Questão jurídica principal
Whether the challenged neighborhood interference qualifies as immissions under Art. 684 ZGB rather than a direct ownership attack under Art. 641 ZGB
Decisão extraída
The balls and players are indirect consequences of the use of the neighboring field and therefore fall under Art. 684 ZGB.
Fundamentação extraída
The interference is not a direct intrusion into the plaintiffs' land but a side effect of using the school field; direct trespass concerns only the players who physically enter the land.
