Subsection (4) is also modelled on the deportation provision and concerns the question of detention where court proceedings are taken challenging the removal. Subsection (5) sets out the choice of places, based on the Schengen instruments, to which a refused person may be sent back. The most usual situation, at paragraph (a), is where the person is returned to the place from where he or she last embarked for the State. The remaining paragraphs set out the other possibilities, in line with the international norms.
