Objectives: analyse the cooperative relationship programmes and mechanisms to guarantee the correct interpretation of tax legislation between administrations, in the field of international commercial transactions and investments. Methodology: study of APA programmes; comparative study of solutions adopted by some administrations in EU; some internal mechanisms to resolve dispute in tax law. Some case studies will be analysed.
