109The principle of the protection of legitimate expectations is one of the fundamental principles of the European Union. The right to rely on that principle assumes that three conditions are satisfied. First, precise, unconditional and consistent assurances originating from authorised and reliable sources must have been given to the person concerned by the administration. Second, those assurances must be such as to give rise to a legitimate expectation on the part of the person to whom they are addressed. Third, the assurances given must comply with the applicable rules (see judgment of 15 July 2015, Socitrel and Companhia Previdente v Commission, T‑413/10 and T‑414/10, EU:T:2015:500, paragraph 174 and the case-law cited).
