In the case provided for in article R. 5127-18, the public prosecutor notifies the interested party that the single sample is to be submitted for expert examination and informs him that he has three clear days to state whether he intends to exercise his right to appoint an expert. If this right is exercised, the two experts provided for in article R. 5127-22 and the third party provided for in article R. 5127-25 shall be appointed simultaneously within the time limit set by the investigating judge.
The three experts examine the single sample together. However, only one expert will be appointed if the person concerned has declared, before the expiry of the time limit provided for in the previous paragraph, that he or she will abide by the conclusions of the expert appointed by the judge.
