Practice Relating to Rule 151. Individual Responsibility
Section B. Individual civil liability
Luxembourg’s Law on the Punishment of Grave Breaches (1985) states that a civil action against the perpetrator of offences provided for in this law can only be undertaken before a civil court. However, it provides for the possibility for the (criminal) court to order the restitution of seized objects and exhibits to the entitled person if they are not to be confiscated.
