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 contract is awarded, they would be required to be either natural or legal persons.

Legal persons may be required to indicate, in the tender or in the application, the names and relevant professional qualifications of the staff to be responsible for the performance of the contract in question.

2. Groups of economic operators, including temporary associations, may participate in concession award procedures. They shall not be required by contracting authorities or contracting entities to have a specific legal form in order to submit a tender or a request to participate.

Where necessary, contracting authorities or contracting entities may clarify in the concession documents how groups of economic operators shall meet the requirements as to economic and financial standing or technical and professional ability referred to in Article 38 provided that this is justified by objective reasons and is proportionate. Member States may establish standard terms for how groups of economic operators are to meet those requirements. Any conditions for the performance of a concession by such groups of economic operators, which are different from those imposed on individual participants, shall also be justified by objective reasons and shall be proportionate.
