Public servants should be proactive in advising possible lobbyists when attending a meeting, participating in a conference call, etc., that you are a Designated Public Official. This may be particularly useful in meetings where there are large numbers of officials present and the identity and grade of each official may not be known to those outside of the public service.
Another such means of being proactive for a DPO would be to include a line in his or her email signature stating:
*Designated Public Official under Regulation of Lobbying Act, 2015. See www.lobbying.ie.
