Ideology of the Islamic State of Iraq and the Levant considers secular law followers as true believers and that includes the Saudi government and all twelve judges in the court system as well.
Following Salafi-Wahhabi tradition, ISIL condemns the followers of secular law as disbelievers, putting the current Saudi government in that category. According to The Economist, dissidents in the ISIL capital of Raqqa reported (in 2014) that "all 12 of the judges who now run its court system ... are Saudis".
