Contraventions are proven either by minutes or reports, or by witnesses in the absence of reports and minutes, or in support of them.
Except in cases where the law provides otherwise, minutes or reports drawn up by officers and agents of the judicial police and deputy judicial police officers, or officials or agents entrusted with certain functions of the judicial police to whom the law has assigned the power to record contraventions, are authentic until proven otherwise.
Proof to the contrary may only be provided in writing or by witnesses.
