Da delimitação entre atos preparatórios e atos de execução no Iter Criminis: a teoria do ato produtor da finalidade como evolução da teoria objetivo-individual do início de execução

Abstract

This work aims to verify conceptually the meaning of the expression execution acts, as opposed to preparation acts, in the context of the theory of criminal attempt and iter criminis. The research was based on the theory of reductionist functionalism, as proposed by Eugenio Raúl Zaffaroni in his most recent works. During the research, the most important theories about the meaning of the execution acts have been analyzed and criticised. After the analisys, became evident that none of the theories offers a perfect concept. It has been concluded that Nelson Pessoa’s purpose producing act theory is the one that gets closer to the ideal of legal certainty.
