(32)Public contracts awarded to controlled legal persons should not be subject to the application of the procedures provided for by this Directive if the contracting authority exercises a control over the legal person concerned which is similar to that which it exercises over its own departments, provided that the controlled legal person carries out more than 80 % of its activities in the performance of tasks entrusted to it by the controlling contracting authority or by other legal persons controlled by that contracting authority, regardless of the beneficiary of the contract performance. The exemption should not extend to situations where there is direct participation by a private economic operator in the capital of the controlled legal person since, in such circumstances, the award of a public contract without a competitive procedure would provide the private economic operator with a capital participation in the controlled legal person an undue advantage over its competitors. However, in view of the particular characteristics of public bodies with compulsory membership, such as organisations responsible for the management or exercise of certain public services, this should not apply in cases where the participation of specific private economic operators in the capital of the controlled legal person is made compulsory by a national legislative provision in conformity with the Treaties, provided that such participation is non-controlling and non-blocking and does not confer a decisive influence on the decisions of the controlled legal person. It should further be clarified that the decisive element is only the direct private participation in the controlled legal person. Therefore, where there is private capital participation in the controlling contracting authority or in the controlling contracting authorities, this does not preclude the award of public contracts to the controlled legal person, without applying the procedures provided for by this Directive as such participations do not adversely affect competition between private economic operators. It should also be clarified that contracting authorities such as bodies governed by public law, that may have private capital participation, should be in a position to avail themselves of the exemption for horizontal cooperation. Consequently, where all other conditions in relation to horizontal cooperation are met, the horizontal cooperation exemption should extend to such contracting authorities where the contract is concluded exclusively between contracting authorities.
