K.N. Mehra v. State of Rajasthan

AIR 1957 SC 369

Facts

K.N. Mehra was a trainee cadet in the Indian Air Force.
Phillips, another cadet, had been discharged from service.
One morning, Mehra and Phillips took a Harvard aircraft from the Air Force flying school without permission.
The aircraft was not assigned to Mehra for that flight.
No authorised flight plan permitted them to take it outside the ordinary training area.
They flew toward Pakistan and ultimately made a forced landing there because of mechanical or fuel-related difficulty.
The surrounding circumstances indicated that Phillips intended to leave India and seek employment in Pakistan.
Mehra participated in taking and flying the aircraft.
He argued that the aircraft had not been taken dishonestly because:
he was an Air Force cadet authorised to fly aircraft generally;
the aircraft was not intended to be permanently appropriated;
it was eventually recovered.

Whether taking an aircraft for unauthorised temporary use amounted to theft.
Whether Mehra had the implied consent of the Air Force because he was a trainee pilot.
Whether an intention permanently to deprive the owner was necessary.

Theft requires dishonest moving of movable property from another’s possession without consent.
Consent may be express or implied, but it must cover the particular taking and purpose.
General permission to use property for official or training purposes does not authorise its use for a private and prohibited purpose.
Dishonest intention includes an intention to obtain wrongful gain or cause wrongful loss.
Permanent appropriation is not essential.
Depriving the owner of possession, use or control for a substantial unauthorised purpose may constitute wrongful loss.

The aircraft belonged to and remained in the possession of the Air Force.
Mehra’s position as a trainee did not give him unrestricted authority to select any aircraft and fly wherever he wished.
Permission to fly during authorised training was fundamentally different from permission to take an aircraft toward Pakistan with a discharged cadet.
The flight occurred without:
proper authorisation;
an approved destination;
an assigned training purpose.
The unusual timing and route, Phillips’s discharge and the movement toward Pakistan showed that the aircraft was being used for a private design.
The Air Force was deprived of its aircraft and exposed to:
loss of control;
risk of destruction;
possible permanent loss across an international border.
Even if Mehra hoped eventually to return the aircraft, its unauthorised use was capable of causing wrongful loss.
The Court therefore rejected the argument that temporary use could never be theft.
What mattered was the dishonest intention accompanying the movement, not whether the accused planned to sell the aircraft or retain it forever.
Mehra’s deliberate participation in the unauthorised departure established that intention.

The Supreme Court upheld the conviction for theft.
Mehra had no express or implied consent to take the aircraft for the journey toward Pakistan.
Temporary unauthorised use was sufficient because it caused wrongful loss to the Air Force and wrongful gain to the accused.
Use this case for: authorised access to property does not imply consent to dishonest private use, and temporary deprivation can constitute theft.
