after stating the facts, delivered the opinion of the court.
The plaintiff contended in the court below, and renews the contention here, that the. plea of justification interposed by *46 the defendant for the acts complained of, the seizure and sale of the -property, having been stricken out, he is left defenceless in the action. That such would be the effect of the ruling if the declaration was one in form for an ordinary trespass may be conceded. But the rule that a justification to an alleged trespass, to avail, must be pleaded, does not apply here. The striking out of the plea did not remove the fact that the seizure and sale were made under proceedings which protected the officer of the government from personal liability, because in the declaration itself'his liability is charged upon a state of facts which shows that he acted in conformity with the law, and could not, therefore, be held responsible for the alleged invasion of the rights of the plaintiff in its enforcement.
When the assessment was certified to the collector, his duty in enforcing it was one which he could not refuse to perform. There was no discretion vested in him to revise or alter it in any respect. His duty was purely ministerial. In
Erskine
v.
Hohnbach,
The same doctrine was reasserted in protection of a collector of internal revenue in the subsequent case of
Haffin
v.
Mason,
No question is,raised as to the regularity in form of the assessment certified to the collector. It is assumed on both sides that it is not open to objection in that respect. The prin-' cipal point urged by the plaintiff in error is that the defendant should not have proceeded to enforce the assessment after the-action by the United States was commenced on the bond of the distiller to collect the same taxes. But it is plain that the officer had no discretion in the matter. He could not suspend or in any way delay the performance of the duty imposed upon him because the government may have judged it. proper to proceed for the same taxes by action, not only against the distiller, but against the sureties on his bond also. The government may have thought that the property which could be reached by the collector would prove inadequate to meet the amount claimed.. By instituting the action it did not waive its right to pursue any other remedies afforded by the law to *48 secure the payment of its claim. Nor could the collector consider whether in the pending action it might not be ultimately determined that the taxes were illegal which he was endeavoring to collect. He had completed his duty more than a year before that decision was rendered. Had the judgment of their illegality been pronounced before the enforcement of the assessment by the collector, and been brought to his notice, a different question might possibly be raised.
"What remedy the plaintiff may have for the loss of his property or for the. amount of the proceeds obtained on its sale, we are not called upon to determine in this case. There may be,- perhaps, a claim against the government. All that we decide is, that a liability cannot be fastened upon the collector, a ministerial officer, for the enforcement of an assessment for taxes regular on its face, made by the Commissioner of Internal Revenue. Of such an officer the law exacts unhesitating obedience to its process.
Judgment affirmed.
