Cape Town - Agang SA MP Mike Tshisonga is the party's new acting president, deputy president Andries Tlouamma said on Thursday.
“The Western Cape High Court has interdicted the so-called reconstituted NEC and ruled that it is not the legitimate NEC of Agang,” Tlouamma said.
“The court ruled that the legitimate NEC is the one that held a meeting in Alexandra on June 29, 2014.”
The court confirmed Tshisonga as the party's acting president, he said.
Party spokesman John McConnachie said the interdict banned anyone from speaking on behalf of Agang SA, except the national executive committee (NEC) recognised by the court.
“The interdict is very wide. None of us are allowed to speak on behalf of the party. We have basically been gagged,” he said.
A meeting would be held on Thursday evening to map a way forward.
“We will issue statements as individuals after the meeting, because we are all still members of Agang SA.”
The party had been marred by internal divisions. On Friday, it said a reconstituted NEC had issued disciplinary notices to Tshisonga and Tlouamma and others, setting out the grounds for disciplinary action.
One faction held an NEC meeting in Alexandra, Johannesburg, on June 29 at which it was decided that its former leader, Mamphela Ramphele, was not fit for the position.
The group adopted a motion of no confidence in her and questioned her leadership style.
She was subsequently suspended, but a group supporting Ramphele retaliated by expelling those who had attended the meeting.
On July 8, Ramphele announced she had decided to leave party politics to focus on working within civil society.
Ramphele launched Agang SA last year.
In the May 7 general elections, Agang SA received 52 50 votes, 0.28 percent of the 18 654 771 votes cast, which earned it two seats in Parliament.
