27The concept of ‘objective reasons’ for the purposes of clause 5(1)(a) of the FTW Framework Agreement must, as the Court has already held, be understood as referring to precise and concrete circumstances characterising a given activity, which are therefore capable, in that particular context, of justifying the use of successive fixed-term employment contracts. Those circumstances may result, in particular, from the specific nature of the tasks for the performance of which such contracts have been concluded and from the inherent characteristics of those tasks or, as the case may be, from pursuit of a legitimate social-policy objective of a Member State (Angelidaki and Others, paragraph 96 and case-law cited).
