DE NOVI OPERIS NUNCIATIONE, Civil law. Where a thing is intended to be done
against another man's right, the party aggrieved may have in many cases,
according to the civilians, an interdict or injunction, to hinder that
which is intended to his prejudice: as where one buildeth an house contrary
to the usual and received form of building to the injury of his neighbor,
there lieth an injunction de novi operis nunciatione, which being served,
the offender is either to desist from his work or to put in sureties that he
shall pull it down, if he do not in a short time avow, i. e. show, the
lawfulness thereof. Ridley's Civ. and Eccl. Law, part 1, chap 1, sect. 8.
