You should be able to maintain your family and private relationships and create new ones by communicating with people outside the prison. This means that you have the right to write letters or call your family, friends, journalists, acquaintances and even relative strangers. This right may be restricted only where allowed by law.
It is prohibited to restrict your right of correspondence or use of telephone for communication with state agencies, local governments or their officials or with the prisoner's criminal defence counsel or a representative who is an advocate.
Privileged correspondence
Certain correspondence is considered privileged, because it requires very serious reasons for it to be interfered with in any way. It is prohibited to examine the contents of your letters and telephone messages to a criminal defence counsel, representative who is an advocate, prosecutor, court, the Chancellor of Justice or the Ministry of Justice. It is prohibited to refuse to forward your letters to state agencies, local governments and the officials thereof, to criminal defence counsels and representatives who are advocates and consular officers of prisoner's country of nationality.
