Article 520 bis Spanish Criminal Procedure Act: Detention and incommunicado detention in terrorism cases

Article 520 bis permits the detention of a person suspected of the offences referred to in Article 384 bis to be prolonged for up to a further forty eight hours beyond the ordinary seventy two, subject to a reasoned judicial authorisation, and it governs the request for incommunicado detention.

Wording of Article 520 bis of the Spanish Criminal Procedure Act

1. Every person detained as an alleged participant in any of the offences referred to in Article 384 bis shall be brought before the competent judge within the seventy two hours following the detention. Nevertheless, the detention may be prolonged for the time necessary for the purposes of the investigation, up to a maximum limit of a further forty eight hours, provided that such extension, requested by a reasoned communication within the first forty eight hours from the detention, is authorised by the judge within the following twenty four hours. Both the authorisation and the refusal of the extension shall be adopted by a reasoned decision.

2. Where a person has been detained on the grounds set out in the preceding number, the judge may be asked to order the incommunicado detention of that person, and the judge shall rule upon it, by a reasoned decision, within twenty four hours. Where incommunicado detention has been requested, the detainee shall in all cases be held incommunicado, without prejudice to the right of defence which that person enjoys and to the provisions of Articles 520 and 527, until the judge has handed down the relevant decision.

3. During the detention, the judge may at any time require information and ascertain, personally or by delegation to the investigating judge of the district or area in which the detainee is held, the situation of the detainee.

Effect. The provision imposes no penalty. Its breach renders the deprivation of liberty unlawful, founds an application for habeas corpus under Article 17.4 of the Constitution and may entail the nullity of the statements taken and the exclusion of the evidence derived from them.

Requirements and procedure

  1. That the detention relate to a person alleged to have participated in one of the offences referred to in Article 384 bis, namely offences committed by armed bands or by terrorist or rebel elements.
  2. A reasoned request for the extension lodged within the first forty eight hours from the detention.
  3. A judicial authorisation, granted within the following twenty four hours, by a reasoned decision, with an absolute limit of a further forty eight hours.
  4. In the case of incommunicado detention, a request to that effect and a reasoned judicial decision within twenty four hours, without prejudice to Articles 520 and 527.

Defence strategy

Correct classification of the offence. The special regime applies only to the offences referred to in Article 384 bis. Where the classification does not stand up upon examination of the file, the extension of the detention loses its legal basis and the deprivation of liberty becomes unlawful from the seventy second hour.

Timeliness and reasoning of the extension. The request must be made within the first forty eight hours and the authorisation within the following twenty four. A request or an authorisation which is out of time, or one which merely reproduces a form of words, is a defect which is not remedied by the subsequent decision.

Scope of the incommunicado detention. Incommunicado detention does not suppress the right of defence, and Articles 520 and 527 delimit which rights may be restricted and which may not. Any restriction beyond that catalogue is a ground for the nullity of the steps taken during that period.

Judicial control during the detention. Paragraph 3 confers upon the judge a duty of continuous supervision. The absence of any record of that supervision in the file is a relevant element in the challenge to the conditions of the detention and to any statement taken during it.
