Opinion for the Court filed by Senior Circuit Judge WILLIAMS.
Burlington Resources Inc. (which, with its predecessors-in-interest, we will call “Burlington”) is a producer of natural gas. Three years ago, in
Burlington Resources Oil & Gas Co. v. FERC (“Burlington
I”),
On remand, the Commission reaffirmed its orders, proposing a number of distinctions between the Burlington Settlements and the Omnibus Settlements.
Burlington Res. Oil & Gas. Co. (“Remand Order”),
Burlington’s alleged liability arose under § 601 of the NGPA, which for many years imposed maximum lawful price ceilings on first sales of natural gas. 15 U.S.C. § 3431 (1982) (amended effective 1993, as part of Congress’s repeal of the NGPA price ceilings). The statute allowed producers to charge above the maximum, however, to recoup the cost of any state “severance, production, or similar tax.” NGPA § 110(a), (c), 15 U.S.C. § 3320(a), (c) (1982) (repealed effective 1993). The Commission at first interpreted this provision to allow recoupment of the Kansas
ad valorem
property tax, though not certain other state taxes; in a 1988 decision we required the Commission to justify this difference in treatment.
Colorado Interstate Gas Co. v. FERC,
*245
In 1993 the Commission ruled that reimbursements for the Kansas tax could not be added to the maximum price, and it required first sellers of gas to refund some of the tax-related revenues they had collected.
Colorado Interstate Gas Co.,
To avoid litigation, the Commission encouraged Kansas gas producers to settle their refund disputes with pipelines. In 2000 and 2001 the Commission approved Omnibus Settlements for Northern and Panhandle, respectively, under which the settling producers paid only a portion of their refund liabilities, and the two pipelines waived any claim to further refunds.
Northern Natural Gas Co. (“Northern Omnibus”),
Burlington, however, refused to join these agreements. During the period of uncertainty between our remand in Colorado Interstate Gas and the Commission’s 1993 order requiring refunds, Burlington had entered into settlements of its contract disputes with the two pipelines. The settlements had focused primarily on the problems posed by “take-or-pay” purchase obligations that the pipelines had found extremely onerous in the market conditions of the mid-1980s, but included language seeming to dispose of all claims relating to the contracts in question. See Northern 1989 Settlement Agreement para. 5, at 3 (releasing the parties “from any and all liabilities, claims, and causes of action, whether at law or in equity, and whether now known and asserted or hereafter discovered, arising out of, or in conjunction with, or relating to [the] said Contracts”); accord Panhandle 1992 Settlement Agreement para. 7, at 2. After the Commission resolved the uncertainty and required refunds of the Kansas tax reimbursements, Burlington denied any ad va-lorem tax liability to the two pipelines, arguing that its earlier settlements had released it from such claims.

Before examining the Commission’s proffered distinction between the Burlington and the Omnibus settlements, we must consider the actual meaning of the Burlington Settlements. On remand the Commission noted correctly that the Burlington Settlements’ main purpose was to exchange immediate payments for a reduction in the pipelines’ future “take-or-pay” obligations. It proceeded to announce that
ad valorem
liabilities “could
not
be eliminated in any take-or-pay settlement,”
Remand Order,
But we held in
Burlington I
that “the contract language does not reasonably permit exclusion of any claim that relates to payments made under the contracts,” including “Northern’s and Panhandle’s refund claims against Burlington.”
Burlington I
required the Commission to explain why, if it considered the Burlington Settlements to be unlawful and unenforceable, it had approved the ostensibly similar Omnibus Settlements.
The Commission, however, appears too proud to accept such interpretive charity. It insists that “all such agreements” — including, it seems, the Omnibus Settlements — “are unlawful and unenforceable.”
Remand Order,
We find this line of argument no less baffling than we did in
Burlington I.
The Commission’s approval of the Omnibus Settlements betrayed no hint that the
*247
agreements might be unlawful. Rather, the Commission found the settlements a “reasonable compromise,” was “heartened by the parties’ success,” and “encourage[d] similar efforts to settle the
ad valorem
tax refund claims.”
Northern Omnibus,
A second, and more important, reason for our disbelief is that the Commission enjoys prosecutorial discretion only when it acts as a prosecutor, which it is not doing here. Both in approving the Omnibus Settlements and in denying effect to the Burlington Settlements, it acted as an adjudicator, determining the merits of a legal controversy among adverse parties. While the Commission had ordered the pipelines to initiate proceedings against the producers (through the filing of Statements of Refunds Due), the proceedings inevitably took the form of an adjudication, with adverse parties and competing claims of right. See, e.g.,
Panhandle Omnibus,
At most, the Commission may employ prosecutorial discretion in settling its
own
claims, by deciding “not to take additional enforcement actions” against private parties.
Remand Order,
But the Omnibus Settlements were not merely a “termination of Commission enforcement actions,”
Remand Order,
* * *
Without prosecutorial discretion to rely on, the Commission must — as we said last time — either “recog[nize] that ... the NGPA does not render unlawful all private agreements allowing a producer to retain funds collected pursuant to unlawfully high prices,”
Burlington I,
It is common ground that, by imposing a price ceiling on first sales of natural gas, the NGPA in a general sense invalidated any private agreement to pay more than the maximum lawful price. The Commission now reads this rule to prohibit any settlement agreement over past gas sales, even one reached in good faith and at arm’s length, that allows a party to retain past payments that might later be construed (based on a rather special idea of how consideration is assessed) to embody prices exceeding the statutory price ceiling. See
Northern Order,
Such a reading goes far beyond the precedents on which the Commission relies. Under the filed rate doctrine the Supreme Court applied in
Arkansas Louisiana Gas Co. v. Hall (“Arkla”),
Both Arkla and Southern Union, then, applied the same rule to prospective private agreements for the sale of gas: one cannot create a legal obligation, whether sounding in contract or in tort, to make a payment for future sales of more than the lawful price. Southern Union merely extended Arkla to contracts offering the parties a second means of recovery — through tort law. See generally Gregory Klass, Contracting for Cooperation in Recovery, 117 Yale L.J. 2 (2007). Whereas Arkla invalidated an agreement of the form, “I agree to pay more than the lawful price for gas,” Southern Union did the same for an agreement of the form, “I agree to pay more than the lawful price for gas, and you represent (negligently or not) that this gas is not within the scope of the price ceiling.” It would have driven a rather large hole in the interstate price ceiling regime if a contractually created alternative legal theory had allowed the recovery of a supra-lawful price.
Neither
Arkla
nor
Southern Union,
however, laid down any rule with respect to retrospective settlement agreements concerning past payments for gas. Al
*249
though the contract terms discussed in
Southern Union
were contained in a “settlement agreement,” the terms (insofar as they were relevant to our decision) addressed
future
sales, and they were located in such an agreement only as part of the consideration for a release of unrelated claims. See
Southern Union,
Because of its misinterpretation of
Southern Union,
the Commission reasoned that a settlement of past
ad valorem
tax disputes is invalid unless one can determine “precisely what consideration, if any, Burlington may have given for the specific purpose of satisfying its [Kansas
ad valorem
tax] refund obligations.”
Rehearing Order,
The Commission’s theory completely miscomprehends the nature of settlements negotiated under conditions of uncertainty. It is true that for each past overpayment, the maximum-price rule provides the purchaser with a right to a full refund. But the law does not prevent purchasers from later exchanging those accrued rights for other valuable consideration. Even in a settlement purporting to settle a single issue, the Commission cannot insist that the exchange match the parties’ exact obligations as ultimately determined; that would ignore the costs of formally resolving all uncertainties — costs that the Commission recognized when it spoke on remand of “the strong public policy that supports settling complex matters that thereby avoids the costs and burdens of litigation and mitigates administrative burdens.”
Remand Order,
Moreover, our decision in
Williams,
which FERC invokes, considered a completely different question. There the pipeline claimed that it was entitled to pass along to customers the sums it had paid to gas producers in settlement of disputes over take-or-pay claims and certain gas pricing matters. Under the applicable rules, a pipeline could pass on
all
of its lawful payments for gas, but only
some
of its take-or-pay buy-out expenses. The settlements in
Williams
did not differentiate between the two sources of the aggregate amounts, and the Commission ruled that, in the absence of such pinpointing, the pipeline could not use the 100% recovery mechanism applicable to payments for gas. Though finding “merit” in the pipeline’s argument that FERC’s distinction “ele-vatefd] the form of settlement payments over their substance,”
By contrast, while the NGPA presumably invalidated collusive settlements, there is no allegation that the Burlington Settlements were collusive in any way: Burlington and the pipelines appear to have negotiated in good faith and at arm’s length, with every incentive to enforce their legal rights and with no apparent detriments to third parties. The parties had constructive notice that the Commission would soon revisit its treatment of the ad valorem taxes, and they were in a state of genuine legal uncertainty as to whether those taxes could be recouped.
In essence, the Commission holds that parties in such straits are forbidden from settling their disputes. Yet we have held in
Panhandle Eastern Pipe Line Co. v. FERC,
[T]hat [the purchaser] would have fared better by fighting than by settling ... is not a sufficient basis upon which to conclude that approving the settlement would be unfair, unreasonable, or contrary to the public interest. Parties settle in order to avoid the risk that they might do worse by litigating, both because they might lose and because winning might come at a high cost; both parties to a settlement accept the risk that they might have done better by fighting. It is perverse, therefore, to reject a settlement because later developments make one party’s decision appear unwise. Rejecting a settlement upon such a flimsy ground only diminishes the incentive of future disputants to settle their cases.
Id. at 74.
Panhandle’s reasoning is equally applicable here. The pipelines would indeed have done better by preserving their claims, for (as it turned out) they were legally entitled to full ad valorem refunds. But the law does not prevent them from exchanging this entitlement for other goods.
Nor do the pipelines’ second thoughts render the Burlington Settlements “contested,” or their enforcement “coercive,” as compared to the “uncontested” Omnibus Settlements, see
Remand Order, 112
As before, in the absence of a “reasoned and consistent explanation” for rejecting Burlington’s defense,
Burlington I,
So ordered.
