Before ANDERSON and BIRCH, Circuit Judges, and LAND *, District Judge.

BIRCH, Circuit Judge:

       This appeal requires us to determine the propriety of a district court order in

light of prior appeals and the scope to be afforded to broad arbitration clauses.

Based on our previous rulings and existing precedent, the district court refused to

compel arbitration of various claims asserted by plaintiffs-appellees and declined

to stay litigation of nonarbitrable claims. Because we previously affirmed the

district court’s refusal to compel arbitration of RICO conspiracy and aiding and

abetting claims in a decision not disturbed by the United States Supreme Court, the

law of the case doctrine compels us to affirm the district court’s order regarding



       *
         Honorable Clay D. Land, United States District Judge for the Middle District of
Georgia, sitting by designation.

                                               2
these claims. With respect to the scope to be given to broad arbitration clauses, a

matter not decided previously, we also affirm the district court’s ruling that broad

arbitration clauses cannot be extended to compel parties to arbitrate disputes they

have not agreed to arbitrate.

                                I. BACKGROUND

      Plaintiffs-appellees, a group of physicians acting on behalf of themselves

and others similarly situated (“physicians”), sued defendants-appellants, a

collection of health maintenance organizations (“HMOs”), on various

grounds—including violations of the Racketeer Influenced and Corrupt

Organizations Act (RICO), breaches of various state prompt pay statutes, and

claims for quantum meruit, breach of contract, and unjust enrichment. At bottom,

the physicians alleged that the HMOs, individually and collectively by conspiring

and aiding and abetting each other, failed to properly reimburse physicians for

services rendered. Because the facts of this case have been detailed in prior

opinions, see PacifiCare Health Sys., Inc. v. Book, 538 U.S. 401, 402-03, 123 S.

Ct. 1531, 1533-34 (2003); In Re Humana Inc. Managed Care Litig., 285 F.3d 971,

973 (11th Cir. 2002); In Re Managed Care Litig., 132 F. Supp. 2d 989, 992 (S.D.

Fla. 2000), we recount here only those facts relevant to this appeal.

      The physicians’ complaint alleged ten claims against HMOs: (1) conspiracy



                                          3
to commit RICO violations under 18 U.S.C. § 1962(d); (2) aiding and abetting

RICO violations under 18 U.S.C. § 2;1 (3) direct RICO violations under 18 U.S.C.

§§ 1962 (a) and (c); (4) RICO declaratory and injunctive relief under 18 U.S.C. §

1964(a); (5) breach of contract; (6) unjust enrichment; (7) violations of various

state prompt pay statutes; (8) violations of the California Business and Professional

Code; (9) violations of the Connecticut Unfair Trade Act; and (10) violations of the

New Jersey Consumer Fraud Act. In response, HMOs moved to compel arbitration

of these claims pursuant to arbitration agreements that had been signed between

some of the physicians and some of the HMOs. See In Re Humana Inc. Managed

Care Litig., 285 F.3d at 973 & n.1 (“[S]ome of the doctors had contracts with some

of the HMOs; some of those contracts had arbitration clauses.”). In deciding

which of physicians’ claims must be arbitrated, the district court made four rulings:

       First, the court held that claims between plaintiffs and defendants who
       are both signatories to contracts containing enforceable arbitration
       clauses must be arbitrated. Second, relying primarily on our opinion
       in Paladino v. Avnet Computer Technologies, Inc., 134 F.3d 1054
       (11th Cir. 1998), the court found that those arbitration clauses that
       exclude punitive damages are unenforceable in this suit because they
       preclude recovery of treble damages under RICO; therefore, an HMO
       may not compel arbitration of a RICO suit under such an arbitration
       clause. Third, the court determined that an HMO may not invoke its
       arbitration clause to compel arbitration of an aiding-and-abetting
       charge regarding a doctor’s contractual rights with a different HMO.


       1
         The claims of conspiracy to violate RICO and aiding and abetting RICO violations shall
be collectively referred to as “indirect RICO claims.”

                                               4
       Fourth, the court held that exceptions to the general rule that a non-
       party to a contract may not invoke the contract—exceptions we
       described in MS Dealer [Serv.] Corp. v. Franklin, 177 F.3d 942 (11th
       Cir. 1999)—do not apply in the present case; thus, an HMO that is not
       a signatory to a particular contract may not invoke that contract’s
       arbitration clause to compel arbitration.

In Re Humana Inc. Managed Care Litig., 285 F.3d at 973 (footnotes omitted). On

appeal, we “affirm[ed] in its entirety the district court’s order for the reasons set

forth in its comprehensive opinion found at 132 F. Supp. 2d 989 (S.D. Fla. 2000).”

Id. at 973-74.

       HMOs then appealed to the United States Supreme Court with respect to the

district court’s second finding, i.e. that HMOs could not compel arbitration of

RICO claims if the arbitration clauses excluded punitive damages awards because

such clauses were unenforceable.2 The Supreme Court reversed our decision and

held that whether punitive damages limitations in the arbitration clauses precluded

an award of treble damages, and whether such a finding would render the

arbitration agreements unenforceable, should be decided by an arbitrator in the

first instance. PacifiCare Health Sys., Inc., 538 U.S. at 407. As a result, we

remanded this case to the district court “for further proceedings in accordance with

the Supreme Court’s decision.” In Re Humana Inc. Managed Care Litig., 333 F.3d


       2
         At oral argument, HMOs admitted that they only sought certiorari with respect to this
issue and did not also appeal the district court’s other rulings, some of which they challenge in
this appeal.

                                                 5
1247, 1248 (11th Cir. 2003).

       While the issue of the arbitrability of RICO claims in light of contractual

punitive damages limitations was on appeal, the physicians amended their

complaint to add two new defendants, twelve new physician-plaintiffs, and six new

medical association plaintiffs. They also amended their complaint to clarify the

general allegations of conspiracy found in their prior amended complaint.3

Following our remand, HMOs again moved to compel arbitration based on the

Supreme Court’s PacifiCare opinion. The district court ruled that: (1) direct RICO

claims must be arbitrated pursuant to PacifiCare regardless of damages limitations

in the arbitration agreements; (2) indirect RICO claims remain nonarbitrable

pursuant to prior decisions which had not been disturbed by PacifiCare; (3)




       3
          The parties disagree about whether the physicians’ amended complaint really averred
anything new. HMOs admitted that the “amended complaint clarified plaintiffs’ theory of RICO
conspiracy and aiding-and-abetting liability.” Appellants’ Br. at 10-11 (emphasis added).
HMOs argue, however, that the general allegations of conspiracy found in physicians’ first
amended complaint did not subsume the more specific allegations of conspiracy found in the
second amended complaint, i.e. that because all HMOs were concertedly failing to reimburse
physicians properly, they conspired to effectively deny physicians the option to decline
rendering services for a particular HMO in favor of contracting with a competing HMO. See
Appellants’ Reply Br. at 21-22. The physicians disagree and point to similar language found in
both amended complaints with respect to HMOs’ conspiracy. See Appellee’s Br. at 19-20. The
district court agreed with the physicians. See In Re Managed Care Litig., __ F. Supp. 2d __, __
(S.D. Fla. Sept. 15, 2003) (“[T]he ‘new’ allegations differ more in degree than in kind.”); see
also Klay v. Humana, Inc., 382 F.3d 1241, 1241 n.1 (11th Cir. 2004) (“[T]he substance of the
allegations is the same across all three of the plaintiffs’ complaints.”).

                                               6
nonparticipating provider claims (“non-par claims”)4 are nonarbitrable if raised by

physicians in the absence of either (i) a contract between the physician and the

HMO regarding the services from which the claim arose or (ii) an assignment to a

physician of the claim by a subscriber who had a contract with the HMO; (4)

claims asserted by medical associations are arbitrable only to the extent that the

claims of their members, on whose behalf the medical associations are raising the

claims, are arbitrable; (5) the range of arbitrable claims is limited to those claims

which arose during the effective dates of the arbitration contracts; and (6) litigation

of nonarbitrable claims pending before the district court would not be stayed

pending arbitration of claims deemed arbitrable. See In Re Managed Care Litig.,

__ F. Supp. 2d __, __ (S.D. Fla. Sept. 15, 2003). On appeal, HMOs argue that the

district court erred by not directing arbitration of all indirect RICO claims, non-par

claims, medical association claims, and claims outside of the effective dates of

relevant contracts containing arbitration clauses and by not granting a stay of



       4
         These claims arise when a patient receives care from a physician who is outside of an
HMO’s network of preferred physicians. This means the physician does not have a contract with
the HMO to provide services for that particular patient. When a patient receives care from an
out-of-network physician, the physician can attempt to receive payment directly from the HMO
as a courtesy to the patient or the physician can receive a direct assignment of the patient’s
contractual right to reimbursement from the HMO. Because the treating physician does not
participate in the patient’s plan, such claims for reimbursement are referred to as “non-par”
claims. These claims become more complicated in this case because some doctors have both
contractual and non-par claims against some HMOs depending on the coverage of the patient
from whom the claim for reimbursement arose.

                                              7
litigation pending the resolution of arbitrable claims.

                                  II. DISCUSSION

      Because the issue of the arbitrability of indirect RICO claims was decided in

our prior opinion, we will address it first under law of the case principles. Second,

we will address the district court’s refusal to compel arbitration of certain non-par

claims, medical association claims, and claims outside the effective dates of

contracts. Third, we will review the district court’s denial of a motion to stay of

litigation of nonarbitrable claims.

A. Indirect RICO Claims and Law of the Case

      The law of the case doctrine “‘posits that when a court decides upon a rule

of law, that decision should continue to govern the same issues in subsequent

stages in the same case.’” Christianson v. Colt Indus. Operating Corp., 486 U.S.

800, 816, 108 S. Ct. 2166, 2177 (1988) (citation omitted). This doctrine is

designed to further important goals vital to just and efficient judicial process,

including the provision of an end to litigation, the discouragement of “panel

shopping,” and the promotion of consistency in rulings between courts. Burger

King Corp. v. Pilgrim’s Pride Corp., 15 F.3d 166, 169 (11th Cir. 1994). The

doctrine does not bar consideration of issues that could have been raised in a prior

appeal but were not; however, the doctrine does apply not only as to “matters



                                           8
‘decided explicitly’ but also as to those ‘decided by necessary implication.’”

DeLong Equip. Co. v. Washington Mills Electro Minerals Corp., 990 F.2d 1186,

1196 (11th Cir.) (citations omitted), modified on other grounds, 997 F.2d 1340

(11th Cir. 1993). The law of the case doctrine should guide a court in its discretion

to hear subsequent appeals on a particular issue. See Arizona v. California, 460

U.S. 605, 618, 103 S. Ct. 1382, 1391 (1983). The doctrine, however, does not

limit the court’s power to revisit previously decided issues when (1) new and

substantially different evidence emerges at a subsequent trial; (2) controlling

authority has been rendered that is contrary to the previous decision; or (3) the

earlier ruling was clearly erroneous and would work a manifest injustice if

implemented. Wheeler v. City of Pleasant Grove, 746 F.2d 1437, 1440 (11th Cir.

1984) (per curiam).

      With these standards in mind, we must determine whether our prior decision

constitutes law of the case as to indirect RICO claims and whether any of the

Wheeler exceptions apply. First, HMOs argue that the district court and our court

only decided that HMOs could not compel arbitration based on the contractual

rights of third parties. Accordingly, they contend that we did not reach the issue of

whether the indirect RICO claims actually did relate solely to the contractual rights

of third parties. HMOs maintain that, rather than relating to third party contractual



                                           9
rights, the indirect RICO claims touch matters within the parties’ arbitration

agreements and therefore are arbitrable. Second, HMOs argue alternatively that

even if the issue was previously reached, our prior opinion cannot be controlling

law of the case because the amendment of the complaint, the addition of new

defendants, and the decision in PacifiCare mandate we review our prior decision.

      HMOs’ first argument—that our previous decision did not reach the issue of

the arbitrability of indirect RICO claims—is without merit. A review of our

decision reveals that we affirmed two findings of the district court that bear on

indirect RICO claims: (1) “that an HMO may not invoke its arbitration clause to

compel arbitration of an aiding-and-abetting charge regarding a doctor’s

contractual rights with a different HMO . . . [and (2) that] an HMO that is not a

signatory to a particular contract may not invoke that contract’s arbitration clause

to compel arbitration.” In Re Humana Inc. Managed Care Litig., 285 F.3d at 973.

After making this determination, we affirmed the district court’s refusal to compel

arbitration of indirect RICO claims. Id. at 977. Necessarily implicit in that ruling

was a finding that indirect RICO claims did relate solely to third party contractual

rights. Moreover, we directly applied our decisions to the parties in several

examples which also implied this finding. See id. at 973 nn. 4-5. Realizing that a

prior decision is law of the case as to matters decided explicitly and by necessary



                                          10
implication, we find that our prior affirmation of the district court constitutes law

of the case here and forecloses HMOs’ argument that indirect RICO claims must

be arbitrated.5 See Burger King Corp., 15 F.3d at 169 (finding that prior decision

allowing recovery of attorney’s fees was law of the case by “necessary

implication” which foreclosed subsequent appeal that the case was not sufficiently

“exceptional” to award attorney’s fees under Lanham Act); Terrell v. Household

Goods Carriers’ Bureau, 494 F.2d 16, 19 (5th Cir. 1974) (finding that law of case

doctrine precluded review of causation issues where previous panel had affirmed

liability which necessarily implied a finding on causation).

       HMOs’ alternative arguments—that an exception to the law of the case

doctrine applies—are equally without merit. First, despite HMOs’ allegations to

the contrary, the district court found, and we agree, that physicians’ amended

complaint did not add anything new which would call into question our prior ruling

regarding indirect RICO claims. See supra n.3. A review of the first and second

amended complaints reveals that both contained the same basic allegations for the

conspiracy and aiding and abetting claims; moreover, HMOs admit that the second

       5
         We note that while the law of the case doctrine does not bind nonparties, our prior
decision does constitute precedent which we must follow in subsequent proceedings. See
Morrow v. Dillard, 580 F.2d 1284, 1289 (5th Cir. 1978) (stating that a court’s prior decision
“establishes a precedent” which the court “will, normally, apply to the same issues in subsequent
proceedings in the same case”). Thus, our prior decision regarding indirect RICO claims applies
to both parties and nonparties to the original decision, under law of the case principles as to the
former and under the rules of precedent as to the latter.

                                                11
amended complaint “clarified” physicians’ position rather than fundamentally

altering their claims. See id. Further, the addition of new parties did not

substantially change the nature of the indirect RICO allegations. Accordingly, we

reject HMOs’ argument that the law of the case should be abandoned because new

and substantially different evidence mandates a departure from the doctrine. See

Louisville & Nashville R.R. Co. v. Higdon, 234 U.S. 592, 598-99, 34 S. Ct. 948,

950 (1914) (affirming refusal to allow subsequent appeal under the law of the case

doctrine where an amended pleading “was simply an elaboration of the [pleading]

presented” in an earlier appeal); De Tenorio v. Lightsey, 589 F.2d 911, 917 (5th

Cir. 1979) (refusing to revisit prior findings because “plaintiff has presented

nothing new in her amended complaint”).6 Second, contrary to HMOs’ arguments,

PacifiCare did not affect our previous ruling regarding indirect RICO claims

because the Court only focused on whether remedial limitations in arbitration

clauses prevented arbitration of direct RICO claims; the scope to be afforded

arbitration agreements in the indirect RICO context was not before the Court. See

supra n.2. Therefore, the exception that the law of the case doctrine is inapplicable

       6
          In a separate brief, adopted by the other HMOs, PacifiCare argues that the amendments
to physicians’ complaint mandate we reconsider our decision that the MS Dealer exception,
which would allow an HMO that is a nonsignatory to an arbitration agreement with a physician
to invoke that agreement to compel arbitration of a physician’s claim against it, does not apply in
this case. Because we find that the amended complaint does not allege anything new, that
HMOs did not appeal our previous ruling on the MS Dealer issue, and that the Supreme Court’s
PacifiCare opinion did not affect our ruling, we reject PacifiCare’s argument.

                                                12
when controlling authority controverts a prior decision does not apply here. See

United States v. M.C.C. of Florida, Inc., 967 F.2d 1559, 1562 (11th Cir. 1992).

Because none of the three exceptions to the law of the case doctrine listed in

Wheeler apply, our prior decision regarding indirect RICO claims is controlling in

this appeal.

       While not an inexorable command, the law of the case doctrine provides

stability and finality in litigation, which are crucial cornerstone values for

developing a just and efficient judicial process. Litman v. Massachusetts Mut. Life

Ins. Co., 825 F.2d 1506, 1511 (11th Cir. 1987). Here, we previously decided, if

not explicitly then by necessary implication, that HMOs may not compel

arbitration of physicians’ indirect RICO claims. HMOs’ failure to seek en banc

review or certiorari with respect to these issues caused our previous ruling to

become law of the case. See Silverberg v. Paine, Webber, Jackson & Curtis, Inc.,

724 F.2d 1456, 1457 (11th Cir. 1983) (per curiam). Because HMOs have failed to

show that an exception mandates our departure from the law of the case doctrine,

we cannot reconsider our previous ruling.7 Accordingly, the district court properly

held that the law of the case doctrine precludes reconsideration of our previous



       7
         Absent an erroneous ruling that would work manifest injustice, consistency between
appellate panels is mandated even if a subsequent panel would have decided a case differently
than the prior panel. See United States v. Burns, 662 F.2d 1378,1384 (11th Cir. 1981).

                                               13
determination that HMOs cannot compel physicians to arbitrate their indirect

RICO claims.

B. District Court’s Refusal to Compel Arbitration

       We review a district court’s denial of a motion to compel arbitration de

novo. Musnik v. King Motor Co. of Fort Lauderdale, 325 F.3d 1255, 1257 (11th

Cir. 2003). The determination of the propriety of a motion to compel arbitration

pursuant to Section 4 of the Federal Arbitration Act (FAA) 8 is a two-step inquiry.

The first step is to determine whether the parties agreed to arbitrate the dispute.

Mitsubishi Motors Corp. v. Soler Chrysler-Plymouth, Inc., 473 U.S. 614, 626, 105

S. Ct. 3346, 3353 (1985). We must make this determination “by applying the

‘federal substantive law of arbitrability, applicable to any arbitration agreement

within the coverage of the [FAA].’”9 Id. (citation omitted). This inquiry must be

undertaken against the background of a “liberal federal policy favoring arbitration

agreements.” Moses H. Cone Mem’l Hosp. v. Mercury Constr. Corp., 460 U.S. 1,



       8
         9 U.S.C. § 4 (2004). The Act provides that “[a] party aggrieved by the alleged failure,
neglect, or refusal of another to arbitrate under a written agreement for arbitration may petition
any United States district court . . . for an order directing that such arbitration proceed in the
manner provided for in such agreement.” Id.
       9
         The FAA applies to any contract “affecting” interstate commerce. Allied-Bruce
Terminix Cos. v. Dobson, 513 U.S. 265, 273-74, 115 S. Ct. 834, 839 (1995); see 9 U.S.C. § 2
(FAA covers any “contract evidencing a transaction involving commerce”). It is undisputed that
the contracts at issue in this case affect interstate commerce and that the precedent construing the
FAA applies.

                                                 14
24, 103 S. Ct. 927, 941 (1983) (“[Q]uestions of arbitrability must be addressed

with a healthy regard for the federal policy favoring arbitration.”). Under this

policy, it is the role of courts to “rigorously enforce agreements to arbitrate.” Dean

Witter Reynolds, Inc. v. Byrd, 470 U.S. 213, 221, 105 S. Ct. 1238, 1242 (1985).

Because arbitration is a matter of contract, however, the FAA’s strong

proarbitration policy only applies to disputes that the parties have agreed to

arbitrate. Mastrobuono v. Shearson Lehman Hutton, Inc., 514 U.S. 52, 57, 115 S.

Ct. 1212, 1216 (1995). In the absence of an agreement to arbitrate, a court cannot

compel the parties to settle their dispute in an arbitral forum. See AT&T Techs.,

Inc. v. Communications Workers of Am., 475 U.S. 643, 648, 106 S. Ct. 1415, 1418

(1986) (citation omitted); see Volt Info. Sci., Inc. v. Bd. of Tr. of Leland Stanford

Junior Univ., 489 U.S. 468, 479, 109 S. Ct. 1248, 1256 (“Arbitration under the

[FAA] is a matter of consent, not coercion . . . .”). The second step in ruling on a

motion to compel arbitration involves deciding whether “legal constraints external

to the parties’ agreement foreclosed arbitration.” Mitsubishi Motors Corp., 473

U.S. at 628, 105 S. Ct. at 3355.10




       10
         Because the parties dispute only the scope of the arbitration agreements and not their
enforceability, we will not discuss this second step of the analysis.

                                               15
       1. Non-Par Claims

       With these general principles in mind, we turn to the district court’s ruling

that non-par claims are only arbitrable if: (1) the physician asserting the non-par

claim has a contract containing an arbitration clause with the target HMO that

covers the rendering of services from which the claim arose; or (2) the physician

was assigned a claim for reimbursement by a patient who has a contract with the

target HMO. First, HMOs argue that the broad arbitration clauses 11 signed by

physicians are sufficient to cover any non-par claims brought by physicians, even

if the contract they signed does not cover the rendition of services from which the

claim arose. Second, HMOs argue that all of physicians’ non-par claims, even

those the district court exempted from arbitration as claims held by the physicians

in their own right,12 are derivative of a patient-subscriber’s contract and therefore

arbitrable. We will address each argument in turn.

       First, HMOs’ attempt to expand the scope of various arbitration agreements


       11
          While the contracts signed between physicians (and patients) and HMOs vary in their
particular terms, they have in common the substance of broadly worded arbitration clauses. For
example, PacifiCare sought to compel arbitration based on a contract which called for arbitration
of “any controversy, dispute, or claim arising out of the agreement.” See In Re Managed Care
Litig., 132 F. Supp. 2d at 1005. Because we find that even the broadest arbitration clauses could
not compel arbitration of non-par claims in this instance, we need not parse through the language
used in each HMO’s arbitration agreements.
       12
          The district court held that physicians’ claims which arose under quasi-contractual
theories were not arbitrable because the claims belonged to the physicians in their own right and
not on the basis of an assignment.

                                               16
to cover the rendition of services outside of the services contemplated by a

particular contract is ineffectual. Because arbitration can only be compelled when

the subject of the dispute has been agreed to be settled by arbitration, having one

contract which contains a broad arbitration agreement does not necessarily mean

that arbitration can be compelled when the subject of the dispute arises from a

separate contract which does not have an arbitration clause. Seaboard Coast Line

R.R. Co. v. Trailer Train Co., 690 F.2d 1343, 1352 (11th Cir. 1982) (refusing to

compel arbitration based on broad arbitration clause found in a license contract

between the parties when the underlying claim was for breach of a separate lease

contract which did not contain an arbitration clause). While we acknowledge that

any doubts concerning the scope of arbitrable issues should be resolved in favor of

arbitration, see Moses H. Cone Mem’l Hosp., 460 U.S. at 24-25, 103 S. Ct. at 941,

no doubt has been cast upon whether physicians agreed to arbitrate non-par claims;

it is undisputed that physicians did not sign contracts containing arbitration clauses

for the provision of the services from which the non-par claims have sprung. In

effect, physicians are nonsignatories of arbitration agreements with respect to these

non-par claims and yet HMOs are attempting to compel arbitration as if they were

signatories. Implicit in our previous decision was a rejection of this argument. See

In Re Humana Inc. Managed Care Litig., 285 F.3d at 973 (finding that “an HMO



                                          17
that is not a signatory to a particular contract may not invoke that contract’s

arbitration clause to compel arbitration”). Moreover, HMOs drafted the arbitration

agreements signed by the physicians with whom they have contracts and

represented to physicians without contracts that they would be compensated for

providing out-of-network services. If HMOs wanted the benefit of arbitration for

disputes arising from non-par claims, they could have contracted with physicians

for it. See Mastrobuono, 514 U.S. at 62-63, 115 S. Ct. at 1219 (construing scope

of arbitration agreement against the party that initiated the contract). Arbitration is

at its core a matter of contract, and here it is clear that physicians did not agree to

arbitrate these non-par claims. See EEOC v. Waffle House, Inc., 534 U.S. 279,

294, 122 S. Ct. 754, 764 (2002). Accordingly, the district court properly refused to

compel arbitration of non-par claims asserted by physicians based on arbitration

agreements they had signed regarding the provision of services unrelated to the

non-par claims.

      HMOs’ second argument—that the district court should have compelled

arbitration of non-par claims asserted by physicians under quasi-contract and

statutory causes of action because these claims stemmed from claims assigned to

them by patient-subscribers who had signed arbitration agreements—fails on

similar grounds. Because physicians asserting non-par claims do not have a



                                            18
contractual relationship with the HMO, they can only be compelled to arbitrate

non-par claims to the extent that they received the right to reimbursement by

assignment from patient-subscribers who had signed arbitration agreements. See

DiMercurio v. Sphere Drake Ins. PLC, 202 F.3d 71, 81 (1st Cir. 2000). However,

as with the non-par claims for services rendered outside of the contractual

relationship established between physicians and HMOs, the non-par claims

asserted by physicians under quasi-contract and statutory theories necessarily stem

from services rendered outside of the contracts established between patient-

subscribers and HMOs.13 Because these claims are thus held by physicians

independent of the patient-subscriber contracts, HMOs may not argue that the

scope of the arbitration agreements in the patient-subscriber contracts should be

extended to compel arbitration. See American Bankers Ins. Co. of Fla. v. First

State Ins. Co., 891 F.2d 882, 885 (11th Cir. 1990) (per curiam) (finding unjust

enrichment claims existed independently of contractual claims). Thus, the district


       13
          If the services rendered were covered by the contract between patient-subscriber and
the HMO, then the physicians’ claims would be arbitrable under the district court’s order that
“any claims that necessarily rely upon subscriber contracts with arbitration clauses must be
arbitrated.” In Re Managed Care Litig., __ F. Supp. 2d at __. HMOs, however, have
represented that physicians will be reimbursed for supplying medically necessary treatments to
patient-subscribers even if such treatments are not covered by contract. Thus, because the
physicians’ non-par claims in this instance are not based on any contract to provide the particular
treatments, quasi-contract and statutory theories are the physicians’ only recourse to recover for
these services. See Flint v. ABB, Inc., 337 F.3d 1326, 1331 n.2 (11th Cir. 2003) (explaining that
quasi-contract claims are the only claims available in the absence of a specific contractual
obligation to perform services) cert. denied, __ U.S. __, 124 S. Ct. 1507 (2004).

                                                19
court properly found nonarbitrable non-par claims asserted by physicians under

quasi-contract and statutory causes of action in the absence of an assignment from

a patient-subscriber who had signed an arbitration agreement.

      2. Medical Association Claims

      HMOs also argue that the district court erred by refusing to compel

arbitration of the indirect RICO and non-par claims brought by medical association

plaintiffs on behalf of some of their members. Specifically, as they argued

regarding physicians’ attempt to litigate these claims, HMOs argue that these

claims brought by the medical associations are within the scope of the various

arbitration agreements signed by the associations’ members or their patient-

subscribers who have assigned reimbursement claims to their members. Because

associations suing in a representative capacity are bound by the same limitations

and obligations as their members, see Arizonans for Official English v. Arizona,

520 U.S. 43, 65-66, 117 S. Ct. 1055, 1068 (1997), our previous discussion

regarding the scope to be afforded to arbitration agreements with respect to these

claims is controlling. Accordingly, we reject HMOs’ arguments to the extent that

they are inconsistent with our previous determinations of the scope to be given to

arbitration agreements as they impact indirect RICO and non-par claims.




                                         20
       3. Claims Outside of the Effective Dates of the Arbitration Agreements

       HMOs also argue that the district court erred by refusing to compel

arbitration of disputes which arose outside of the effective dates of the contracts

containing arbitration agreements. Specifically, HMOs argue that our decision in

Belke v. Merrill Lynch, Pierce, Fenner & Smith, 693 F.2d 1023, 1028 (11th Cir.

1982) compels us to order arbitration even for claims which arose either before or

after the execution of arbitration agreements.14 We disagree. Our decision in

Armada Coal Exp., Inc. v. Interbulk, Ltd., 726 F.2d 1566, 1567-68 (11th Cir.

1984), in which we refused to compel arbitration of claims that arose after a

contract with a valid arbitration agreement had been breached, demonstrated that

Belke did not categorically command the arbitration of claims arising from

disputes outside of the effective dates of arbitration agreements. Moreover, the

Supreme Court has since found in the collective bargaining context that arbitration

cannot be mandated for a grievance which arose after the expiration of an

arbitration agreement even when the parties bargained for a “broad arbitration

provision.” Litton Fin. Printing Div. v. NLRB, 501 U.S. 190, 193-201, 111 S. Ct.

       14
           HMOs argue alternatively that the question of the temporal scope to be afforded to
arbitration agreements should be a matter decided by an arbitrator in the first instance. In
essence, both parties dispute whether they in fact agreed to arbitrate disputes which arose either
before or after the effective dates of the arbitration agreements. Because such questions of
arbitrability are “undeniably an issue for judicial determination,” we reject HMOs’ argument that
an arbitrator should decide the temporal scope issue. AT&T Techs., Inc., 475 U.S. at 649, 106 S.
Ct. at 1418.

                                               21
2215, 2219-2223 (1991); see District No. 1 - Marine Eng’rs Beneficial Ass’n v.

GFC Crane Consultants, Inc., 331 F.3d 1287, 1291 (11th Cir. 2003) (noting that

“grievance arbitration obligations end upon expiration of the CBA unless the

parties have agreed otherwise”). Because arbitration is strictly a matter of contract,

we cannot compel arbitration for disputes which arose during time periods in

which no effective contract requiring arbitration was governing the parties. See

Brandon, Jones, Sandall, Zeide, Kohn, Chalal & Musso, P.A. v. MedPartners, Inc.,

312 F.3d 1349, 1358 (11th Cir. 2002) (per curiam) (“[W]e will compel no

arbitration of issues that are outside an agreement to arbitrate.”). Accordingly, the

district court properly refused to compel arbitration of claims arising from disputes

which arose outside of the effective dates of arbitration agreements.

C. District Court’s Refusal to Grant a Stay

      We review a district court’s denial of a motion to stay litigation of

nonarbitrable claims under an abuse of discretion standard. See Moses H. Cone

Mem’l Hosp., 460 U.S. at 21 n.23, 103 S. Ct. at 939 n.23; Sam Reisfeld & Son

Import Co. v. S. A. Eteco, 530 F.2d 679, 681 (5th Cir. 1976). Pursuant to Section

3 of the FAA, a district court shall stay a pending suit “upon being satisfied that the

issue involved in such suit or proceeding is referable to arbitration” under a valid

arbitration agreement. 9 U.S.C. § 3. For arbitrable issues, the language of Section



                                          22
3 indicates that the stay is mandatory. See Shearson/Am. Express, Inc. v.

McMahon, 482 U.S. 220, 226, 107 S. Ct. 2332, 2337 (1987) (“[A] court must stay

its proceedings if it is satisfied that an issue before it is arbitrable . . . .”) (emphasis

added). When confronted with litigants advancing both arbitrable and

nonarbitrable claims, however, courts have discretion to stay nonarbitrable claims.

See Moses H. Cone Mem’l Hosp., 460 U.S. at 21 n.23, 103 S. Ct. at 939 n.23;

AgGrow Oils, L.L.C., v. Nat’l Union Fire Ins. Co. of Pittsburgh, 242 F.3d 777,

782-83 (8th Cir. 2001); Sam Reisfeld & Son Import Co., 530 F.2d at 681. In this

instance, courts generally refuse to stay proceedings of nonarbitrable claims when

it is feasible to proceed with the litigation. See Dean Witter Reynolds Inc., 470

U.S. at 225, 105 S. Ct. at 1245 (White, J., concurring) (noting that the “heavy

presumption should be that the arbitration and the lawsuit will each proceed in its

normal course”). Crucial to this determination is whether arbitrable claims

predominate or whether the outcome of the nonarbitrable claims will depend upon

the arbitrator’s decision. See Genesco, Inc. v. T. Kakiuchi & Co., Ltd., 815 F.2d

840, 856 (2d Cir. 1987).

       Here, the district court found that it would be feasible to compel arbitration

of arbitrable claims while allowing litigation of nonarbitrable claims. The district

court stated that its refusal to grant the stay would not result in duplicative



                                             23
proceedings and would not permit a decision in either proceeding to have

preclusive effect in the other. Moreover, the district court did not find that

physicians were predominately advancing arbitrable claims. In fact, at oral

argument, it was disputed whether any arbitrable claims remained before the

district court which physicians had not dismissed.15 Because it is well established

that a district court may order arbitration and refuse to stay nonarbitrable

proceedings, the district court was properly within its discretion to refuse HMOs’

motion to stay litigation of nonarbitrable claims. See Dean Witter Reynolds Inc.,

470 U.S. at 221, 105 S. Ct. at 1243 (stating that proper enforcement of FAA might

yield “piecemeal” litigation); Moses H. Cone Mem’l Hosp., 460 U.S. at 20, 105 S.

Ct. at 939 (finding that district court may order the parties to resolve “related

disputes in different forums”).

                                      III. CONCLUSION

       In this appeal involving both signatories and nonsignatories of broad

arbitration agreements, HMOs argued that the district court erred by refusing to

compel arbitration and stay litigation based on an expansive interpretation of the

arbitration agreements and the strong federal policy favoring arbitration. As we


       15
           To the extent that claims deemed arbitrable have not been dismissed, we affirm the
district court’s order that the litigation of arbitrable claims must be stayed and that arbitration of
these claims must be compelled. Shearson/Am. Express, Inc., 482 U.S. at 226, 107 S. Ct. at
2337.

                                                  24
have explained, however, the law of the case doctrine precluded us from revisiting

our previous rulings regarding indirect RICO claims and the federal policy

favoring arbitration could not compel us to order arbitration of disputes which the

parties had not agreed to arbitrate. Accordingly, the district court’s order is

AFFIRMED.
