The Supreme Court today sought a response from the Centre on petitions challenging the constitutional validity of the amendments made in the Unlawful Activities (Prevention) Act.<br />''<br />''The petition filed by Association for Protection of Civil Rights said, the amendments infringed upon the fundamental right to reputation and dignity under Article 21 of the Constitution, without substantive and procedural due process.<br />''<br />''It added that condemning a person unheard on a mere belief of the government was unreasonable, unjust, unfair, excessive, disproportionate and violated the due process. A bench comprising Chief Justice Ranjan Gogoi and Justice Ashok Bhushan issued the notices.<br />''<br />''The Unlawful Activities (Prevention) Act was passed by Parliament on August 2 and it received the President's assent on August 9. The amended act allows the Centre to designate individuals as terrorists and seize their properties. The act also provides for putting a travel ban on such individuals once they are declared as terrorists.<br />
