The European Commission has published an official notice concerning the opening up to the public of documents and files, from its historical archives, which are covered by professional or business secrecy obligations. Under the 30-year rule concerning the historical archives of the European Communities (the ECSC, the EEC and the EAEC), the Commission is required to open its archives to public access on a yearly basis. As a general rule, a file may be made open to public access after a period of 30 years even if it contains documents which were subject to professional or business secrecy obligations at the time they were originally lodged. Before disclosing such documents, however, the Commission is obliged to publish a notice of its intention to do so in the Official Journal of the European Communities. This is in order to allow the persons or firms concerned, or their successors, to lodge objections. The current notice covers the period 1952 to 1965 and relates to European Coal and Steel Community (ECSC) files. In the specific area of technical and scientific research (coal and steel), the only file to be released concerns a request from an Italian company (Società Italconsult SpA) for financial aid from the High Authority. This includes a description of the research projects submitted for funding and patents for inventions.
