The seminary is articulated into two parts. During the first part will focus on the legal instruments that the tax-payer can ensure to put forward his arguments against the charges of tax law breach by the Tax Autority, also in the context of the non-judicial instruments of dispute resolution (like the verification with acceptance and mediation procedures). During the lessons will take place some simulations of these procedures and will be examined and written some examples of the connected deeds and documents. The second part of the course I dedicated to the study of the tax trial (introductory phase, investigation phase, decision phase). There will be a simulation of some trial activities and the students will be provided with some judicial deed models.
