Later Act when to be used to interpret an earlier

Except as a parliamentary exposition, subsequent Acts are not to be relied on as an aid to the construction of prior unambiguous Acts. A later statute may not be referred to, to interpret the clear terms of an earlier Act, which the later Act does not amend even though both Acts are to be construed as one, unless the later Act expressly interpret the earlier Act, but if the earlier Act is ambiguous, the later Act may throw light on it, as where a particular construction of the earlier Act will render the later incorporated Act ineffectual . An Act of parliament does not alter the law by merely, betraying an erroneous opinion of it . Nalanikani v. l,T Commissioner Bombay , AIR 1967 SC 193 L (1966) SCJ 41. To the same effect are the observations made earlier by the Supreme Court of India in Shiv Shankar Shukla v. A.D. Divekar, 1957 SCR 121 at p. 140. In this part the term "the building" means a building in respect of which a three years licence has been or may be granted as provided in rule 18. Film shall be stored :- (i) in a storage shed constructed of suitable uninflammable materials; the doors and ventilators may be of wood, and shall open outwards, or (ii) in a tent, placed on private ground and separated by a distance of not less than 25 feet from any dwelling house, other building, highway, street, or public place.
