4.  The applicants, who were born in 1984, 1987 and 1988 respectively, live in İstanbul. 5.

On the same day, the judge at the İstanbul Assize Court decided to restrict access to the investigation file, under Article 153 § 2 of the Code of Criminal Procedure (the “CCP”), Law no. 5271. The judge also decided to delay the second and third applicants’ right of access to their lawyer for twenty-four hours pursuant to section 10 of the Prevention of Terrorism Act (Law no. 3713), which was in force at the material time. 7.
