When substantial federal questions are presented in the District Court, that court may in its discretion exercise pendent jurisdiction over state claims arising out of the same nucleus of operative fact. Considerations of economy, convenience, and fairness may favor the exercise of jurisdiction; on the other hand, principles of comity and the desirability of “a surer-footed reading of applicable law” 1 support the determination of state claims in state court. If the federal claims in a case are resolved before trial, the District Court retains power to decide the state claims, but may exercise its discretion to dismiss them without prejudice.
In this case, after the federal securities law claims had been settled or dismissed as to all defendants, the District Court retained pendent jurisdiction over common law claims that one defendant, an attorney, had breached his fiduciary duty to the plaintiff, his client. The court held a three-day trial and issued a lengthy decision dealing with novel and difficult issues of local law. No court of the District of Columbia has provided any guidance regarding the standards defining an attorney’s fiduciary duties, the construction of the conflict of interest provisions of the Code of Professional Responsibility, or the remedies for breach. Under these circumstances, we find that the District Court abused its discretion in exercising pendent jurisdiction over the local claims.
I. History of the Litigation
Financial General Bankshares, Inc. (FG) filed this lawsuit in the United States District Court for the District of Columbia after receiving information that a group of Middle Eastern investors had acquired twenty percent of FG’s common shares and intended to obtain control of the company by acquiring additional stock. The complaint, filed February 17,1978, sought relief against unnamed persons and entities believed to be purchasing FG’s shares, and also against named individuals and corporations alleged to be participating in the takeover scheme. 2 One of these defendants, appellant Eugene J. Metzger, is an attorney who had served as counsel to FG and who owned approximately 1.6 percent of FG’s common stock.
The complaint alleged that Metzger and the other defendants had violated several provisions of the federal securities laws 3 *770 and the Virginia Take-Over Bid Disclosure Act. FG sought preliminary and permanent injunctive relief barring the defendants from attempting to influence the management of FG and from acquiring any further shares of FG stock. It also asked the court to order the defendants to divest themselves of the FG stock they had previously purchased. In addition, the complaint asserted a pendent local claim against Metz-ger. Asserting that Metzger had breached his common law fiduciary and ethical obligations to FG and its shareholders, FG sought both compensatory and punitive damages. Joint Appendix (JA) 28-50.
On March 18, 1978 the Securities and Exchange Commission filed an action against the defendants named in the FG complaint, also asserting violations of the federal securities laws. On the same day the SEC’s action was settled by entry of consent judgments and undertakings. The defendants filed disclosure statements pursuant to Section 13(d) of the Securities Exchange Act of 1934, 15 U.S.C. § 78m(d) (1976). They were permitted to make a tender offer for FG’s stock provided they received all requisite banking and regulatory approvals, tendered for 100 percent of the shares at a specified minimum price, and compensated former FG shareholders who had sold shares to the defendants at a lower price.
FG then, on March 21, 1978, amended its complaint to allege that the defendants’ disclosure statements were false and misleading in violation of Section 13(d). JA 72-74. On April 27, 1978, finding that FG had shown a likelihood of prevailing on its Section 13(d) claim, the District Court entered a preliminary injunction. The defendants were ordered not to acquire any further interest in FG common stock until they had offered rescission to the shareholders from whom they had purchased shares during December 1977 and January 1978. At the same time the court dismissed FG’s causes of action against all defendants under other federal securities law provisions and the Virginia takeover statute. JA 1264. 4
Extensive discovery took place during the following two years. See Docket Entries, JA 14-25. On May 16, 1980 the court granted FG leave to file an amended complaint realleging the Section 13(d) claims against the defendants, adding new Section 13(d) defendants, and realleging the common law fiduciary claims against Metzger. JA 256-291. On May 21, 1980 all defendants except Metzger reached a settlement agreement with FG; they were subsequently dismissed voluntarily by a stipulation and order signed on July 25, 1980. JA 358-359. Under the terms of the settlement FG agreed not to oppose the defendants’ takeover attempt; the defendants agreed to offer a premium price for FG’s shares. JA 311-320. 5
Metzger was left as the sole defendant in ■the case. He moved to dismiss the federal securities law claims against him and argued that, if FG’s federal claims against him were dismissed, its pendent local law claims against him for breach of fiduciary duties should also be dismissed. JA 293-302. On August 2, 1980 the District Court entered summary judgment for Metzger on the federal claims on the ground that FG was no longer entitled to any injunctive relief. However, the court retained pendent jurisdiction over the. common law claims. JA 360-362.
After a three-day trial, from November 19 to 21, 1980, the court held in favor of
*771
plaintiff FG. The District Court’s 54-page memorandum opinion was filed on July 31, 1981. JA 1263-1316,
reported at
First, to determine whether Metzger had violated his common law fiduciary duties, the court relied on the standards set forth in the Disciplinary Rules of the American Bar Association Code of Professional Responsibility.
Second, the District Court applied several provisions of the Disciplinary Rules to Metzger’s conduct, a task raising difficult questions of interpretation. The Code proscribes conflicts of interest and condemns divided loyalties, but it does not resolve the subtle problems arising when outside counsel represents a corporate client whose shareholders, directors, and management are in disagreement.
See Developments in the Law
— Conflicts
of Interest in the Legal Profession,
94 Harv.L.Rev. 1244,1334-1352 (1981). The court found that three of Metz-ger’s activities had violated specific Disciplinary Rules. First, the court concluded that Metzger had violated the attorney’s duty of neutrality (DR 5-105) by participating actively in a dissident group of shareholders without disclosure to management.
The District Court concluded:
From the outset of his representation, Metzger’s attitude toward FG was marked by bad faith, secrecy, and self-dealing. He persistently placed his prerogatives as a shareholder above his fiduciary obligations as an attorney, substituting his own business judgment for that of the corporation he was hired to serve. His behavior fell far short of the high standards imposed on lawyers by common law and by the Code of Professional Responsibility-
Id. at 772.
Having concluded that Metzger had violated common law standards of fiduciary duty, the District Court also broke new ground in imposing a remedy. Without finding that the violations were causally related to pecuniary damage suffered by FG or profit accrued by Metzger, the court ordered Metzger to repay $80,284.12, the entire fee he had received from FG for professional services, exonerated FG from payment of $15,261.95 in outstanding legal bills, and imposed an additional $80,284.12 in punitive damages. Id. at 773. The Dis *772 trict Court cited no District of Columbia cases, and we have discovered none, which award a monetary remedy to a client for an attorney’s breach of fiduciary duty in the absence of proven pecuniary loss to the client or proven financial gain to the attorney. On the other hand, the District of Columbia courts have not foreclosed the possibility that, in an appropriate case, disgorgement of fees might be the appropriate remedy.
On appeal Metzger challenges both the District Court’s retention of pendent jurisdiction over the local fiduciary duty claims and its decision on the merits. We do not reach the merits, because we conclude that, under the circumstances, the District Court abused its discretion in exercising pendent jurisdiction over novel and unsettled questions of District of Columbia law. We vacate the judgment of the District Court and remand with instructions to dismiss after the defendant has waived any applicable statute of limitations in the Superior Court of the District of Columbia and has agreed to forgo evidentiary objections to the depositions, documents, and exhibits admitted into evidence by the District Court. In light of our disposition of the appeal, we dismiss FG’s cross-appeal for prejudgment interest.
II. Pendent Jurisdiction
The Supreme Court’s decision in
United Mine Workers of America v. Gibbs,
Under the criteria set forth in
Gibbs,
the District Court had the power to decide FG’s common law fiduciary claims against Metz-ger. The federal claim based on Section 13(d) of the Securities Exchange Act of 1934 was substantial enough to confer subject matter jurisdiction on the court,
see Gibbs, supra,
A. Factors Guiding the Exercise of Discretion
As the Supreme Court emphasized in
Gibbs,
even if the District Court had the power to determine the pendent claim, “That power need not be-exercised in every case in which it is found to exist. It has consistently been recognized that pendent jurisdiction is a doctrine of discretion, not of plaintiff’s right.”
lies in considerations of judicial economy, convenience and fairness to litigants; if these are not present a federal court should hesitate to exercise jurisdiction over state claims, even though bound to apply state law to them * * *. Needless decisions of state law should be avoided both as a matter of comity and to promote justice between the parties, by pro *773 curing for them a surer-footed reading of applicable law. * * *
Id. 6
In dictum in the
Gibbs
opinion the Court seemed to establish a firm rule for exercise of the District Court’s discretion: “[I]f the federal claims are dismissed before trial, even though not insubstantial in a jurisdictional sense, the state claims should be dismissed as well.”
Id.
Frequently this outcome will be consistent with the general principles cited above. If the federal claims have been resolved at an early stage in the litigation, leaving state claims to the state courts will not necessarily require a wasteful duplication of effort, and a state court will provide a more accurate, authoritative determination of the applicable law.
See Wham-O-Mfg. Co. v. Paradise Manufacturing Co.,
Nevertheless, as a number of federal courts have recognized, ironclad adherence to the
Gibbs
dictum would occasionally dis-serve the basic policies of pendent jurisdiction. If extensive pretrial proceedings have already occurred before dismissal of the federal claims, considerations of “judicial economy, convenience and fairness” may support retention of pendent jurisdiction by the federal court rather than dismissal of state claims, which would require the parties to bring a new civil action in state court. Relying on the Supreme Court’s emphasis on judicial economy and convenience in
Rosado v. Wyman,
B. Judicial Economy, Convenience, and Fairness
In this case the District Court looked solely to judicial economy considerations when it decided to retain pendent jurisdiction over the common law fiduciary claims against defendant Metzger. The court explained that extensive discovery on these causes of action had taken place, that the court was familiar with the relevant facts, and that plaintiff was ready to go to trial on the local law issues. On this basis it concluded that, under the principles enunciated in Gibbs, it should exercise its jurisdiction over the pendent common law claims. JA 262.
The court overestimated the judicial economy and convenience to be gained by retaining pendent jurisdiction. Discovery had been pursued actively during a two-year period, but much of that effort would not need to be duplicated in an action in the District of Columbia courts. The Federal Rules of Civil Procedure permit wide-ranging discovery “to allow a broad search for facts, the names of witnesses, or any other matters which may aid a party in the preparation or presentation of his case.” Advisory Committee Notes, 1946 Amendment to Rule 26, Subdivision (b). Material may be discoverable even if it will be inadmissible at trial, as long as it appears reasonably calculated to lead to discovery of admissible evidence. Federal Rule of Civil Procedure 26(b)(1). In addition, the standards of admissibility for documentary material and other exhibits in the Superior Court are similar to the Federal Rules of Evidence applicable in the District Court. See S. Graae, District of Columbia Statutory and Case Law Annotated to the Federal Rules of Evidence 8.1-10.20 (Young Lawyers Section of Bar Ass’n of District of Columbia 1976). To alleviate FG’s concern that some deposition evidence used in the District *775 Court action might not be admissible in the Superior Court of the District of Columbia, 11 dismissal of the case in federal court will be conditioned on Metzger’s waiver of evidentiary objections to material admitted into evidence by the District Court. See Part III infra.
The expenditure of additional judicial effort after dismissal of the federal claims also undermines the District Court’s determination that convenience and economy favored exercise of pendent jurisdiction over the local law claims. The District Court denied Metzger’s motion to dismiss the common law claims on August 2, 1980. It then set a trial date, entered a pretrial order, and conducted a three-day trial from November 19 to 21,1980.
See
Docket Entries, JA 26-27. After receiving proposed findings of fact and conclusions of law from both parties, the court issued a 54-page memorandum opinion on July 31, 1981. JA 1263-1316,

C. Unsettled Issues of Local Law
In addition, in exercising its discretion to retain pendent jurisdiction the District Court did not take into account the novel and unsettled nature of District of Columbia law regarding the fiduciary duties of an attorney to a client. Yet the importance of this factor was articulated in
Gibbs,
which emphasized that state courts would provide a “surer-footed reading of applicable law,”
[T]he rationale of Gibbs centers upon considerations of comity and the desirability of having a reliable and final determination of the state claim by state courts having more familiarity with the controlling principles and the authority to render a final judgment. * * *
Id.
at 548,
Although the degree of uncertainty in state law is one of several factors that should guide the District Court’s discretion, it should be given considerable weight. As Professor Wechsler has noted, “[Fjederal courts are not the authorized expositors of state law; there is no mechanism by which their errors in such matters can be corrected on appeal by state courts.” Wechsler,
Federal Jurisdiction and the Revision of the Judicial Code,
13 Law & Contemp.Prob. 216, 232 (1948) (cited in
Gibbs,
The desirability of obtaining a “surer-footed reading of applicable law” in state courts weighs especially strongly when the federal claims have been dismissed before trial. In those circumstances, judicial economy factors are diminished and it is more likely that a determination of state law will be unnecessary. It is well within the sound discretion of the District Court to decline to retain pendent jurisdiction over novel issues of state law after pretrial dismissal of federal claims.
See, e.g., Cenco Inc. v. Seid-man & Seidman,
When a District Court reaches out to decide unsettled issues of state law despite the pretrial dismissal of all federal claims, its action may be an abuse of discretion. In
REA Express, Inc. v. Travelers Ins. Co.,
The First Circuit took a similar approach in
Rice v. President & Fellows of Harvard College,
In this case Financial General Bank-shares’ fiduciary duty claim raises issues of District of Columbia law that have never been addressed by the District of Columbia courts. Historically the courts of the states have had the power to regulate admission to the bar and to discipline lawyers. 15 Since reorganization of the courts of the District of Columbia in 1970, the local court system has had the same authority as state courts to establish and enforce standards of professional conduct for attorneys. 16 To deter *778 mine whether plaintiff FG is entitled to relief in this case, a court must decide what standards define a breach of an attorney’s fiduciary duty in a situation giving rise to alleged conflicts of interest and alleged disclosure of client confidences. It must also decide whether Metzger’s conduct violated these standards and whether disgorgement of fees is an appropriate remedy. Although the District Court devoted considerable time, effort, and care to these questions, in a completely unsettled area of local law a federal District Court opinion is no substitute for an authoritative decision by the courts of the District of Columbia.
We conclude that the District Court abused its discretion by failing to take into' account the uncertainty of state law and by proceeding to trial on the local claims after the dismissal of the federal claims.
III. Disposition of the Case
We have concluded that the District of Columbia courts are the proper forum, under the circumstances, for resolution of FG’s claims against defendant Metzger. It is possible that, in the absence of waiver or equitable tolling, FG might be subject to a statute of limitations defense in the Superi- or Court of the District of Columbia. The alleged wrongdoing took place from June ..«1977 to January 1978. At oral argument, however, counsel for appellant Metzger took the position that the District of Columbia statute of limitations had been tolled during the pendency of this action in federal court. To assure that plaintiff FG may avail itself of the local forum, we vacate the judgment of the District Court appealed from in No. 81-1968 and remand with instructions not to dismiss the case until the plaintiff has filed an action in the Superior Court of the District of Columbia and the defendant, has filed in that court a record waiver of any applicable statute of limitations.
See McLaughlin v. Campbell,
In addition, the dismissal should be conditioned on Metzger’s agreement to waive evidentiary objections to documents, exhibits, deposition transcripts, and other material which were admitted into evidence by the District Court in the trial of this action.
See
In light of our disposition of the pendent claims, FG’s cross-appeal in No. 81-1999 for prejudgment interest is dismissed.
Judgment accordingly.
Notes
.
United Mine Workers of America
v.
Gibbs,
. The defendants named in the original complaint, filed February 17, 1978, were Bert Lance, allegedly employed by the Middle Eastern investors as a business consultant; Bank of Credit and Commerce International, a United Kingdom bank allegedly acting on behalf of the investors; Agha Hasan Abedi, president of BCCI; Eugene J. Metzger, an attorney practicing law in Washington, D. C. and appellant in this case; Jackson Stephens, a major FG shareholder, businessman, and commercial banker; Systematics, Inc., a data processing corporation which performed data processing services for banks; Stephens, Inc., an investment banking firm controlled by Stephens; and 25 John Doe defendants believed to be purchasing FG shares. Joint Appendix (JA) 33-35. The amended complaint filed March 21, 1978 added Labelle Lance, Bert Lance’s wife and a shareholder in FG; and five Middle Eastern investors — Sheikh Kamal Adham, a minister of the Saudi Arabian government; Faisal Saud Al-Fu-laij, a citizen of Kuwait; His Royal Highness Sheikh Sultan Bin Zaid Al-Nahyan, the crown prince of Abu Dhabi; Abdullah Darwaish, financial advisor to the royal family of Abu Dha-bi; and Sheikh Mohammed Bin Zaid Al-Nah-yan, younger brother of H.R.H. Sheikh Sultan of Abu Dhabi. JA 67-68.
. The complaint alleged violations of § 13(d) of the Securities Exchange Act of 1934, 15 U.S.C. § 78m(d) (1976), and the regulations promulgated thereunder (requiring persons acquiring beneficial ownership of more than 5% of any class of an issuer’s equity securities to file disclosure statements); §§ 14(d) and 14(e) of the 1934 Act, id. §§ 78n(d) and 78n(e), and the regulations promulgated thereunder (regulating tender offers and prohibiting misstatements and material omissions); and § 10(b) of the 1934 Act, id. § 78j(b), and Rule 10b-5 promulgated thereunder (prohibiting manipulative and deceptive devices and artifices to defraud).
. On July 20, 1978 the District Court granted summary judgment in favor of defendants Jackson Stephens and Stephens, Inc. on the § 13(d) claim. JA 136-139. It also denied summary judgment for plaintiff FG on its fiduciary duty claim against defendant Metzger, appellant in this case, concluding that material facts remained in dispute. JA 140. On August 2, 1978 Metzger moved for summary judgment on the § 13(d) claim, the sole remaining federal cause of action against him. JA 128-132. The District Court took no action on Metzger’s motion.
. The tender offer contemplated by the settlement has now been successfully completed. The Middle Eastern investors are in control of Financial General Bankshares, Inc. Washington Post, April 9, 1982, at C8.
. Other factors set forth in the
Gibbs
opinion to guide exercise of discretion are not germane
to
the case before us: whether the, state issues substantially predominate over the federal claims, whether the state claim is so closely tied to questions of federal policy that the argument for exercise of pendent jurisdiction is particularly strong, and whether there is a likelihood of jury confusion if the state and federal claims are tried together.
. The District Court in this circuit has frequently followed the
Gibbs
dictum. See, e.g.,
Nat’i Tire Wholesale, Inc. v. Washington Post Co.,
. The Court in
Rosado v. Wyman,
. In several cases citing
Rosado v. Wyman, supra
note 8, Courts of Appeals have upheld District Courts’ exercise of pendent jurisdiction over state claims, even though the court conducted further proceedings on the state claims after dismissal or settlement of the federal claims.
State of North Dakota v. Merchants Nat’l Bank & Trust Co.,
In other cases, when the federal claims were dismissed before trial and state claims were simultaneously decided on the merits, the District Court’s exercise of pendent jurisdiction has been upheld.
See, e.g., Meyer v. California & Hawaiian Sugar Co.,
. This court has recognized that
Rosado v. Wyman, supra
note 8, modifies the apparently absolute directive of the
Gibbs
dictum.
See Baurer v. Planning Group, Inc.,
. FG contends that a substantial portion of the evidence against Metzger is contained in the depositions of Agha Hasan Abedi, the president of BCCI and a foreign resident, and other foreign employees of defendant BCCI. These depositions were taken, for the most part, in London. According to FG’s brief, “There is no guarantee that the testimony (by deposition or otherwise) of these foreign individuals could be obtained in any state court action against Metzger, in which they would be non-party witnesses outside the jurisdiction of the state court. Even if they could be deposed as non-party witnesses in a state court action, FG would have been put to enormous delay and expense to recreate a record that already existed in this action.” Reply brief for FG at 43-44.
In response Metzger contends that if the BCCI witnesses were unavailable to testify at trial in Superior Court, their prior recorded testimony would be admissible in Superior Court under the former testimony exception to the hearsay rule. Reply brief for Metzger at 13, citing
