Our Staff

Managing Partner

Hugo Bunge Guerrico

Mr. Hugo Bunge Guerrico earned his Law degree from the University of Buenos Aires in 1972, and has more than forty years of professional experience.

He was founding partner at Nicholson & Cano Abogados in 1976 and, was the managing partner of the firm from 1983 through 1991. In that role, he was in charge of the legal orientation, the scientific quality and the practicality of the advice offered to all the firm’s clients. This role turned him into a general practitioner with knowledge in Constitutional Law, Administrative Law, Procedure Law, expert in regulations applied to specific corporate activities, as the sugar industry and the reinsurance regulatory framework.

As leading attorney of the Ledesma group, between 1976 and 1995, and several other sugar companies and leading insurance companies, he participated in complex conflicts among private companies and the Federal Administration, and inter-company conflicts, which allowed him to specialize in the strategic direction of these types of litigations.

Since 2002, he was of counsel to Gabriel Macchiavello then partner with Allende & Brea collaborating with him in his clients’ judicial and administrative procedures in connection with Environmental Law.

In 2005, he was one of the seven partners that constituted the firm “Rattagan, Macchiavello, Arocena.” Since then, he has participated with Mr. Gabriel Macchiavello and Mr. Pedro Zambrano in the strategic direction of environmental conflicts of the firm’s clients.

Partner

Pedro L. Zambrano

Mr. Pedro L. Zambrano 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 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.

From 1990 through 1999, he worked at the Federal Administrative Courts, where he was promoted to Court Clerk. In 2000, he was recruited as senior associate at Allende & Brea, where he first collaborated in the creation of the Administrative Law Area and then he   consolidated the Environmental Law Area in that law firm.

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.

His daily connection with the environmental conflict, and his academic profile have allowed him to provide reliable legal advice services related to the analysis of environmental laws, regulations and standards  to avoid –or mitigate- environmental conflicts with regulatory authorities or industrial facilities’ neighbors. On the other hand, he regularly provides advice in several processes of public work’, environmental impact assessment, generation of renewable energies, corporate acquisitions and identification of legal and environmental contingencies.

He taught specialization programs at Argentine Catholic University’s Law School, and the subject Administrative Law at the University of Buenos Aires and Universidad Austral, where he also lectured at many conferences in the field.

Among his multiple academic Works, we can highlight his publications on Environmental Constitutional Law: “El daño ambiental y la obligación de remediar” [Environmental Damage and the Obligation to Remediate], written with Mr. Gabriel Macchiavello for the Energía & Negocios magazine, Year 10, No. 107, June 2005; or “El derecho de defensa en juicios ambientales” [The justify to a Defense in Toxic Torts], La Ley magazine, 11/29/06, page 5, written on occasion of the Supreme Court ruling in the case “ASSUPA” in August 2006, when an exception for insufficiency of a pleading was sustained, marking an inflection point in legal precedence, which allowed a defendant to prove his case in the face of generic environmental arguments.

His academic training in Administrative Law and legal processes has led him to publish works on precautionary measures, as “Medidas cautelares autónomas y el derecho de defensa en juicio: ¿Por el artículo 12 de la Ley 19.549 o por el artículo 230 del Código Procesal?” [Autonomous Precautionary Measures and the justify to a Defense in Trial: Through Section 12 of Law 19 549 or Section 230 of the Procedure Code?], La Ley magazine, 1998-C, pages 344 – 354;

Prescription and Limitation in View of the New Regulation on Pre-Litigation Procedures”, Lexis Nexis, Collection of Legal Monographies No. 155, Buenos Aires, 2006.
