With the introduction in 2009 of a procurement review mechanism in ESA's Procurement Regulations, Member States together with the Director General have once more reemphasised the importance for ESA to carry out its procurements within the prevailing principles of transparency, impartiality and non-discrimination.
Central to an independent monitoring of these principles is the role of the ESA Industrial Ombudsman. The Ombudsman's role initially limited to the resolution of matters arising between Industries in the pre-contractual phase of procurements carried out by Prime Contractors in the frame of the so-called "BEST PRACTICES" has been extended, with the introduction of the procurement review procedure, to the resolution of claim alleging procedural breach of the Procurement Regulations by the Agency itself. The current mandate of the ESA's Ombudsmen will expire end 2012. In this respect, ESA in collaboration with its Member States and industry is seeking high-profile candidates for the position of the ESA's official Ombudsman and his/her alternate as described in the Announcement of Opportunity.
