delivered the opinion of the court.

Importers who have paid duties under protest • in writing may, if the duties were illegally exacted and the protest sets forth, distinctly and specifically, the grounds of the objection to the payment, maintain an action of assumpsit against the collector-to recover back the amount so paid. 5 Stat. 727.

Persons importing merchandise are required to make their protests distinct and specific, in order to apprise the collector of the nature of the objection, before it is too late to remove it, or to modify the exaction, and that the proper officers of’the treasury may know what they have to meet, in case they'decide to exact the duties as estimated, notwithstanding the objection, and to expose the United States to the risk of litigation. Curtis’s Administratrix v. Fiedler, 2 Black, 461.

Payment of the duties having been made under protest in writing, the importers brought assumpsit against the collector to recover back the amount which they allege was illegally ■exacted. Service was made; and- both parties appeared, and, having-waived-a trial by jury, submitted the-case to the court’ upon an agreed statement of facts. Hearing was had; and the " court rendered judgment, in favor of the defendant, and the) plaintiffs sued out the present writ of error.

Goods were imported by the plaintiffs from Liverpool into the port of New York, a portion of which were described in the invoice as Ducape Eglington ties, which are manufactures of silk, and are used and known as neckties, and were valued in the invoice at a net valuation équivalent to $696 in gold coin. Another portion of the merchandise is described in the invoice as twill silk cut up, and is valued in the invoice at a net valuation' equivalent to $234.13, gold. Both parcels were part of the merchandise described- in the invoice as the contents of a case marked and numbered; and the statement is, that they were *150 entered for consumption by tbe plaintiffs, under the dutiable rate of sixty per cent ad valorem, other portions of the merchandise being placed in the entry respectively under the duti able rates of thirty, thirty-five, and fifty per cent ad valorem.

Sufficient appears to indicate that the goods were appraised as the agreed statement shows; that the local appraiser reported the neckties 'to the collector as silk scarfs, and the twill silk cut up as silk in pieces, and that both were subject to duty ¿t the rate of sixty per cent ad valorem. Pursuant to that report, the collector liquidated the duties at that rate ; and the' plaintiffs paid that rate of duty on the neckties and the silk cut up, on the entered valuation of the same, as before explained. Custom duties are payable in gold; and the-plaintiffs paid the amounts in that medium, and under protest in writing.

Subsequent to the passage of the act of the 3d of March, 1839, and before the passage of the act of the 26th of February, 1845, such a suit' against a collector to recover back duties as having • been illegally exacted could not be maintained, unless it was brought before the.collector placed the. monéy to the credit of the Treasurer of the United States. 4 Stat. 348; Cary v. Curtis, 3 How. 236.

Hardship and injústice resulted from that rule of decision; and-the Congress, by the later act, established a different rule, - and' provided to the effect that the importer may in such a case have such a remedy against the collector to recover back such duties, if he protested in writing at or before the payment of the duties, and set forth distinctly and specifically the-grounds of his objections to the payment of the same. 5 Stat. 727.

'Different forms of expression are employed in,later enactments, but all which are applicable to the .case before the. court are, except as to time, substantially to the same effect. 13 id. 214, sect. 14.

What is required by that act in respect to the matter' in question is that the importer, if ’ dissatisfied with the decision of the collector, shall give notice in writing to him on each 'entry, setting forth therein, distinctly and specifically, the grounds of his objection thereto; which, certainly, is not different -from what is required by the antecedent act. Nor is there any substantial difference in the- construction given by *151 the courts to the provision which contains that requirement. Instead of that, both acts referred to make it necessary that the protest shall be in writing; and the requirement is that thq importer shall set forth, distinctly and specifically, the grounds of his objections to the payment of the liquidated duty.

Unless the protest is made in writing, and is signed by the claimant within ten days aftet the ascertainment and liquidation of the duties, setting forth distinctly and specifically the grounds of objection to the payment, no action of the, kind against the collector can be maintained to recover back the duties as having been illegally exacted. Nor is it sufficient to object to the payment of any particular duty or amount of duty, and to protest in writing against- it; but the claimant must do more, as is evident from the words of the act of Congress. He must set forth in his protest the grounds upon which he objects, distinctly and specifically, the reason being, as ruled by Chief Justice Tarney, that the words of the act .requiring the protest are too emphatic to be overlooked in the construction of the provision. Mason v. Kane, Taney’s Dec. 177.

Mistakes and oversights will sometimes lead to irregular assessment, and the object of the requirement is to prevent a party," if he suffers the mistake or oversight to pass without notice, from taking advantage of it when it is too late to make the correction-, and to compél him to disclose the grounds of his objection at the time when he makes his protest.

Protests of the kind must contain a distinct and clear specification of each substantive ground of objection to the payment of the duties. Technical precision is .-not required; but the objections must be so distinct and specific, as, when fairly construed, to show that the objection taken at the trial was at the time in the mind of the importer, and that'it was sufficient to notify the collector of its true nature and character, to the end that he might ascertain the precise facts, and have an opportunity to correct the mistake and cure the defect, if it was one which could be obviated. Burgess v. Converse, 2 Curt. 223.

Two objects, says Judge Curtis, were intended to be accomplished by the provision in the act of Congress requiring such a protest: 1. To apprise the.collector of the objections entertained by the importer, before it .should foe too late to remove *152 them, if capable of being removed. 2. To hold the importer to the' objections which, he then contemplated, and on which he really, acted, and prevent him, or others in his behalf, from seeking, out defects in the proceedings, after the business should :he •' closed, "by the payment of the money into the treasury: Warren v. Peaselee, 2 Curt. 235 ; Thomson v. Maxwell, 2 Blatchf. 392.

Merchandise entered as silk .ties was imported by the plaintiffs into the port of New York, on which the defendant exacted an ad valorem duty of sixty per cent, upon the assumption-that the articles were properly classified as silk scarfs. 13 Stat. 210.

Prompt objection to that classification was made by the plain-tins ; - and they protested against the payment of the liquidated duty, on thje ground that the goods imported'and entered should be classified as “ articles of weáring-apparel worn by .¿¿ten, women, and children;” and that'they were subject only/to a duty -of thirty-five per. cent ad valorem, as prescribed b^ two prior tariff acts. 12 id. 186, 556.

Properly construed, their protest is .that the articles should only pay duty at thirty-five' per-cent ad valorem, because the" articles imported were wéaring-apparél worn by men, women, and children,-and were mot scarfs,-nor ready-made'clothing in - fact, nor as known in.tradé or commerce.

. Litigation epsued in 'consequence of that difference of' opinion between the importers and 'thé officers of the.government.; ’.but,, when the cáse camelo trial, both!parties agreed that the-merchandise imported should- have been classified as a manufacture ‘of silk not otherwise provided for, under the'concluding clause of sect. 8 in the act of-the 30th of June,-1864, and that it was dutiable at fifty per cent ad valorem, differing from the theory of each party as assumed at the time of the appraisement' and liquidation ‘of the duties.5 13 id. 210. Still^thé plaintiffs claim ed-to recover the difference oflen per cent between the .proper duty "and .-the duty exacted by the defendant1 as collector; and the court below held that they could not do so under their protestas they..could only be héard .to allege'the objections distinctly and' specifically, stated- in their protest, pursuant to ibhe requirement-contained in the act of Congress.'. Judgment! was given for- the defendant;/ and the plaintiffs sued- out thq^ present writ of error, to.correct the-ruling of- tlie Circuit Court.

*153 Three points were ruled by the Circuit Court: 1. That, unless the protest set forth distinctly and specifically the ground of the objection to the amount claimed; it fails to meet the requirement of the.act of Congress. 2. That the office of the protest is to point out to the officers of the customs the precise errors of fact or of law which render the exaction of the duty unauthorized. 3. That the plaintiffs are precluded from insisting that their importation was a manufacture of silk not otherwise provided for, and subject to a duty of fifty per cent instead of sixty, when, by their protest, they allege it to be wearing-apparel, &c., subject to a. duty of thirty-five per cent.

Satisfactory reasons in support of these conclusions are given by the circuit judge, to which it will be sufficient to refer, without repetition. Davies v. Arthur, 13 Blatchf. 34; Norcross v. Greeley, 1 Curt. 120.

Apply these principles to the case before the court, and it is' clear that there is no error in the record.

Judgment affirmed.
