In the mid 1990’s work started to introduce a true non-punitive reporting system in the Kingdom of Denmark, including Greenland and the Faroe Island. In 2001 an amendment to the Danish Aviation Act passed through the Danish Parliament introducing a mandatory occurrence reporting scheme and at the same time ensuring, that the person filing a mandatory report, can not be prosecuted nor punished for what he or she reports. On the contrary, they will only be prosecuted if they do not report occurrences that are comprehended by the legislation. The mandatory reporting also includes occurrences caused by intend or even gross negligence. Reports will only be known to very few authority persons who according to the Danish criminal code, will be prosecuted if they reveal any information which enables the identification of the originator of the report. Around 3,000 reports are on a yearly basis stored in a special designed data base.
