delivered the opinion of the Court;
In 1935, Edith M. Peck causea the title of a savings bank .account, standing in her name to be transferred on the records of the bank to “Edith M. Peck, in trust for Ethel Adelaide Field.” Miss Peck retained exclusive control over the account, with sole right of. withdrawal arid right of revocation, and gave, no further notice of the existence of a trust. ' .
This, suit was brought by Ethel Adelaide Field against the bank' arid the executors of Miss Peck 'to .obtain a decree that the credit balance of the account belonged to the complainant. The executors deriied the validity, of the trust and claimed title. The District Court found in favor of the executors upon the ground that under the law of New Jersey there was no trust, and no yalid gift. The Circuit Court of Appeals reversed the judg-irient, holding that under a state statute the complainant— was, entitled to recover. In so ruling, the court declined
*175
to follow contrary decisions of the Chancery Court of New Jersey.
In 1932, the legislature of New Jersey passed four statutes, in similar terms and approved on the same date, dealing with trust deposits in banks. The text of one of thése provisions is- set forth in the margin.

Prior to these statutes, it had been the law of New Jersey that a mere savings bank deposit made by a decedent in his own name as trustee for another, over which the decedent exercised complete control during his life, was insufficient to establish a gift
inter vivos
or to' create a trust as against the decedent’s legal representatives.

v.
Parker,
69 N. J. Eq. 743, affirmed, 71 N. J. Eq. 777;
The statutes of 1932 came before the Chancery Court of New Jersey in 1936, in two cases decided independently by two Vice-Chancellors,
Thatcher
v.
Trenton Trust Co.,
*176
119 N. J. Eq. 408;
*177 The Circuit Court of Appeals found it impossible to distinguish the facts in the two Chancery cases from those shown here. The court recognized its duty to follow .the law of the State and said that where that law had been determined by the State court of last resort its decision must, be followed irrespective of the federal court’s opinion of what the law ought to be. But the majority of the Circuit Court of Appeals took the . view that it was not so bound “by the pronouncements of. other state courts” but might conclude that “the decision does not truly express the state law.” The court held that the statute of 1932 was “clearly constitutional and unambiguous” and that “contrary decisions” of the Chancery Court of New Jersey were not binding. Accordingly, the judgment of the District Court was reversed.
We think that this ruling was erroneous. The highest state court is the final authority on state law
(Beals
v.
Hale,
Here, the question was as to the construction and effect of a state statute. The federal court was not at liberty to undertake the determination of that question on its own reasoning independent of the construction and effect which the State itself accorded to its statute. That construction and effect are shown by the judicial action through’ which the State interprets and applies its legislation. That judicial action in this instance has been taken by the Chancery Court of New Jersey and we have no other evidence of the state law in this relation. Equity decrees in New Jersey are entered by the Chancellor, who constitutes the Court of Chancery,
4
upon the advice of the Vice-Chancellors,
5
and these decrees, like the judgments of the Supreme Court of New Jersey, are subject to review only by the Court of Errors and Appeals.
6
We have held that the decision of the Supreme Court upon the construction of a state statute should be followed in the absence of an expression of a countervailing view by the State’s highest court
(Erie Railroad Co.
v.
*179
Hilt,
While, of course, the decisions of the Court of Chancery are not binding on the Court of Errors and Appeals, a uniform ruling either by the Court of Chancery or by the Supreme Court oyer a course of years will not be set aside by the highest court “except for cogent and important reasons.”
Ramsey
v.
Hutchinson,
117. N. J. L. 222, 223;
The question has practical aspects of great importance in the. proper administration of justice in the federal *180 courts. It is inadmissible that there should be one rule of state law for litigants in the state courts and another rule for litigants who bring* the same question before the federal courts owing to the circumstance of diversity of citizenship. In the ábsence of any contrary showing, the rule of the Thatcher and Travers cases appears to be the one which would be applied in litigation in the state court, and whether believed to be sound or unsound, it should have been followed by the Circuit Court of Appeals.
The decree of the Circuit Court of Appeals is reversed and that of the District Court is affirmed.
Reversed.
