There are a number of examples in the reported cases of the courts looking askance at employers seeking to disclaim obviously unreasonable terms and to sever out reasonable terms in restraint provisions contained in the relevant employment contract. The cases were reviewed by Dodds-Streeton J (as she then was) in I.F. Asia Pacific Pty Ltd v Galbally.[14] In that case, Dodds-Streeton J accepted that there is 'a strictly circumscribed role for severance in the context of employee restraint covenants.'[15] Her Honour described the accepted approach to severance in a restraint of trade context as a 'narrow approach'. In doing so, her Honour accepted the classic statement by Younger LJ in Attwood v Lamont.[16] Younger LJ expressed the narrow approach in the following way:
The learned judges of the Divisional Court, I think, took the view that ... severance always was permissible when it could be effectively accomplished by the action of a blue pencil. I do not agree. The doctrine of severance has not, I think, gone further than to make it permissible in a case where the covenant is not really a single covenant but is in effect a combination of several distinct covenants. In that case and where the severance can be carried out without the addition or alteration of a word, it is permissible. But in that case only.[17]
The covenant in Attwood v Lamont sought to restrain the employee being in any way concerned in any of the trades or businesses conducted by the employer, being 'the trade or business of a tailor, dressmaker, general draper, milliner, hatter, haberdasher, gentlemen's, ladies' or children's outfitter'. This was a description of all of the businesses conducted by the employer. However, the employee did not work in all of those businesses. He worked only in the tailoring department. In these circumstances, the employer sought to have the court sever from the restraint clause all reference to trades or businesses other than that of a tailor. The Divisional Court agreed that this could be done by a process of severance. The Court of Appeal allowed the appeal. As a matter of construction of the restraint clause, it was held that there was 'in truth but one covenant for the protection of the respondent's entire business, and not several covenants for the protection of his several businesses'.[18] In reaching this conclusion, and insisting upon a narrow approach to severance in the context of restraint of trade clauses, Younger LJ referred to the statement of Lord Moulton in Mason's Case that severance:
ought only to be done in cases where the part so enforceable is clearly severable, and even so only in cases where the excess is of trivial importance, or merely technical, and not a part of the main purport and substance of the clause. It would in my opinion be pessimi exempli if, when an employer had extracted a covenant deliberately framed in unreasonably wide terms, the Courts were to come to his assistance and, by applying their ingenuity and knowledge of the law, carve out of this void covenant the maximum of what he might validly have required. It must be remembered that the real sanction at the back of these covenants is the terror and expense of litigation, in which the servant is usually at a great disadvantage, in view of the longer purse of his master.[19]
In I.F. Asia Pacific v Galbally,[20] Dodds-Streeton J echoed Lord Moulton's words in determining that severance was not appropriate in the case before her. Her Honour stated that the narrow approach propounded by Younger LJ in Attwood v Lamont:
cautions against curial disentanglement of unreasonably wide clauses, recognising that they may act in terrorem by exposing employees to the threat of litigation. Undue judicial readiness to save such clauses by severance reduces the sanction of invalidity otherwise applicable to employers who attempt to impose unjustifiably wide restraints.[21]
