Mínimum criteria in deprivation of liberty cancelled “when they cease to be necessary for the investigations for which they were stored”». 78. The CPT grants particular relevance, as it stated in its 2nd General Report, to three rights granted to detainees: the right to notify the facts of their detention to a third party of their choice; the right to a lawyer; and the right to request a medical examination. It is found that these rights, established in article 520.2 of the Criminal Procedure Act, are observed at all the facilities visited. Nevertheless, it should be ensured that the written information provided to persons deprived of liberty, on the grounds for their detention and their rights, is worded comprehensibly in a language that they understand, and that such information includes the possibility of instituting an habeas corpus proceeding. It should likewise be ensured that any person deprived of liberty be afforded access, in the shortest time possible, to a lawyer ensuring also due confidentiality in the interviews that they hold. In the same context, concern exists as to the facts observed in certain visits which, although not many, are sufficiently serious for the responsible authorities to correct them as soon as possible. At certain visits it has been observed, in the custody forms for some of the detainees, that they had held two “interviews” or “processes” with police officers before declaring and being assisted by a lawyer. Accordingly, it is deemed necessary that, when an interview is held without assistance of a lawyer, the purpose of such interview, in addition to its duration, should be recorded in the relevant custody form and also in the records of investigation sent to the court authority.
