“Nowhere but Everywhere”: The Principle of Legality and the Complexities of Judicial Discretion in Iran

Abstract To comply with Shiʿi theological-jurisprudential justifications and dogmatic traditions, the Iranian postrevolutionary legal system formally enshrined the principle of legality of crime and punishment within the Iranian Constitution and important legal provisions. Despite this formal entrenchment and codification of its criminal law, which together act as a legal constraint on the traditionally excessive power of Muslim judges, the Iranian theocratic system has exempted religious sins from this principle by blurring the distinction between crime and sin and criminalizing certain sinful acts with unclear language. These two legal mechanisms not only violate the principle of legality and amplify legal uncertainty, but their reference to Sharia law also binds the fate of the accused more tightly to the discretion of the judge than to the letter of the law. Consequently, the religiopolitical predilections of judges have become a determining factor in findings of criminal responsibility and imposition of punishment on citizens.
