The UK detention of former Chilean dictator Augusto Pinochet in 1998 was hailed at the time as an unprecedented demonstration of the possible efficacy of ‘global civil society’ networks in holding former heads of state to account for crimes against humanity. This article nonetheless questions the concept, as well as the practical efficacy, of globalised civil society action or ‘human rights lawyering’ as a trigger for the prosecution of past human rights violations. Based on extensive field research, the article argues that domestic factors, including domestic actor pressure and national judicial change, have proved more significant than international law or international activism in recent re-irruptions of the human rights accountability issue in Latin America's Southern Cone. The case of El Salvador, meanwhile, shows that transnational initiatives, while occasionally successful in their own right, have not been able to interrupt or foreshorten domestic post-transitional trajectories to the extent of independently creating favourable accountability conditions.
