Questão jurídica principal
Whether the ordered periodic checks of the pig count were lawful and proportionate.
Decisão extraída
The control measures were lawful because authorities must ensure compliance with the emission-related maximum stocking limit; periodic unannounced checks were permissible given the layout and realistic possibility of exceeding the limit.
Fundamentação extraída
The court held that the minimum distances under the air pollution rules can be respected only if the barn 2 stock is limited to 580 piglets. Since the barn could still hold more animals even after modifications, the municipality was entitled to order checks to secure compliance.
