?o9 U. 8. Olinion of the Court., cision of the Circuit Court of Appeah in the case of Arbue2/? v. Blackburn, ?upra, a Federal court of equity has ao jurisdiction of the subject-matter of the bill of complaint, viz., that it has no jurisdiction to re?rain the dairy and food commissioner of a State from issuing bulletins or circulars claiming that an arti- cle of food is in violation of the criminal laws of a State." And it is urged that such was the reason given by the court i?. its opinion and order dismissing the bill, and that as the de- rision of the court was right it should not be reversed, because the reason given for it in the certificate was not the correct reason.

The bill was dismissed for want of jurisdiction and the- case was appealed to this court. One of the grounds for the dismissal was, as certified, "that ther? was no jurisdiction in this matter because the bill was a suit against the State of Mississippi and in .?iolatien of the Eleventh Amendment to the Constitution o( the United States."
