Much testimony was taken, and the District Court found that when complainants offered their tea for entry the standard samples contained no coloring matter whatever,, but did contain a far greater amount of other foreign substances than did complainants’; that the tea refused entry is worth in the open market nearly four times as much per pound as is the standard sample by which its. acceptance or rejection was gauged; that the sole cause for rejecting the tea in question is that it showed coloring matter, to wit, Prussian blue, in proportion ranging from 9 to 19 parts of blue in a million of other and unobjectcd to elements. It is conceded by both sides that Prussian blue cannot be proved to produce any deleterious results; that it is found in the United States Pharmacopeia as a drug sometimes, used for common purposes. A careful study of the testimony results in the conclusion that these findings of fact are entirely accurate.
[1, 2] Manifestly Congress undertook to deal fully with the subject of tea importation. It provided for the creation of this Board of Tea Appeal; also for the adoption of physical standard samples; to the members of the board it confided the authority — and the sole authority — to determine whether samples of tea offered for entry are or are not inferior to the standards in the particulars specified. Congress, however, has specified carefully the particulars in which this inferiority must be found in order to reject the tea. The question to be answered upon every examination is: Are the teas “of inferior purity, quality, and fitness for consumption to such standards”? Although the sentence is conjunctive, we think it may fairly be construed dis-junctively, as providing that tea shall be prohibited which falls below the standard either in purity, in quality, or in fitness for consumption.
It is now contended for the government that although the board may be satisfied that a certain lot of tea is fully equal, indeed superior, to the standard — in purity, in quality, and in fitness for consumption— the board must nevertheless reject it, if they find that it contains coloring or facing matter. It does not seem to us that the statute warrants such rejection, unless the coloring matter plus other impurities makes the tea below standard in purity, or- the coloring matter makes the tea below standard in quality, or the coloring matter makes the tea less fit for consumption than the standard. Within the field of investigation confided to them the Board of Examiners are the sole judges; but they have been given no authority to extend the field of investigation beyond the limits staked out by Congress. If Congress had intended that tea should be rejected because of coloring matter which was not sufficient in quantity, or such in character as to bring it below standard in the three particulars specified, it must be presumed that Congress would have so stated in the act. We do not see that Buttfield v. Stranahan, 192 U. S. 470, 24 Sup. Ct. 349, 48 L. Ed. 525, applies. That case held merely that the board was the final judge in its allotted field; it did not indicate that the board had any power to extend that field.
The record shows that this tea is superior to standard in all three, specified requirements. It also shows that nevertheless it will be re*362jected as soon as the board examines it, because of a fourth unspecified requirement. The members of the board are appointed, by the Secretary, who has the power to remove them; it is not disputed that they will act in conformity to the requirements he has prescribed for their guidance in regulations 22 and 23. Indeed, upon inquiry as to the issues by the District Judg'e, counsel for the government conceded that it was the intention of the officers of the government-“to keep out all the tea that has any coloring matter in it, no matter whether such matter was put into it, so far as the observer can discover, for the purpose of coloring it or not, or whether it is mere carelessness or accident”; also thát teas will be rejected “if the said teas are found to contain matters adapted for use as coloring or- facing of any kind or in any quantity, irrespective of whether the same is or is not used or applied so as to conceal damage or inferiority.”
[3] If the government officers have no authority to reject teas, superior to the standard in all the requirements specified by law, such rejection would be an invasion of the rights of complainants, who, relying oh the statute, have brought to this country teas which the statute advised them they could enter. This is no academic construction of a statute in advance of its application; we are dealing with a concrete case; the teas have been bought and brought here at large expense in reliance upon the statute; they have been once rejected, and unless the injunction be granted they will inevitably be again rejected, with the result that they must be removed from this country or destroyed. There is no ground for the contention that the application is premature, on the theory that non constat what is shown the board may finally admit the teas; the record establishes-the converse of this proposition. Time will be saved and loss reduced by now enjoining a threatened injury, if thé1 action which is threatened is without authority of law. Merritt v. Welsh, 104 U. S. 694, 26 L. Ed. 896; Philadelphia Company v. Stimson, 223 U. S. 605, 32 Sup. Ct. 340, 56 L. Ed. 570; Williams v. Molther, 198 Fed. 460, 117 C. C. A. 220; Vicksburg Waterworks Company v. Vicksburg, 185 U. S. 65, 22 Sup. Ct. 585, 46 L. Ed. 808.
[4] As to the so-called Read test, we do not think it necessary to discuss the question whether such a method of investigation may or may not be properly described as “chemical.” To the board exclusively is left the determination of the question whether offered teas are equal to the standards in purity, quality, or fitness for consumption;'whatever means they -may adopt to satisfy themselves as to the degree of purity, of quality, or of fitness it would seem they may use. But in applying the information obtained by such use to the question, “Shall this tea be admitted or reje.cted?” they must follow the directions only -of the statute and of such regulations as are not inconsistent with the statute. That they intend to follow the directions of regulations 22 and 23 is undisputed. In our opinion these regulations are inconsistent with the statute, because they undertake to direct the board to reject tea which contains any coloring matter, although the board may be convinced as the result of all the tests they apply that the coloring ■matter is present in such harmless quantities that the tea is not inferior *363to the statutory standards in purity, quality, or fitness for consumption.
The decree is reversed, and cause remitted, with instructions to decree in conformity with this opinion.
