Burundi's Constitutional Court on Friday ruled that the country's newly elected leader Evariste Ndayishimiye be rapidly sworn in following the sudden death of President Pierre Nkurunziza earlier this week.  

Ndayishimiye, who won the May 20 presidential poll, had been expected to take over the presidency from Nkurunziza in August when the latter's term ends. However, Nkurunziza's sudden death due to a heart attack on Monday created a possibility that the speaker of the Burundian National Assembly, Pascal Nyabenda, to become an interim leader before the swearing-in of Ndayishimiye in line with the Constitution. 

An extraordinary meeting of the council of ministers on Thursday decided to turn to the Constitutional Court to decide on the vacancy according to the Constitution.

"The Constitutional Court has noticed the vacancy. The referral is regular and competent," said president of the Constitutional Court Charles Ndagijimana in Bujumbura, commercial capital of Burundi. 

The court ruled that the country must "proceed, as soon as possible, with the swearing-in of the President-elect Evariste Ndayishimiye."  

The purpose of an interim president disappears due to the legal fact that a president-elect existed, Ndagijimana said. 
  
He also said the term of the president shall begin on the day on which he is sworn in and end on the day when his successor takes office.

Ndayishimiye, 52, won the election with 68.7 percent. Opposition claims of widespread fraud were dismissed by the Constitutional Court. He will serve a seven-year term in office and can renew the term once. 

Born in 1968 in central Burundi's Gitega province, Ndayishimiye held several senior positions in the government including minister of Home Affairs and Public Security, senior advisor in the office of the president in charge of military affairs and that in charge of civil affairs, successively, before being elected as secretary general of the ruling National Council for the Defense of Democracy-Forces for the Defense of Democracy (CNDD-FDD) in 2016. 

After the news of Nkurunziza's death, Ndayishimiye vowed to "continue his high-quality work that he has done for our country."  

The Burundian government has yet to announce a date for Nkurunziza's funeral, but is marking a seven-day period of national mourning, during which it has banned music in bars, nightclubs and karaoke, a statement said Thursday.
