p. 312the plaintiff a sum of money equal to the. taxes, penalties, interest and attorney’s fee, to recover which this action was brought, and costs of suit, which offer and tender have not been accepted; but the money has been deposited by the defendant in bank, in accordance with the provisions of section 1500 of the Civil Code of California, which reads as follows :
‘ An obligation for the payment of money is extinguished by a due offer of payment, if the amount is immediately deposited in the name of the creditor, with some bank of deposit within this State of good repute, and notice thereof is given to the creditor.’ ”
Mr. William H. H. Hart, Attorney General for the State of California, after stating the fact of the offer and deposit of money as aforesaid, said:
' I respectfully submit that this offer should not prevent the hearing of this cause and a decision of the constitutional question involved.There are other cases depending upon the determination of this. It will be seen in the record, that there was a stipulation in this case, and three others, that the decision that might be made in this court in the case of The People of the State of California v. The Central Pacific Railroad Co., should be treated as a decision in all of the cases, provided the decision should be upon points in volved therein, and if not so made, then the judgment of the Circuit Court in any of these cases should be set aside and findings of fact therein made. That case .having been decided against the State ^because the assessment included steamboats and federal franchise,-(see 127 U. S. 1 ,) and the question made in the present case under the Fourteenth Amendment not having been passed upon, counsel of the parties signed a stipulation to have the judgment set aside in this case, and to submit the same to the Circuit Court upon the facts stated in the stipulation, and it was accordingly thus submitted and decided by the Circuit Court, the design of the stipulation thus submitting the case being to obtain a decision which would also dispose of the remaining two cases embraced
p. 313in the stipulation first made, that stipulation having been made to carry out the design of the first, that is, to obtain a decision that will dispose of all thesé cases.Therefore, nothing short of a payment of what is claimed in those two cases, as well as in this, should be regarded as dispensing with a decision of the constitutional question raised in this case, and which is the same in the three cases.It is of the utmost importance to the people of the State of California, that it be determined whether an assessment of the property of railroad corporations in the manner required by the constitution of California is valid, so it may be known, whun these assessments are made, • whether they can be included in the sources of revenue that can be relied upon in the administration of the government of that State, or whether such corporations are at liberty to decline to pay taxes, and to pay only- what sums and when they may choose, merely as voluntary contributions to the public funds of California.The court declined to hear further argument.Mr. George A. Johnson, a former Attorney General of the State of California, and Mr. Samuel Shelldbarger and Mr. Jeremiah M. Wilson also submitted briefs for the plaintiff in error.
Mr. George F. Edrmoncls, Mr. Harvey S. Brown and Mr. Greed Haymond submitted briefs on the merits for the defendant in error.
Mr. Harvey S. Brown also submitted a brief on a morion to dismiss the writ of error.
delivered the opinion of the court.
Upon the fact most properly and frankly admitted in open court by the Attorney General of the State of California, there can be no doubt that this writ of error must be dismissed-, because the cause of action has ceased to exist. Any obligation of the defendant to pay to the State the sums sued for in this case, together with interest, penalties and costs, has been
p. 314extinguished by the offer to pay all these sums, and the deposit of the money in a bank, which by a statute of the State have the same effect as actual payment and receipt of the money. And the State has obtained everything that it could recover in this case by a judgment of this court in its favor. The duty of this court, as of every judicial tribunal, is limited to determining rights of persons or of property, which are actually controverted in the particular case before it. When, in determining such rights, it becomes necessary to give an opinion upon a question of law, that opinion may have weight as a precedent for future decisions. But the court is not empowered to decide moot questions or abstract propositions, or to declare, for the government of future cases, principles or rules of law which cannot affect the result as to the thing in issue in the case before it. No stipulation of parties or counsel, whether in the case before the court .or in any other case, can enlarge the power, or affect the duty, of the court in this regard.
The case at bar cannot be distinguished in principle from previous cases in which writs of error have been dismissed by this court under similar or analogous circumstances. Lord v. Veazie, 8 How. 251 , 255; Cleveland v. Chamberlain, 1 Black, 419 ; Wood Paper Co. v. Heft, 8 Wall. 333 ; San Mateo County v. Southern Pacific Railroad, 116 U. S. 138 ; Little v. Bowers, 134 U. S. 547 ; Singer Manuf. Co. v. Wright, 141 U. S. 696 . See also Elgin v. Marshall, 106 U. S. 578 .
Writ of error dismissed.
