The Supreme Court has stayed the prosecution of UPND president Hakainde Hichilema before the magistrate court.
This follows an application by Hichilema's lawyer to transfer the matter to the High Court for trial as a reasonable court to determine constitutional issues that may arise.
Hichilema is accused of spreading false information likely to cause alarm.
The stay of execution means that the trial cannot proceed in the Lusaka magistrate court tomorrow until preliminary issues are determined in the Supreme Court.
The two parties will now appear for inter-party hearing on January 24.
It is alleged that Hichilema claimed that the PF government wanted to send youths to train as militias in Sudan.
