The Spanish and international arbitration communities are mourning the passing of Carlos de los Santos, longtime head of arbitration and litigation at Garrigues and alternate member of the ICC International Court of Arbitration, who died suddenly on Wednesday at the age of 55.

De los Santos spent his entire career at Garrigues, was promoted to partner in 2003 and headed the litigation and arbitration department at the firm since 2009. The department counts some 210 lawyers throughout the firm's offices in Europe, Asia and the Americas.
