1. Economic operators that, 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 concession is awarded, they would be required to be either natural or legal persons.
2. However, legal persons may be required to indicate in the tender or the application, the names and relevant professional qualifications of the staff to be responsible for the performance of the concession in question.
3. Groups of economic operators may submit tenders or put themselves forward as candidates.
4. Contracting authorities and contracting entities shall not establish specific conditions for participation of such groups in concession award procedures which are not imposed on individual candidates. In order to submit an application or a tender, these groups shall not be required by the contracting authorities or contracting entities to assume a specific legal form.
Contracting authorities and contracting entities may establish specific conditions for the performance of the concession by a group, provided that those conditions are justified by objective reasons and proportionate. Those conditions may require a group to assume a specific legal form once it has been awarded the contract, to the extent that this change is necessary for the satisfactory performance of the concession.
