Jedan od najpoznatijih i najuspješnijih instrumenata za ostvarivanje predvidljivosti i uniformnosti trgovačkog ugovornog prava jeste Konvencija Ujedinjenih Nacija o ugovorima o međunarodnoj prodaji robe, koja je usvojena na diplomatskoj konferenciji u Beču 1980. godine, a stupila na snagu 1988. godine, i koju je do sada ratificiralo 89 država svijeta. Ona sadrži materijalnopravne propise o pitanjima koja se tiču ugovora o prodaji između subjekata koji imaju sjedište u dvije različite države, a činjenica da ju je ratificiaralo devet od deset najvećih svjetskih izvoznika i uvoznika, te da se primjenjuje na oko 80% ugovora o međunarodnoj prodaji robe, govori o njezinom značaju. Konvencija propisuje složen sistem za raskid ugovora vodeći se principom očuvanja ugovora na snazi dok je god to moguće, tako da na prvi pogled djeluje iznenađujuća mogućnost raskida ugovora prije dospijeća ugovorne obaveze. Ipak, kada se uzme u obzir obim njezine primjene, onda ova mogućnost djeluje sasvim logična, a sve u cilju izbjegavanja bespotrebnih troškova. U radu su prezentovana rješenja Konvencije koja se odnose na pravo kupca na raskid ugovora prije dospijeća ugovorne obaveze, odnosno način, postupak i uslovi koji pri tome moraju biti ispoštovani.; One of the best known and successful instruments for achieving predictability and uniformity in contractual commercial law is the United Nations Convention on the Contracts for the International Sale of Goods which was adopted at the Diplomatic Conference in Vienna in 1980 and entered into force in 1988. The Convention has been ratified by 89 states. It contains substantive rules on matters relating to sales contracts between entities having their headquarters in two different countries. The fact that it has been ratified by nine of the world's ten largest exporters and importers and that it applies to about 80% of the international sale of goods contracts is a sufficient indication of its significance. The Convention prescribes a complex system for termination of contracts taking into account the principle of preservation of the contract as long as possible, so that at first sight there is a surprising possibility of termination of the contract prior to the date of performance. However, if we consider its application, this solution is logical in order to avoid unnecessary costs. The paper presents the solutions of the Convention relating to the right of the buyer to terminate the contract prior to the date of performance of the contract, i.e. the manner, procedure and conditions that must be respected.
