II. Purposes for which an advocate way he employed.

1. To secure justice, in case any question involving justice is to be tried.

2. To defend the accused. If one has been accused of committing a crime, an advocate may be employed to conduct his trial on his behalf; to defend him against the charge, and prevent his conviction if possible.

3. An advocate may be employed to secure a pardon, when a criminal has been justly condemned, and is under sentence. That is, an advocate may be employed either to secure justice for his client, or to obtain mercy for him, in case he is condemned; may be employed either to prevent his conviction, or when convicted, may be employed in setting aside the execution of the law upon the criminal.
