In its judgment of 6 June 2002 in Case C-159/00, Sapod Audic, the Court of Justice points out that, according to established case-law, the Directive laying down a procedure for the provision of information in the field of technical standards and regulations must be interpreted as meaning that a failure to observe the obligation to notify laid down in Article 8 of that Directive constitutes a substantial procedural defect such as to render the technical regulations in question inapplicable and thus unenforceable against individuals. Furthermore, the Court recalls that, according to its case-law, the inapplicability of a technical regulation which has not been notified to the Commission in accordance with Article 8 of the Directive may be invoked in legal proceedings between individuals concerning, inter alia, contractual rights and duties.
