10. Any enterprise or natural person who has, in any capacity, participated in fraud or fraudulent tactics in the course of the tendering, awarding or management of a public contract is presumed to have caused injury to the public body concerned.
In such a case, the officers of the enterprise in office at the time the fraud or fraudulent tactics occurred are held liable unless they prove that they acted with the care, diligence and skill that a prudent person would have exercised in similar circumstances.
The directors of the enterprise in office at the time the fraud or fraudulent tactics occurred are also held liable if it is established that they knew or ought to have known that fraud or fraudulent tactics were committed in relation to the contract concerned, unless they prove that they acted with the care, diligence and skill that a prudent person would have exercised in similar circumstances.
The enterprises and natural persons referred to in this section are solidarily liable for the injury caused, unless such liability is waived by the public body.
