Fermandois & Cía

Chile > Public law Tier 1

'The most important in the country for public law matters', Fermandois & Cía  houses a ten-strong practice that has an enviable name in the market for prominent public law litigation, including recent high-profile disputes before the Supreme Court and the Constitutional Court; the group is also well known for its specialised legal opinions on complex private-public conflicts. Fielding several constitutional and administrative law professors from the Catholic University of Chile, the firm's principal figure is founding partner and former Chilean Ambassador to the US Arturo Fermandois ('the most prominent public law lawyer in Chile'), who, in relation to Chile's proposed new constitution, was recently appointed to the expert commission that drafted the constitutional amendment. Other key advisers are constitutional expert José Manuel Díaz de Valdés (an independent adviser and consultant in public law matters until 2018) and Domingo Poblete ('solid international background'), who consistently plays key roles in high-level cases. At associate level, litigator Cristóbal Zepeda and Andrés Vodanovic focus on constitutional and economic regulatory matters.


Great for the deep knowledge it has in all areas of Chilean public law, the professionalism of its lawyers, and the ease with which it adapts to the needs of clients.

The Fermandois law firm is the most important in the country for public law matters.

The team is made up of outstanding professionals, with great experience and skills, which, in my opinion, makes them the best when compared with other law firms.

The team led by Arturo Fermandois is extraordinary and the lawyers complement each other very well. They have deep legal knowledge because they are professors and also demonstrate practical knowledge that comes from years of experience in highly complex cases.

Arturo Fermandois is the most prominent public law lawyer in Chile – a university professor and longstanding lawyer with solid knowledge and ability that produce optimal results.

Arturo Fermandois is an expert in public law, but he also has great knowledge of the political, academic and international world. All these qualities enable him to be one day litigating in front of the Constitutional Court of Chile, and the next day acting for a CEO of a transnational corporation – few lawyers in Chile have this level of versatility coupled with world-class expertise.

Arturo Fermandois is characterised by his deep knowledge and judicial skills – having his support and that of his team are of vital importance for the development of our activities.

Domingo Poblete belongs to a new generation of constitutionalists; he has a solid international background that allows him to interact naturally with the figures defining the country from political and business points of view. He also understands the client’s business and anticipates the problems that a changing scenario, such as the Chilean one, generates for businesses.
