Journalists and members of the public were denied access to the courtroom as Nasir El-Rufai appeared before the Federal High Court in Kaduna.
The restriction limited media coverage of the proceedings, and no official explanation was provided for the decision.
El-Rufai arrived at the court in a Hilux vehicle and was escorted inside by security personnel.
He was seen wearing a green babanriga and black cap, appearing calm as he greeted supporters outside the venue.
Security around the court premises was significantly increased, reflecting the sensitive nature of the case.
The situation has raised concerns about transparency as the high-profile trial continues to draw public attention.
