What defines a ‘trespasser’ according to the legal context within these cases?

In the context of trespass under Irish law, a ‘trespasser’ is defined as any individual who enters private property without explicit permission from the property owner or lawful occupant. This definition is rooted in the legal principle that every property owner has the right to control access to their property and to determine who may enter or remain on it.

When someone enters a property without the owner’s consent, they disrupt that fundamental right, thereby constituting a trespass. This broad definition emphasizes the importance of explicit permission, which can be either verbal or written, and implies that simply lacking permission renders an entry unlawful, regardless of the individual's intentions or reasons for entering.

While the other options touch on related concepts, they do not capture the comprehensive definition utilized in legal terms. For example, a person who has been previously invited but no longer has permission could certainly be termed a trespasser, but this scenario is just one instance of a broader concept. Similarly, the mention of minors or guests who overstay their welcome introduces additional layers of complexity that are not central to the core legal definition of trespassing as it is primarily concerned with the absence of permission. Thus, the focus remains firmly on the individual's lack of explicit permission to be on the property in question
