As per case facts, two Nigerian nationals appealed against the dismissal of their Writ Petition by a Single Judge, where they sought release from detention and visa extension. They were ... subjected to Movement Restriction Orders based on allegations of drug peddling (unsubstantiated), possession of a fake passport by one appellant, and failure to register by the other, as well as being found with an impersonating individual. The Single Judge deemed procedural fairness irrelevant since their visas were already cancelled and due to expire soon. The question arose whether the Central Government's absolute power to expel foreigners must still adhere to procedural fairness, especially regarding informing them of deportation reasons and providing an opportunity for representation, even if their visas were cancelled. Finally, the High Court answered that while some procedural fairness is generally expected, it was unnecessary to examine further as the appellants' visas would have expired anyway. Foreigners have no inherent right to a visa or its renewal, and the State holds an unfettered sovereign right to deny or cancel visas without requiring an explanation. The Central Government's power to expel foreigners is absolute and unlimited, subject only to Article 21 but not Article 19 of the Constitution. Thus, the appeal was dismissed.
