Abstract
Selection of the most favourable offer on the basis of carefully selected tender evaluation criteria affects the effectiveness of public spending. Practical analyses confirm dubitable effectiveness of selection and application of other than price evaluation criteria. The difficulties which arise in practice are due to problems with setting appropriate proportions of weights for non-price criteria due to no reliable identification of the needs of the contracting authority and lack of expertise of people responsible for their elaboration. The problems of practical application of non-price evaluation criteria have not been resolved by the introduction of the mandatory limit of other than price criteria since the literal application of legal regulations in force negatively affects observance of the rules of effective public procurement awards. It seems that in order to improve the situations it is necessary to amend the existing regulations as regards liberalization of the mandatory limit of non-price criteria as well as to develop a standard methodology for selecting rational evaluation criteria depending on the object of procurement. It is also important for the people who draw documents for public procurement proceedings to have suitable qualifications, expertise and experience as regards knowledge of the object of procurement.
