UNIDROIT Principles of International Commercial ContractsLink to the English version of the UNIDROIT Principles of International Commercial Contracts. This link is to the 2016 edition.
the 2016 edition of the UNIDROIT Principles, like the 2010 edition, consists of 211 Articles (as opposed to the 120 Articles of the 1994 edition and the 185 Articles of the 2004 edition) and covers virtually all the most important topics of general contract law. For ease of comparison, the 2016 edition contains a table of correspondence of the articles of the four editions.
The main objective of the fourth edition of the UNIDROIT Principles is to take better into account the special needs of long-term contracts. To do so, the content of the 2010 edition has been altered only marginally: only six provisions have been amended, i.e. the Preamble and Articles 1.11, 2.1.14, 5.1.7, 5.1.8, and 7.3.7. Indeed, the majority of alterations were made to the Comments, in particular on the Preamble (amendments to Comment 2) and Articles 1.11 (addition of a new Comment 3), 2.1.14 (amendments to Comments 1-3 and addition of a new Comment 4), 2.1.15 (amendments to Comment 2 and addition of a new Comment 3), 4.3 (amendments to Comment 3 (which has become Comment 4) and addition of a new Comment 3), 4.8 (amendments to Comments 1-3), 5.1.3 (amendments to the Comment (which has become Comment 1) and addition of a new Comment 2), 5.1.4 (addition of a new Comment 3), 5.1.7 (amendments to Comments 2-3), 5.1.8 (amendments to the Comment (which has become Comment 1) and addition of a new Comment 2), 7.1.7 (addition of a new Comment 5), 7.3.5 (amendments to Comment 3 and addition of a new Comment 4), 7.3.6 (amendments to Comment 1), and 7.3.7 (amendments to Comments 1-2).
