The power of equity courts to grant injunctions against trespass to real property, long denied, is now acknowledged. The exercise of this power, however, is generally confined to the following classes of cases:

(a) Where the trespass would inflict irreparable damage.

(b) Repeated trespasses.8

(c) Where the trespasser is financially irresponsible.

An injunction will generally be refused where the plaintiff is out of possession, and the defendant in possession under a claim of right.9
