Questão jurídica principal
Whether the contribution assessment for 2000 could be made under the extraordinary procedure because of a lasting qualitative change in income basis and a causal income increase.
Decisão extraída
Yes. The formation of the collective partnership created a new income source through profit participation, the change was lasting, the income increase exceeded 25%, and causation was established.
Fundamentação extraída
The court held that the relevant change was not mere cost-sharing, but a new income basis arising from partnership membership and profit sharing; the extraordinary procedure was therefore permissible under the applicable AHVV rules.
