The Guernica Group is an international initiative that brings together experienced litigators, investigators and other professionals who work to bring perpetrators of international crimes and grave human rights violations to justice; seize their ill-gotten assets for the benefit of their victims; and strengthen systems of accountability, truth-telling, reparation, and non-recurrence. Working in country and in partnership with affected communities, we offer a range of highly specialized skills to achieve accountability.

The Guernica Group provides highly technical advice and representation to assist individuals, civil society groups and governmental institutions in designing and implementing strategies to ensure accountability and redress for international crimes and human rights violations. We support transitional justice processes partnering with national actors in identifying alternative jurisdictions to initiate legal actions that seek to impact the relevant country encouraging domestic accountability with transformative effects.

In an effort to create a truly international and sustainable platform, The Guernica Group comprises three independent entities that share mission and values: Guernica 37 International Justice Chambers in London, an innovative, mission-driven, Barrister Chambers dedicated exclusively to international legal work; G37 Despacho Internacional in Madrid, the first legal office in Madrid specialized in international criminal law, universal and extraterritorial jurisdiction; and The Guernica Centre for International Justice in San Francisco, the first non-profit law firm in the State of California that seeks to represent all victims in their pursue for justice and accountability. 


The Guernica Group takes its name from one of the most heinous war crimes committed in modern history and immortalized by Pablo Picasso’s famous painting. The bombing of the town of Guernica in the Spanish Basque Country on 26 April 1937 by German and Italian warplanes at the request of the Spanish Nationalists, killed more than 1,600 civilians, the majority women, and children.
