The pre-trial conference of two men accused of murdering honeymooner Anni Dewani resumes in the High Court in Cape Town on Friday.
Xolile Mngeni and Mziwamadoda Qwabe face charges of kidnapping, robbery with aggravating circumstances, murder, and two counts relating to the illegal possession of a firearm and ammunition.
At their last appearance, on May 11, Mngeni's lawyer Matthews Dayimani said his client would undergo brain scans to determine whether he was psychologically fit to stand trial.
"These are the final scans. We have to make our decision quickly before the end of the month. Time is running out, so to speak," he said.
Qwabe had run out of funds for legal representation and intended applying for legal aid.
Dewani, 28, was shot dead in an apparent car hijacking while she and her husband were on honeymoon in Cape Town in November 2010.
An order for her husband's extradition was signed by the United Kingdom secretary of state in September 2011, but Britain's High Court temporarily halted the extradition on mental health grounds, saying it would be "unjust and oppressive".
Shrien Dewani is being treated in a mental health hospital in his hometown of Bristol, western England.
He will be extradited to South Africa as soon as he is fit enough.
