A secret document which sets out a procedure for dealing with child sex abuse scandals within the Catholic Church is examined by Panorama.
Crimen Sollicitationis was enforced for 20 years by Cardinal Joseph Ratzinger before he became the Pope.
It instructs bishops on how to deal with allegations of child abuse against priests and has been seen by few outsiders.
Critics say the document has been used to evade prosecution for sex crimes.
Crimen Sollicitationis was written in 1962 in Latin and given to Catholic bishops worldwide who are ordered to keep it locked away in the church safe.
It instructs them how to deal with priests who solicit sex from the confessional. It also deals with "any obscene external act ... with youths of either sex."
It imposes an oath of secrecy on the child victim, the priest dealing with the allegation and any witnesses.
Breaking that oath means excommunication from the Catholic Church.
- Estas revelações estão a ser largamente comentadas no Reino Unido, a favor e contra o Papa, nos Estados Unidos, até mesmo em Espanha. Em Portugal a norma é um silêncio envergonhado, o tal oath of secrecy, uma espécie de ommertá... Algum dia teremos a oportunidade de ver em Portugal a repportagem do Panorama da BBC?
