Without the flexibility to make suitable provisions by secondary legislation, which is always subject to review afterwards by the Oireachtas anyway, the potential delays in securing the passage of a Bill could create difficulties for port or airport authorities which would have to await the passage of such legislation before they could act legally to allow non-nationals to land in their ports. It is not a power that is used frequently but it is a power that is best dealt with by order rather than primary legislation. Therefore I urge Senators to accept this amendment.
