Following nominations from interested Member States, a group of representatives from the Member States was set up in April 2015 which discussed the draft Terms of Reference for each working group during dedicated audio-conferences in May 2015.
Nakon što su zainteresirane države članice provele imenovanja, u travnju 2015. osnovana je skupina predstavnika država članica koja je u svibnju 2015. na posebnim audiokonferencijama raspravljala o nacrtu opisa poslova svake radne skupine.
