Does intentionally driving a stray horse into B's pasture constitute trespass?

Intentionally driving a stray horse into B's pasture constitutes trespass because trespass is defined as entering or causing another to enter onto another’s land without permission. In this scenario, A has deliberately caused the horse to enter B's property. The critical element of intent is satisfied because A made a conscious decision to drive the horse into the pasture, which directly interferes with B's possessory rights over the land.

Even though A may own the horse, ownership does not grant the right to unilaterally decide where the horse can roam, especially if it involves entering someone else's property without consent. The act of trespass is focused on the action taken regarding the land itself rather than the ownership of the animal involved.

Additionally, the occurrence of damage to B's property or the nature of the act (whether it is one of negligence or intentional wrongdoing) is not necessary to establish a claim for trespass. The essence of trespass lies in the unauthorized entry itself, which has occurred here.

Thus, A's actions meet the criteria for trespass, supporting the assertion that the correct answer is that A has trespassed by driving the horse into B's pasture.
