Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
The PAC under its new president, Letlapa Mphahlele, has endorsed the expulsion from its ranks of the party's former president, Motsoko Pheko.
Pheko holds the party's only seat in the national assembly.
Yesterday PAC spokesman Mudhini Maivha said the Eastern Cape had rejected Pheko's appeal against his expulsion.
The party expelled Pheko after accusing him of "mishandling" donations made to the party during his tenure.
A high court decision allowed Pheko to appeal against his expulsion.
Mphahlele subsequently wrote a letter to Pheko informing him that his appeal would be heard during the party's congress.
"The congress decided to reject Pheko's appeal and uphold the decision to expel him," Maivha said.
Yesterday Pheko told Sowetan that his legal representative had not been allowed to attend his appeal at the conference.
"What kind of justice is this? Just like before when I heard about my expulsion through the media," said Pheko.
Mphahlele was re-elected president, the new general secretary is Mfaeno Skwatsha and Andisa Mjali is his deputy. Frank Ngidi is the treasurer.
Another faction, known to be supporters of former PAC leader Clarence Makwetu, has said it does not recognise the conference.
The faction has announced that the "real PAC" conference will be held next month.
