Question

Following is/are the requisites for a valid custom:

• A. Reasonableness
• B. Certainty and inconsistency
• C. Conformity with international law
• D. All of the above are requisites for a valid custom

Hint:

Valid custom must be ancient, certain, reasonable, and not opposed to statute/public policy.

Answer 1

The Correct Option is A

Step 1: Essentials of a valid custom (domestic law context).
Common essentials:
1. Antiquity (long usage)
2. Continuous and uniform practice
3. Certainty
4. Reasonableness
5. Conformity with statute law (not necessarily international law)
Step 2: Why others are wrong.
(b) “Certainty and inconsistency” is wrong — must be certain and consistent, not inconsistent.
(c) Conformity with international law is not a general requirement for domestic custom validity.
(d) Wrong because (b) and (c) are not correct requisites. \[ \boxed{(a)} \]
