Understanding the Role of the Constitution in Criminal Law

Introduction to Legal Principles

• Professor Márcio Caldas introduces the topic, focusing on general criminal law theory and referencing previous discussions about the Penal Code.

• The principle of legality is highlighted, emphasizing that there can be no crime without a prior law defining it and no punishment without legal provision.

Can the Constitution Define Crimes?

• A question is posed regarding whether the Federal Constitution can classify conduct as a crime without specific laws stating so.

• Although one might think that since the Constitution holds supreme authority, it could define crimes, prevailing opinion suggests otherwise.

Legislative Process and Constitutional Limitations

• The rigidity of constitutional amendment processes is discussed, indicating challenges in adapting to new types of crimes or refining existing laws.

• Examples are provided where the Constitution issues mandates for criminalization (e.g., racism), guiding ordinary legislators on how to define these crimes.

Parameters for Ordinary Legislation

• Specific articles (5º incisos 42, 43, 44) illustrate how the Constitution sets parameters for legislating certain crimes like torture and drug trafficking.

• It is emphasized that while these articles provide guidelines for legislation, they do not explicitly define what constitutes each crime or their penalties.

Complementary Laws and Their Status

• Discussion shifts to whether complementary laws can establish criminal definitions; however, such laws may only hold ordinary status under constitutional scrutiny.

• The distinction between complementary and ordinary laws is clarified: even if a law follows proper legislative procedures, it may not achieve complementary status if it pertains to criminal law.
