In order to ensure a fair sharing of responsibility, solidarity as enshrined in Article 80 and a balance of effort between Member States, a mandatory solidarity mechanism should be established which provides effective support to Member States under migratory pressure and ensures swift access to fair and efficient procedures for granting international protection. Such a mechanism should provide for different types of solidarity measures of equal value and should be flexible and able to swiftly adapt to the evolving nature of the migratory challenges. The solidarity response should be designed on a case-by-case basis in order to be tailor-made to the needs of the Member State in question.
