Define ‘criminal trespass’.

Criminal trespass is primarily defined as entering someone else’s property without permission and having the intent to commit an unlawful act. This definition encompasses not only unauthorized entry but also the purpose behind that entry. It indicates that the individual entered the property knowing they did not have permission and had some unlawful intention, which distinguishes it from merely being on the property without authorization.

The other choices do touch on aspects of property rights and unlawful behavior but do not accurately capture the legal definition of criminal trespass. Using property without paying for it could relate to theft or fraud but does not specifically address the notion of unauthorized entry. Refusing to leave when asked involves trespass but lacks the requirement of entry, indicating that someone may have had permission to be there initially, which complicates the definition of trespass. Damaging property pertains to vandalism or destruction but does not involve the act of entering someone's property, which is a critical element of criminal trespass. Thus, the correct answer reflects the comprehensive understanding of what constitutes criminal trespass under the law.
