Princípio da legalidade, direitos fundamentais e máxima da proporcionalidade : análise da obrigatoriedade de submissão ao exame de DNA no ordenamento jurídico-penal brasileiro

Abstract

This dissertation focuses on the utilization of the DNA testing without the consent of the accused as an identification technique in Brazilian criminal law. Therefore, it begins studying the principle of legality, which applies as a guarantee of the citizens to not be compelled to do or refrain from doing anything except by virtue of law, analyzing its effects on the proof theory. Are taken into account also the fundamental rights raised by the jurisprudence that may be involved in this case in order to seek the factual support of these standards in light of the theory of principles. The proportionality test serves to verify the constitutional conformation of the utilization of a measure that restricts fundamental rights that is necessary to obtain genetic material, besides indicating the prerequisites and terms applied to appreciation of the measure. Utilizing literature, case law and legal review to consider the issues proposed, this text investigates the possibility of introducing in the Brazilian criminal law the bodily interventions required to utilize the DNA exam fully, even when the accused refuses to allow the extraction of the necessary materials.
