OBS_VALUE: The Italian legislature recently issued a New Public Contract Code. This  is meant to simplify the regulatory style, and introduce new general principles of efficiency and effectiveness of administrative action (Art.10-11). According to the provisions of Art.50 of the new Public Contract Code, operators must be chosen according to objective criteria and based on principles of non-discrimination, proportionality and transparency. Except when international agreements apply, the foreign suppliers' offer can be refused if more than 50% of the products comes from third countries (article 137(2), 16).
