44According to settled case-law, the choice of the legal basis for a European Union measure must be based on objective factors amenable to judicial review, which include the aim and content of that measure and not on the legal basis used for the adoption of other European Union measures which might, in certain cases, display similar characteristics. In addition, where the Treaty contains a more specific provision that is capable of constituting the legal basis for the measure in question, the measure must be founded on that provision (Parliament v Council, paragraph 34 and the case-law cited).
