Which one of the following is not a correct statement with reference to the Constitution of India ?

Statement 1 is incorrect because the 'Right to Education' was inserted into the Constitution as Article 21A by the Eighty-Sixth (86th) Amendment Act, 2002, not the Eighty-Fifth Amendment. The 85th Amendment (2001) dealt with consequential seniority for SC/ST government servants. Statement 2 is correct as Article 22 provides protection against arrest and specifically regulates preventive detention laws. Statement 3 is correct because the Right to Constitutional Remedies (Article 32) is located within Part III of the Constitution [3]. Statement 4 is correct because the High Court's writ jurisdiction under Article 226 is wider than the Supreme Court's under Article 32; while the Supreme Court can only issue writs for Fundamental Rights, High Courts can issue them for Fundamental Rights and 'any other purpose' [2].
