The public sector as well as public or private companies that focus on doing business with the public sector or wish to shape the social discourse are subject to numerous special regulatory provisions. Whether registrations and obligations arising from the Lobby Register Act, the applicability and implementation of the Public Corporate Governance Codex or procurement-related areas such as the Supply Chain Due Diligence Act, we advise the public sector and companies on the special challenges in business dealings between the state and companies.
