Izhar Ahmad Khan v Union of India

Facts

The petitioners claimed to be Indian citizens but had obtained Pakistani passports. The Central Government, acting under Section 9(2) of the Citizenship Act, 1955 read with Rule 3 of Schedule III to the Citizenship Rules, 1956, determined that they had voluntarily acquired Pakistani citizenship, treating the grant of a Pakistani passport as conclusive proof of voluntary acquisition. The petitioners challenged Rule 3 as ultra vires, contending it dealt with the substantive question of loss of citizenship rather than mere evidence.

Issues

• Whether Rule 3 of Schedule III, prescribing that the obtaining of a foreign passport is conclusive proof of voluntary acquisition of foreign citizenship, is a rule of evidence or a rule of substantive law.
• Whether such a conclusive (irrebuttable) presumption is within the rule-making power conferred by Section 9(2) of the Citizenship Act, 1955.
• Whether the rule was constitutionally valid having regard to Article 11 and the petitioners' claimed rights.

Arguments

The petitioners argued that a rule converting a relevant fact into conclusive proof of the extinction of citizenship operates on substantive rights and so falls outside the power to make rules of evidence; merely holding a passport does not necessarily establish voluntary acquisition of foreign citizenship. The Union argued that Rule 3 is a genuine rule of evidence because a passport bears an inherent and rational probative connection to the fact of voluntary acquisition of citizenship, and that conclusive presumptions have always been part of Indian evidence law.

Held

The Supreme Court, by majority (Gajendragadkar J. writing), dismissed the petitions and upheld Rule 3 and Section 9(2). It held that Section 4 of the Evidence Act, 1872 has, since 1872, recognised rules creating presumptions that 'may be drawn', that 'shall be drawn' subject to rebuttal, and that 'shall be conclusively drawn'; hence a rule of conclusive proof is squarely a rule of evidence. Where fact A is inherently relevant to proving fact B, a rule directing that proof of A shall be conclusive proof of B remains a rule of evidence even though irrebuttable, and the grant of a Pakistani passport was inherently relevant to the question of voluntary acquisition of Pakistani citizenship. It was therefore not a rule of substantive law merely because it foreclosed rebuttal. Sarkar and Das Gupta JJ. differed in reasoning, taking the view that the true test is whether the rule creates, modifies or extinguishes a right (substantive) or merely regulates proof (evidence).

Ratio decidendi

A statutory rule that makes one fact conclusive proof of another is a rule of evidence, not of substantive law, provided the basic fact has an inherent and rational probative bearing on the presumed fact; irrebuttability alone does not convert a presumption into substantive law. Conclusive presumptions are an established species of evidence law under Section 4 of the Evidence Act.

Significance

A landmark on the nature of conclusive presumptions and the distinction between rules of evidence and substantive law, frequently cited on the scope of 'conclusive proof' under Section 4 of the Evidence Act. Under the Bharatiya Sakshya Adhiniyam, 2023 the same three-fold scheme of presumptions ('may presume', 'shall presume' and 'conclusive proof') is carried forward in the definitions in Section 2(1), so the reasoning continues to govern how conclusive presumptions are classified and applied.
