77Second, as regards the situation in which the transfer of responsibility for examining the application for international protection to a Member State other than the requested Member State took place after a take back request made by a third Member State has been accepted, it should be borne in mind, first, that the Dublin III Regulation is based on the essential principle, set out in Article 3(1), that an application for international protection must be examined by a single Member State only, which means that a single Member State may be considered to be, at a given moment, the Member State responsible for examining an application for international protection (see, to that effect, judgment of 2 April 2019, H. and R., C‑582/17 and C‑583/17, EU:C:2019:280, paragraph 78).
