Guarantee-based defence before the Audiencia Nacional · Author: Francisco Javier Martín Porras, criminal lawyer and court expert · SCJE team
Few accusations weigh as much as terrorism, and few demand such a technical defence: broad offences (glorification, collaboration, self-indoctrination), investigation before the Audiencia Nacional, secrecy of proceedings and mostly technological evidence. Our digital forensic profile is decisive where the case is, almost always, a telephone and a set of interpreted social networks. Everyone has the right to the best defence; on this ground, moreover, they need it.
In brief. In brief. Membership of a terrorist organisation: prison of 6 to 12 years (leaders up to 15). Collaboration: prison of 5 to 10 years (art. 577). Glorification or humiliation of victims: 1 to 3 years (art. 578). Centralised investigation, frequent pre-trial detention and an aggravated prison regime.
The terrorism offences of articles 571 to 580 of the Criminal Code combine severe penalties with deliberately broad definitions: membership of an organisation, any act of collaboration, self-indoctrination and public glorification. The investigation is centralised before the Audiencia Nacional, with central investigating courts, frequent secrecy of proceedings and pre-trial detention. The evidence is mostly technological: a telephone, browsing histories and social networks interpreted by police reports.
Our defence: our own forensic examination of devices, establishing the real context of messages, irony and shared authorship; the constitutional border of glorification with freedom of expression (STC 112/2016 and later case law); in self-indoctrination, the requirement of a real terrorist purpose, not mere curiosity; and strict control of the technological investigation measures and of the secrecy of proceedings.

Summary drawn from the Spanish source page for orientation purposes. The applicable provisions are those of the Criminal Code in force at the relevant time; each case requires individual analysis by a criminal lawyer.
Original commentary by the firm on articles 571 to 580 CP, updated to the case law of the Constitutional Court and the Supreme Court. The case is almost always a telephone and interpreted social networks: our own digital forensic laboratory turns police impressions into verifiable numbers, contexts and dates.
Glorification requires a real risk of incitement: age of the messages, satirical tone, real reach of the account and absence of a call to action are the defensive lines that have sustained Supreme Court acquittals.
Only habitual access with the purpose of preparing oneself integrates the offence: journalistic research, academic interest or morbid curiosity do not. The forensic analysis of the device decides these cases.
The wildcard offence of prosecutions requires intent to further the specific terrorist activity: the defence concentrates on what was actually known and when.
Confiscation reaches family assets: the patrimonial defence, with documented lawful origin, runs in parallel to the criminal defence from the first search.
