The European Union (EU) and the Republic of Serbia have recognized the importance of SMEs and are developing accordingly the institutional framework of this sector. In the process of EU accession, Serbia has to fulfil political, economic and legal requirements by implementing systemic reforms of its legal system in order to align it with the EU acquis. Some of these requirements have a direct or indirect impact on SME regulations, to which our chapter has been dedicated within a series of our papers on developing the SME regulatory framework. This paper will try to present the importance of innovating legal development of these companies. Furthermore, modern concepts will be introduced together with very important tools of legal forms of SME organization. The intention is to clearly define specific legal goals of SMEs, expressed through targeted legal forms. The modern regulatory framework relating to SMEs should combine the existing solid theoretical base and innovative models from the practice.

Sažetak: "Life cycle costing"-LCC analiza predstavlja novu alatku u javnoj nabavci korišćenu od strane vlada država širom sveta, sa ciljem uspostavljanja održive javne nabavke. LCC se razmatra u svetlu napora Evropske unije da uspostavljanjem mehanizma održive javne nabavke promoviše zelenu gradnju, zaštiti životnu sredinu i uspostavi ekonomsku i socijalnu održivost. Posebna pažnja je posvećena javnoj nabavci građevinskih objekata imajući u vidu da je građevinska industrija najveći zagađivač životne sredine, ali i industriji koja zapošljava najveći broj ljudi na svetu. Takođe, u radu se analiziraju prednosti primene LCC analize, poteškoće u implementaciji i aktuelna zakonska regulativa na nivou Evropske unije, kao i Republike Srbije. Ključne reči: troškovi životnog ciklusa "LCC" analiza / održiva javna nabavka / zaštita životne sredine UVOD Održivi razvoj se bazira na prepoznavanju činjenice da kada se resursi troše brže nego što se stvaraju oni se troše do potpunog nestanka. Smanjivanje prirodnih resursa neizostavno vodi do povećanja cena, a samim tim i do povećanja siromaštva i opadanja kvaliteta života. Svaka odluka koja se donese u vezi sa nabavkom javnih

The effects of globalisation are many. One of them is the effect that globalisation has on commercial contracts and contractual relations between contracting parties. Due to a fast pace of economy and the speed and volume of the conclusion of contracts in international trade, participants must rely on stable and reliable legal framework for contractual obligations. In globalised economy, traders from different countries bring with them individual trade practices and norms of national legislation, often diametrically opposed, and sometimes the legal institutes that are regulated in one country don’t even exist in another. This is the case with the institutes of force majeure and a change of circumstances. Due to large differences in the regulation of these two institutes in national legal systems, there have been demonstrated some attempts of standardisation and creation of a unified system of exemption from liability for non-performance, due to force majeure or a change of circumstances. This problem becomes even more evident when dealing with the long term contracts, which are prone to the effects of unforeseen circumstances. This paper aims to explore the nature of the above mentioned legal institutes in some of the most important sources of international commercial law. With a special attention paid to the Serbian regulatory solutions, in order to further understand the similarities and differences between the national legal systems and sources of international law. The first part of the paper deals with applicable legal framework in Republic of Serbia, concerning force majeure and a change of circumstances. The second part of the paper deals with the international sources of commercial law, such as UN Convention on Contracts for the International Sale of Goods of 1980; UNIDROIT Principles of International Commercial Contracts; Principles of European Contract Law; Draft Common Frame of Reference; and Common European Sales Law.
