What is the doctrine of attractive nuisance?

One who maintains on his estate or premises an attractive nuisance without exercising due case to prevent children from playing therewith or resorting thereto, is liable to a child of tender years who is injured thereby, even if the child is technically a trespasser in the premises. (Jarco Marketing Corp. v. CA, 117 SCAD 818, 321 SCRA 375 (1991), Paras, p. 741)
