The fact that employing non-nationals without employment permits will now be a criminal offence – and potentially one of great seriousness – makes it necessary to ensure that sufficient powers exist to enable such offences to be identified and detected. Accordingly, subsections (5) to (9) of this new section provide powers for a garda to search premises, by warrant of the District Court if necessary, to prosecute for the obstruction of such searches and to arrest an obstructer without a warrant.
