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.

However, in the case of service and works contracts as well as supply contracts covering in addition services 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 responsible for the performance of the contract in question.

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

Where necessary, contracting entities may clarify in the procurement documents how groups of economic operators are to meet the criteria and requirements for qualification and qualitative selection referred to in Articles 77 to 81 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 contract 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.
