Questão jurídica principal
Whether the proportional stamp duty on the transfer of shares in a real-estate company violated equality because of alleged non-enforcement of other taxable acts.
Decisão extraída
No. The appellant failed to show a constant practice of non-enforcement in comparable cases or that he was in a truly similar situation to the cited examples.
Fundamentação extraída
Equality in illegality is exceptional and requires constant unlawful practice, an intention to persist, and no overriding public interest in legality. The examples invoked concerned different legal situations, mainly movable property or other categories. The court also held that practical enforcement difficulties do not prove deliberate non-application of the law.
