The request for a preliminary ruling concerned the interpretation of Article 2(1) of the Return Directive read in conjunction with recital 9 in the preamble to that directive and was made in proceedings between Mr Arslan, a Turkish national arrested and detained in the Czech Republic pending removal, who, during that detention, made an application for international protection.

The CJEU ruled that:

"1. Article 2(1) of Directive 2008/115/EC of the European Parliament and of the Council of 16 December 2008 on common standards and procedures in Member States for returning illegally staying third-country nationals, read in conjunction with recital 9 in the preamble, must be interpreted as meaning that that directive does not apply to a third-country national who has applied for international protection within the meaning of Council Directive 2005/85/EC of 1 December 2005 on minimum standards on procedures in Member States for granting and withdrawing refugee status during the period from the making of the application to the adoption of the decision at first instance on that application or, as the case may be, until the outcome of any action brought against that decision is known."

"2. Council Directive 2003/9/EC of 27 January 2003 laying down minimum standards for the reception of asylum seekers and Directive 2005/85 do not preclude a third-country national who has applied for international protection within the meaning of Directive 2005/85 after having been detained under Article 15 of Directive 2008/115 from being kept in detention on the basis of a provision of national law, where it appears, after an assessment on a case-by-case basis of all the relevant circumstances, that the application was made solely to delay or jeopardize the enforcement of the return decision and that it is objectively necessary to maintain detention to prevent the person concerned from permanently evading his return."
