Exceptions

Intervening cause is typically an exception to the eggshell skull rule. If an injury is not immediate, but a separate situation agitates the injury (such as the injured party being involved in a vehicular collision while being taken to a hospital), the tortfeasor is not liable under common law in Australia (see Haber v Walker, and Mahoney v Kruschich Demolitions). In Haber v Walker it was held that a plaintiff will not be liable for a novus actus interveniens (intervening act) if the chain of causation was broken by a voluntary, human act or, an independent event, which in conjunction with the wrongful act, was so unlikely as to be termed a coincidence. In Mahoney v Kruschich Demolitions the plaintiff, Glogovic, was injured while working on the demolition of a power house for the respondent. While being treated for his injuries, his injuries were exacerbated by the negligent medical treatment of the appellant, Mahony. It was held that there was no novus actus as a result of medical treatment of injuries caused by the defendant's negligence, unless such treatment is inexcusably bad or completely outside the bounds of what a reputable medical practitioner might prescribe.
