Mubaiwa, through her lawyer Ms Beatrice Mtetwa, indicated she was supposed to undergo a medical operation for injuries sustained in the Bulawayo blast at White City Stadium in 2018.
According to the state media,the operation had been scheduled for June since it was assumed the assault trial would be over by then.
Mubaiwa appeared in court before regional magistrate Mr Trynois Utahwashe. The State consented to the trial running from July 27 to 30.
Mr Muchemwa said: “Your Worship, this matter was supposed to be coming for trial today, but some members of the public are not yet allowed to come to court.
The trial of Marry Mubaiwa on assault charges had to be postponed yesterday as some witnesses were observing the lockdown in their rural homes and cannot travel.
