Author Description

First place, in this work the way of scientific investigation is cleared, based always in a plural scientific approach with a strong link to systematic and integrative methods towards various species of science. The first chapter deals with the clarification of the general premises of the work, based on law as a linguistic phenomenon, studied by Language Theories, Law Logics (aggregated on logic-semantic constructivism) and Niklas Luhmann s System s Theory. In the second chapter, avoidance and anti-avoidance rules are shown as general structures of law, in the lights of legal unity and System s Theory. The third chapter deals with the fractal and asymmetric classification of the anti-avoidance rules, adding an example of these rules outside the tax realm. The fourth chapter deals with the specificities of this new approach of the anti-avoidance tax rules and its developments and effects, analyzing also the differences to tax planning and tax evasion. The fifth and last chapter deals with anti-avoidance (especially its criteria) in different legal systems, such as in Brazil, Italy, USA and in international tax law, including the treaties to avoid double taxation and EC law.
