Factors Affecting Liability II
Duress and Necessity

 
Necessity

A defence involving a plea by an accused that he or she was compelled to commit a criminal act by some imminent threat or danger present

Necessity operates where circumstances (natural or human threats) pressure the accused & induce him or her to break the law to avoid even more dire consequences

Three elements of the defence of necessity (Loughnan [1981])

i) the criminal act must be done in order to avoid consequences so serious that they would have inflicted irreparable evil on the accused or others
ii) the threat or danger must be imminent & immediate
iii) the response must be proportionate to the threat or danger & reasonable in the circumstances

Dudley & Stephens (1884) (Queen’s Bench)

Facts: Three men & a boy were cast away in an open boat for 18 days after their yacht had been shipwrecked. Weakened by starvation, Dudley & Stephens suggested to the third man that they should kill & eat the boy. He dissented, but they killed the boy anyway. All three men fed upon the body of the boy, only to be rescued four days after the killing. On charges for murder, they raised the defence of necessity.

Decision: The jury found that the men probably would have died had they not eaten the boy, that the boy probably would have died before them, & that at the time of the killing there was probably no appreciable way of saving life without taking this course of action.

Per Coleridge LJ: Necessity was no justification for murder in these circumstances.

Public policy reasons  - it would be a great departure from morality & the principle would be dangerous because of the difficulty of measuring necessity & of selecting a victim

Consent, either directly or through the casting of lots, may have been a defence (unlikely now because of R v Brown [1993] – group of sadomasochists, cannot consent to harm above that which is more than trifling or transient)

Southwark v Williams [1971]

Facts: Defendants were in desperate need of housing & began squatting in some empty houses owned by the local council. They raised the defence of necessity.
Decision: Defendants failed. Per Denning L: “If hunger were once allowed to be an excuse for stealing, it would open a way through which all kinds of disorder and lawlessness would pass. So here. If homelessness were once admitted as a defence to trespass, no one’s house could be safe.”

Per Edmund-Davies: “The law regards with deepest suspicion any remedies of self-help, and permits those remedies to be resorted to only in very special circumstances…necessity can very easily become simply a mask for anarchy.”

Loughnan [1981]

Facts: A prisoner was convicted of escaping from prison & pleaded necessity on the grounds that he was told by another prisoner that he would be killed that night.

Decision: Three elements to the defence of necessity (see above)

Rogers (1996)

Decision: If the accused honestly believed on reasonable grounds that escape from prison was necessary in order to avoid threatened death or serious injury, then he would have an excuse.

White (1987)

Facts: A motorist was charged with speeding when he was trying to get his sick son medical treatment.
Decision: He succeeded.
Necessity is available as a defence to a strict liability statutory offence.

Re: A (Children) (2000) (English Court of Appeal)

Facts: A health authority & its doctors wanted clarification of their position in separating Siamese twins where one of the children would not survive the operation. The parents refused to consent to such an operation.

Decision: Per Ward LJ: “…the defence is available only if, from an objective standpoint, the accused can be said to be acting reasonably and proportionately in order to avoid the threat of serious injury…the issue should be left (where available) to the jury who should be asked these two questions: first, was the accused, or may he have been, impelled to act as he did because as a result of what he believed to be the situation, he had good cause to fear that otherwise death or serious physical injury would result; second, if so would a sober person of reasonable firmness, sharing the characteristics of the accused, have responded to that situation by acting as the accused acted. If the answer to both those questions was ‘yes’ then the jury should acquit; the defence of necessity would have been established.”

Crimes Act s82

Whosoever, being a woman with child, unlawfully administers to herself any drug or noxious thing; or unlawfully uses any instrument or other means, with intent in any such case to procure her miscarriage, shall be liable to penal servitude for ten years.

Wald (1971)

Decision: There is no legal wrongdoing where a miscarriage is produced by someone with an honest belief on reasonable grounds that termination of pregnancy was necessary to preserve the health and well-being of the woman during the currency of the pregnancy.

CES v Superclinics [1995] (NSWCA)

Facts: A woman, CES, claimed damages in tort against several doctors & Superclinics (the medical centre where the doctors worked) for failing to diagnose her pregnancy, & thus preventing her from obtaining a lawful abortion.

Trial judge held that any proposed termination would have been unlawful according to the principles stated in Wald & ss 82 or 83 of the Crimes Act, because her pregnancy was no danger to her physical or mental health. She appealed.

Decision: Appeal was allowed. Per Kirby: Expanded the Wald test from an honest & reasonable belief that the danger to the woman’s mental health may arise “at some time during the currency of the pregnancy” to include “after the birth of the child”.

Per Priestley JA: There was a real possibility that had the plaintiff been told of her pregnancy in time, she would have been advised that she was able to have a lawful abortion & would have had the abortion performed.

Policy reasons why courts have traditionally limited the application of the defence of necessity
