The record shows that the defendants in error sought to enjoin the collection of a judgment against their property to enforce an assessment under the drainage laws of Louisiana, (1) because under the operation of the laws authorizing the judgment nothing more remained to be paid thereon; and (2) because the judgment had, in terms, been released and discharged by certain acts of the general assembly of the state, passed in 1877 and 1878. If the case was decided below on the first of these grounds no federal question is involved.

It was settled long ago that, in cases coming to this court from the supreme court of Louisiana, the opinion of the court below, as set out in the record, may be referred to, if necessary, to determine whether the judgment is one we have authority to review. Armstrong v. Treasurer of Knox Co. 16 Pet. 285; Almonster v. Kenton, 9 How. 9; Grand Gulf R. R. & Bkg. Co. v. Marshall, 12 How. 167; Cousin v. Blanc, 19 How. 207; Murdock v. Memphis, 20 Wall. 633. From the statement of the case and the opinion found in this record, it is manifest the decision was placed entirely on the ground that the judgment was not collectible under the law as it stood before the acts of 1876 and 1877 were passed. Consequently the case was disposed of before the federal question presented by the pleadings was reached, and that question was not and need not have been decided.

Under these circumstances we have no jurisdiction, and the motion to dismiss is granted.
