Alleged "sex blogger" Juan Uys appeared briefly in the Cape Town Magistrate's Court on Monday on charges of theft and crimen injuria.
The crimen injuria complaint was laid by Cape Town mayoral committee member Simon Grindrod, who was at court to see the man who he says falsely accused him on the Internet of using the services of a male prostitute.
Magistrate Phindi Norman postponed both matters to August 20 and told Uys he was out on warning.
Speaking to reporters outside the court, Grindrod, who is also deputy president of the Independent Democrats, said he also intended to sue Uys, and had already consulted an advocate.
"This is a direct assault on my character, so I have a responsibility to challenge it," Grindrod said.
"It's not simply a case of 'this is your average political insult'.
But a cheerful Uys told Sapa that he intended to sue Grindrod for comments the politician had made about him.
"I'm going to do the same. I've already discussed it with my lawyers. I'm going to claim R12-million from him," Uys said.
He also said he intended to lay a crimen injuria complaint with Cape Town police against Grindrod over statements Grindrod had made to newspapers.
"I cannot just sit down and see someone tarnishing my name and leave it at that," he said.
Uys last week laid a complaint of intimidation against Grindrod at the Kroonstad police station, where he initially appeared on the theft charge.
The theft charge, which dates back to 2004, stems from a complaint laid by a man who paid money to attend a party which was to be arranged by Uys.
Uys, who at one time led the Gay and Lesbian Alliance, which he claimed was an organisation with thousands of members, has also been linked to "Neil Watson" who ran a website on crime in South Africa. - Sapa
