Bilous O. Unification and comparative analysis of the Contract Law in scopes of the UNIDROIT Principles

The dissertation aims to prove that the UNIDROIT Principles of International Commercial Contracts should be recognized as Uniform Contract Law. Since its adoption in 1994 this document was considered to be a source of the lex mercatoria. The introduction to the dissertation raises a suggestion that the UNIDROIT Principles were called 'of international commercial contracts', only because international trade was the sphere of social life that emerged this regulation, but it doesn't mean that the Principles represent 'international commercial law', they are General Principles of Contract Law and they may regulate any contract: domestic or non-domestic, commercial or civil one.
