Case Note & Summary
The case concerned the prosecution of K. N. Mehra, a cadet at the Indian Air Force Academy, Jodhpur, for theft of an aircraft under Section 378 of the Indian Penal Code. The appellant was undergoing training as a Navigator and was scheduled for a local training flight on a Dakota aircraft on the day of the incident. Instead, with the help of another cadet, P, who had been discharged for misconduct but possessed flying knowledge, the appellant took off in a different aircraft, a Harvard H.T. 822, without any authorisation. The flight was undertaken with the intention of going to Pakistan to seek employment, and the aircraft was force‑landed in Pakistan. Some days later, after contacting the Indian High Commission, both were arrested at Jodhpur upon their return and prosecuted for theft. The appellant contended that as a cadet under training he had implied consent to take an aircraft for flight, and therefore there was no ‘moving’ without consent and no dishonest intention. The prosecution argued that the act was wholly unauthorised, the purpose was personal, and the temporary deprivation of the Government’s use of the aircraft constituted theft. The Supreme Court held that since the flight was unauthorised, there could be no consent; from the outset the appellant’s purpose was unlawful—to go to Pakistan for employment—and not for training. The temporary use of the aircraft for his own purposes and the consequent deprivation of the owner’s use amounted to dishonest intention within the meaning of Sections 23 and 24 of the Indian Penal Code. The court clarified that under Section 378, a temporary retention of property with wrongful gain, or a temporary keeping out of property from the person legally entitled, may amount to theft. Consequently, the conviction for theft was upheld and the appeal dismissed.

Issue of Consideration
