26Article 11 of the Directive, the purpose of which is to place a time-limit on the exercise of the rights conferred by the Directive on the victim, is, on the other hand, of a neutral character. As is clear from the 10th recital in the preamble to the Directive, the aim of that provision is to satisfy the requirements of legal certainty in the interests of the parties involved. The establishment of the time-limits within which the victim's action must be brought must therefore satisfy objective criteria.
