The Transparency of Lobbying, Non-party Campaigning and Trade Union Administration Act 2014 established it is the role of the Registrar to keep and publish the Registrar of consultant lobbyists, in which third party lobbyists declare the names of their clients, and whether or not they subscribe to a relevant code of conduct.
The Registrar has a duty to monitor compliance, and the power to undertake enforcement action against non-compliance. Therefore, it is for the Registrar to determine whether to launch any consultation into codes of conduct and the scope of such a consultation. I understand the Registrar is currently finalising the exact scope of the proposed consultation and will publish further details on the ORCL website when the consultation is launched.
It is also for the independent Registrar of Consultant Lobbyists to determine whether a code of conduct a registrant wishes to declare on the Register is 'relevant'. It is for the Registrar to determine whether to make known information about where a code of conduct has failed to meet the test of relevance, and such queries should be directed towards the Office of the Registrar of Consultant Lobbyists.
