12 monash nmronrnrz. contested question of law arising under the constitution or laws of the United States in the case. The only question in the case seems to be this: Conceding that both parties had grants of tracts of land, ·that each grant was confirmed, that a patent issued for each rancho as confirmed`, and that the tract in controversy in this case is cov- ered by grants and patents, which party acquired the title to the tract in controversy? And that depends upon which in fact acquired the oldest effective grant. That question is to be determined by an ex- amination of the proceedings of the Spanish and Mexican govern- ments in making the inchoate grants to the respective parties, and upon the subsequent acts of the parties and Mexican government under the grants, and before the cession of California to the United States; or upon the facts and laws of Mexico in force in California before its acquisition by the United States. It should afnrmatively appear that there will arise some contested point of law depending upon the constitution or laws of the United States, and what the question is. Nothing of the kind affirmatively appears in the petition or records. It appears to me that this case falls within the rule adopted in Tmjiton v. Nougnes, 4 Sawy. 178, substantially affirmed by the United States supreme court in Gold Washing Oo. v. Keyes, .96 U. S. 199, and within the case of Rcmic v. Casanova, 91 U. S. 379; also McStay v. Friedman, 92 U. S. 723, 724, and San Francisco v. Scott, 111 U. S. 768; S. C. 4 Sup. Ct. Rep. 688. The cases cited by defendants do not appear to me to conflict with the doctrine of those cases. In Hills v. Hornton, 4 Sawy. 198, the whole cseturned upon a disputed construction of the two patents. There was clearly a contested question of law arising under the con- stitution and laws of the United States. The other cases do not ap- A pear to determine or discuss any question arising in this case. It is not enough that a question may possibly arise under the constitution and laws of the United States. It should be made to appear from the facts stated that such a question will arise, and what the question - is, and how it will arise. Should one arise in the course of the trial in the state court material to the correct decision of the case, the rul- ing of the state court may still be reviewed by the United States su- preme court on writ of error in favor of the party against whom the ruling is made. Upon the views expressed, the case must be remanded to the state l court; and it is so ordered.
