X and Y are about to travel from Jammu Tawi to Delhi by the same train. Y has two tickets from…

Y came into possession of X's ticket lawfully, because X voluntarily handed it to him for checking; Y's later dishonest retention of it for his own use is "Criminal Misappropriation" under section 403 of the Indian Penal Code. There is no theft because Y did not take the ticket out of X's possession without his consent, no extortion because X was not put in fear, and no cheating because X was not deceived into handing over the ticket.

Current law: dishonest misappropriation of property is now section 314 of the Bharatiya Nyaya Sanhita, 2023.
