When is an action considered trespassing under Penal Code 602 M?

An action is considered trespassing under Penal Code 602 M when a person occupies real property without the consent of the owner. This legal definition emphasizes the importance of the owner's rights over their property; any unauthorized entry or occupation is a violation of those rights. Trespassing can occur even if no damage is done, as the mere act of entering or remaining on someone else's property without permission constitutes an infringement on the owner's legal authority.

In contrast, the other options center around situations where permission is granted. When an owner invites someone onto their property, or when permission is obtained prior to entry, these actions do not fall under the definition of trespassing. Thus, the distinction lies in the lack of consent from the property owner, which is fundamental to understanding what constitutes trespassing within the legal framework.
