Children are fearless and sometimes get injured when playing on someone else’s property. Typically, there are three kinds of people injured on property: an invitee, a licensee, and a trespasser. An invitee is basically a store customer for whom a landlord owes a higher level of protection; a licensee is a social guest at a house and is entitled to moderate protection; and a trespasser is on property without consent and is owed only minimal protection. However, as the court of appeals held in this case, an otherwise trespassing child who enters property because of an attractive nuisance is “invited” by the nuisance, and owed the protection of an invitee. But the attractive nuisance doctrine only applies to trespassing children. So a child “licensee” cannot rely on the doctrine. The court found the scheme constitutional because it is rational to give children higher protection.
