Questão jurídica principal
Whether the municipal taxi regulation provided a sufficient formal legal basis for a general ban on operating a taxi business
Decisão extraída
No. A municipal executive regulation cannot lawfully establish a licensing requirement for the taxi business itself as a severe restriction of economic freedom.
Fundamentação extraída
A licensing duty for exercising a profession is a serious interference requiring a formal statutory basis. The city regulation was enacted by the executive, so it could not support the general business ban.
