The court find that there is no warrant for the issuance of a writ of prohibition sought by the plaintiff, for the reason that the action, order and judgment which the plaintiff seeks to have restrained and prohibited have been fully consummated. A writ of prohibition may be awarded only to prevent' the unlawful usurpation of jurisdiction, and does not lie to prevent the enforcement of a claimed erroneous judgment previously rendered; it may be invoked only to prevent proceeding in a matter in which there is an absence of jurisdiction and not to review the regularity of an act already performed. It cannot be substituted for a proceeding in error. '

Writ denied.
