The Supreme Court on Monday indefinitely delayed a vote for Liberia's new president, ordering the electoral commission to resolve an opposition party's complaint of electoral fraud before a runoff vote can be held.

The decision throws Liberia's first democratic transition in seven decades into uncertainty a day ahead of what was to have been the final round of voting to pick between former international footballer George Weah and incumbent vice-president Joseph Boakai.

Supreme Court Chief Justice Francis Korkpor said the National Elections Commission (NEC) was prohibited "from conducting the runoff election until the complaint filed by the petitioners is investigated," referring to the opposition Liberty Party.

But they must now await the result of an ongoing NEC complaint by a party neither belong to, as well as any Supreme Court appeal, which could take weeks.

The case was brought by Liberty Party presidential candidate Charles Brumksine, who came third on October 10 and has alleged ballot stuffing and false voter registration cards marred the election.

- Waiting game -

Liberia's constitution sets out a legal maximum of 30 days following the lodging of a complaint by the NEC, meaning the body has until November 22 to resolve the Liberty Party's case, which was brought on October 23.

From then, the party has a week to appeal, and the Supreme Court a week to decide on the appeal. The court also has the power to call new elections within 60 days if it decides to nullify the result.

"Liberty Party has rested evidence fully and we, the National Elections Commission, will now take the stand. So in a matter of days, we hope that there can be some conclusion to the investigation," said Musa Dean, a lawyer with the commission.

Africa's first elected female leader, the Nobel laureate Ellen Johnson Sirleaf, is stepping down after two terms spent transitioning her nation out of a long civil war, and the vote was seen as a marker of stability to buttress a fragile peace that has held since 2003.

- 'Contrary to the rules' -

The court found on Monday that the NEC had acted contrary to the law in declaring Weah and Boakai the top two candidates following an October 10 first round election while a question mark over the validity of the votes was pending.

"By setting a date and proceeding to conduct a runoff election without first clearing the complaint of the petitioners which alleged gross irregularities and fraud, the NEC was proceeding contrary to rules which are to be adhered to at all times," Korkpor said.

The court urged the commission to hear the Liberty Party's complaint and resolve it with "urgent attention", given the "critical" nature of the presidential vote.

"The efforts to disenfranchise voters and undermine Liberia's democracy were grave enough to warrant intervention from the Supreme Court, and we are glad that after listening to our case and reviewing the indisputable evidence, the court agrees," said Liberty Party chairman Benjamin Sanvee, celebrating the ruling.

Liberia is no stranger to disputed election results: Weah's CDC party challenged but ultimately accepted the results of presidential votes in 2005 and 2011.

His party said it welcomed a chance to "look into the issues," but said the result nonetheless had been in Weah's favour.

"We think the will of the Liberian people was clear in that election that is it favoured the CDC," Phil Tarpeh Dixon, a CDC lawyer, told AFP.

The court case comes at a tense moment in Liberian politics, as Brumskine and Boakai have both accused Sirleaf of "interference" in the elections and of secretly supporting Weah over her own vice-president, claims she has strongly denied.

A Supreme Court press officer told AFP that unidentified individuals pelted stones on Sunday night at the home of judge Sie-A-Nyene Yuoh but maintained the court "cannot and will not be coerced or intimidated."
