Parties campaigning for the voting rights of South Africans living abroad should have their cases heard in a single proceeding, the AParty said on Tuesday.

The party has called for all South Africans living abroad, irrespective of the duration of their stay there, to be given the opportunity to vote at South African missions.

"The Chief Justice of the Constitutional Court received an urgent request from the Independent Electoral Commission's attorneys this afternoon to consolidate all submissions regarding the Expat Vote issue in a single proceeding," AParty chairman Anthony Penderis said on Tuesday.

He said his party, along with the FF Plus, the Democratic Alliance and Kwame Onkgopotse Moloko and 11 others have already filed applications in various courts in the country.

"The IEC's attorneys state that it is highly likely that cases brought before the various divisions of the High Court will be referred to the Constitutional Court because it is in the public interest that the expat vote applications are not dragged over several months" he said.

IEC spokeswoman Kate Bapela could not confirm or deny that the IEC had filed an urgent application with the Constitutional Court.

"We are not in the habit of discussing matters that are before the court. If the matter is sub judice then you should get such information from court records," she said.

On Monday, the Pretoria High Court ruled that South Africans living abroad be allowed to vote in the upcoming general elections.

This after the FF Plus brought the application on behalf of a South African school teacher living in the United Kingdom.

The court ruled that the Electoral Act "limited" the casting of votes to people temporarily living abroad.

It referred the judgment to the Constitutional Court for confirmation.
