The topic of theses is liability for material defects in sales contract. The provisions relating to liability for material defects in the sales contract apply to majority of contracts against payment, except to those for which there are specific provisions in the Civil Obligations Act. The legislature has devoted a whole chapter to this matter , whereas these provisions cover 23 articles in Civil Obligations Act. Due to such an arrangement, we recognize the importance of these provisions, which are not only important for the contract of sale, but for the majority of the contracts against payment which include responsibility for material defects. Furthermore, the legislator has had fully accepted Directive 1999/44 / EC. Although Directive relates to the protection of consumers, the rules of the Directive have been implemented in our Civil Obligations Act and are valid as a general rule for all contracts against payment, regardless of the contracting parties status. In comparison to the previous 1978 Civil Obligations Act, the current Civil Obligations Act is improved and more comprehensive while governing the issue of liability for material defects. Firstly,that is evident in expanded number of situations and cases when responsibility for material defects exists. Secondly, in the higher level of contracting parties protection while requiring their right of liability for material defects, whether the parties are consumers or not. Also in the exclusion of liability for inspected goods if the customer is a consumer, and as well in the extension of the deadlines for demanding the right from responsibilities in relation to material defects
