Schabir Shaik's lawyers have appealed to the Constitutional Court to set all his convictions aside.
The Durban businessman's lawyer, Reeves Parsee, confirmed yesterday that the appeal had been lodged with the highest court in the land.
When asked which convictions would be challenged, Parsee said: "All of them."
Issues that form part of the argument of Shaik's lawyers include unfair prosecution, constitutional issues and irregular seizure of documents.
Shaik was found guilty of corruption and sentenced to 15 years in jail. - Waghied Misbach and Sapa
