The legal battle for immunity to prosecution by an informer who exposed criminal activities by members of the Central Intelligence Organisation (CIO) and senior police officers has been referred to the Constitutional Court.
The informer, Delish Nguwaya is accusing the police of deceiving him into giving self incriminating evidence on the grounds of immunity.
The police allegedly used the information to charge him together with three others.
Regional magistrate, Mr Themba Kuwanda ruled that the court was not in dispute that the information supplied by Nguwaya was used against him.
He said the information caused the set up of a taskforce by the CIO and the police to deal with the corruption.
The case has been postponed to the 1st of November pending the constitutional outcome. Nguwaya is jointly charged with Zano Vengayi, Clever Gadzikwa and Mbereki Mbizo Nyathi on allegations of extorting $20 000 from a chinese national, Baonig Guo.
