President Kgalema Motlanthe has not yet made a decision on who should replace axed National Director of Public Prosecutions Vusi Pikoli, his spokesman said on Wednesday.

"There has been no decision yet," Thabo Masebe said.

Meanwhile, Pikoli's lawyer Aslam Moosajee was waiting for the legal processes to be complied with after he served papers on Motlanthe challenging his client's dismissal last week.

At the same time, he is poised to launch an interdict on behalf of Pikoli if the president goes ahead and appoints someone else.

He also served papers on the Speaker of the National Assembly and the Chair of the National Council of Provinces, who managed the votes in Parliament to confirm Motlanthe's decision to fire him.

Pikoli wants the president's decision to be reviewed, set aside and declared invalid.

He lost his job after Motlanthe said an inquiry into his fitness to hold office found that he did not appreciate national security issues.

Advocate Mokotedi Mpshe is acting as prosecutions head for the division, which currently includes investigations against African National Congress president Jacob Zuma and National Police Commissioner Jackie Selebi in its caseload.
