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 public service and public works contracts as well as public 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 to be 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 authorities to have a specific legal form in order to submit a tender or a request to participate.

Where necessary, contracting authorities may clarify in the procurement documents how groups of economic operators are to meet the requirements as to economic and financial standing or technical and professional ability referred to in Article 58 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.
