(9)The good repute of transport managers is conditional on their not having been convicted of a serious criminal offence or not having incurred a penalty, for a serious infringement, in particular, of Community rules relating to road transport. A conviction or penalty incurred by a transport manager or a road transport undertaking in one or more Member States for the most serious infringements of Community rules should result in the loss of good repute provided that the competent authority has ascertained that a duly completed and documented investigation procedure granting essential procedural rights took place before its final decision and that appropriate rights of appeal were respected.
