Ground 3
19 This ground goes to whether compensation was not payable in respect of the worker's injury or death because it was caused by an intentional self-inflicted injury (s14(3) of the Act). Holdlen Pty Ltd v Walsh (2000) 19 NSWCCR 629 was an appeal from awards to the child of a deceased worker who had been injured at work and then committed suicide. Giles JA, in a decision with which both Meagher and Heydon JJA agreed, after referring to several English decisions including Marriott v Maltby Main Colliery Co Ltd (1920) 13 BWCC 353 at 359 which involved inquiries into the deceased worker's sanity, said at 635 [24]:
"… the inquiry into sanity was regarded as going to causation. Suicide, an intentional act of the worker, would break the chain of causation between the injury and the death unless the worker's mental state, described as insanity, was such that it should not be regarded as an intentional act. Hence the other requirements that the suicide be the result of the insanity and the insanity be the result of the injury, because without them even the 'unintentional' act would break the causal chain."
20 Giles JA referred to Church v Dugdale & Adams Ltd (1929) 22 BWCC 444 where Lord Hanworth MR described Marriott as "the locus classicus for … the guidance to be found in these cases" and said at 449:
"The upshot of all that is, that when one turns to see the facts of the case before the Court it is necessary to find not merely that there has been suicide, not merely at the time of the suicide that there was some depression and some delusions, but you must find that the condition of the man was such that the accident disabled him from exercising a judgment, and in that sense caused the accident. If you find merely that in consequence of the accident he is brooding in fear of poverty, or in distress, or in a mental condition which is consistent with the condition of a person not suffering from an accident, there you do not find and are not entitled to draw the inference that his mind has become unhinged so as to dethrone his power of volition, and in that sense there is no proof and no necessary connection between the accident and the suicide."
21 Giles JA continued at 636:
"26 A test of whether the worker was 'suffering from mental derangement sufficient to dethrone his power of volition" was affirmed in Parry v English Steel Corporation Ltd (1939) 32 BWCC 272 in which it was said at 275 that it was beyond question that there could be "such a destruction of volition as may cause the suicide to be referable to what caused the destruction of the volition - possibly the accident - even though there is no insanity in the legal sense'."
22 At 637-8 Giles JA said that s14(3) of the Act was not easy to construe:
"The word 'injury', used twice, must be used in two different senses, notwithstanding that it is defined in s4. On one view, the first injury is a physical condition short of death caused by an injury as defined ['personal injury arising out of or in the course of employment', s4(a)], and the injury as defined must not be an intentional self-inflicted injury. On this construction s14(3) says nothing about death by suicide in a case such as the present, because it could apply only if the 14 November 1994 injury was an intentional self-inflicted injury. On another view, the first injury is an injury as defined and the second injury is an act of injuring; this appears to have been the view taken in Bird v Australian Iron & Steel Pty Ltd [1979] 53 WCA (NSW) 227. On this construction s14(3) can arguably apply to death by suicide in a case such as the present, because the death of a worker by suicide could be said to be caused by an intentional self-inflicted act of injuring."
23 A little later on, after referring to March v E & MH Stramare Pty Ltd (1991) 171 CLR 506, Giles JA said at 639 (37):
"The test of dethronement of the power of volition has been adopted, and it does not necessarily turn on insanity. The law recognises in contexts not involving insanity that the will may be overborne or subjected to such influences that, although an act is deliberate, it is not regarded as the actor's intentional act."
24 His Honour referred to what Lord Simon said in Director of Public Prosecutions for Northern Ireland v Lynch [1975] AC 653 at 695 about duress as deflecting, without destroying, the will of one of the contracting parties and to the definition of duress by Lord Scarman in Universe Tankships Inc of Monrovia v International Transport Workers Federation [1983] 1 AC 366 at 400 as pressure amounting to the compulsion of the will of the victim. Lord Scarman said that the classic case of duress is "not the lack of will to submit but the victim's intentional submission arising from the realisation that there is no other practical choice open to him." Giles JA said at 639 [37]:
"Suicide, while deliberate, may often (but not always) be the product of a will so overborne or influenced by the worker's circumstances that it should not be regarded as an intentional act breaking the chain of causation. Insanity is not a necessary step to this result."
