Alias, in law, a second name. When a party sues or is sued (generally the latter) by two names, he is described as A---- B---- alias C---- D----. Some fine-drawn arguments were once extant as to the possibility of a man having a second name. But in modern times, with the facilities of wisely amending in judicial proceedings, the name of the individual is less important, provided the actual party is before the court. In an indictment for murder the name of the deceased is obviously of the very highest importance, the whole question turning on the identification as well of the murdered as of the murderer.
