Peru was the first country in Latin America to pass a law to regulate lobbying.  

Ley de gestion de intereses en la administracion publica, No. 28024/2003 aims to ensure transparency in relations between lobbyists and 

public decision makers.

Anyone wishing to carry out this activity is obliged to enroll in a public register, indicating the interest they represent and the client, if any, and reporting every six months on the activity carried out.

The law identifies two different categories of lobbyists: the gestor de intereses propios and the gestor profesional.

Following the law, the government approved a regulation which, in Article 37, establishes a series of principles of professional ethics for lobbyists such as the obligation to always transmit truthful information, the prohibition to offer gifts and the duty to report on the lobbying activity carried out.
