SARBANANDA SONOWAL vs UNION OF INDIA

The Supreme Court ruled that the Illegal Migrants (Determination by Tribunals) Act, 1983 is unconstitutional as it violates Article 14 of the Constitution, which guarantees equality before the law. The Court held that the Act discriminates against Indian citizens in Assam by making it difficult to detect and deport illegal migrants, thereby undermining the Foreigners Act, 1946. Consequently, the Court declared the IMDT Act and its associated rules as ultra vires, affirming that the Foreigners Act shall apply in Assam.
