Plaintiff John Purdy appeals from a judgment of the United States District Court for the District of Vermont in his malpractice action against his former attorneys, defendants Jacob D. Zeldes and the law firm of Zeldes, Needle & Cooper, for their alleged negligent representation of Purdy in a criminal case. The district court (Sessions, J.) granted summary judg-ment to defendants, holding that Purdy’s malpractice claims were barred by the collateral estoppel effect of an earlier habeas proceeding brought by Purdy. In that habeas proceeding, Purdy’s claim that defendants had provided ineffective assistance of counsel in the criminal case was rejected both by the district court and the Second Circuit.
United States v. Purdy,
I. Background
A. Conviction
In May 1996, Purdy was convicted of conspiracy to pay kickbacks in violation of the Anti-Kickback Act, 41 U.S.C. § 51-58. As President and CEO of Purdy Corporation, a company that manufactures parts and components for military aircraft, Pur-dy fell into the practice, apparently widespread in the industry at the time, of paying bribes to purchasing agents in order to secure contracts. Upon learning of a government investigation into these practices, Purdy hired defendants Zeldes and his law firm to represent him. Purdy was eventually indicted and brought to trial in the United States District Court for the District of Connecticut. However, he steadfastly maintained his innocence of the charges both to prosecutors and his attorneys. Although there were discussions between Zeldes and prosecutor Mark Califano about a possible plea, Purdy made the decision to proceed to trial. After a jury found Purdy guilty, the court sentenced him to 37 months in prison in December 1996. 1 His sentence also included a fine of $250,000 and 400 hours of community service.
B. Habeas Proceeding
After his conviction and an unsuccessful appeal to this court,
United States v. Purdy,
Based on this information, in March 1999 Purdy filed a petition for a writ of habeas corpus, 28 U.S.C. § 2255, in the District Court of Connecticut alleging ineffective assistance of counsel. Purdy argued that Zeldes’s representation was constitutionally deficient because Zeldes failed to fully and. adequately inform him about plea discussions with prosecutor Califano, and Zeldes did not provide Purdy with adequate advice about his plea options. Purdy also argued that had Zeldes fully informed him of the prosecutor’s opinion and the results of the cases against the 29 other defendants, he would have pled guilty and his sentence would have been much less than the 37 months he received after trial. During the Connecticut habeas proceeding before Chief Judge Covello, Zeldes admitted that Califano made the above remarks to him and that he did not inform Purdy of the prosecutor’s opinion. 2 However, Zeldes defended his decision not to inform Purdy of the prosecutor’s statement on the grounds that there was no certainty that the case would be assigned to either Judge Burns or Judge Dorsey; that Zeldes had recently represented a client who was sentenced to 4& years in prison by Judge Dorsey in a white collar case; and that he did not want to coerce a client who continued to maintain his innocence into making a guilty plea.
The habeas court analyzed Purdy’s claims under the two-prong test articulated in
Strickland v. Washington,
On appeal, this court considered at length
Strickland’s
first prong — whether Zeldes’s representation was deficient. We held that the habeas court was correct in concluding that, “[bjecause Zeldes did not place an absolute floor under the sentence of 18 months but suggested the ‘possibility, but not a certainty’ of a lower term, ... Zeldes’s communications adequately conveyed the government’s position.”
C. Malpractice Action
After losing his appeal from denial of habeas rehef, Purdy brought this malpractice action against Zeldes and his firm in the District Court of Vermont.

In his complaint, Purdy alleged essentially the same deficiencies in defendants’ representation of him in the criminal case.

Purdy argued that Zeldes was negligent (1) by failing to discover and disclose that 29 other persons charged with the same offense as Purdy avoided any prison sentence by pleading guilty; (2) by failing to disclose Califano’s statements; and (3) by failing to advise Purdy post-sentencing that he could stih cooperate and receive a reduction in his sentence. Defendants moved for summary judgment, arguing that Purdy had a full and fair opportunity to litigate the first two issues before the habeas court and was therefore collaterally estopped from bringing them again in a malpractice action. As to the third claim, Zeldes argued that Purdy did not suffer any harm because he eventually did receive a reduced sentence for cooperating with the government. Judge Sessions agreed on the issue of collateral estoppel, holding:
Purdy v. Zeldes,
[I]n the circumstances of this case, where both the district court and the Second Circuit found that Purdy had failed to establish prejudice under Strickland, Purdy is now collaterally es-topped from re-litigating the issues presented in his habeas petition in this action.
However, the judge held that defendants were not entitled to summary judgment on Purdy’s post-sentence claim of negligence. Id. This appeal followed.
II. Discussion
A. Jurisdiction
Prior to reviewing the Vermont district court’s decision on collateral estoppel, we must consider whether we have jurisdiction over this appeal. The court granted summary judgment to defendants only on plaintiff Purdy’s two claims arising from Zeldes’s pre-sentencing representation. The court denied summary judgment without prejudice “with respect to Purdy’s allegation that Zeldes failed to accurately inform or represent him regarding his post-sentence cooperation opportunities.”
In
Chappelle v. Beacon Communications Corp.,
*258 A plaintiffs attempt to appeal a prior adverse determination following the dismissal of his remaining claims without prejudice necessarily implicates the policies of the final judgment rule. Allowing such an appeal following a voluntary dismissal with prejudice ... furthers the goal of judicial economy by permitting a plaintiff to forgo litigation on the dismissed claims while accepting the risk that if the appeal is unsuccessful, the litigation will end. By contrast, because a dismissal without prejudice does not preclude another action on the same claims, a plaintiff who is permitted to appeal following a voluntary dismissal without prejudice will effectively have secured an otherwise unavailable interlocutory appeal.
Id. at 654. Thus, when a plaintiff is completely free to relitigate voluntarily dismissed claims, the final judgment rule ordinarily precludes this court from reviewing any adverse determination by the district court in that case. However, where, as here, a plaintiffs ability to reassert a claim is made conditional on obtaining a reversal from this court, the finality rule is not implicated in the same way. Unlike the plaintiff in Chappelle, Purdy runs the risk that if his appeal is unsuccessful, his malpractice case comes to an end. We therefore hold that a conditional waiver such as Purdy’s creates a final judgment reviewable by this court.
B. Collateral Estoppel
We review
de novo
the district court’s grant of summary judgment on the basis of collateral estoppel. See
Boguslavsky v. Kaplan,
There is considerable overlap between the issues previously litigated and resolved in Purdy’s habeas petition and those he attempts to raise as malpractice claims. In order to prevail on his legal malpractice claims under Vermont law, which the parties agree provides the substantive law in this diversity case, Purdy must show that his attorney was negligent and that the negligence proximately caused him harm.
Powers v. Hayes,
Nevertheless, Purdy argues that his present claims should not be barred as a matter of law because he faced a higher burden in proving constitutional ineffective assistance of counsel in his habeas action than he will in proving his attorney’s negli
*259
gence in a malpractice action under Vermont tort law. Indeed, this court has recognized that a litigant’s failure to meet a higher burden of proof on an issue in a prior proceeding does not bar him from raising the same issue in a subsequent proceeding in which his burden will be lighter.
Torrington Extend-A-Care Employee Ass’n v. NLRB,
Specifically, Purdy argues that in determining that he could not show prejudice, the habeas court strictly applied the “objective evidence rule.” According to Pur-dy, in the context of a defendant’s claim that he would have accepted a plea offer had his lawyer adequately explained its actual terms, the objective evidence rule requires a defendant to produce some evidence beyond his own testimony in order to show prejudice under
Strickland.
Purdy points out that the habeas court cited
United States v. Gordon,
The district court rejected Purdy’s arguments. The court noted that
Gordon
itself did not necessarily adopt the strict objective evidence test Purdy defends. It also held that even if the “objective evidence rule” were applicable, the habeas court’s decision did not rest on that basis. Although the habeas court cited
Gordon,
that court also went on to make an unfavorable credibility finding with regard to Purdy’s testimony. The district court in this case thus held that “even absent any application of an ‘objective evidence’ rule, it seems clear that the habeas court would have rejected Purdy’s contention that he was prejudiced by Zeldes’ alleged errors.”
The district court’s reasoning is sound. We agree with Purdy that some courts appear to have cited
Gordon
for a strict objective evidence rule, see, e.g.,
Khan v. United States,
In addition, even Purdy’s reading of the objective evidence rule could not save his malpractice claims on this appeal. The habeas court necessarily considered two pieces of objective evidence Purdy used to support his testimony that he would have accepted a guilty plea but for Zeldes’s alleged deficient representation. First, Purdy offered evidence of the vast difference between his actual sentencing exposure following trial (imprisonment for 37 months) and the likely sentencing exposure he would have faced if he had pled guilty (no imprisonment). Under our decision in
Mask v. McGinnis,
“[t]his disparity ... satisfies the prejudice requirement that we articulated in
Gordon.”
Once Purdy produced this objective evidence,
Gordon’s
supposed higher standard of proof did not apply and the habeas court was required to determine whether on the record as a whole Purdy had established “a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Strickland,
A remand of Purdy’s malpractice claims to the Vermont district court would require a second determination of whether Purdy suffered harm from Zeldes’s alleged deficient representation. The doctrine of collateral estoppel is meant to foreclose this type of duplicative litigation. We therefore hold that on this record Purdy is barred by the decision of the habeas court from bringing his current malpractice action.
. For the foregoing reasons, we affirm the district court’s grant of summary judgment to defendants.
Notes
. Purdy's sentence was later reduced to 18 months due to his cooperation with the gov-enunent more than one year after his sentence.
. There is no factual dispute about the content of the conversations between Zeldes and the prosecutor, nor is there any dispute about what information was actually conveyed by Zeldes to Purdy.
. Purdy, a Vermont domiciliary, brought the action in the Vermont district court on the basis of diversity jurisdiction.
. Purdy's initial malpractice complaint raised claims for attorney malpractice, breach of fiduciary duty, and misrepresentation. However, the Vermont district court treated all the .claims as a malpractice action and the parties do the same in their briefs before this court. We therefore analyze all of Purdy’s claims as a claim for legal malpractice.
. It is well established that federal law on collateral estoppel applies to determine the preclusive effect of a prior federal judgment. See
Marvel Characters, Inc. v. Simon,
.
In this Circuit, each of two alternative, independent grounds for a prior holding is given effect for collateral estoppel purposes.
Gelb,
. We note that neither the
Lindstadt
court nor the Supreme Court in
Strickland
had before it the issue of whether the burdens of proof in a habeas proceeding are higher than the burdens in a civil malpractice action. Although it is clear on this record that Purdy is collaterally estopped from bringing his malpractice claim, we need not decide whether malpractice claims are always precluded by prior habeas adjudications of ineffective assistance of counsel. Collateral estoppel in this context is a fact intensive inquiry that is best determined on a case-by-case basis. As the district court stated, “the collateral estoppel effect of the prior proceeding may depend on the specific approach taken by the courts addressing the petition in a particular case.”
