51It should be recalled that an action for damages is an autonomous form of action, with a particular purpose to fulfil within the system of legal remedies and subject to conditions of use dictated by its specific purpose. Whereas actions for annulment and for failure to act seek a declaration that a legally binding measure is unlawful or that such a measure has not been taken, an action for damages seeks compensation for damage resulting from a measure or from unlawful conduct, attributable to an EU institution or body (judgment of 7 October 2015, Accorinti and Others v ECB, T‑79/13, EU:T:2015:756, paragraph 61).
