Regulations 2016/1624 and 2019/1896 have gradually turned Frontex into the focal point and information and multipurpose hub in EU external border control. They introduce and enhance the legal provisions covering the inter-agency cooperation of Frontex with other EU agencies, with some implications for fundamental rights and accountability obligations. Against the relevant lifting of the new European Border and Coast Guard mandate and staff, the formal recognition of fundamental rights does not guarantee their practical respect.
