Segi is a Basque pro-independence and revolutionary left-wing organization. It forms part of the Basque National Liberation Movement and is aligned with Langile Abertzaleen Batzordeak and Batasuna.
Segi is proscribed as a terrorist organisation (as a member of ETA) by both the Spanish and French authorities as well as the European Union as a whole. In its decision, on 27 February 2007, the Grand Chamber of the European Court of Justice (ECJ) dismissed the appeal of the illegal Basque organisation "Gestoras Pro Amnistia" and Segi members against their dismissal by the European Council with claims for damages suffered as a result of inclusion in the "terrorist list". The UK intervened with Spain – it was the only other EU state to do so, as a symbol of the support of the rest of the European Council.
