Principio da Capacidade Contributiva

• The application of this principle requires balancing it with other involved principles. (p. 42-46, Carrazza)

• Celso Antônio Bandeira Mello defines the principle as the nuclear foundation of the legal system, irradiating over different norms and providing them with coherence and harmony. (p. 68, Mello)
