As part of an operation to monitor the routing or transport of objects, goods or products derived from the commission of a customs offence or used to commit a customs offence, where the prison sentence incurred is equal to or greater than two years, and where the needs of the investigation so require, customs officers authorised by the Minister responsible for customs under conditions laid down by decree may, throughout the national territory, with the authorisation of the public prosecutor at the judicial court in whose jurisdiction the surveillance operations are likely to begin, deliver or issue these objects, goods or products in place of postal service providers and freight operators, without being held criminally liable.
On pain of nullity, the public prosecutor’s authorisation shall be in writing and substantiated. This authorisation shall be placed in the case file and the acts authorised may not constitute incitement to commit an offence.
