"Pausing there, I consider it fair to say that the Paris office has all the trappings that, to clients and other third parties, would make it practically indistinguishable from an independent French law firm of similar size providing similar services, but with the added benefits of being part of an international firm."
"The overall picture that the evidence presented to me was not at either end of the scale. The Paris office was not a wholly independent business that was merely affiliated to a separate international organisation. Nor was it merely an outpost or satellite presence of the firm, controlled and managed from London. It was an office that enjoyed the mixture of delegated autonomy and integrated control that I would perceive to be within the normal range for a substantial national office that is part of an international global law business of this size and complexity."
"79. Pausing there, I conclude that, in principle (though, of course, application of this typology to the given facts may be tricky) cases can potentially, and to start with, be divided into three types: (a) those in which (at the relevant time or during the relevant period), the claimant worked in Great Britain; (b) those in which the claimant worked outside Great Britain; and (c) those in which the claimant lived and worked for at least part of the time in Great Britain. 80. In cases of type (a) there will be territorial jurisdiction. In cases of type (b) the presumption is against jurisdiction unless there is something which puts the case in an exceptional category, such that the employment has much stronger connections both with Great Britain and British employment law than with any other system of law. That is a question of fact and degree. A non-exhaustive range of factors could be relevant. In cases of type (c) the case does not have to be "truly exceptional" for territorial jurisdiction to be established; and the comparative exercise called for in a type (b) case is not required. There merely needs to be a sufficiently strong connection with Great Britain and British law."
"In matters relating to individual contracts of employment, jurisdiction shall be determined by this Section, without prejudice to … in the case of proceedings brought against an employer, point 1 of Article 8."
"1. Subject to this Regulation, persons domiciled in a Member State shall, whatever their nationality, be sued in the courts of that Member State."
"A person domiciled in a Member State may also be sued: (1) where he is one of a number of defendants, in the courts for the place where any one of them is domiciled, provided the claims are so closely connected that is expedient to hear and determine them together to avoid the risk of irreconcilable judgments resulting from separate proceedings;"
"(1) As originally enacted,section 196 of the Employment Rights Act 1996 contained provisions governing the application of the Act to employment outside Great Britain. That section was repealed by theEmployment Relations Act 1999 . Since then the Act has contained no express provision about the territorial reach of the rights and obligations which it enacts (in the case of unfair dismissal, bysection 94(1) of the Act ); nor is there any such provision in theEquality Act 2010 . (2) The House of Lords held in Lawson that it was in those circumstances necessary to infer what principles Parliament must have intended should be applied to ascertain the applicability of the Act in the cases where an employee works overseas. (3) In the generality of cases Parliament can be taken to have intended that an expatriate worker – that is, someone who lives and works in a particular foreign country, even if they are British and working for a British employer – will be subject to the employment law of the country where he or she works rather than the law of Great Britain, so that they will not enjoy the protection of the 1996 or 2010 Acts. This is referred to in the subsequent case-law as "the territorial pull of the place of work". (This does not apply to peripatetic workers, to whom it can be inferred that Parliament intended the Act to apply if they are based in Great Britain.) (4) However, there will be exceptional cases where there are factors connecting the employment to Great Britain, and British employment law, which pull sufficiently strongly in the opposite direction to overcome the territorial pull of the place of work and justify the conclusion that Parliament must have intended the employment to be governed by British employment legislation. I will refer to the question whether that is so in any given case as "the sufficient connection question".
"… The question whether, on given facts, a case falls within the scope of section 94(1) is a question of law, but it is also a question of degree. … The question of law is whether section 94(1) applies to this particular employment. The question of fact is whether the connection between the circumstances of the employment and Great Britain and with British employment law was sufficiently strong to enable it to be said that it would be appropriate for the employee to have a claim for unfair dismissal in Great Britain."
"It will always be a question of fact and degree as to whether the connection is sufficiently strong to overcome the general rule that the place of employment is decisive"
"… the appeal court conducting a review of the trial judge's decision will not conclude that the decision was wrong simply because it is not the decision the appeal judge would have made had he or she had been called upon to make it in the court below. Something more is required than personal unease and something less than perversity has to be established. …"
