Puronlal no operation and may for the present discussion be Union Lalchanpal v. of India kept aside." His Lordship was considering the Act of 1950 previous S. K. Dtul. to the amendments subsequently made therein from 1951 onward, and the observations appear to establish the. following three points: first, clause ( 4) of Art. 22, put in affirmative form, has reference to a law which provides for preventive detention and authorises detention for a period longer than three months; second, the expression 'such detention' has again reference to such a law providing for detention beyond a period of three months; and lastly, cl. (4) of Art. 22 had no application to the Act of 1950 as it then stood. We shall presently show that the first and the second points do not really support the appellant's contention and the last had particular reference toss. 9 and 12 of the Act of 1950, as it then stood. The appellant has, however, pointed 9ut that under the Act as it now stands, every order of detention has to be placed before the Advisory Board (s. 9 of the Act) and the Advisory Board has to report ab6ut ev~ry order of detention (s. 10 of tI:ie Act). Though under s. llA of the Act the maximum period for which any person may be detained in pursuance of a detention order which has been confirmed under s. 11, is twelve months from the date of detention, the Act now contains no provisions as to the circumstances under which, or the class or classes of cases in which, a person may be detained for a period longer than three months without obtaining the opinion of the Advisory Board; therefore, the argument of the appellant is that the last point made by the observation of Kania C.J. is no longer valid in view of the amendments made in the Act of 1950. We have proceeded. in this case on the footing that sub-cl. (a) of cl. (4) of Art. 22 applies to the Act as it stands after the amendments, and even on that footing there is, in our opinion, no inconsistency between that sub-clause and the impugned provisions of the Act, aa we shall presently explain.
