"If it will not be possible to hold a trial before the period for which the plaintiff claims to be entitled to an injunction has expired, or substantially expired, it seems to me that justice requires some consideration as to whether the plaintiff would be likely to succeed at a trial. In those circumstances it is not enough to decide merely that there is a serious issue to be tried."
“12. I do not accept that the principle of preference of enforceability to unenforceability can be invoked in favour of any alternative legitimate construction since the ingenuity of business and their lawyers may assert that many a plausible construction is a "legitimate" construction. This principle used to be expressed in the maxim "verba ita sunt intelligenda ut res magis valeat quam pereat" and is now called "Saving the document" (see Chitty 32nd edition para 13084). But the principle can only go so far since one has to start with the language used by the parties; there must, in my view, be a genuine ambiguity before the principle can be invoked and I respectfully doubt whether Waller LJ meant, in the paragraph of Turner to which we were referred, to imply that ambiguity was not required. As Lord Hoffmann observed in BCCI v Ali[2002] 1 AC 251 para 39, when referring to the principle that parties are unlikely to have intended to agree to something unlawful or legally ineffective:- "But the primary source for understanding what the parties meant is their language interpreted in accordance with conventional usage."” "But the primary source for understanding what the parties meant is their language interpreted in accordance with conventional usage."”
“The law relating to restrictive covenants in the employment context was not in dispute, although at trial and again on appeal the parties were able to point to different aspects of the jurisprudence in support of their respective cases. I take the following general principles from the discussion of the subject to be found in Chitty on Contracts, 31st ed, at paras 16-105ff and in the jurisprudence there cited. (i) Post-termination restraints are enforceable, if reasonable, but covenants in employment contracts are viewed more jealously than in other more commercial contracts, such as those between a seller and a buyer. (ii) It is for the employer to show that a restraint is reasonable in the interests of the parties and in particular that it is designed for the protection of some proprietary interest of the employer for which the restraint is reasonably necessary. (iii) Customer lists and other such information about customers fall within such proprietary interests. (iv) Non-solicitation clauses are therefore more favourably looked upon than noncompetition clauses, for an employer is not entitled to protect himself against mere competition on the part of a former employee. (v) The question of reasonableness has to be asked as of the outset of the contract, looking forwards, as a matter of the covenant's meaning, and not in the light of matters that have subsequently taken place (save to the extent that those throw any general light on what might have been fairly contemplated on a reasonable view of the clause's meaning). (vi) In that context, the validity of a clause is not to be tested by hypothetical matters which could fall within the clause's meaning as a matter of language, if such matters would be improbable or fall outside the parties' contemplation. (vii) Because of the difficulties of testing in the case of each customer, past or current, whether such a customer is likely to do business with the employer in the future, a clause which is reasonable in terms of space or time will be likely to be enforced. Moreover, it has been said that it is the customer whose future custom is uncertain that is "the very class of case against which the covenant is designed to give protection…the plaintiff does not need protection against customers who are faithful to him" (John Michael Design Plc v. Cooke[1987] 2 All ER 332 , 334). (viii) On the whole, cases in this area turn so much on their own facts that the citation of precedent is not of assistance.”
"a matter of construction, including the question whether one obligation can be removed or severed without altering the nature of the contract and without having to add or modify the wording otherwise than by excision."
“Severance 26. Mr Laddie [Counsel for the ex-employer] submitted that the words "or interested" could be deleted or severed from clause 13.2.3. The judge dealt with this point shortly by saying that he did not find it appealing. Since he held that on its true construction the clause was not impermissibly wide, he did not need to say anything more. … 29. The second reason for not allowing severance is that it is well settled that parts of a single covenant cannot be severed; it is a requirement of severance that it can only take place where there are distinct covenants (as, for example, in 13.2 which enumerates separate covenants) and, perhaps, not even then. Clause 13.2.3 is, however, a single covenant preventing Ms Tillman from engaging or being concerned in a competing business in any one of several capacities, has to be read as a whole and cannot be severed, see Chitty para 16-215. 30. That is the effect of Attwood v Lamont[1920] 3 KB 571 where severance was refused in relation to specified trades, with respect to which the employer had no legitimate reason for preventing his ex-employee from carrying on or being concerned in. Younger LJ said at page 593:- "The learned judges of the Divisional Court, I think, took the view that such 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." This court also relied on Lord Moulton's speech in Mason v Provident[1913] AC 724 , 745 in which he said that it was no business of the courts to come to the assistance of an employer who had exacted an unreasonably wide covenant and, by applying their ingenuity and knowledge of the law, to carve out of the void covenant the maximum of what the employer might validly have required. Severance was also refused in the British Reinforced Concrete case for the reasons given in Attwood v Lamont. 31. This requirement that severance can only be applied to separate covenants and not to parts of a single covenant remains the law, since Attwood v Lamont was expressly stated in Beckett Investment Management Group Ltd v Hall[2007] ICR 1539 at paras 38-39 to have been adopted in later decisions. 32. Beckett also approved a threefold test propounded by Mr Peter Crawford QC sitting as a Deputy Judge of the High Court in Sadler v Imperial Life Assurance Company ofCanada[1988] IRLR 388 at paras 391-2:- "a contract which contains an unenforceable provision nevertheless remains effective after the removal or severance of that provision if the following conditions are satisfied: 1. The unenforceable provision is capable of being removed without the necessity of adding to or modifying the wording of what remains. 2. The remaining terms continued to be supported by adequate consideration. 3. The removal of the unenforceable provision does not so change the character of the contract that it becomes "not the sort of contract that the parties entered into at all"." 33. Mr Laddie submitted that this test had replaced the requirement that severance only applied to separate and not single covenants. But Beckett shows that that is not correct. The requirement is reflected in the third of the three tests adopted by Mr Crawford because it must always be doubtful whether parts of a single covenant can be deleted without the contract becoming "not the sort of contract that the parties entered into at all". It is, as Lord Moulton said, no business of the courts to create a valid covenant in order to replace an impermissibly wide covenant which an employer has sought to impose on the employee. 34. For those reasons, I do not think the words "or interested" can be deleted in order to save the covenant.”
“…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.”
