Questão jurídica principal
Whether the AML supervision fee required a specific constitutional basis and violated legality principles.
Decisão extraída
The Federal Court did not finally decide the constitutional question; under Art. 190 Cst. it had to apply Art. 22 LBA and reject the challenge.
Fundamentação extraída
Even if the fee may be viewed as a special levy or tax-like contribution, the Court held that constitutional doubts could not be reviewed away in the concrete case because Art. 22 LBA is binding.
