Abstract:
The present work seeks to understand the systematic of the principles of law, highlighting the principle of insignificance that has been gaining prominence in the Brazilian criminal legal scenario, although not yet expressly provided for in the Brazilian legal system, has been constantly applied by jurisprudence, which, materially considers conduct that, although formally provided for in the criminal law, is not sufficiently harmful to achieve the legal good under the norm. This is because, as the concept of penal types is abstract, it cannot be avoided that they have a wider range than anticipated. The application of this principle aims to provide greater speed, procedural economy and the effective application of penalties that actually achieve the goals for which the laws are created. Thus, for its elaboration, doctrinal and jurisprudential researches were carried out, as well as articles published on legal websites.
