We are asked to decide in this Erie 1 case whether a change in state decisional law — in this instance, Mississippi’s conversion from the “consumer expectations” to the “risk-utility” test in products liability actions— constituted an extraordinary circumstance that vested the district court with discretion to grant Fed.R.Civ.P. 60(b)(6) relief. Because we hold that it did not, we reverse.
I
The relevant background facts are set out in our prior opinion in this case,
see Batts v. Tow-Motor Forklift Co.,
In 1984 plaintiff-appellee Myron Batts (“Batts”) was injured when a coworker using a forklift collided with Batts.
Batts I,
In 1988 Batts brought a diversity action against defendant Tow-Motor Forklift Company, the manufacturer of the forklift, and its successor-in-interest, defendant-appellant Caterpillar Industrial, Inc. (“Caterpillar”), alleging
inter alia
theories of negligence and strict liability.
Id.
at 1388. The ease was tried in March 1991.
Batts II,
One of Caterpillar’s principal defenses was that the absence of the devices on which Batts relied to establish liability, coupled with the danger of the forklift operator’s not facing the direction of travel, was open and obvious to the forklift owner (Batts’ employer) and to users (the employee operators), thus barring recovery by Batts under Mississippi law.
Id.; see Batts II,
*746
Following denial of his post-verdict motions, Batts appealed to this court and moved the court to stay the appeal pending the Mississippi Supreme Court’s expected decision in
Sperry-New Holland v. Prestage,
In 1991, when the case was tried, and in 1992, when we decided Batts’ appeal, we understood Mississippi to follow the consumer expectations rather than risk-utility test in strict liability actions.
See id.
at 1392;
Melton v. Deere & Co.,
On March 25, 1993 — subsequent to issuance of our mandate on January 4,1993 — the Mississippi Supreme Court filed its opinion in
Prestage,
holding that Mississippi applied the risk-utility test of products liability, and that it had done so since 1988.
Prestage,
On appeal, the Mississippi Supreme Court affirmed, reasoning that it had moved away from consumer expectations analysis in two 1988 decisions,
Hall v. Mississippi Chem. Exp., Inc.,
On April 19,1993 Batts filed in the district court below a Rule 60(b)(6) motion, urging the court on the basis of
Prestage
to relieve him from the adverse judgment.
See Batts II,
The district court thereafter granted Caterpillar leave to take an interlocutory appeal of the order, and stayed all proceedings below. A panel of this court first denied, and later granted, leave to appeal.
Caterpillar asks us to reverse the order of the district court and reinstate the prior judgment in its favor.

A
Rule 60(b)(6) provides that a court may “relieve a party ... from a final judgment ... for ... any other reason justifying relief from the operation of the judgment.” Rule 60(b) sets out five specific bases for granting relief from a final judgment, followed by clause (b)(6). We have held that this clause’s “‘any other reason’ language refers to any other reason than those contained in the five enumerated grounds on which a court may grant a Rule 60(b) motion.”
Government Fin. Servs. One Ltd. Partnership v. Peyton Place, Inc.,
B
The district court granted Batts’ Rule 60(b)(6) motion on the ground that the case had been tried under the consumer expectations test, when Mississippi had in fact converted earlier to the risk-utility test.
See Batts II,
At the time this case was tried, the law of this circuit — reiterated in 1989 in
Mellon
— was that Mississippi followed the eon-sumer expectations test.
Melton
was decided after the 1988 decisions in
Hall
and
Whittley,
which the Mississippi Supreme Court said in
Prestage
changed the state’s products liability law.
Prestage,
The district court vacated the judgment in favor of Caterpillar on the basis of a change in decisional law announced after the 1991 trial and 1992 affirmance. In
Bailey
we stated that “[a] change in decisional law after entry of judgment does not constitute exceptional circumstances and is not alone grounds
*748
for relief from a final judgment.”

Bailey,

We think a proper understanding of the limited circumstances in which post-judgment relief is available when decisional law changes, and of our role as an Erie court attempting to determine and apply state law, supports the conclusion that a change in state decisional law, rendered after this court makes an Eñe prediction, will not normally constitute an extraordinary circumstance, and cannot alone be grounds for relief from a final judgment pursuant to Rule 60(b)(6). 6

“Numerous courts have held that the mere showing of a change in the law is not enough to demonstrate such an extraordinary situation when the judgment has become final.”
Overbee v. Van Waters & Rogers,
Absent some showing of extraordinary circumstances, courts have refused to vacate their prior judgments where they correctly applied federal law, and a subsequent Supreme Court ruling changed the law.
See, e.g., Travelers Indent,. Co. v. Sarkisian,
Changes in decisional law based on constitutional principles are not of themselves extraordinary circumstances sufficient to justify Rule 60(b)(6) relief. For instance, in
Collins v. City of Wichita,
A circuit court’s announcement of a new rule of federal law, like a Supreme Court pronouncement, is similarly insufficient without more to justify Rule 60(b)(6) relief.
See Ashland Oil, Inc. v. Delta Oil Prods. Corp.,
2
Our role as an
Erie
court strengthens, rather than undermines, the proposition that a change in decisional law is insufficient to constitute an extraordinary circumstance. “In diversity cases, we apply substantive state law.”
Rogers v. Corrosion Prods., Inc.,
“In order to determine state law, federal courts look to final decisions of the highest court of the state. When there is no ruling by the state’s highest court, it is the duty of the federal court to determine as best it can, what the highest court of the state would decide.”
Labiche v. Legal Sec. Ins. Co.,
The general rule that a change in decisional law will not ordinarily warrant Rule 60(b)(6) relief has greater force in an
Erie
case because in this context a federal court is doing no more than fulfilling its obligation scrupulously to determine how a state court would decide a question. We find the Second Circuit’s well-reasoned opinion in
DeWeerth v. Baldinger,
Eñe requires that diversity courts follow state law on substantive matters not governed by the Constitution or by federal law. Id. at 1272. The court is not required to be prescient. Instead, “[w]hen confronted with an unsettled issue of state law, a federal court sitting in diversity must make its best effort to predict how the state courts would decide the issue.” Id. at 1273. Eñe and its progeny require no more of a federal court than conscientiously to satisfy its duty to predict how the state court will decide a question. See id. at 1274.
“However, the fact that federal courts must follow state law when deciding a diversity case does not mean that a subsequent change in the law of the state will provide grounds for relief under Rule 60(b)(6).” Id. at 1272-73. Eñe contemplates that on any open question of state law, a federal as opposed to a state court will determine the applicable rules of law. See id. at 1273. That a subsequent state court resolves the question differently does not render the federal diversity court decision invalid, or mar the proceeding as unfair. Id.
The very nature of diversity jurisdiction leaves open the possibility that a state court will subsequently disagree with a federal court’s interpretation of state law. However, this aspect of our dual justice system does not mean that all diversity judgments are subject to revision once a state court later addresses the litigated issues. Such a rule would be tantamount to holding that the doctrine of finality does not apply to diversity judgments, a theory that has no basis in Eñe or its progeny.
Id. at 1273-74.
Consistent with the reasoning and result of
DeWeerth
are cases such as
Dowell v. State Farm Fire and Cas. Auto Ins. Co.,

Batts emphasizes that this case presents an extraordinary circumstance because he requested that this court stay the appeal in Batts I pending the Mississippi Supreme Court’s anticipated ruling in Prestage. We find nothing in the district court’s opinion to indicate that it exercised its discretion on the basis of Batts’ motion for a stay of the appeal. The district court’s opinion does not mention the request. Instead, as we have *751 noted, the court below granted relief on the ground that it had incorrectly instructed the jury concerning the consumer expectations test, which had been replaced by the risk-utility test three years prior to the Batts’ trial. Because we are reviewing the district court’s decision under an abuse of discretion standard, and since this factor apparently played no role in the court’s exercise of its discretion, we hold that Batts’ request for a stay does not change our analysis. 7
Batts did not present an extraordinary circumstance that warranted Rule 60(b)(6) relief. The district court therefore abused its discretion in granting Batts’ motion. The order vacating the final judgment below is therefore
REVERSED.
Notes
.
Erie R.R. Co. v. Tompkins,
. Judge Reavley disagreed with this circuit’s interpretation of Mississippi law.
See Melton,
. This statement is dicta because the panel had already held that Rule 60(b)(6) relief was unavailable to appellant because he had also sought relief on the basis of Rule 60(b)(5).
. In
Picco v. Global Marine Drilling Co.,
. Our decision in
Satcher v. Honda Motor Co.,
. We do not hold that a change in decisional law can
never
be an extraordinary circumstance. Courts may find a special circumstance warranting relief where a change in the law affects a petition for habeas corpus, where notions of finality have no place.
Matarese v. LeFevre,
. Batts also relies on
Pierce,
in which the Tenth Circuit granted relief from summary judgment where the state law precedent upon which the district court relied was subsequently overruled.
Pierce
presented extraordinary circumstances in that separate state and federal actions arose from the same incident and involved the same parties. In
DeWeerth,
