The South Giza Criminal Court adjourned the trial of dozens of senior intelligence officers accused of ordering the destruction of important documents to 16 April.
The court made the ruling Thursday after Defense Minister Abdel Fattah al-Sisi was unable to testify a second time citing the deteriorating security situation.
Former Interior Ministers Mansour al-Essawy and Mahmoud Wagdy were also unavailable.
Prosecutors claim Major General Hassan Abdel Rahman and 40 other members of the now defunct State Security Investigation Services bureau destroyed numerous SSIS documents before the body was shut down after the January 25 uprising.
As public employees, the prosecution claims the defendants sought to sabotage national security through their actions.
