The magistrate was expected to read the judgment in an open court under a tent but suddenly changed his mind and decided to do it inside a courtroom, where he announced the postponement.
On his way to the courtroom from his chambers, a police officer carried the file for him. Magistrates are usually not accorded such treatment and security.
For the fourth time, a court postponed judgment in the trial of three suspects accused of masterminding the 2013 Westgate Mall terror attack that left 67 people dead.
The verdict on whether the three are guilty of terror charges is expected Wednesday.
