On the role of national parliaments in monitoring subsidiarity, one of the issues that arose early in the course of the debate on the Convention was the question of a European congress or Senate. However, it has been generally accepted that adding another tier of scrutiny would make Europe more opaque and less understandable than at present and that ways must be found to provide for national parliamentary scrutiny which does not obscure what is happening but rather clarifies it. We have already begun to take steps like that in the Oireachtas in relation to decision-making.
