A contracting entity must verify the conditions for participation relating to the professional and technical ability and the financial and economic standing of candidates or tenderers on the basis of self-declarations or references submitted as proof in accordance with the requirements specified in the concession notice.

Those requirements must be non-discriminatory and proportionate to the subject-matter of the concession contract.

The conditions for participation must be related and proportionate to the need to ensure the ability of the concessionaire to perform the concession contract, taking into account the subject-matter of the concession contract and the purpose of ensuring genuine competition.

For the purpose of meeting the conditions for participation, an economic operator may, if appropriate and for a particular concession contract, rely on the capacities of other entities, regardless of the legal nature of its links with them, subject to the following provisions of this regulation.

If an economic operator wants to rely on the capacities of other entities, it must prove to the contracting entity that it will have at its disposal, throughout the period of the concession contract, the necessary resources; for example, by producing a commitment by those entities to that effect.

With regard to financial standing, the contracting entity may require that the economic operator and those entities on which it relies are jointly liable for the execution of the contract.

A group of economic operators referred to in regulation 29 (economic operators) may rely on the capacities of participants in the group or of other entities, and paragraphs (4) to (6) apply in relation to such a group in the same way that they apply in relation to an economic operator.
