Johnston v Donaldson Coal Pty Limited & Ors [2023] NSWDC 250

Johnston v Donaldson Coal Pty Limited & Ors [2023] NSWDC 250

The Plaintiff failed to discharge the onus of proving that the 7 March 2011 incident, the nature and conditions of employment, or any work-related aggravation, acceleration, exacerbation or deterioration of disease caused his incapacity or the need for total left knee replacement. The Court accepted Dr Posel's orthopaedic evidence that the 2011 incident was a soft tissue injury with no ongoing sequelae, that pre-existing degenerative osteoarthritis was present, that there was no acute intra-articular injury or acceleration of degeneration, and that the Plaintiff had resumed and continued full duties. The unsupported opinions of Dr Harbury and Dr Hopcroft did not establish causation.
