Judge Meyer Joffe will inform the High Court in Johannesburg on Friday on whether he will recuse himself from hearing the corruption case of former top cop Jackie Selebi.

"I'd like to thank counsel. I'm sure it wasn't easy to argue. It certainly wasn't easy to listen to," said Joffe before adjourning court until 11.30am on Friday.

On Thursday Joffe heard argument from both counsel over the bid to have him replaced for alleged perceived bias against Selebi.

The State opposed the application brought by the defence, saying their argument was weak.

"There is just no reason for the court to recuse itself," said prosecutor Gerrie Nel.

However, defence lawyer Jaap Cilliers detailed incidents he said Selebi perceived as showing pro-State bias through a "hostile" and "rude manner" in which Joffe at times dealt with the defence team.

If Joffe decides to recuse himself, the trial will have to start from scratch with a new presiding officer.

If he stays and court proceedings resume, State witness Glenn Agliotti will continue with his cross-examination.

Selebi is facing a charge of corruption and another of defeating the ends of justice in connection with at least R1.2-million he allegedly received from convicted drug trafficker Agliotti and others in return for favours.
