The death of Nazi criminal Erich Priebke in Rome made the Italian and Canon rules about funerals and cemeteries suddenly very important.
On the Church side, the Vicariate of Rome made known that Mr Priebke will only get private prayers in the house where the body is kept. This order is binding for every priest in the Diocese of Rome.
On the Italian side things are obviously messier. There is a Death Hygiene Regulation dating back to 1990, and apparently the Municipality of Rome and the Prefecture are having a hard time in ensuring that Mr Priebke doesn’t get civil funerals or a burial in the city.
