Employment – Contract of employment. A clause relied on by the employee in her contract did prohibit shareholdings in any business carried on in competition with the former employer and was impermissibly wide and in restraint of trade, unless it could be severed in some way. The Supreme Court held that applying the severance principle, namely that the words were capable of being removed without the need to add to or modify the wording of the remainder and the removal would not generate any major change in the overall effect of the restraints, the words should be severed and removed.
