POUiQCK V. STEAM-BOAT LAUKA. 139 �only where the forfeiture is incurred without wllful negli- gence or intent to defraud. See original law on tbis subject, (St. 1797, c. 13; 1 St. 596.) Wbile tbis precise limitation is not imposed- on him in the present class of cases, yet, no doubt, bis power is to be exercised quasi judicially, and not as mere matter of grace, or arbitrarily, and witbout substan- tial grounds of equity and justice. It would, in my opinion, take from the statute a very important part of its beneficiai operation to hold that after suit brougbt by an informer in one of these cases like the present, -where the vi-bole penalty is given to him, the power. to remit or mitigate was gone.

This argument, however, proceeds upon a mis- take as to the meaning of the word "informer," The plain- tiff in a popular action is an "informer," as that word is understood in the law and used in the statutes of England and of this country. Thus Blackstone says, speaking of stat- utory penalties : "The usual application of these penalties or forfeitures is either to the party aggrieved, or else to any of thô queen's subjects in general.
