Ad quod damnum is a writ which ought to be sued before the king grants certain liberties, as a fair, market, or such like, which may be prejudicial to others, and thereby it should be inquired whether it will be a prejudice to grant them, and to whom It will be prejudicial, and what prejudice will come thereby. There is also another writ of ad quod damnum, if any one will turn a common highway and lay out another way as beneficial. Terines de la Ley.
