“Heathrow Airport Ltd applied for a wide-ranging injunction which, had they succeeded, could have banned five million people from the Piccadilly Line, large sections of the M4 and land surrounding Heathrow as well as the airport itself. It would have done so by making them subject to the provisions of the Protection from Harassment Act 1997.”
