Mr. John Twomey:

Perhaps I could address the question. For background, every checkpoint is authorised in law. Following the introduction of revised legislation on mandatory alcohol tests, random breath-testing was enabled, prior to which it was on the basis of reasonable suspicion. There is authorisation for every mandatory alcohol checkpoint that has been conducted. An inspector or above must authorise it in law. That evidence is subsequently produced in court for any prosecution. That evidence was initially in a paper-based system and, at a later stage, it became part of our PULSE system.
