(122)Directive 89/665/EEC provides for certain review procedures to be available at least to any person having or having had an interest in obtaining a particular contract and who has been or risks being harmed by an alleged infringement of Union law in the field of public procurement or national rules transposing that law. Those review procedures should not be affected by this Directive. However, citizens, concerned stakeholders, organised or not, and other persons or bodies which do not have access to review procedures pursuant to Directive 89/665/EEC do nevertheless have a legitimate interest, as taxpayers, in sound procurement procedures. They should therefore be given a possibility, otherwise than through the review system pursuant to Directive 89/665/EEC and without it necessarily involving them being given standing before courts and tribunals, to indicate possible violations of this Directive to a competent authority or structure. So as not to duplicate existing authorities or structures, Member States should be able to provide for recourse to general monitoring authorities or structures, sectoral oversight bodies, municipal oversight authorities, competition authorities, the ombudsman or national auditing authorities.
