Contracts of employment: Confidentiality clause valid

In Norbrook Laboratories Ltd v Smyth 30.9.86 High Court (Northern Ireland) the High Court in Northern Ireland holds that a restrictive covenant which was signed by an employee in the course of employment was binding in law. The court further holds that the confidentiality clause should not be regarded as void for being in restraint of trade even though the restriction was world-wide and was to last for one year after the employment ended.
