This chapter identifies the strengths and weaknesses of Nuevo León’s current integrity framework, focusing on public ethics and management of conflicts of interest within its public administration and providing guidelines for strengthening its institutional and normative framework. The chapter finds that the current Ethics Code and integrity rules could be revisited, moving to a more balanced approach based on evidence. Additional guidelines could be adopted to assist public officials in dealing with ethical dilemmas and conflicts of interest and to identify areas of risk in public sector activities. It is also recommended that Nuevo León consider adopting a more strategic approach toward using the declarations requirement as a way of implementing integrity policies and practices. Finally, this Chapter underlines how strengthening the recruitment process and human resources management practices can help promote integrity throughout the public administration.
