Estudio Gabriel Macchiavello

Work Department



Partner. Specializes in environmental conflicts and conflicts with government agencies, as well as corporate advice in environmental regulation and its adequate analysis to avoid or mitigate those conflicts.


His solid academic background, and his 30-year old expertise in litigation in different fields, have made him an expert in highly complex administrative procedures and legal processes on toxic tort cessation and redress.

He was a founding partner of Rattagan Macchiavello Arocena & Peña Robirosa at the time of its creation, in 2005.

His professional experience in litigation, his solid academic training and his eighteen years collaborating with Mr. Gabriel Macchiavello make him one of the most experienced specialists in administrative procedures and judicial cases related to environmental conflicts in different scenarios (civil, criminal, administrative, etc.). He has a deep understanding of the special nature and particularities of these type of procedures, since environmental conflicts are class actions promoted by individuals, NGOs or government agencies, very different from regular civil or administrative cases.

In this field, he intervened in high-profile environmental cases representing interests of top domestic, international and foreign companies with activity in our country and in Latin America. He has participated in several toxic torts in the upstream, midstream and downstream oil, mining and chemical industries, as well as other industries,  leather, meat processing, food, paint, water extraction and bottling, petcoke calcination and storage, transgenic seeds and agrochemicals’ production, herbicides and diesel engines emissions.


Spanish, English.


He earned his Law degree from the University of Buenos Aires in 1995. From 1997 through 1998, he completed a Postgraduate course in Economic Administrative Law at the Argentine Catholic University, with the highest GPA of his class, and the maximum grade for his thesis.
