The binding legal principles established are: (1) The Labour Court's jurisdiction under section 77(3) of the Basic Conditions of Employment Act does not extend to delictual claims for unlawful interference with employment contracts, as such claims do not constitute 'matters concerning a contract of employment' but rather require determination of elements of delictual liability (harm, wrongful conduct, causation, and fault) which are not primarily concerned with enforcement of contractual obligations. (2) In restraint of trade cases involving training and skills acquisition, an employer's protectable interest is limited to proprietary know-how, specific product knowledge, and customer relationships developed during employment - it does not extend to general industry skills acquired through training. (3) A restraint of trade will only be enforced to the extent reasonably necessary to protect legitimate protectable interests, and courts will limit both the scope and duration of restraints to achieve an appropriate balance between protecting the employer's interests and allowing the employee to pursue their vocation.
