Which of the following Articles of the Constitution operates as an *absolute* limitation upon the legislative power, in the sense that no exception or restriction is constitutionally permitted?

1. The ICSI text classifies certain Articles — **15, 17, 18, 20 and 24** — as 'absolute limitations upon the legislative power'. 2. Article 17 declares that 'Untouchability is abolished and its practice in any form is forbidden'; the enforcement of any disability arising out of untouchability is an offence punishable by law. There is **no permissible restriction or exception** carved into the text. 3. Article 19 freedoms are explicitly subject to reasonable restrictions under clauses (2)-(6). Article 22 itself sets out the conditions for preventive detention. Article 25 is subject to public order, morality and health. So those three are *not* absolute limitations. 4. The discipline being tested is the distinction between rights that are absolute against the legislature and rights that admit of constitutionally specified restrictions. _Source: ICSI CS Executive — Lesson 2, classification of Fundamental Rights, p. 29 ¶5._
