OPINION OF THE COURT
GREENBERG, Circuit Judge.
I. INTRODUCTION
This matter comes on before the court on an appeal by plaintiff Pressman-Gut-man Co., Inc. (“PGI”) from certain orders of the district court disqualifying counsel for PGI and appointing a guardian ad li-tem to replace the administrators of the employee profit-sharing plan on whose behalf PGI initiated this action under the Employee Retirement Income Security Act of 1974 (“ERISA”), 29 U.S.C. § 1001 et. seq. Inasmuch as PGI recognizes that we may lack appellate jurisdiction, it has filed a petition for a writ of mandamus or prohibition (“PL’s pet.”) invoking our original jurisdiction and seeking to prevent enforcement of the orders from which it appeals. For the reasons explained below, we will dismiss the appeal for lack of jurisdiction and deny the petition for a writ of mandamus.1
II. FACTUAL AND PROCEDURAL HISTORY
PGI is the employer sponsor and named fiduciary of the Pressman-Gutman Co., Inc. Profit Sharing Plan (the “Plan”), on whose behalf PGI in such capacities brought this action on November 13, 2002, against First Union National Bank (“First Union”) and ForeFront Capital Advisors, LLC (“ForeFront”) (collectively “defendants”). In the action PGI sought to recover damages on behalf of the Plan and its participants and beneficiaries that PGI claimed the Plan sustained as a result of defendants’ mismanagement of the Plan’s assets.2 In sum, PGI alleged that First Union, as trustee of the Plan, and ForeFront, as First Union’s sub-advisor, breached fiduciary duties they owed to the Plan by pursuing an imprudent investment course contrary to various representations made to PGI on which it justifiably relied. In initiating this litigation, PGI acted by and through its secretary, Alvin Gutman, and its president, James Gutman, Alvin’s son, then the sole members of the Plan’s Administrative Committee. At the time that PGI filed this action, the law firm of Hamburg & Golden, P.C. (“H & G”) represented it.
On April 22, 2003, First Union filed a third-party complaint against the Gutmans asserting that they had participated in and consented to defendants’ investment decisions and alleging that the Gutmans breached fiduciary duties owed to the Plan under ERISA by failing to take appropri[388]*388ate action with respect to the Plan’s investments and assets.3 First Union further alleged that the Gutmans were negligent in the discharge of their fiduciary duties. Therefore, First Union sought judgment in its favor against the Gutmans “for contribution and/or indemnity, in the event that First Union is found liable to Plaintiff for any damages.” J.A. at 252.
The Gutmans retained H & G as their attorneys to defend them against the third-party complaint. This retention led First Union to file a motion on August 1, 2003, to disqualify H & G as attorneys in this case alleging that it had an “inherent and unwaivable conflict of interest resulting from [¶] & G’s] joint representation of both Plaintiff and Third-Party Defendants.” 4 J.A. at 277. The district court denied the motion, finding that there was insufficient evidence to disqualify H & G at that time. ForeFront later filed a renewed motion, in which First Union joined, to disqualify H & G from representing both the plaintiff, PGI, and the third-party defendants, the Gutmans, asserting that new facts had emerged during the course of discovery to bolster the case for disqualification.5
Before the district court ruled on the renewed motion to disqualify H & G, the Gutmans filed a motion for summary judgment on the third-party complaint that the district court denied on May 13, 2004. The district court held that First Union raised triable issues concerning the Gut-mans’ control over the Plan’s assets and management, explaining that “to the extent that the Gutmans may have used their positions to cause First Union and/or ForeFront to relinquish their independent discretion with respect to management of the assets and exercised actual control over the assets, the Gutmans may be liable as fiduciaries for investment decisions.” J.A. at 1770-71 n. 1 (internal citations omitted).
After denying the Gutmans’ motion for summary judgment, the district court considered ForeFront’s renewed motion to disqualify H & G. On August 30, 2004, the district court ordered that H & G be “disqualified from serving as counsel for third-party defendants” and further ordered that all pending motions be stayed for 30 days to allow the Gutmans to obtain new counsel. J.A. at 3. The court, however, did not disqualify H & G from representing PGI. In a memorandum accompanying the order, the court analyzed the conflict issue under Rule 1.7 of the Pennsylvania Rules of Professional Conduct (“Pa. R.P.C.”), as the rule then read, which was applicable in the district court and which pertains to simultaneous representation of clients with adverse interests,6 and determined that [389]*389disqualification was warranted because “plaintiffs potential claims against third-party defendants present directly adverse interests.” J.A. at 7. Specifically the court explained:
This court finds it unreasonable for [¶] & G] to believe it can adequately represent both plaintiff and third-party defendants .... The court’s review of the record reveals that plaintiff has not consented to [¶] & G’s] joint representation of plaintiff and third-party defendants. Therefore, H & G is disqualified from representing third-party defendants in this action.
J.A. at 7. On September 17, 2004, Attorney Christopher M. Tretta filed a notice of appearance on behalf of the Gutmans, and H & G withdrew as their counsel four days later. On September 8, 2004, ForeFront and First Union filed motions seeking reconsideration or clarification of the August 30, 2004 order as they believed that the court should have disqualified H & G completely while the order only disqualified H & G from representing the Gutmans as third-party defendants. In addition, the defendants requested that the court appoint a “trustee ad litem” for the Plan as they argued, inter alia, that the Gutmans, who had been in control of the Plan’s litigation, could not represent its interests adequately.
1. The November 30, 2004 Order
On November 30, 2004, the district court granted defendants’ motions which sought to disqualify H & G completely and asked the court to appoint a trustee ad litem to replace the Gutmans as representatives of the Plan. At that time the court vacated its August 30, 2004 order. Notwithstanding the fact that two months earlier H & G had withdrawn from representing the Gut-mans and new counsel had entered an appearance on their behalf, the district court reviewed “the record as it existed on August 30, 2004,” J.A. at 19, the date that the court originally partially disqualified H & G, and again analyzed the conflict issue under Pa. R.P.C. 1.7. The district court explained that
[¶] & G] must also be disqualified from representing the profit-sharing plan as plaintiff. Because of [¶] & G’s] duty of loyalty to the Gutmans, who it represented on August 30, 2004, [¶] & G] could not recommend to the [P]lan that it act against the Gutmans, as well as, or instead of, First Union and ForeFront. ... Based on [¶] & G’s] duty of loyalty to the Gutmans, who may well be liable for the [P]lan’s losses, I conclude that it was unreasonable for [¶] & G] to believe that it could adequately represent the [P]lan. Moreover, since only the Gutmans represented the [P]lan in this action, I find that any consent given by the [P]lan to [¶] & G] for [¶] & G’s] continued representation of the [P]lan was invalid.
J.A. at 19. The district court based its disqualification order, in part, on the circumstance that it found that there was “no record of disclosure and waiver,” and be[390]*390cause of what it regarded as the “noteworthy” fact that H & G “has never once produced any evidence that the members of the [P]lan have any idea about a possible conflict, let alone full disclosure and waiver.” J.A. at 22. The court thus disqualified H & G completely.
Notably, the district court further concluded that “the Gutmans may well not be able to fulfill their duties as administrators and fiduciaries of the plan because of their potential liability.” J.A. at 23. In this regard the court explained:
Because the Gutmans may be liable to the [P]lan, the duty to the [P]lan may include presenting claims against the Gutmans. However, because the Gut-mans have an interest in protecting themselves from liability, the Gutmans are not likely to act against themselves for the benefit of the [P]lan, and the [PJlan’s avenues for obtaining recovery may be adversely affected. Accordingly, I will appoint a guardian ad litem who will replace the Gutmans and serve as administrator of the [PJlan for the limited purpose of this lawsuit. The guardian ad litem will, in turn, appoint new counsel for the [P]lan.
Id. at 23 (emphasis added). The court supported its decision to appoint a guardian ad litem by explaining that Fed.R.Civ.P. 17(c) gave it “the power to order the appointment of a representative for a party whose interests may not be adequately represented.” See J.A. at 23 n. 6.
Even though the district court had stated its intention to appoint a guardian ad litem who would retain new counsel for it, PGI retained A. Richard Feldman as counsel to replace H & G, and Feldman filed a notice of appearance on December 14, 2004. Feldman then promptly filed a motion requesting the district court to reconsider its November 30, 2004 order.7
2. The December 15, 2004 Order
By order entered December 15, 2004, the district court appointed Louis R. Pichi-ni “as guardian ad litem for [the Plan] for the limited purpose of this lawsuit.” J.A. at 31. The court further ordered PGI to provide Pichini with contact information for all members of the Plan, explaining that “Mr. Pichini shall contact the members ... for the purpose of retaining an attorney to advise the Plan regarding this litigation and to represent the Plan in this litigation.” J.A. at 31-32.
In a Memorandum and Order entered December 23, 2004, the district court denied PGI’s motion to reconsider. The court explained that PGI’s arguments discussed “the legality of removing a fiduciary under ERISA,” but that its “December 15 order did not remove any fiduciary.” J.A. at 37. Instead, according to the court, “[a]t most, the December 15 order limits the ability of the Gutmans to direct the efforts of the Plan in this discrete lawsuit because they have themselves been sued in their capacities as managers or fiduciaries of the Plan.” J.A. at 36. In [391]*391another order also entered December 23, 2004, the court denied PGI’s request for an extension of time in which to appeal the November 30, 2004 and December 15, 2004 orders inasmuch as, in the court’s view, the orders were not appealable.
On December 30, 2004, PGI filed a notice of appeal, seeking review of: (1) the November 30, 2004 order disqualifying H & G from representing PGI and stating that the court intended to appoint a guardian ad litem for the Plan; (2) the December 15, 2004 order appointing Pichini guardian ad litem for the Plan; (3) the December 23, 2004 order denying PGI’s motion to reconsider the December 15, 2004 order; and (4) the December 23, 2004 order denying PGI’s motion for an extension of time in which to appeal.8
In the alternative, “in the event that appellate jurisdiction is found lacking,” PGI filed a petition for a writ of mandamus in this court under 28 U.S.C. § 1651 “for the purpose of correcting the District Court’s unauthorized exercise of judicial power.” Pl.’s pet. at 2, 13. PGI submits that we should issue a writ of mandamus because the decisions of the district court “are indefensible and beyond its power to achieve.” Pl.’s pet. at 15. No party or attorney has appealed from or otherwise challenged the August 30, 2004 order precluding H & G from representing the Gut-mans.
On March 29, 2005, we consolidated PGI’s petition for mandamus with its appeal, and by this opinion we adjudicate both proceedings.9
III. JURISDICTION
The district court had jurisdiction over this matter under 28 U.S.C. § 1331 and section 502 of ERISA, 29 U.S.C. § 1132(e). The parties dispute whether we have appellate jurisdiction. PGI contends that the orders appointing a guardian ad litem and disqualifying H & G amount to an injunction immediately, appealable under 28 U.S.C. § 1292(a)(1) or, in the alternative, constitute the appointment of a receiver immediately appealable under 28 U.S.C. § 1292(a)(2). As a further alternative ground for our exercise of appellate jurisdiction at this time, PGI submits that the orders appointing a guardian ad litem are appealable under the collateral order doctrine the Supreme Court recognized in Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949), and that we have pendent appellate jurisdiction over the order of disqualification of H & G. Defendants contend that we do not have appellate jurisdiction and thus we should dismiss the appeal. We unquestionably, however, have jurisdiction over PGI’s petition for a writ of mandamus [392]*392under the All Writs Act, 28 U.S.C. § 1651, and defendants do not contend otherwise.
IV. DISCUSSION
1. Appellate Jurisdiction
We point out at the threshold of our discussion, that we are obliged to determine whether we have jurisdiction over PGI’s appeal before we reach the merits of its various challenges to the district court orders through the exercise of our appellate jurisdiction, and that if we do not have jurisdiction we cannot reach the merits of the appeal. See Steel Co. v. Citizens for a Better Env’t, 523 U.S. 83, 93-94, 118 S.Ct. 1003, 1012, 140 L.Ed.2d 210 (1998); Firestone Tire & Rubber Co. v. Risjord, 449 U.S. 368, 379, 101 S.Ct. 669, 676, 66 L.Ed.2d 571 (1981) (“A court lacks discretion to consider the merits of a case over which it is without jurisdiction[.]”); Sheet Metal Workers’ Int’l Ass’n Local 19 v. Herre Bros. Inc., 201 F.3d 231, 237 (3d Cir.1999). Of course, the jurisdictional problem is the result of the undeniable fact that the district court has not entered a final decision as that term conventionally is understood under 28 U.S.C. § 1291, the basis on which a court of appeals usually exercises appellate jurisdiction. For the reasons we explain below, we find that we do not have appellate jurisdiction at this time, and consequently we will dismiss the appeal.
A. 28 U.S.C. § 1292(a)(1)
PGI argues that the orders entered November 30, 2004, and December 15, 2004, are appealable with respect to the removal of the Gutmans, the appointment of the guardian ad litem, and the removal of H & G, pursuant to 28 U.S.C. § 1292(a)(1), which grants the courts of appeals jurisdiction over appeals from “[ijnterlocutory orders ... granting, continuing, modifying, refusing or dissolving injunctions ... except where a direct review may be had in the Supreme Court.” According to PGI, though the orders it challenges lack the formal trappings of injunctive orders, nevertheless “[bjecause those Orders prohibited [PGI] from allowing its duly appointed profit sharing plan administrators to continue to exercise any authority or control over [PGI’s] lawsuit, including the selection of replacement counsel, the Orders amounted to a grant of an injunction.” Appellant’s juris, br. at 23; see also Appellant’s br. at 54-56. This argument lacks merit.
An “injunction” for the purposes of section 1292(a)(1) is an order “[1] directed to a party, [2] enforceable by contempt, and [3] designed to accord or protect ‘some or all of the substantive relief sought by the complaint’ in more than a [temporary] fashion.” Cohen v. Bd. of Trustees, 867 F.2d 1455, 1465 n. 9 (3d Cir.1989) (en banc) (quoting Wright & Miller, et al., Federal Practice and Procedure § 3922, at 29 (1977)); see also Saudi Basic Indus. Corp. v. Exxon Corp., 364 F.3d 106, 110 (3d Cir.2004). We have held that section 1292(a)(1) “should be construed narrowly so as not to swallow the final-judgment rule.” Hershey Foods Corp. v. Hershey Creamery Co., 945 F.2d 1272, 1276 (3d Cir.1991).
In this case, the district court has not granted or denied all or part of the substantive relief sought by any party in this action. We find unpersuasive PGI’s contention that because, as the district court explained, the orders replacing the Gutmans with a guardian ad litem were intended to prevent adverse effects upon “the [P]lan’s avenues for obtaining recovery,” see J.A. at 23, the orders can be said “to protect” the substantive relief sought by PGI and therefore granted injunctive relief. See Appellant’s juris, br. at 25-26; [393]*393Appellant’s br. at 54-56. Such a broad reading of section 1292(a)(1) would undermine the “limited exception to the final judgment rule” that section 1292(a)(1) carves out. See Hershey Foods Corp., 945 F.2d at 1276 (internal quotation marks and citation omitted). Moreover, even accepting PGI’s reasoning, there is no connection between the substantive relief PGI is seeking in the district court and the essentially procedural relief it seeks here. In this regard we reiterate our observations from the outset of this opinion, i e., that PGI has brought this action against defendants to recover damages on account of their alleged mismanagement of the Plan’s assets whereas this appeal is from an order disqualifying counsel for PGI and appointing a guardian ad litem to replace the administrators of the Plan in this litigation.
Instead of being injunctive in character, the orders from which PGI appeals are better understood as being “restraints or directions ... concerning the conduct of parties or them counsel,” unrelated to the substantive relief sought. Id. at 1278 (quoting Int’l Prod. Corp. v. Koons, 325 F.2d 403, 406 (2d Cir.1963)). We have deemed orders of such character to fall outside of section 1292(a)(1). Id. Moreover, if the court issued the orders “to protect and maximize the Plan’s recovery of damages,” as PGI claims, Appellant’s br. at 55, their practical effect is less like the effect flowing from an injunction and more like the effect created by traditional interim security orders, such as orders granting a writ of replevin or attachment pending disposition of an action which fall outside the scope of section 1292(a)(1). See, e.g., Nutrasweet Co. v. Vit-Mar Enters., Inc., 176 F.3d 151, 154 (3d Cir.1999). Overall, it is clear that we do not have jurisdiction under section 1292(a)(1).
B. 28 U.S.C. § 1292(a)(2)
PGI next argues that the orders entered November 30, 2004, and December 15, 2004, are appealable pursuant to 28 U.S.C. § 1292(a)(2), which provides for appeals from the appointment of a receiver. But section 1292(a)(2) “is interpreted narrowly to permit appeals only from the three discrete categories of receivership orders specified in the statute, namely [1] orders appointing a receiver, [2] orders refusing to wind up a receivership, and [3] orders refusing to take steps to accomplish the purposes of winding up a receivership.” SEC v. Black, 163 F.3d 188, 195 (3d Cir.1998). PGI asserts that “[ajlthough the Court characterized Mr. Pichini as a ‘guardian ad litem,’ the court has in fact appointed a receiver to safeguard the Plan’s property interest in its causes of action for damages.” Appellant’s br. at 48 (footnote omitted). We find this argument unpersuasive.
As is true for a determination of whether an order is appealable under section 1292(a)(1), the label used by the district court is not dispositive in a determination of the appealability of an order under section 1292(a)(2). See United States v. Sylacauga Props., Inc., 323 F.2d 487, 490 (5th Cir.1963) (“A receiver by any other name, or by no name, is still a receiver.”). In determining whether a receiver has been appointed, a court must take into account “the purposes of the receivership and the extent of the powers possible in the situation.” 16 Wright, Miller & Cooper, Federal Practice and Procedure: Jurisdiction 2d § 3925, at 220 (1996). In this regard, PGI recognizes that a receiver “take[s] possession of and preserves, pendent lite, and for the benefit of the party ultimately entitled to it, the fund or property in litigation.” FTC v. World Wide Factors, Ltd., 882 F.2d 344, 348 (9th Cir.1989) (internal quotation marks and citation omitted).
The powers of the guardian ad litem in this case, however, are unlike the powers [394]*394given the officers in the cases PGI cites in which courts have given receivers control over propei-ty and have tasked the receivers with preserving it. Thus, in World Wide Factors, 882 F.2d at 348, a special master was, in reality, a receiver for certain purposes insofar as the master was ordered to account for and preserve the assets of the defendant to be available at time of trial in the event the defendant was found liable in the action. In Sylacauga Properties, 323 F.2d at 490, in an action to foreclose a mortgage which included a provision for the appointment of a receiver during a foreclosure proceeding, the court appointed a receiver to receive and collect rents and to preserve the property pending resolution of the dispute. Clearly, World Wide Factors and Sylacau-ga Properties differ from this case because we see no suggestion here that the Plan’s assets must be “preserved” or otherwise managed by the guardian ad litem pending litigation.
It is, of course, significant that the district court narrowly circumscribed the role of the guardian ad litem, explaining in its November 30, 2004 order that it planned “[to] appoint a guardian ad litem who will replace the Gutmans and serve as administrator of the [P]lan for the limited purpose of this lawsuit, ” J.A. at 23 (emphasis added). The district court, in fact, promptly made the appointment. In asserting that it has suffered a “substantial intrusion” on its property rights in its cause of action, see Appellant’s juris, br. at 19-20, PGI overstates the role of the guardian ad li-tem by seizing upon the word “replace” used by the district court and ignoring the phrase that expressly limits the role of the guardian to “the limited purpose of this lawsuit.” J.A. at 23. The district court reiterated this express limitation in its subsequent orders of December 15, 2004, see J.A. at 31-32 (appointing Pichini “guardian ad litem for [the Plan] for the limited purpose of this lawsuit”) (emphasis added), and of December 23, 2004, see J.A. at 35-36 (explaining that guardian ad litem does not replace the Gutmans as Plan administrators but merely “limits the ability of the Gutmans to direct the efforts of the Plan in this discrete lawsuit”) (emphasis added). There is no question that the functions of the guardian ad litem in this case fall far short of those of a receiver for in each of its several orders the district court expressly limited the role of the guardian ad litem and otherwise did not disturb the Gutmans in their capacity as fiduciaries and administrators of the Plan.
Lastly, with respect to the applicability of section 1292(a)(2), we find unpersuasive PGI’s argument that the guardian ad litem is, in fact, a receiver because he is “the recipient of a court-ordered transfer of another’s property” in the form of PGI’s cause of action. Appellant’s br. at 48; Appellant’s juris, br. at 19. We reject PGI’s assertion that it is. of no consequence that “in the usual case, the property is the subject matter of the litigation,” whereas here, “the property is the cause of action itself.” Appellant’s juris, br. at 19 n. 8. If we adopted PGI’s expansive interpretation of what type of officer is a receiver, we effectively would eliminate the distinction between guardians ad litem and receivers, and, for that matter, between fiduciaries and receivers. We have no intention of doing any such thing.10
[395]*395We primarily have considered the appointment of the guardian ad litem in our section 1292(a)(2) discussion, but we have not overlooked PGI’s contention that the scope of review under that section also includes the order disqualifying H & G. Of course, inasmuch as we do not find that section applicable even as to the appointment of the guardian ad litem, the section does not give us jurisdiction over an appeal from the disqualification of H & G. On this point we state only that it could not be argued seriously that in itself an order disqualifying an attorney has anything to do with a receivership. Consequently, the disqualification order could not possibly be within section 1292(a)(2).
C. Collateral Order Doctrine
As a “further alternative ground for jurisdiction,” PGI contends that the district court’s orders appointing a guardian ad litem are immediately appealable under 28 U.S.C. § 1291 via the collateral order doctrine recognized in Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528. Appellant’s juris, br. at 28; see also Appellant’s br. at 57-60.11 Under the collateral order doctrine, the authority of the courts of appeals in section 1291 to review “all final decisions,” “includes appellate jurisdiction over a narrow class of decisions that do not terminate the litigation, but are sufficiently important and collateral to the merits that they should nonetheless be treated as final.” Will v. Hallock, — U.S. -, 126 S.Ct. 952, 956, 163 L.Ed.2d 836 (2006) (internal quotation marks omitted). For the collateral order doctrine to apply, the order in question must: “(1) conclusively determine the disputed question, (2) re[396]*396solve an important issue completely separate from the merits of the action, and (3) be effectively unreviewable on appeal from a final judgment.” Id. at 957 (internal quotation marks and citation omitted).
The three criteria that must be met for the collateral order doctrine to apply are “stringent,” and the Supreme Court repeatedly has emphasized the doctrine’s “modest scope.” Id.; see also Digital Equip. Corp. v. Desktop Direct, Inc., 511 U.S. 863, 868, 114 S.Ct. 1992, 1996, 128 L.Ed.2d 842 (1994) (“[W]e have ... repeatedly stressed that the ‘narrow’ exception should stay that way and never be allowed to swallow the general rule ... that a party is entitled to a single appeal, to be deferred until final judgment has been entered[.]”) (internal citation omitted). We have explained that a failure to meet any one of the three factors renders the doctrine inapplicable as a basis for appeal, no matter how compelling the other factors may be. Virgin Islands v. Hodge, 359 F.3d 312, 320 (3d Cir.2004).
Clearly the collateral order doctrine is inapplicable here because the orders PGI challenges do not involve an issue completely separate from the merits of the action. On the contrary, the orders appointing a guardian ad litem for the Plan are enmeshed with the factual and legal issues comprising the third-party claim against the Plan administrators alleging breach of fiduciary duties owed to the Plan, and review of the orders would draw this court into the substance of the third-party complaint. In its order of November 30, 2004, the district court recognized as much, explaining that its denial of the third-party defendants’ motion for summary judgment on the basis that genuine issues of material fact existed “concerning the Gutmans’ control over the plan assets and investment decisions” was “significant to the disqualification issue.” J.A. at 14.
PGI cites Collinsgru v. Palmyra Board of Education, 161 F.3d 225, 229 (3d Cir.1998), to illustrate an order that raises an issue completely separate from the merits of the litigation, but Collinsgru is distinguishable and provides no support for PGI’s position. In Collinsgru, we concluded that we had jurisdiction under the collateral order doctrine over an order dismissing a child’s claims under the Individuals with Disabilities Education Act (“IDEA”) after his parents were denied permission to represent him in the district court. Id. at 230. We explained that the issue of whether the appellants could represent their son in the district court was completely separate from the merits of the underlying IDEA claim alleging inappropriate denial of special education services. Id. But Collinsgru did not present any question of whether the parents adequately could represent the interests of their son. Moreover, the son did not have any claims against his parents, and the case did not otherwise raise the specter of conflicting interests between parents and child. Thus, the procedural context here renders Collinsgru inapposite.
We have not overlooked our discussion with respect to section 1292(a)(1) in which we pointed out that there is no connection between the relief PGI sought in bringing this action and the effect of the district court orders from which PGI now appeals. That observation is not in any way inconsistent with our conclusion that the orders from which the appeal has been taken relate to the substantive issues raised by the third-party complaint. In this regard we point out that the Cohen v. Board of Trustees test indicates that the grant or denial of relief can be injunctive for purposes of section 1292(a)(1) only if it is designed to accord or protect some or all of the substantive relief sought in the ac[397]*397tion. Here, on the other hand, we are concerned with procedural steps leading to a substantive disposition rather than the disposition itself.
We realize that one of the criteria for finding the collateral order doctrine to be applicable is that the issue to be considered on the appeal is important. Nevertheless, neither the vagaries of this particular case nor the importance of rights purportedly compromised warrants us reaching a different result for the Supreme Court has “consistently eschewed a case-by-ease approach to deciding whether an order is sufficiently collateral.” Cunningham v. Hamilton County, 527 U.S. 198, 206, 119 S.Ct. 1915, 1921, 144 L.Ed.2d 184 (2000); see also Digital Equip. Corp., 511 U.S. at 868, 114 S.Ct. at 1996 (“[T]he issue of appealability under § 1291 is to be determined for the entire category to which a claim belongs.... ”). The importance of the issue comes into consideration only if the issue is completely separate from the merits of the action, and here it is not separate. Thus, even if PGI somehow has a more compelling objection to the appointing of a guardian ad litem than the “ordinary” party seeking to appeal from an order making such an appointment, controlling precedent counsels against such a case-by-case application of the collateral order doctrine. See Bacher v. Allstate Ins. Co., 211 F.3d 52, 57 (3d Cir.2000).
Finally, we see no reason to conclude that the orders appointing the guardian ad litem effectively will be unreviewable on appeal from a final judgment. In our view, the appointment of a substitute Plan representative to replace the otherwise conflicted Plan administrators is similar to an order disqualifying conflicted counsel, which is not appealable under the collateral order doctrine. See Richardson-Merrell, Inc. v. Roller, 472 U.S. 424, 438-39, 105 S.Ct. 2757, 2765, 86 L.Ed.2d 340 (1985). But just as a party suffering' an unsatisfactory judgment with substituted counsel can challenge an order disqualifying its earlier choice of counsel on an appeal following the entry of final judgment, so, too, will the Plan be able to appeal should it suffer an unsatisfactory judgment with a substitute Plan representative.12 See Comuso v. Nat’l R.R. Passenger Corp., 267 F.3d 331, 336-37 (3d Cir.2001).13
We recognize that sometimes essentially procedural orders can be effectively unre-[398]*398viewable on appeal from a final judgment, and that in such situations we have allowed earlier appeals predicating our jurisdiction on the collateral order doctrine. Perhaps our leading case within that category is In re Ford Motor Co., 110 F.3d 954, 963 (1997), in which we allowed an immediate appeal from an order denying a motion seeking the protection from release on discovery of documents claimed to be protected by the attorney-client privilege or as work product. We reached this result because a delay in allowing the appeal would have permitted the very disclosure that the appellant claimed applicable rules precluded. See also Whiting v. Lacara, 187 F.3d 317 (2d Cir.1999) (per curiam) (jurisdiction order under collateral order doctrine for order denying attorney’s motion to withdraw).
This case, however, is different from Ford Motor Co. It well may be that if this litigation goes ahead in the control of the guardian ad litem and replacement counsel and there is a reversal after final judgment, events in this litigation before the appeal could have some impact on later proceedings in the district court.14 Yet such an effect is always possible following a reversal, but it differs in character from the situation in Ford Motor Co. where the right to be protected has been irretrievably lost when the materials are released.
2. Petition for Writ of Mandamus
Dismissal of PGI’s interlocutory appeal for want of jurisdiction does not end our consideration of this case for, as we explained above, PGI also filed a petition for a writ of mandamus under the All Writs Act, 28 U.S.C. § 1651, which we have consolidated with its appeal. In brief, PGI asserts that we should issue a writ of mandamus to correct the district court’s errors in replacing the Gutmans with a guardian ad litem and disqualifying H & G from representing PGI.
We have the power to issue a writ of mandamus pursuant to 28 U.S.C. § 1651(a), “in exceptional cases where the traditional bases for jurisdiction do not apply.” In re Pasquariello, 16 F.3d 525, 528 (3d Cir.1994). However, as we have explained, “mandamus is not a mere alternative to an appeal” and instead properly is viewed as a “safety valve in the final-judgment rule” providing a “drastic remedy ... only in extraordinary circumstances in response to an act amounting to a judicial usurpation of power.” In re Briscoe, 448 F.3d 201, 211 (3d Cir.2006) (internal quotation marks and citations omitted). But mandamus is an extraordinary remedy, and “[a]s the adjective ‘extraordinary’ implies ... courts of appeals must be chary in exercising that power,” so as to avoid having mandamus used as a substitute for appeal. In re Sch. Asbestos Litig., 977 F.2d 764, 772 (3d Cir.1992). “Mandamus is disfavored because its broad use would threaten the policy against piecemeal appeals.” Id. (citing Kerr v. United [399]*399States Dist. Court, 426 U.S. 394, 403, 96 S.Ct. 2119, 2124, 48 L.Ed.2d 725 (1976)).
Courts have used mandamus “to confine an inferior court to a lawful exercise of its prescribed jurisdiction or to compel it to exercise its authority when it is its duty to do so.” In re Sch. Asbestos Litig., 977 F.2d at 773 (quoting Roche v. Evaporated Milk Ass’n, 319 U.S. 21, 26, 63 S.Ct. 938, 941, 87 L.Ed. 1185 (1943)). Mandamus may lie to prevent a district court from usurping a power that it lacks and to rectify clear abuses of discretion. Id.; see also Hahnemann Univ. Hosp. v. Edgar, 74 F.3d 456, 461 (3d Cir.1996) (mandamus constitutes a “drastic remedy that a court should grant only in extraordinary circumstances in response to an act amounting to judicial usurpation of power”) (internal quotation marks omitted). Three conditions must be satisfied for the issuance of a writ of mandamus: (1) there must be “no other adequate means to attain the relief sought;” (2) the right to issuance of the writ must be “clear and indisputable;” and (3) the issuing court, in the exercise of its discretion, must be satisfied that “the writ is appropriate under the circumstances.” In re Briscoe, 448 F.3d at 212 (citing Cheney v. United States Dist. Court, 542 U.S. 367, 380-81, 124 S.Ct. 2576, 2587, 159 L.Ed.2d 459 (2004)).15
A. Appointment of Guardian ad litem
PGI cannot demonstrate that its claimed right to a writ of mandamus is “clear and indisputable” with respect to the several orders replacing the Gutmans with a guardian ad litem for purposes of the litigation. PGI devotes a substantial portion of its briefs in this court to arguing that the district court improperly removed the Gutmans as Plan administrators absent any finding of substantial breach of fiduciary duty, as required by ERISA sections 409(a) and 502(a)(2), 29 U.S.C. §§ 1109(a), 1132(a)(2).16 But PGI’s argument is misplaced because the district court did not apply ERISA sections 409(a) and 502(a)(2) for the excellent reason that it did not remove a fiduciary, and thus the sections were not applicable. Our conclusion in this regard cannot be avoided because, despite PGI’s persistent effort to recast the district court’s orders as removing the Gutmans from their capacity as ERISA fiduciaries, the court made clear in [400]*400express terms that the orders at issue did not remove them as Plan fiduciaries or otherwise disturb their role as Plan administrators. Instead, the orders merely suspended their role managing this litigation on behalf of the Plan. See, e.g., J.A. at 36 (clarifying that role of guardian ad litem is limited “to direct[ing] the efforts of the Plan in this discrete lawsuit ”) (emphasis added).
Moreover, PGI recognizes the limited nature of the appointment in its petition for mandamus, conceding that “[w]hile it is true that the Court did not remove the Gutmans completely from sowing as members of the Plan’s Administrative Committee, it is undeniable that it removed them in part.” Pl.’s pet. at 25 (emphasis added). This so-called removal “in part” is a far cry from the removal of an ERISA fiduciary governed by section 409(a), particularly when, as here, the only administrative capacity affected is the Gut-mans’ ability to direct litigation in which their interests may conflict with those of the Plan they purport to represent. Section 409(a), by its terms, pertains to the sanction of removal in cases where a fiduciary breaches any of the responsibilities, obligations, or duties imposed by ERISA. See 29 U.S.C. § 1109(a). Here, however, the district court’s appointment of a guardian ad litem was not a sanction at all but rather was a prophylactic measure to ensure adequate representation for the real party-in-interest, the Plan. Thus, the district court removed the Gutmans without finding that they breached their duties in any way.
As a leading treatise explains, federal courts always have had the power to appoint special representatives for persons whose general representative has conflicting interests. 6A Wright, Miller & Kane, Federal Practice and Procedure: Civil 2d § 1570, at 498 (1990). Moreover, the common law of trusts, “which offers a starting point for analysis of ERISA unless it is inconsistent with the language of the statute, its structure, or its purposes,” Harris Trust & Sav. Bank v. Salomon Smith Barney, Inc., 530 U.S. 238, 250, 120 S.Ct. 2180, 2189, 147 L.Ed.2d 187 (2000) (internal citations and quotation marks omitted), contemplates the appointment of an independent representative to replace a conflicted trustee. See, e.g., Getty v. Getty, 205 Cal.App.3d 134, 140-42, 252 Cal. Rptr. 342 (Cal.Ct.App.1988) (affirming appointment of trustee ad litem with limited powers to conduct discrete litigation in lieu of conflicted trustee).
Nor can we dismiss as unfounded the district court’s determination that a potential conflict of interest necessitates a special representative for the Plan in this litigation. In one noteworthy case, the Court of Appeals for the Fifth Circuit remarked that an ERISA fiduciary violates sections 404(a)(1) and 406(b)(2) as a matter of law by actively participating in the decision-making process concerning whether to pursue legal remedies against himself. Iron Workers Local No. 272 v. Bowen, 624 F.2d 1255, 1261 (5th Cir.1980). This case presents obvious potential for a similar conflict of interest inasmuch as the Plan’s administrators have been sued in their capacities as Plan fiduciaries in a third-party complaint, thus potentially compromising their ability to act “solely in the interest of the participants and beneficiaries” of the Plan. 29 U.S.C. § 1104(a)(1). By appointing a guardian ad litem as a prophylactic measure, the district court sought to obviate a problem like that which occurred in Iron Workers Local No. 272. While the appointment of a guardian ad litem later may prove to have been an unnecessary precaution should the third-party claims against the Gutmans fail, the potential problems created by the Gut-[401]*401mans acting for PGI are such that, whatever we may conclude on a later appeal if there is one, PGI hardly can be said to possess a present “clear and indisputable” right to extraordinary mandamus relief with respect to the appointment.17
PGI raises various due process claims challenging the appointment of a guardian ad litem but its arguments in this respect lack merit, and we need not belabor them. With regard to procedural due process, PGI had adequate notice of and an opportunity to respond to the contemplated appointment of an independent representative for the Plan. Indeed, the district court when denying reconsideration of the orders appointing Pichini noted that PGI “did not respond in substance to the requests heard earlier ... to disqualify counsel and appoint an independent party to represent the [P]lan,” and instead chose to “attack[ ] the motives of the defendants and vehemently denfy] the existence of any conflict of interest.” J.A. at 37.18 Nor can we conclude that the appointment of a guardian ad litem violates substantive due process because we reject PGI’s assertion that the appointment of a non-conflicted representative for the Plan was “conduct that shocks the conscience and violates the decencies of civilized conduct.” County of Sacramento v. Lewis, 523 U.S. 833, 846, 118 S.Ct. 1708, 1717, 140 L.Ed.2d 1043 (1998) (internal quotation marks and citation omitted); United Artists Theatre Circuit, Inc. v. Township of Warrington, 316 F.3d 392, 399-402 (3d Cir.2003). In point of fact we regard the substantive due process argument as insubstantial.19
B. Disqualification ofH & G
PGI correctly notes that the Supreme Court has left open the door to mandamus relief in certain cases involving erroneous disqualification of counsel. See Richardson-Merrell, Inc., 472 U.S. at 435, 105 S.Ct. at 2763 (citing Firestone Tire & Rubber Co., 449 U.S. at 378 n. 13, 101 S.Ct. at 676 n. 13); see also In re Sandahl, 980 F.2d 1118, 1121-22 (7th Cir.1992) (granting petition for writ of mandamus to vacate “patently erroneous” disqualification order). It does not follow, however, that merely because such an extraordinary writ may be available in some instances when counsel has been disqualified, that it is available here. Clearly, each petition for a writ of mandamus must be considered taking into account the circumstances surrounding the particular disqualification. Here, as with its challenge to the appointment of a guardian, PGI cannot demonstrate that its right to a writ of mandamus [402]*402to override the disqualification of counsel is “clear and indisputable.”
We have not overlooked a belated challenge that PGI makes in its reply brief to the defendants’ standing to have sought disqualification of H & G. Inasmuch as PGI did not make this challenge in its opening brief, it has waived this argument. See United States v. Pelullo, 399 F.3d 197, 222 (3d Cir.2005) (“It is well settled that an appellant’s failure to identify or argue an issue in his opening brief constitutes waiver of that issue on appeal.”).20
Turning to the merits of PGI’s petition with respect to the complete removal of H & G, even if the district court should have applied Pa. R.P.C. 1.9, as PGI submits, PGI nonetheless cannot demonstrate that it is entitled to mandamus relief. Rule 1.9 prohibits a lawyer from taking a position adverse to a former client in the same or a related matter unless the former client consents after consultation. Here, it has not been shown that its former clients, the Gutmans, consented to H & G representing PGI let alone consented after appropriate consultation as required by Rule 1.9. Rather, portions of the record suggest just the opposite — -both Alvin Gutman and James Gutman in deposition testimony expressly denied that consent was given since, in their view, there was no potential conflict. See J.A. at 1318, 1324.21 Moreover, inasmuch as we believe that the beneficiaries of the Plan have an interest in the Plan being represented separately [403]*403from an attorney aligned or even previously aligned with the Gutmans, we would not grant a writ of mandamus to require the district court to undo the disqualification of H & G even if the Gutmans had consented to H & G representing PGI.22
In closing we make some final comments with respect to the denial of the petition for a writ of mandamus. First, we point out that in denying the petition we are not affirming the district court’s orders. Rather, we are holding only that PGI’s claim for issuance of the writ is not “clear and indisputable,” and our holding is not intended to prejudice a later appeal, if there is one, after entry of final judgment. See In re Briscoe, 448 F.3d at 226. Second, our opinion should not be overread. We do not invite defendants in ERISA actions unjustifiably to bring third-party complaints in an attempt to manufacture circumstances justifying the appointment of a guardian ad litem for the plaintiff or the disqualification of the plaintiffs original counsel. We would expect that the district court would view such a third-party action with great caution and only in cases in which it is fully justified to do so will appoint a guardian ad litem for the plaintiff and remove its counsel.
V. CONCLUSION
For the foregoing reasons, we will dismiss the appeal for want of jurisdiction and deny the petition for a writ of mandamus.
