EVIDENCE
Article 127. The expert's opinion
127.1. The expert’s opinion, expressed in written form and based on his specialised knowledge of scientific, technical, artistic or professional fields, shall consist of :
127.1.1. his findings on the questions put to him by the prosecuting authority or the parties to the criminal proceedings, as well as on the investigation of other matters relating to his competence which emerge during the examination of the case file ;
127.1.2. a description of the investigation carried out by the expert to substantiate those findings.

127.3. The expert's opinion shall not be binding on the preliminary investigator, investigator, prosecutor or court; it shall be checked by the prosecuting authority in the same way as any other evidence and evaluated in the light of all the relevant facts.

128.3. The significance of an item as material evidence shall be accepted by the court if :
128.3.1. immediately after its acquisition, the item is described in detail and sealed, and other similar acts are carried out making it impossible significantly to alter the imprints it bears and its features or characteristics ;
