PURPRESTURE. According to Lord Coke, purpresture, is a close or enclosure, that is, when one encroaches or makes several to himself that which ought to be in common to many; as if an individual were to build between high and low water-mark on the side of a public river. In England this is a nuisance; and in cases of this kind an injunction will be granted, on ex parte affidavits, to restrain such a purpresture and nuisance. 2 Bouv.
