Reasonable Forseeability in Australian Tort Law

“The touchstone of liability remains reasonableness of conduct”

The unique importance and influence of ‘reasonable foreseeability’ in common law is reflected in its ubiquitous presence in all areas of negligence, having become the essential thread of fabric or ‘touchstone' upon which the tort of negligence and liability has been constructed. The historical and theoretical development of modern tort law, largely spurred on by the social, economic, political and cultural changes of the last century, has revolutionised the way in which ‘reasonable foreseeability’ has been approached by the judicial system. The evolution of acknowledgement that negligent actions gave rise to injury has bred new classes of personal injury, such as pure mental harm and pure economic loss, previously unclassified or ignored by the courts. The specialised nature of these injuries and the court’s inclination towards maintaining the basic doctrines of tort law has diminished the value of ‘reasonable foreseeability’ as an adequate and exclusive measure in determining the existence of a duty of care. Accordingly, this essay will address the fallibility of ‘reasonable foreseeability’ in determining the existence of a duty of care in relations to actions for pure mental injury and pure economic loss and consequently discuss the relevant adequacy and need for extra legal tests within these domains.

The Civil Liability Act’s (CLA) distinct definition of pure mental injury as separate from consequential harm reflects the legal system’s affirmation that ‘something more’ than the test of reasonable foreseeability is required within this area. The judicial dichotomy between physical and psychiatric injuries reflects the historical and political context surrounding this issue, in particular the court’s scepticism regarding the legitimacy of nervous shock as class of injury. Such scepticism can be traced back to the court’s original feminist interpretation of psychiatric injury in addition to their perpetual ‘fear of fakery’ in regards to fraudulent claims for psychiatric injury. Indeed the evidential difficulties in proving psychiatric harm are starkly contrasted to the relatively easy identification of physical injury, a reality which pioneered the historical distinction between the two. Whilst such misgivings have lessened recently, s31 of the CLA is proof that such judicial hesitance still exists regarding the validity of certain illnesses. The purpose of this section as ‘something more’ is embodied by Howie’s situation in the fact scenario, as the medically unrecognised nature of Capgras Syndrome nullified his claim. This is indicative of the court’s desire to prevent a ‘floodgate’ of claims associated with fraudulent or imaginary illnesses succeeding and undermining the doctrine of tort law. Conversely the successfulness of Priscilla’s claim in regards to s 31 indicates that whilst these extra tests do limit the scope of liability, they still perform their perfunctory duty in compensating rightful victims.

Whilst the guiding principle behind the court’s inclusion of extra legal tests for pure mental injury remains firmly rooted in its fear of fraudulence, these tests also reflect the concern of indeterminacy as encapsulated by s30 and s32 of the CLA. These respective sections further reduce the scope of claim for pure mental injury by underlining the importance of proximity and relationship as governing factors in actions for pure mental injury. Ultimately the shortcomings of reasonable foreseeability in inadequately eliminating fraudulence and indeterminacy is the basis upon which the courts have decided that ‘something more’ is required in actions for pure mental ...
