Judgment :- Chelameswar, J. 1. Leave granted. 2. These two appeals are preferred against the final judgment dated 9th August 2007 passed by the Calcutta High Court in FMA No.206 of 2003 and order dated 30th August 2007 in Review Application bearing RVW No.2372 of 2007 dismissing the said review application filed by the appellant herein. 3. The facts leading to the instant litigation are as follows: 4. The appellant was initially detained by order dated 19.12.1974 under the provisions of the Maintenance of Internal Security Act, 1971 (since repealed) and later under the provisions of the Conservation of Foreign Exchange and Prevention of Smuggling Activities Act, 1974 (hereinafter referred to as the “COFEPOSA”) on the ground that he in collaboration with his brother, who was living in London at that point of time, was indulging in activities which are prejudicial to the conservation of foreign exchange. The appellant unsuccessfully challenged the detention order. He was eventually released in 1977. 5. While he was in custody, the second respondent issued a notice dated 4th March 1977 under section 6(1) of the Smugglers and Foreign Exchange Manipulators (Forefeiture of Property) Act, 1976 (hereinafter referred to as “the Act”) calling upon the appellant to explain the sources of his income out of which he had acquired the assets described in the schedule to the notice. Some correspondence ensued between the second respondent on one hand and the wife of the appellant and the appellant on the other hand, the details of which may not be necessary for the time being. 6. Eventually on 27th November 1989, the second respondent passed an order under section 7(1) of the Act forfeiting the properties mentioned in the schedule to the said order. 7. Aggrieved by the said order, an appeal was carried to the Appellate Tribunal constituted under section 12 of the Act. The appeal was partly allowed setting aside the forfeiture of two items of the properties. 8. Not satisfied with the Appellate Authority’s conclusion, the appellant challenged the same in writ petition No. C.O. No.10543 (W) of 1991 before the High Court of Calcutta. The appeal was partly allowed setting aside the forfeiture of two items of the properties. 8. Not satisfied with the Appellate Authority’s conclusion, the appellant challenged the same in writ petition No. C.O. No.10543 (W) of 1991 before the High Court of Calcutta. In the said writ petition, the appellant also prayed for two declarations – (1) that the Act is illegal and ultra vires the Constitution and (2) that the detention of the appellant under the COFEPOSA by the order dated 19th December 1974 was illegal and void – a collateral and second round of attack. 9. Learned Single Judge of the Calcutta High Court by an order dated 10th May 2002 partly allowed the writ petition holding that the forfeiture of the property by the second respondent as confirmed by the Appellate Tribunal was illegal on the ground that the notice under section 6(1) of the Act dated 4th March 1977 was not in accordance with the law as the notice did not contain the reasons which constituted the basis for the belief of the competent authority that the appellant illegally acquired the scheduled properties. 10. Aggrieved by the order of the learned Single Judge, the respondents herein carried the matter in appeal to the Division Bench. By the judgment under appeal, the appeal was allowed. 11. It appears from the judgment under appeal that though the appellant sought a declaration that the Act (SAFEMA) is unconstitutional, such a plea was not pressed before the learned Single Judge. [On perusal of the judgment and order of the Learned Single Judge it appears that although the vires of the said Act was under challenge the respondent No.1 only asked for cancellation of the order of detention issued under Section 3 of the COFEPOSA and the orders passed by the competent authority so merged in the appellate authority under section 6(1) of the SAFEMA as well as prayed for release of the properties confiscated by the appellate authority in terms of the order impugned therein.] 12. Before us, the appellant made three submissions – (1) that the notice issued under Section 6 of the Act is defective and therefore illegal as the notice did not contain the reasons which made the competent authority believe that the notice scheduled properties are illegally acquired properties. Before us, the appellant made three submissions – (1) that the notice issued under Section 6 of the Act is defective and therefore illegal as the notice did not contain the reasons which made the competent authority believe that the notice scheduled properties are illegally acquired properties. In other words, the reasons were not communicated to the appellant; (2) that the forfeiture, such as the one provided under the Act, is violative of Article 20 of the Constitution of India; and (3) in the alternative, it is argued – that the High Court failed to consider th
