How does Article 13 define custom or usage having the force of law?
Article 13 defines custom or usage having the force of law as any practice that has the legal effect of a formal law within the territory of India. This means that if a custom or usage is widely followed and accepted by people in a certain area, it can be considered as having the force of law even if there is no specific statute or rule enacted for it. However, this interpretation depends on the context provided and may vary in different situations.
