51Where, as in the main proceedings, neither the conditions under which observance of the rights of defence of illegally staying third-country nationals is to be ensured, nor the consequences of the infringement of those rights, are laid down by EU law, those conditions and consequences fall within the scope of national law, provided that the rules adopted to that effect are the same as those to which individuals in comparable situations under national law are subject (the principle of equivalence) and that they do not make it impossible in practice or excessively difficult to exercise the rights conferred by the European Union legal order (the principle of effectiveness) (see, to that effect, inter alia, judgments in Sopropé, EU:C:2008:746, paragraph 38; Iaia and Others, C‑452/09, EU:C:2011:323, paragraph 16; and G. and R., EU:C:2013:533, paragraph 35).
