Black's Law Dictionary
To obtain by application; to petition for and take out. Properly the term is applied only to the obtaining and issuing of such process as is only accorded upon an application first made; but conventionally it is also used of the taking out of process which issues of course. The term is occasionally used of instruments other than writs. Thus, we speak of "suing out" a pardon.
