The Court observed that while ordinary principles of contract permit termination when one party becomes unable to perform, in employment law the question remains whether it was fair in the circumstances for the employer to exercise that election. The fact that an employee is not at fault for their inability to perform is a consideration that should properly be brought to account in assessing fairness. The Court noted that whether imprisonment constitutes 'incapacity' or 'absenteeism' under section 188(1) of the Labour Relations Act may be a matter of debate, but suggested that incapacity might include imprisonment. However, the Court indicated that the categorization was not material in this case as the arbitrator would have reached the same conclusion regardless of the categorization. The Court acknowledged the dilemma faced by employers when they do not know when an employee will be capable of resuming duties, but emphasized that there is no universal answer and each case depends on its particular facts. Nugent JA noted that he expressed no view on whether he would have reached the same conclusion as the arbitrator, emphasizing that this was not the relevant question on review.
