Peter Radan, an Australian legal academic, has criticised the Badinter Commission's interpretation of the SFRY Constitution. Apart from principles of international law, the Badinter Commission sought to justify the relevance of the Badinter Borders Principle by reference to article 5 of the 1974 Constitution of the Yugoslavia. The Commission said that the Badinter Borders Principle applies all the more readily to the Republics since the second and fourth paragraphs of Article 5 of the Constitution of the SFRY stipulated that the Republics’ territories and boundaries could not be altered without their consent.
