JUDGMENT

THAKKAR, J.:— A Seven-Judge Constitution Bench decision in Hari Singhs case (1973) 1 SCR 515 : (AIR 1972 SC 2205) upholding the constitutionality of the Public Premises (Eviction of Unauthorized Occupants) Act, 1971 [Act 40 of 1971] (Act) notwithstanding, the petitioner has renewed the challenge by way of this petition under Art. 32 of the Constitution of India. Of course the epicentre of the present challenge has shifted and is now located in the plea that Parliament does not have the legislative competence to legislate on the subject of the impugned legislation which dimension was not in focus in Hari Singhs case.

2. The petitioner was allotted a piece of land on licence by the respondents. The licence was cancelled on the allegation that petitioner had illegally made encroachment on further land and had illegally raised a structure on the land granted on licence. The respondent terminated the licence. Proceedings were initiated against the petitioner under the Act. The competent authority passed an order of eviction against the petitioner. Petitioners appeal to the appellate authority under the Act was dismissed. The High Court also dismissed the petition preferred by the petitioner. This court refused to grant special leave and dismissed petitioners Special Leave Petition. Petitioner even so filed a Civil Suit which came to be dismissed for default of appearance. Meanwhile the petitioner had approached this court by way of a Special Leave Petition against an interlocutory order passed by the Civil Court. The said special leave petition also came to be dismissed for default of appearance. And thereafter the present Writ Petition has been instituted under Art. 32 of the Constitution of India. In the petition as originally framed the constitutionality of the Act was not challenged. The said challenge was incorporated by amending the petition. When the matter came up for hearing this Court issued a Rule Nisi limited to the question of constitutionality of the Act as is evident from the relevant part of the order extracted hereiribelow : -

"Application for amendment allowed. Rule Nisi on the question of constitutional validity of the Public Premises (Eviction of Unauthorised Occupants) Act, 1971. Notice to the Attorney General and the Union of India ordered."

3. Thus the only question before the court presently is as regards the constitutional validity of the Act. The scheme of the Act as set out in Hari Singhs case (AIR 1972 SC 2205 at p. 2208) is as under :-

"The scheme of the 1971 Act is that it confers power on Estate Officer to issue notice to persons who are in unauthorised occupation of any public premises to show cause why an order of eviction should not be made. Unauthorised occupation under the Act in relation to any public premises means the occupation by any person of the public premises without authority for such occupation, and includes the continuance in occupation by any person of the public premises after the authority (whether by way of grant or any other mode of transfer) under which he was allowed to occupy the premises has expired or has been determined for any reason whatsoever. Premises are defined to mean any land or any building or part of a building and includes the garden, grounds and outhouses, appertaining to such building or part of a building and fitting affixed to such building or part of a building for the more beneficial enjoyment thereof. Public premises means any premises belonging to or taken on lease or requisitioned by, or on behalf of the Central Government as enumerated in Section 2(e) of the Act. The notice to show cause against order of eviction shall specify the grounds on which the order of eviction is proposed to be made. The Estate Officers under the Act are appointed by the Central Government. The Estate Officers are Gazetted Officers or officers of equivalent rank. Corporate authority under the Act means any company or Corporation or any committee or the Authority as mentio
