re-count of the vote it would have provided "a clear and indisputable picture of the outcome of the election".
The 94-year-old Mugabe was forced from office by a military takeover last year after almost 40 years in power, surrendering the presidency to Mnangagwa, his vice president.
Chamisa insists he won more than two-thirds of the vote.
The ruling of the court will be final and can not be appealed.
The unanimous decision that the opposition failed to produce "sufficient and credible evidence" means the inauguration will be held within 48 hours as Zimbabwe moves into a new era after Robert Mugabe's 37-year rule.
