Rule 35 of the Standard Minimum Rules provides: (1) Every prisoner on admission shall be provided with written information about the regulations governing the treatment of prisoners of his category, the disciplinary requirements of the institution, the authorized methods of seeking information and making complaints, and all such other matters as are necessary to enable him to understand both his rights and his obligations and to adapt himself to the life of the institution. (2) If a prisoner is illiterate, the aforesaid information shall be conveyed to him orally. This requirement is confirmed in principle 13 of the Body of Principles for the Protection of All Persons under Any Form of Detention or Imprisonment. Subsequent principles include the following provisions: Promptly after arrest and after each transfer from one place of detention or imprisonment to another, a detained or imprisoned person shall be entitled to notify or to require the competent authority to notify members of his family or other appropriate persons of his choice of his arrest, detention or imprisonment or of the transfer and of the place where he is kept in custody. [principle 16, para. 1] If a detained or imprisoned person is a foreigner, he shall also be promptly informed of his right to communicate by appropriate means with a consular post or the diplomatic mission of the State of which he is a national or which is otherwise entitled to receive such communication in accordance with international law or with the representative of the competent international organization, if he is a refugee or is otherwise under the protection of an intergovernmental organization. [principle 16, para. 2] If a detained or imprisoned person is a juvenile or is incapable of understanding his entitlement, the competent authority shall on its own initiative undertake the notification referred to in the present principle. Special attention shall be given to notifying parents or guardians. [principle 16, para. 3] A detained or imprisoned person shall be entitled to communicate and consult with his legal counsel. [principle 18, para. 1] A proper medical examination shall be offered to a detained or imprisoned person as promptly as possible after his admission to the place of detention or imprisonment, and thereafter medical care and treatment shall be provided whenever necessary. This care and treatment shall be provided free of charge. [principle 24] The guarantee provided in principle 16, paragraph 2, of the Body of Principles was also incorporated in the 1963 Vienna Convention on Consular Relations (art. 36, para. 1 (b)). 42
