delivered the opinion of the Court.
In 1928, the Brinkerhoff-Faris Trust & Savings Company, ■acting as trustee for its shareholders, brought this suit in a Missouri court against the Treasurer of Henry County, Missouri, to enjoin him from collecting or attempting to collect a certain part of the taxes assessed against them for the year 1927 on the shares of its stock; and, pending decision in this suit, to restrain the prosecution of an action already brought by him against the plaintiff for that purpose.
The bill alleged that the township assessor had intentionally and systematically discriminated against the shareholders by assessing bank stock at full value, while intentionally and systematically omitting to assess certain classes of property and assessing all other classes of property at 75 per cent or less of their value. It asserted that, to the extent of 25 per cent, the assessments were void because such discrimination violated the equal protection clause of the Fourteenth Amendment. And it recited that the plaintiff had tendered, and w.as continuing to tender, payment of the 75 per cent of the taxes assessed, which amount it conceded was due. As grounds for equity jurisdiction, the bill charged that relief could not be had at law, either by way of defense in the pending action brought by the Treasurer or by paying'the tax in full under protest and suing for a refund of 25 per cent thereof; and that no administrative remedy for the relief
The defendant’s answer denied all the allegations of discrimination and further opposed relief in equity on the grounds that the plaintiff had not pursued remedies before the County or State Board of Equalization pursuant to Articles 3 and 5 of Chapter 119 of the Missouri Revised Statutes of 1919; and that the plaintiff was guilty of laches in not so doing. The trial court refused the injunction and dismissed the bill, without opinion or findings of fact.
The Supreme Court of Missouri held, on appeal, that relief from the alleged discriminatory assessment could not be had in any suit at law; that this bill in equity was the appropriate and only remedy, unless relief could have been had by timely application to some administrative board; and that neither of the boards of equalization was charged with the power and duty to grant such relief. But, without passing definitely upon the question of discrimination, it concluded that if the plaintiff had “ at any time before the tax books were delivered to the collector, filed complaint before the State Tax Commission, that body, in the proper exercise of its jurisdiction, would have granted a hearing, and would have heard evidence with respect to the valuations complained of, and, if the charges contained in the complaint had been found to be true, the valuations placed on its property would have been lowered, or that on other property raised, the property omitted from the assessment roll would have been placed thereon, and the discrimination complained of thereby removed. The remedy provided by the statute is adequate, certain, and complete.” Compare

The plaintiff seasonably filed a petition for a rehearing in which it recited the above facts and asserted, in addition to its claims on the merits, that, in applying the new construction of Article 4 of Chapter 119 to the case at bar, and in refusing relief because of the newly found powers of the Commission, the court transgressed the due
First.
It is plain that the practical effect of the judgment of the Missouri court is to deprive the plaintiff of property without affording it at any time an opportunity to be heard in its defense. The plaintiff asserted an invasion of its substantive right under the Federal Constitution to equality of treatment.
Greene
v.
Louisville & Interurban R. R. Co.,
Under the settled law of the State, that remedy was the only one available. That a bill in equity is appropriate and that the court has power to grant relief, even under the new construction of the statute dealing with the Tax Commission; is not questioned.

And it is held by the state court in this case that no other judicial remedy is open to the plaintiff and that no administrative
If the judgment is permitted to stand, deprivation of plaintiff’s property is accomplished without its ever having had an opportunity to defend against the exaction. The state court refused to hear the plaintiff’s complaint and denied it relief, not because of lack of power or because of any demerit in the complaint, but because, assuming-power and merit, the plaintiff did not first seek an administrative remedy which, in fact, was never available and which is not now open to it. Thus, by denying to it the only remedy ever available for the enforcement of its right to prevent the seizure of its property, the judgment deprives the plaintiff of its property.
Second.
If the result above stated were attained by an exercise of the State’s legislative power, the transgression of the due process clause of the Fourteenth Amendment
It is true that the courts of a State have the supreme power to interpret and declare the written and unwritten laws of the State; that this Court’s power to review decisions of state courts is limited to their decisions on federal questions; 6 and that the mere fact that a state court has rendered an erroneous decision on a question of state law, or has overruled principles or doctrines established by previous decisions on which a party relied, does not give rise to a claim under the Fourteenth Amendment or otherwise confer appellate jurisdiction on this Court. 7
Third. The court’s finding of laches was predicated entirely on the plaintiff’s failure to apply to the State Tax Commission. In view of what we have said, this ground is not sufficient independently to support the judgment. And, as the Supreme Court of Missouri did not decide whether the allegations of the plaintiff’s bill were sustained by the proof, we do not inquire into the merits of the plaintiff’s claim under the equal protection clause. The judgment is reversed and the case remanded for further proceedings not inconsistent with this opinion.
Reversed.

v.
Schlotzhauer,
The reason which prompted the Supreme Court to reexamine and overrule the
Ladede
case is thus stated in its opinion: “It is doubtful whether the evidence in this case warrants a finding that the local assessor intentionally and systematically undervalued real estate and personal property listed with him, other than bank stock; but there can be no question but that his failure to assess sucking animals and poultry was both intentional and pursuant to system. ... If the owners of bank stock are entitled to an abatement of a portion of their taxes because other property was undervalued, it would appear on principle that all taxpayers of the state should be entirely relieved, so far as the taxes for 1927 are concerned, because the owners of poultry were not taxed at all. It seems necessary that we rechart our course,”
Equitable relief was denied solely on the equitable doctrines that the plaintiff had an adequate legal remedy by application to the Commission and was guilty of laches in not pursuing it.

The process of trial and error, of change of decision in order to conform with changing ideas and conditions, is traditional with courts administering the common law. Since it is for the state courts to interpret and declare the law of the State, it is for them to correct their errors and declare what the law has been as well as what it is. State courts, like this Court, may ordinarily overrule their own decisions without .offending constitutional guaranties, even though parties may have acted to their prejudice on the faith of the earlier decisions.

Had there been no previous construction of the statute by the highest court, the plaintiff would, of course, have had to assume the risk that the ultimate interpretation by the highest court might differ from its own. Likewise, if the administrative remedy were still .available to the plaintiff, there would be no denial of due process in that regard.
