Candidates or tenderers who, under the law of the Member State in which they are established, are entitled to provide the relevant service, shall not be rejected solely on the ground that, under the law of the Member State in which the contract is awarded, they would be required to be either natural or legal persons.

However, in the case of public service and public works contracts as well as public supply contracts covering in addition services and/or siting and installation operations, legal persons may be required to indicate in the tender or the request to participate, the names and relevant professional qualifications of the staff to be responsible for the performance of the contract in question.

Groups of economic operators may submit tenders or put themselves forward as candidates. In order to submit a tender or a request to participate, these groups may not be required by the contracting authorities to assume a specific legal form; however, the group selected may be required to do so when it has been awarded the contract, to the extent that this change is necessary for the satisfactory performance of the contract.
