“We are conscious of the principle that the word ‘or’ is normally disjunctive and ‘and’ is normally conjunctive. However, there may be circumstances where these words are to be read as vice-versa to give effect to manifest intention of the Legislature as disclosed from the context.
Of course, these two words normally ‘or’ and ‘and’ are to be given their literal meaning in unless some other part of same Statute or the clear intention of it requires that to be done. However, wherever use of such a word, viz., ‘and’/’or’ produces unintelligible or absurd results, the Court has power to read the word ‘or’ as ‘and’ and vice-versa to give effect to the intention of the Legislature which is otherwise quite clear. This was so done R.M.D. Chamarbaugwala, (1957) 1 SCR 874.”
