[1] The appeal before us turns on one aspect of unfair dismissal law. In this jurisdiction, the remedy for unfair dismissal is codified, inter alia, in s 20 of the Industrial Relations Act 1967 ('the Act'). The focal point of the appeal turns on whether the Industrial Court, in the exercise of its statutory function to adjudicate on a representation of dismissal without just cause or excuse under s 20 of the Act, may consider matters or issues which did not comprise basis/reason for the dismissal when the employer made the decision to dismiss, but which the employer seeks to put forward post-dismissal, in the Industrial Court, to justify its earlier decision to dismiss the workman.
