A legislation which confers on the executive or administrative authority an unguided and uncontrolled discretionary power in the matter of application of law violates which one of the following Articles of the Constitution of India?

A legislation that confers unguided and uncontrolled discretionary power on the executive or administrative authority violates Article 14 of the Constitution of India. Article 14 guarantees 'equality before the law' and 'equal protection of the laws'. The Supreme Court has repeatedly held that arbitrary power is destructive of the principle of equality. If the executive has unbridled discretion, it can lead to arbitrary and discriminatory actions, thereby negating the essence of equality enshrined in Article 14.
