results of questioning, the detainees might have been set free, transferred to another detention unit, e.g. from CPIP to DSG, left in custody, marked to stand before a tribunal or selected for execution. There is no reliable statistics available; according to members of CPIP filtering commission interrogated by their Nationalist captors after 1939, some 50% of captives were freed, some 25% were marked for further incarceration and some 25% were executed. Suspects supposed to stand trial might have faced different types of judicial or quasi-judicial bodies. Regular system of district courts continued to operate, but it could not cope with the scale of detentions. In August 1936, the government set up Tribunal Especial dedicated exclusively to dealing with crimes of "rebellion and sedition"; in September 1936 it was aided by a new type of judicial body, Tribunal Popular de Responsabilidades Civiles, and in October of the same year by Jurados de Urgencia and Jurados de Guardia, both abolished in March 1938; it was not the case of Tribunal Especial de Espionaje y Alta Traición, set up in June 1937. Most of these tribunals had a mixed composition of professional judges/lawyers and non-professional jury members recruited from the public; they admitted, at least in theory, various degree of defense or self-defense, but there was no appeal. The tribunals were created to dispense fast and smooth justice but failed to do so; e.g. there were only 389 defendants who appeared before the Madrid Tribunal Especial in 1936. There is only partial statistics of verdicts adopted; it seems that around 50% of defendants were absolved and that some 8% were sentenced to capital punishment. Perhaps the best known case of Madrid execution following trial and death sentence is this of Joaquín Fanjul. Executions might have taken place during or shortly after the apprehension, during incarceration in prison/detention centre or at one of execution sites, the latter following less or more formal administrative/juridical decision or resulting from action unsanctioned even by a dubious procedure. There is no systematic data allowing quantitative estimates, but it is believed that the number of on-the-spot executions was highest during initial months of the war and decreased rapidly afterwards. The best-known form of killings were so-called paseos and sacas. The former usually stands for small-scale unofficial executions, while the latter typically denotes larger extractions of inmates from detention sites, often substantiated by some form of formal decision.
