“22. This Act confers wide ranging powers to deal with all foreigners or with respect to any particular foreigner or any prescribed class or description of foreigner for prohibiting, regulating or restricting their or his entry into India or their presence or continued presence including their arrest, detention and confinement. The most important provision is Section 9 which casts the burden of proving that a person is not a foreigner or is not a foreigner of such particular class or description, as the case may be, shall lie upon such person. Therefore, where an order made under the Foreigners Act is challenged and a question arises whether the person against whom the order has been made is a foreigner or not, the burden of proving that he is not a foreigner is upon such a person. In Union of India v. Ghaus Mohd. the Chief Commissioner of Delhi served an order on Ghaus Mohammad to leave India within three days as he was a Pakistani national. He challenged the order before the High Court which set aside the order by observing that there must be prima facie material on the basis of which the authority can proceed to pass an order under Section 3(2)(c) of the Foreigners Act, 1946. In appeal the Constitution Bench reversed the judgment of the High Court holding that onus of showing that he is not a foreigner was upon the respondent.”
