*79 Opinion
Paul Anton Zevnik, Michel Y. Horton, Morgan Lewis and Bockius LLP (MLB), and Zevnik Horton LLP (collectively Petitioners) are defendants in a legal malpractice action brought by their former clients Rayonier Inc. (Rayonier), and Southern Wood Piedmont Company (Southern Wood). The alleged malpractice arises from Petitioners’ concurrent representation of Rayonier, Southern Wood, ITT Industries, Inc. (ITT), and ITT Fluid Technology Corporation (ITT Fluid) as coplaintiffs in an insurance coverage action. Rayonier and Southern Wood moved to disqualify Petitioners as counsel for ITT and ITT Fluid in the insurance coverage action based on alleged conflicts of interest and violations of professional responsibilities. The trial court denied the motion based on both the merits and on laches. We affirmed the denial based on laches, and did not reach the merits. Petitioners then moved in this malpractice action to determine the collateral estoppel effect of our opinion in the insurance coverage action, arguing that facts determined by the trial court in the insurance coverage action with respect to the merits of the disqualification motion are conclusively established for purposes of this malpractice action. The trial court denied the motion. Petitioners filed a petition for writ of mandate or prohibition in this court, challenging the denial.
We conclude that the governing rule of law is that if a trial court relies on alternative grounds to support its decision and an appellate court affirms the decision based on fewer than all of those grounds, only the grounds relied on by the appellate court can establish collateral estoppel. In so holding, we agree with the rule of law stated in
Newport Beach Country Club, Inc. v. Founding Members of Newport Beach Country Club
(2006)
FACTUAL AND PROCEDURAL BACKGROUND
Rayonier, Southern Wood, ITT, and ITT Fluid are coplaintiffs in an insurance coverage action that was commenced in September 1991. Petitioners represented the plaintiffs jointly pursuant to the terms of a written agreement. Disputes arose between Rayonier and Southern Wood on one side and ITT and ITT Fluid on the other concerning the division of settlement proceeds. They participated in an arbitration of those disputes in the State of *80 New York, resulting in an award issued in May 2005. A federal court in New York confirmed the arbitration award.
Rayonier and Southern Wood filed a complaint against Petitioners in the United States District Court for the Central District of California in August 2005, alleging professional negligence and breaches of fiduciary duty arising from Petitioners’ representation of the plaintiffs in the insurance coverage action. Rayonier and Southern Wood alleged that Petitioners had favored the interests of ITT and ITT Fluid over the interests of Rayonier and Southern Wood, and that Petitioners had violated State Bar Rules of Professional Conduct. Petitioners promptly moved to be relieved as counsel for Rayonier and Southern Wood in the insurance coverage action. Rayonier and Southern Wood then moved to disqualify Petitioners as counsel for ITT and ITT Fluid in the insurance coverage action.
Rayonier and Southern Wood voluntarily dismissed the federal action and filed their complaint in the present action in September 2005, alleging counts for breach of fiduciary duty, unjust enrichment, breach of contract, and negligence. The counts all arise from Petitioners’ concurrent representation of Rayonier and Southern Wood together with ITT and ITT Fluid as coplaintiffs in the insurance coverage litigation.
The trial court in the insurance coverage action granted Petitioners’ motion to be relieved as counsel for Rayonier and Southern Wood and denied the motion by Rayonier and Southern Wood to disqualify Petitioners as counsel for ITT and ITT Fluid. The court in a written order evaluated the merits of the disqualification motion and concluded that Rayonier and Southern Wood had failed to establish a basis for disqualification. The court also concluded that Rayonier and Southern Wood had delayed unreasonably in bringing the motion and that the motion therefore was barred by laches.
We affirmed the denial of the motion to disqualify based on laches alone and expressly declined to reach the parties’ contentions concerning other grounds asserted by the trial court in support of its ruling. (ITT Industries, Inc. v. Pacific Employers Ins. Co. (Jan. 29, 2007, B187238) [nonpub. opn.].) We concluded that substantial evidence supported the factual findings made by the trial court in connection with its finding of laches. (Ibid.) We also stated, “That Rayonier and Southern Wood only first learned in 2004 of a specific purported breach of the duty of loyalty by counsel may be relevant for purposes of their malpractice action against the attorneys, but that fact is not relevant to nor does it excuse their delay in moving to disqualify counsel.” (Ibid.)
*81 Petitioners filed a motion for determination of collateral estoppel effect of court of appeal’s decision affirming denial of Rayonier’s motion to disqualify defendants in this action in March 2007. They argued that facts determined by the trial court in the order denying the motion to disqualify counsel in the insurance coverage action were conclusively established, and that those facts precluded any finding that they had breached a duty owed to Rayonier and Southern Wood and defeated each of the counts alleged in this action. They also argued that by quoting part of the order denying the motion to disqualify in our opinion, we impliedly endorsed and affirmed the factual findings contained therein. 1
The trial court stated at the hearing on the motion that, as a matter of law, only the finding on which we based our decision—laches—could have collateral estoppel effect. The court also suggested that the disqualification motion and the present action did not involve the same issue because disqualification ultimately turns on considerations different from those that determine whether the lawyer failed to comply with the standard of care. The court denied the motion orally at the hearing and entertained Petitioners’ suggestion to identify issues for proposed interlocutory review (Code Civ. Proc., § 166.1). On June 15, 2007, the court filed an order prepared by Petitioners denying the motion. The order identifies two issues for proposed interlocutory review, including (1) whether issues decided on a motion to disqualify counsel can be collateral estoppel in a malpractice action; and (2) whether collateral estoppel applies to each alternative ground supporting a trial court decision in these circumstances, or only to the ground on which the appellate court based its affirmance. 2
Petitioners filed a petition for writ of mandate or prohibition in this court and requested an immediate stay of discovery. We stayed discovery and issued an order to show cause.
CONTENTIONS
Petitioners contend if an appellate court affirms a trial court decision based on one of two alternative grounds relied on by the trial court, all of the issues decided by the trial court in connection with either ground of decision are *82 conclusively established and binding as collateral estoppel. Petitioners also challenge the trial court’s ruling on other grounds that we need not address.
DISCUSSION
“Res judicata, or claim preclusion, prevents relitigation of the same cause of action in a second suit between the same parties or parties in privity with them. Collateral estoppel, or issue preclusion, ‘precludes relitigation of issues argued and decided in prior proceedings.’ [Citation.]”
(Mycogen Corp.
v.
Monsanto Co.
(2002)
Collateral estoppel precludes the relitigation of an issue only if (1) the issue is identical to an issue decided in a prior proceeding; (2) the issue was actually litigated; (3) the issue was necessarily decided; (4) the decision in the prior proceeding is final and on the merits; and (5) the party against whom collateral estoppel is asserted was a party to the prior proceeding or in privity with a party to the prior proceeding.
(Lucido v. Superior Court
(1990)
Thus, res judicata and collateral estoppel require three common elements: “ ‘(1) A claim or issue raised in the present action is identical to a
*83
claim or issue litigated in a prior proceeding; (2) the prior proceeding resulted in a final judgment on the merits; and (3) the party against whom the doctrine is being asserted was a party or in privity with a party to the prior proceeding. [Citations.]’ [Citation.]”
(People v. Barragan
(2004)
Difficult questions concerning whether an issue was “necessarily decided” arise when considering the preclusive effect of a trial court judgment that is based on alternative grounds, each of which was sufficient to support the judgment. The first Restatement of Judgments expressed the view that each alternative ground in those circumstances establishes collateral estoppel. (Rest., Judgments, § 68, com. n, pp. 307-308.) California opinions of that era followed the Restatement rule.
(Evans v. Horton
(1953)
The issue presented here is the preclusive effect of a trial court decision based on alternative grounds, each of which was sufficient to support the decision, after an appellate court has affirmed the decision on only one of the
*84
alternative grounds without deciding the other grounds. The first Restatement of Judgments and the Restatement Second of Judgments both express the view that only the ground relied on by the appellate court is collateral estoppel in these circumstances. (Rest., Judgments, § 69, com. b, p. 316; Rest.2d Judgments, § 27, com. o, p. 263.) Recent California opinions have adopted this rule.

Butcher, supra,
*85
The opportunity for review of a decision is an important procedural protection against a potentially erroneous determination and is a factor to consider in determining whether collateral estoppel applies.
(Vandenberg
v.
Superior Court
(1999)
Moreover, to accord collateral estoppel effect to alternative grounds relied on by the trial court after the appellate court affirmed on another ground and declined to review the alternative grounds would put pressure on appellate courts to review alternative grounds as a matter of course, in order to avoid the unintended consequence of establishing collateral estoppel on grounds that the appellate court did not review. This would dramatically increase the burden on appellate courts. Any benefit that might result from precluding the relitigation of issues in potential collateral litigation, which may or may not arise, would come at the cost of increasing the burden on the appellate court in the initial action. If an appellate court is aware of or anticipates collateral litigation and believes that to establish collateral estoppel on an alternative ground would be beneficial, the court may affirm the trial court judgment on more than one ground. (See Rest.2d Judgments, § 27, com. o, p. 263.) 5 The respondent on appeal may urge the court to do so. In our view, a blanket rule according collateral estoppel effect to each alternative and unreviewed ground for a trial court decision in these circumstances for the purpose of precluding relitigation of issues in collateral litigation is unnecessary and would be unwise.
*86
We decline to follow the authorities suggesting that each of the alternative grounds relied on by the trial court is collateral estoppel after an appellate court affirmed the decision on only one ground and declined to decide the others.

Notes
Our prior opinion in the insurance coverage action plainly refutes the argument that we affirmed any factual findings other than those supporting the trial court’s finding of laches. Accordingly, we need not discuss the argument further.
In light of our conclusion that only the ground relied on by the appellate court in these circumstances can establish collateral estoppel, we need not address the first issue identified by the trial court and express no opinion on that issue.
Mycogen
stated: “While the term ‘res judicata’ has been used to encompass both claim preclusion and issue preclusion, we here use the term ‘res judicata’ only to refer to claim preclusion. As we have noted, ‘The doctrine of collateral estoppel is one aspect of the concept of res judicata. In modem usage, however, the two terms have distinct meanings.’ [Citation.]”
(Mycogen Corp. v. Monsanto Co., supra,
The primary reasons commonly stated for denying collateral estoppel effect to any of the alternative and sufficient grounds for a trial court decision are (1) an alternative and sufficient ground for a decision might not receive the same degree of attention and scrutiny from the trial court as a sole ground for a decision; (2) alternative and sufficient grounds make reversal on appeal less likely and discourage appeals, so the opportunity to appeal does not provide sufficient assurance of the reliability of any of the alternative grounds; and (3) a contrary rule would encourage the filing of appeals solely in an effort to avoid the collateral estoppel effect of determinations on issues that may or may not arise in collateral litigation. (See
Halpern
v.
Schwartz
(2d Cir. 1970)
“If the judgment of the court of first instance was based on a determination of two issues, either of which standing independently would be sufficient to support the result, and the appellate court upholds both of these determinations as sufficient, and accordingly affirms the judgment, the judgment is conclusive as to both determinations.” (Rest.2d Judgments, § 27, com. o, p. 263.)

Skidmore, supra,
We question whether this formalistic view is consistent with the fundamental rule that an appellate court will affirm a judgment if it is correct on any ground, regardless of the trial court’s stated reasons, and that an appellate court reviews the trial court’s decision rather than the reasons for the decision.
