This contribution is based on a national report for the XVIIth International Congress of Comparative Law written by the author in 2006. The text is accompanied by author's introduction and footnote commentary regarding further developments that have taken place in Serbian law since then. The author discusses the permissibility in Serbian Private International Law of clauses exempting the contract from the application of any law or subjecting it to the application of non-State rules of law. The analysis begins with the expression "le contrat sans loi" and the various meanings ascribed to it. The limits to party autonomy, namely, the possibility for the parties to select non-State rules of law or to exclude any law whatsoever, are outlined in Chapter 2. In this chapter the author discusses the permissibility of such agreements, the requirements for the formulation of choice, and possible limitations to the choice of non-State rules of law. In Chapter 3, the author examines the question of whether the courts and arbitrators can designate non-State rules of law in the absence of the parties' choice. The recognition of foreign judgments and arbitral awards based on the application of non-State rules of law is discussed in Chapter 4. The author draws certain conclusions as to the current state of Private International Law in Serbia regarding contracts with no governing law.
