By striking down an Assam-specific law that has been in force for over 20 years, the Supreme Court today put a question mark over lakhs of Muslims who could be suspected to have illegally migrated from Bangladesh since 1971.The scrapping of the Illegal Migrants (Determination by Tribunals) Act 1983 has also come as a political bombshell in the run-up to the Assembly elections next year in the two big states bordering Bangladesh, Assam and West Bengal.The apex court declared the IMDT Act ‘‘unconstitutional’’ despite the endorsement of that law by the current regimes at the Centre and in the states of Assam and West Bengal.In fact, the UPA Government at the Centre and the Congress Government of Assam had reversed the positions taken in the matter by their predecessors, the NDA and AGP Governments, respectively.The Left Front Governmnt in West Bengal had on its part intervened in favour of the IMDT Act even though the law was confined to Assam.Not surprisingly, today’s judgment evoked a guarded response from the Congress and Left while the BJP and VHP celebrated it as a vindication of their long-standing campaign against Bangladeshi migrants.A three-judge bench headed by Chief Justice of India R C Lahoti unanimously struck down the IMDT Act on a petition filed by AGP leader Sarbananda Sonowal. So what happens now to the Bangladeshi migrants in Assam
