"10 The United Kingdom Government and the Commission suggest that the essential criterion is whether the transferee is put in possession of a going concern and is able to continue its activities or at least activities of the same kind. The Netherlands Government emphasizes that, having regard to the social objective of the directive, it is clear that the term 'transfer' implies that the transferee actually carries on the activities of the transferor as part of the same business.
"12 According to the case-law of the Court (judgment inCase C-209/91 Watson Rask and Christensen v ISS Kantineservice[1992] ECR I-5755 , at paragraph 15), the directive is applicable where, following a legal transfer or merger, there is a change in the legal or natural person who is responsible for carrying on the business and who by virtue of that fact incurs the obligations of an employer vis-à-vis the employees of the undertaking, regardless of whether or not ownership of the undertaking is transferred.
"10 The aim of the directive is to ensure continuity of employment relationships within an economic entity, irrespective of any change of ownership. The decisive criterion for establishing the existence of a transfer within the meaning of the directive is whether the entity in question retains its identity, as indicated inter alia by the fact that its operation is actually continued or resumed (Case 24/85 Spijkers [1986] ECR 1119 , paragraphs 11 and 12, and, most recently, Joined Cases C-171/94 and C-172/94 Merckx and Neubuys[1996] ECR I-1253 , paragraph 16; see also the advisory opinion of the Court of the European Free Trade Association of19 December 1996 in Case E-2/96 Ulstein and Røiseng , not yet reported, paragraph 27).
"26 Whilst such an entity must be sufficiently structured and autonomous, it will not necessarily have significant assets, material or immaterial. Indeed, in certain sectors, such as cleaning and surveillance, these assets are often reduced to their most basic and the activity is essentially based on manpower. Thus, an organised grouping of wage earners who are specifically and permanently assigned to a common task may, in the absence of other factors of production, amount to an economic entity.
"25 Similarly, Directive 77/187 must be capable of applying where, as in those cases before the national courts, a undertaking which used to have recourse to another undertaking for cleaning of its premises or part of them decides to terminate its contract with the other undertaking and in the future to carry out the work itself.
"19 It must be recalled that the aim of Directive 77/187 is to ensure continuity of employment relationships within an economic entity, irrespective of any change of ownership. The fact that the activity carried on by such an entity is awarded successively to different operators by a public body cannot exclude the application of Directive 77/187, if passenger transport by bus does not involve the exercise of public authority (see, to that effect, joined cases C-173/96 and C-247/96 Sánchez Hidalgo and others[1999] IRLR 136 , paragraphs 21 and 24).
"The next question to be decided would be whether the economic entity had retained its identity following the transfer. The tribunal decided that it was clear that there were differences in the way that ECM carried out the VAG contract. For example, it was a totally networked system. The administration was done centrally in Carlisle. There were no local delivery centres, drivers were expected to be out five nights a week and the Pyewipe area at Grimsby was not used. It could be argued that the yardmen's inspection duties were partly to protect their own employers (Axial Ltd) at the time. The tribunal nevertheless concluded that the customers essentially were the same, and that the work that was going on was essentially the same. Cars were unloaded at Grimsby, were put onto transporters, and were driven to VAG dealers. The end result was the same. It was true to say that ECM did not take on any of [Axial's] staff but if this in itself was taken to be a good reason for saying that the Regulations of 1981 do not apply, this would give an opportunity for any employer to avoid the Regulations, simply by not giving an employee a contract. The tribunal decided that this was not an appropriate way of interpreting the Regulations. …
"It seems to us that Süzen's case[1997] ICR 662 reaffirms earlier decisions of the European Court of Justice. It re-emphasises the importance of the court's judgment in the Spijkers case [1986] ECR 1119 . But the court does not expressly deal with the situation in which an employer decides not to take on employees in an attempt to avoid the operation of the Regulations of 1981 and where if he had taken them on there would be a transfer within the meaning of the Regulations. It seems to us that, when properly understood, there is no conflict between the decision in Schmidt's case[1995] ICR 237 and the decision in Süzen's case: as Kennedy LJ said in Betts[1997] ICR 792 , 807, there may have been a change in emphasis.
"In this case, on the tribunal's findings, the transferee did not take on the men precisely because they were asserting that the Regulations of 1981 applied and were threatening proceedings on that basis. An obvious inference from the facts is that thereby the transferee hoped to defeat their claims. The question arises, therefore, where it is possible for a transferee to cause the Regulations to be disapplied by refusing to take on the workforce. Another way of putting the point is that if the taking on or not of the workforce controls the application or otherwise of the Regulations, then the question at issue is circular. The issue as to whether employees should have been taken on cannot be determined by asking whether they were taken on.
"The appeal tribunal[1998] ICR 631 , 639 E went further and said that it was a legitimate inference that ECM had refused to take on the staff precisely in order to prevent the Regulations of 1981 from applying and that if they had been taken on then the Regulations would clearly have applied. This was criticised as an erroneous approach in law, first, because it was not a legitimate inference from the decision of the employment tribunal that ECM had refused to take on the staff in order to avoid the transfer; rather it was because of the threat of litigation. Secondly, and in any event, there was no evidence of how many of the staff might have been taken on if there had been no threat of litigation.
"It seems to us, particularly as these are only guidelines, but always within the parameters set by Kennedy LJ, that one is looking to see whether the staff is "substantially the same", that the apparent contradictions, or at any rate uncertainties, in the formulation of these questions, when looking at an alleged transfer of a labour-intensive undertaking, can be reconciled. It may be that in a given case the question will be answered by totting up to see whether a majority of staff is taken on. In another case there may be a minority in number, but on examination of the skills of the employees, be they managerial, administrative or technical, the skills of those who have been taken on outweighs the mere numerical factor, such that, albeit not a majority, nevertheless those taken on constitute a major part. There may perhaps even be a reverse case where the taking on of a numerical majority would be outweighed if the significant employees, in terms of skills, who in fact constituted the important part of the undertaking, were not taken on. Again these precise questions about numbers of staff become less significant if there is a transfer of something else other than staff, so that the picture can be looked at in the round."
'In this case, on the tribunal's findings, the transferee did not take on the men precisely because they were asserting that the Regulations of 1981 applied and were threatening proceedings on that basis. An obvious inference from these facts is that thereby the transferee hoped to defeat their claims. The question arises, therefore, [whether] it is possible for a transferee to cause the Regulations to be disapplied by refusing to take on the workforce.'
"15 Against this background Kennedy LJ then turned to Süzen v Zehnacker Gebäudereinigung G.m.b.H. Krankehausservice (Case C-13/95 )[1997] ICR 662 . Kennedy LJ accepted[1997] ICR 792 , 807F-G:
'That the decision in Süzen does represent a shift of emphasis, or at least a clarification of the law, and that some of the reasoning of the earlier decisions, if not the decisions themselves, may have to be reconsidered.'
