Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is duress of circumstances?

    Model answer

    Duress of circumstances is a defence where the defendant commits an offence because objective circumstances, rather than a person's demand, threatened death or serious injury.

  2. 2

    How does duress of circumstances differ from duress by threats?

    Model answer

    In duress by threats a person demands that the defendant commit the offence, while in duress of circumstances the pressure comes from the situation itself.

  3. 3

    In which kind of case did duress of circumstances first develop?

    Model answer

    It emerged in driving cases, where defendants drove dangerously or while disqualified in order to escape an immediate threat of violence.

  4. 4

    How does R v Martin (1989) illustrate duress of circumstances?

    Model answer

    A disqualified driver drove his stepson to work because his wife threatened suicide if he did not, and the defence was left to the jury.

  5. 5

    What did R v Pommell (1995) establish about the scope of the defence?

    Model answer

    The Court of Appeal held that duress of circumstances is available generally, to all offences except murder, attempted murder and treason, rather than only to road traffic offences.

  6. 6

    What test applies to duress of circumstances?

    Model answer

    The same two-stage test as duress by threats: a reasonable belief in a threat of death or serious injury, and a response that a sober person of reasonable firmness would have made.
