A Unique Approach To International Criminal Law

Cored in the notion of accountability as a key mechanism, we use the Law to transform societies emerging from conflict to achieve peace, justice and security. We provide legal representation and advisory services to victims, civil society groups, businesses, and governments to further transitional justice, defend human rights, enforce international norms and international criminal law.

Guernica 37 takes its name from the first crime against humanity committed in modern history and immortalised by the famous painting by Pablo Picasso. The bombing of Guernica in the Basque Country on 26 April 1937 was carried out during the Spanish Civil War by the Spanish Nationalist forces' allies, the Nazi German Luftwaffe Condor Legion and the Fascist Italian Aviation Legionaria. The Guernica bombing is considered one of the first widespread or systematic attack on a civilian population in which 1,654 people were killed.

According to Basque Country president at the time, Jose Antonio de Aguirre, "the Germans scorched the city later firing machine guns at the women and children who were fleeing in panic". The Guernica attack has become known as one of the first recorded attacks on a civilian population thereby constituting a crime against humanity."
