Jackie Selebi's legal team is poised to ask the Johannesburg high court to drop all charges against their client.
This they will do after the state closes its case against the former police chief today.
His counsel, Advocate Jaap Cilliers, said he would first ask for time to prepare for his application.
Also, Judge Meyer Joffe ruled that transcripts of the testimony by former intelligence chief Barry Gilder be made public.
Gilder earlier testified about a draft intelligence report containing a paragraph about allegedly untoward payments Selebi received from slain mining magnate Brett Kebble.
Selebi's legal team had asked that everything be made public to allay speculation that he was being shielded by the government.
"Our concern is that our client has been an object of huge media speculation that the government is assisting him," Cilliers said.
The 2004 report suggests that businessman Jurgen Kogl, who was seen to be sympathetic to President Jacob Zuma, was "gathering information on supposed illegal activities by Selebi" in an effort to discredit then-president Thabo Mbeki.
"He claims that the national commissioner received large sums of money from the Kebbles emanating from questionable business deals concluded on his behalf," the report says.
Selebi denied seeing or knowing about the existence of the report.
However, Selebi's former friend and state witness Glenn Agliotti, a convicted drug trafficker, said he was shown the report by the former commissioner when he was allegedly paying him in return for immunity from arrest.
Agliotti testified that he was approached by the Kebbles to be the go-between for them and Selebi. He said he was given millions of rands by the family to give to Selebi, who would ensure they were protected from the law.
He said he paid Selebi about R1million and spent hundreds of thousands taking his family on shopping sprees and dinners.
Selebi has pleaded not guilty to charges of corruption and defeating the ends of justice.
