QUESTIONS PRESENTED
Petitioners filed suit for refunds of federal income tax in connection with their investments in tax-shelter partnerships. Under the Tax Equity and Fiscal Respon sibility Act of 1982 (TEFRA), the proper tax treatment of partnership items is determined at the partnership level in a unified audit and judicial proceeding. TEFRA further provides that individual partner-level suits may not be brought for tax refunds "attributable to partner ship items." 26 U.S.C. 7422(h). The questions presented are as follows:
1. Whether the Court of Federal Claims correctly declined to entertain petitioners' refund action challeng ing the assessment of interest under now-repealed 26 U.S.C. 6621(c) (1988) for the partnerships' tax motivated transactions.
2. Whether the Court of Federal Claims correctly declined to entertain petitioners' refund action challeng ing the timeliness of the assessments of tax and interest attributable to partnership items.

FOR THE FEDERAL CIRCUIT
BRIEF FOR THE UNITED STATES IN OPPOSITION
OPINIONS BELOW
The opinion of the court of appeals (Pet. App. 1-17) is reported at 551 F.3d 1358. The opinion of the Court of Federal Claims (Pet. App. 18-50) is reported at 76 Fed. Cl. 455.
JURISDICTION
The judgment of the court of appeals was entered on January 8, 2009. A petition for rehearing was denied on March 18, 2009 (Pet. App. 163-164). The petition for a writ of certiorari was filed on June 16, 2009. The juris diction of this Court is invoked under 28 U.S.C. 1254(1).
STATEMENT
1. To achieve consistent tax treatment of all part ners in the same partnership and to remove the substantial administrative burden occasioned by duplicative audits and litigation, Congress enacted coordinated pro cedures for determining the proper treatment of "part nership items" at the partnership level in a single, uni fied audit and judicial proceeding. See Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA), Pub. L. No. 97-248, § 402(a), 96 Stat. 648; H.R. Conf. Rep. No. 760, 97th Cong., 2d Sess. 599-600 (1982). TEFRA defines the term "partnership item" as-
any item required to be taken into account for the partnership's taxable year under any provision of subtitle A to the extent regulations prescribed by the Secretary provide that, for purposes of this subtitle, such item is more appropriately determined at the partnership level than at the partner level.
26 U.S.C. 6231(a)(3). Regulations promulgated under Section 6231(a)'s grant of rulemaking authority provide that the term "partnership item" includes "the legal and factual determinations that underlie the determination of the amount, timing, and characterization of items of income, credit, gain, loss, deduction, etc." 26 C.F.R. 301.6231(a)(3)-1(b).
When the Internal Revenue Service (IRS) disagrees with a partnership's reporting of any partnership item, it must issue a Notice of Final Partnership Administra tive Adjustment (FPAA) before making against the partners any assessments attributable to that item. 26 U.S.C. 6223(a)(2) and (d)(2), 6225(a). If a petition contesting adjustments in an FPAA is filed, all partners with interests in the outcome are treated as parties (26 U.S.C. 6226(c) and (d)), and the court has jurisdic tion to determine all partnership items to which the FPAA relates (26 U.S.C. 6226(f)).
As part of TEFRA, Congress enacted the provision codified at 26 U.S.C. 7422(h). TEFRA § 402(c)(11), 96 Stat. 668. Section 7422(h), as relevant here, precludes any action for a tax refund "attributable to partnership items."1 The statutory scheme provides instead that tax treatment of any partnership item "shall be determined at the partnership level." 26 U.S.C. 6221. Accordingly, partners who intend to contest partnership items may do so only in the unified partnership proceeding, where the court "shall have jurisdiction to determine all part nership items of the partnership." 26 U.S.C. 6226(f).
2. a. Petitioners invested in limited partnerships promoted by AMCOR, a California corporation that "was in the business of promoting tax shelter partner ships" during the early to mid-1980s. Pet. App. 3. Peti tioners reported their distributive shares of partnership losses on their 1984 and 1985 individual income tax re turns and used those losses to offset their taxable in come in those years. Ibid. The IRS examined the part nerships' tax returns and issued an FPAA to each part nership in 1991. Ibid. The FPAAs disallowed the loss deductions reported by the partnerships in 1984 and 1985 and, accordingly, reduced those deductions to zero. Ibid. Each FPAA stated that the deductions were not allowable because, inter alia, "[t]he partnership's activi ties constitute a series of sham transactions." Ibid.
In response, certain partners filed petitions in the Tax Court for readjustment of partnership items pursu ant to 26 U.S.C. 6226. Pet. App. 3. In those petitions, the partners claimed that the period for assessing tax attributable to the adjusted partnership items had ex pired prior to issuance of the FPAAs and that the IRS had erred in determining that the partnerships' activi ties constituted a series of sham transactions. Ibid. Because petitioners were partners in the partnerships, they automatically became parties to the suit. See 26 U.S.C. 6226(c).
While the partnership proceedings were pending in the Tax Court, petitioners settled some of their dispu ted partnership items with the IRS. Pet. App. 4. In the settlement agreements, petitioners were permitted to report a portion of the previously disallowed deduc tions. Ibid. In return, petitioners agreed to waive the restrictions on the assessment and collection of any defi ciency attributable to partnership items and also agreed that they would not file any refund claim based on any change in the treatment of partnership items. Id. at 4, 36. Petitioners further agreed that the settlements "may result in an additional tax liability to [them] plus interest as provided by law." Id. at 4. The IRS subse quently assessed the additional tax and interest now at issue, including interest at the enhanced rate for sub stantial underpayment attributable to tax motivated transactions under now-repealed 26 U.S.C. 6621(c) (1988) (former Section 6621(c)).2
The Tax Court issued stipulated decisions in the partnership proceedings in 2001. Pet. App. 4 n.2. Those decisions stated that the adjustments to partnership in come and expense were attributable to transactions that lacked economic substance as described in former 26 U.S.C. 6621(c)(3)(A)(v) (1988). Pet. App. 4 n.2. The decisions also stated that the assessment of any deficien cies in income tax attributable to the adjustments to partnership items was not time barred by 26 U.S.C. 6229. Pet. App. 4 n.2.
Petitioners separately filed administrative refund claims with the IRS. Pet. App. 4. Petitioners asserted that their settlement agreements and the resulting as sessments had been made after the statute of limitations had expired, and, alternatively, that they were not liable for tax motivated interest under former Section 6621(c). Id. at 188-209. The IRS denied the claims. Id. at 4.
b. Petitioners commenced separate refund actions in the Court of Federal Claims, and the suits were consoli dated. Pet. App. 4. The government filed a motion for partial dismissal, arguing that 26 U.S.C. 7422(h), which prohibits actions for refunds "attributable to partner ship items," deprived the court of subject-matter juris diction.
The Court of Federal Claims granted the govern ment's motion. Pet. App. 18-50. The court held that, un der the TEFRA partnership rules, petitioners were not permitted to raise their limitations defense in a partner- level refund suit like this one. Id. at 26-41. The court explained that because petitioners' argument required a construction of 26 U.S.C. 6229(a), which extends the limitations period of 26 U.S.C. 6501(a) for assessing any tax attributable to partnership items, it involves a part nership item that may be raised only in the unified part nership proceeding. Pet. App. 27-28. In the alternative, the court held that petitioners had waived their limita tions defense in their settlement agreements. Id. at 32- 33. The court observed that a "legion of decisions" uni formly had concluded that because the limitations issue affects the partnership as a whole, it cannot be litigated in an individual partner proceeding. Id. at 34-35.
The Court of Federal Claims also held that petition ers were barred from challenging the assessment of tax- motivated interest in their partner-level refund suit. Pet. App. 48-49. The court explained that imposition of interest under former Section 6621(c) depended upon the nature of the partnerships' transactions, which itself presents a partnership item. Id. at 44-47. The court stated that where, as here, the interest was imposed because the partnerships had conducted sham transac tions, resolution of whether a transaction was a sham must occur in the partnership proceeding rather than in partner-level refund suits. Id. at 48-50. After the par ties stipulated to the dismissal of the remaining issues, the court entered final judgment. Id. at 4.
c. The court of appeals affirmed. Pet. App. 1-17. The court found that 26 U.S.C. 6231(a)(3), which defines the term "partnership item," did not unambiguously re solve whether petitioners' limitations claim was a part nership item. Pet. App. 9. The court accordingly gave deference, under the principles announced in Chevron U.S.A. Inc. v. NRDC, 467 U.S. 837, 843 (1984), to the agency interpretation of that provision reflected in 26 C.F.R. 301.6231(a)(3)-1(b). Pet. App. 9-10. The court concluded that petitioners' limitations claim was a part nership item because it was among the "legal and factual determinations that underlie the determination of the amount, timing, and characterization of items of income, credit, gain, loss, deduction, etc." of the partnership. Id. at 7 (quoting 26 C.F.R. 301.6231(a)(3)-1(b)); see id. at 9- 10. The court therefore held that Section 7422(h) barred the Court of Federal Claims from hearing petitioners' limitations claim in a partner-level refund suit. Id. at 11. The court explained that because the limitations claim affects the partnership as a whole, a contrary re sult would undermine TEFRA's goal of centralizing the treatment of partnership items and ensuring the equal treatment of partners. Id. at 10.
The court of appeals also held that the Court of Fed eral Claims lacked jurisdiction over petitioners' claims for a refund of tax motivated interest. Pet. App. 11-16. The court observed that the FPAAs had disallowed the partnerships' deductions based on, inter alia, the IRS's determination that the partnerships' transactions were shams. Id. at 12. The court noted as well that petition ers' settlement agreements with the IRS did not al ter that determination. Id. at 15-16. Former Section 6621(c), the court explained, expressly provided that a "sham" transaction was subject to tax motivated inter est. Id. at 12, 16. The court of appeals agreed with the Court of Federal Claims that the characterization of a partnership's transactions-including the determination whether a partnership transaction is a sham-is a part nership item. Id. at 14. Because petitioners' claim for refund of tax motivated interest was based on the asser tion that the partnerships' transactions were not shams, the court concluded, that claim was barred by Section 7422(h). Id. at 13-14.
ARGUMENT
1. Petitioners contend (Pet. 7-24) that, notwith standing 26 U.S.C. 7422(h), the Court of Federal Claims was authorized to consider their suit for refund of tax motivated interest assessed under 26 U.S.C. 6621(c) (1988). The court of appeals correctly rejected that ar gument. In any event, because former Section 6621(c) was repealed in 1989, the issue is of minimal prospective importance. Further review is therefore not warranted.
a. Former Section 6621(c) was added to the Internal Revenue Code in 1984 to discourage the proliferation of abusive tax shelters. See Deficit Reduction Act of 1984, Pub. L. No. 98-369, § 144(a), 98 Stat. 682; Staff of the Joint Comm. on Taxation, 98th Cong., 2d Sess., General Explanation of the Revenue Provisions of the Deficit Reduction Act of 1984, at 485-486 (1984).3 It increased the interest rate on substantial underpayments of tax attributable to "tax motivated transactions" to 120% of the otherwise applicable rate. Former Section 6621(c)(3)(A)(v) defined the term "tax motivated transac tion" to include "any sham or fraudulent transaction." A "substantial underpayment" was any underpayment exceeding $1000 per tax year.
Former Section 6621(c) was repealed by the Omnibus Budget Reconciliation Act of 1989 (OBRA), Pub. L. No. 101-239, § 7721(b), 103 Stat. 2399. It was one of sever al provisions for which OBRA substituted a single accuracy-related penalty. See § 7721(a), 103 Stat. 2399; H.R. Rep. No. 247, 101st Cong., 1st Sess. 1388-1394 (1989). The repeal was effective for tax returns due af ter December 31, 1989. See OBRA § 7721(d), 103 Stat. 2400.
b. The court of appeals correctly concluded that pe titioners were barred from challenging in this refund suit the assessment of tax motivated interest. Petition ers' suit is comfortably characterized as an action for a refund "attributable to partnership items" (26 U.S.C. 7422(h)). The interest became due because the IRS de termined that the partnerships' transactions were sham transactions and that the resulting underpayments of tax therefore were attributable to "tax motivated" trans actions (26 U.S.C. 6621(c)(3)(A) (1988)). To show that the assessment of such interest against them was im proper, petitioners would need to refute the determina tions, made at the partnership level in the FPAAs, that the transactions underlying their disallowed partnership deductions were shams.4
Section 7422(h) bars any such challenge in a re fund action.5 As the court of appeals explained (Pet. App. 13-14), the nature of a partnership's transactions- including the question whether they are tax motivated transactions for purposes of former Section 6621(c)-is a partnership item. See Nault v. United States, 517 F.3d 2, 8 (1st Cir. 2008); RJT Invs. X v. Commissioner, 491 F.3d 732, 737-738 (8th Cir. 2007); River City Ranch es #1 Ltd. v. Commissioner, 401 F.3d 1136, 1144 (9th Cir. 2005); Randell v. United States, 64 F.3d 101, 107- 108 (2d Cir. 1995), cert. denied, 519 U.S. 815 (1996). The nature of partnership transactions "underlie[s] the de termination of the amount, timing, and characterization of items of income, credit, gain, loss, deduction, etc." of the partnership, within the meaning of 26 C.F.R. 301.6231(a)(3)-1(b). And the nature of partnership transactions "is more appropriately determined at the partnership level," 26 U.S.C. 6231(a)(3), because it af fects the tax liability of all of the partners.
That tax motivated interest is not itself a partnership item (Pet. 10, 14-15) is beside the point. The dispositive question-as the statute expressly provides-is whether the interest at issue is "attributable to partnership items." 26 U.S.C. 7422(h) (emphasis added). Under peti tioners' interpretation of Section 7422(h), the provision would have virtually no application because tax, interest, and penalties-the only items for which any taxpayer can ever claim a refund-are not themselves partnership items.
Petitioners assert (Pet. 16) that the court of appeals' decision "denies [partners] any forum" to challenge the assessment of tax motivated interest. That is incorrect. In the very partnership proceedings in which petitioners were parties, the partners challenged the IRS determi nation in the FPAAs that the partnerships' transactions were shams. Pet. App. 3. Petitioners had notice of that issue, but they chose to settle their cases with the IRS and receive benefits under their settlement agreements (which allowed a portion of the deductions that the IRS originally had disallowed in full). Id. at 4, 49-50. The Tax Court ultimately decided the sham-transaction issue against the partners. Id. at 4 n.2. Section 7422(h) pre cludes petitioners' current effort to relitigate the issue in a refund action. Rather, TEFRA requires partners who intend to contest partnership-level issues to do so in the partnership-level proceeding. See pp. 2-3, supra.
c. Petitioners assert (Pet. 12-15) that the Court's in tervention is necessary to resolve a purported conflict among the courts of appeals. That argument lacks mer it. All the decisions cited by petitioners are readily dis tinguishable from the Federal Circuit's decision in this case.
Petitioners contend (Pet. 12) that the court of ap peals' ruling conflicts with the Fifth Circuit's decision in Weiner v. United States, 389 F.3d 152 (2004), cert. de nied, 544 U.S. 1050 (2005). As petitioners concede (Pet. 7), however, the Fifth Circuit in Weiner did not address the applicability of 26 U.S.C. 7422(h) to former Section 6621(c). Petitioners rely (Pet. 7, 11-13, 18-20) on Weiner to argue, on the merits, that tax motivated interest was improperly imposed against them because the FPAAs listed multiple grounds, which petitioners allege were "separable," for disallowance of the partnerships' deduc tions. See Weiner, 389 F.3d at 159-163. The Federal Circuit, while observing that it "would not be persuad ed" by that argument in any event, held as a threshold matter that the Court of Federal Claims lacked jurisdic tion to consider it. Pet. App. 16. Nothing in Weiner is inconsistent with that holding.
Petitioners also contend that the decision in this case conflicts with the Second Circuit's decision in Field v. United States, 328 F.3d 58 (2003). Although the court in Field held that the district court could consider the claim for refund of tax motivated interest in that case, the case did not address petitioners' particular claim, i.e., whether the court could make a partner-level deter mination regarding the nature of partnership transac tions. Rather, the taxpayers' refund claim in Field pre sented the distinct question whether tax motivated in terest constituted "interest" under 26 U.S.C. 6601 or was instead a penalty (as relevant for statute-of-limita tions purposes). See Field v. United States, 381 F.3d 109, 111 (2d Cir. 2004).
The Ninth Circuit's decision in Keller v. Commis sioner, 568 F.3d 710 (2009), is also distinguishable. Kel ler was a collection due process case, not a refund suit, and thus did not implicate Section 7422(h) at all. Fur ther, the court in the partnership proceeding in Keller had erroneously concluded that it lacked jurisdiction to determine whether the partnerships' transactions were tax motivated. Id. at 715. The Ninth Circuit held, under the unique circumstances of that case, that the Tax Court (which possessed jurisdiction under 26 U.S.C. 6330(c)(2)(B) to consider the taxpayers' liability if the taxpayers had received no prior opportunity to dispute it) could examine the partnership-level decision and evi dence as to whether the partnership transactions were tax motivated. Keller, 568 U.S. at 723. The Ninth Cir cuit emphasized, however, that "[i]n exercising this ju risdiction the Tax Court should not be making an inde pendent judgment at the partner level about whe ther partnership transactions were tax motivated." Ibid. The Court explained, as it had held in River City Ranches #1 Ltd., that the character of partnership transactions is a partnership item to be determined at the partnership level. Id. at 722.6
d. In any event, as noted above (p. 8, supra), former Section 6621(c) was repealed in 1989. See OBRA, § 7721(b), 103 Stat. 2399. The only transactions to which that repealed interest provision could apply were reported on tax returns due to be filed on or before De cember 31, 1989. See § 7721(d), 103 Stat. 2400. The statute does not apply to any new transactions. Al though petitioners' counsel has filed "many AMCOR related refund suits" (Pet. 20), and claims to "represent many more partners with similar refund claims" (ibid.), the universe of taxpayers potentially affected by former Section 6621(c) is necessarily finite and diminishing. Petitioners' conjecture that "likely there are thousands more § 6621(c) claims" (Pet. 21) strains credulity, as the statute was repealed 20 years ago.7 The issue raised in the petition therefore is one of limited and declining importance.
2. Petitioners also contend (Pet. 25-33) that the Court of Federal Claims should have entertained their limitations defense to the assessments in a partner-level refund suit. The court of appeals correctly rejected that argument, and its holding is consistent with the deci sions of all other court of appeals that have considered the question. The issue therefore does not warrant this Court's review.
a. After the completion of partnership proceedings, any income tax attributable to partnership items is as sessed at the partner level. See 26 U.S.C. 701. The IRS has the greater of the three-year period in 26 U.S.C. 6501 (which is based on the partner's individual return) or the three-year period in 26 U.S.C. 6229(a) (which is based on the partnership return) to make an assessment attributable to a partnership item. See AD Global Fund, LLC v. United States, 481 F.3d 1351, 1354 (Fed. Cir. 2007). The issuance of an FPAA suspends the stat ute of limitations during the time that a petition for re adjustment of partnership items may be filed, and for one year thereafter. 26 U.S.C. 6229(d).
b. The court of appeals correctly held that petition ers' refund claim that the assessments were made after the limitations period had expired is a partnership item and is therefore barred by Section 7422(h). Petitioners' limitations claim "is more appropriately determined at the partnership level," 26 U.S.C. 6231(a)(3), because it requires a construction of 26 U.S.C. 6229 and therefore affects the tax liability of all of the partners.8 The limi tations issue also "underlie[s] the determination of the amount, timing, and characterization of items of income, credit, gain, loss, deduction, etc." of the partnership, within the meaning of 26 C.F.R. 301.6231(a)(3)-1(b). As the court of appeals noted, petitioners "do not dispute that this regulation includes their limitations claim in its definition of 'partnership items.'" Pet. App. 8.
Contrary to petitioners' contention (Pet. 30-31), the court of appeals properly deferred to the agency's inter pretation of the term "partnership item." That regula tion was adopted pursuant to the congressional directive contained in 26 U.S.C. 6231(a)(3). When Congress au thorizes an agency to promulgate rules addressing a specific area of concern, regulations adopted under that authority "are given controlling weight unless they are arbitrary, capricious, or manifestly contrary to the stat ute." Chevron, 467 U.S. at 843-844.
Petitioners argue (Pet. 26) that under the court of appeals' decision, partners "have no court of competent jurisdiction in which to raise their limitations defense" for pre-1997 taxable years. That is incorrect. The limi tations defense was raised in the very partnership pro ceedings in which petitioners were parties, Pet. App. 3, but petitioners chose to settle their cases, id. at 4. Peti tioners' related contention (Pet. 25) that they were "barred by statute" from pursuing their limitations de fense in the partnership proceedings is similarly incor rect. See, e.g., Rhone-Poulenc Surfactants & Special ties, L.P. v. Commissioner, 114 T.C. 533, 535 (2000); C-99 Ltd. v. Commissioner, 66 T.C.M. (CCH) 1485, 1486-1488 (1993); Genesis Oil & Gas, Ltd. v. Commis sioner, 93 T.C. 562, 564 (1989). In any event, as peti tioners acknowledge (Pet. 25 n.26), a 1997 amendment expressly permits partners to participate in partnership proceedings solely for the purpose of asserting that the limitations period had expired. See Taxpayer Relief Act of 1997, Pub. L. No. 105-34, _ 1239(b), 111 Stat. 1027 (adding concluding clause to 26 U.S.C. 6226(d)(1)). Even if petitioners could demonstrate that the former statutory scheme raised significant due process con cerns, their constitutional claims are thus of little pro spective importance.
c. In any event, petitioners do not allege a conflict between the court of appeals' disposition of the limita tions issue and any decision of another court of appeals. To the contrary, the Federal Circuit's decision is in agreement with that of every other court of appeals to have considered the question. Four other courts of ap peals have held that the limitations defense that peti tioners sought to raise here is a partnership item that cannot be raised in a partner-level proceeding. See Weiner, 389 F.3d at 159; Davenport Recycling Assocs. v. Commissioner, 220 F.3d 1255, 1260 (11th Cir. 2000); Chimblo v. Commissioner, 177 F.3d 119, 125 (2d Cir. 1999), cert. denied, 528 U.S. 1154 (2000); Kaplan v. United States, 133 F.3d 469, 474 (7th Cir. 1998). Absent a conflict among the courts of appeals, this Court's re view is not warranted.
CONCLUSION
The petition for a writ of certiorari should be denied.

1 Section 7422(h) states:
No action may be brought for a refund attributable to partnership items (as defined in section 6231(a)(3)) except as provided in section 6228(b) or section 6230(c).
26 U.S.C. 7422(h). Petitioners do not contend that either specified ex ception applies here.
2 The court of appeals referred to former Section 6621(c) interest as "penalty interest," Pet. App. 4, but this brief hereinafter refers to it as "tax motivated interest."
3 Former Section 6621(c) originally was enacted as Section 6621(d). It was redesignated Section 6621(c) by the Tax Reform Act of 1986, Pub. L. No. 99-514, § 1511(a), 100 Stat. 2744.
4 FPAA determinations support the assessment of tax and interest against partners, unless those determinations are subsequently read justed by the Tax Court or altered by the terms of a settlement. See 26 U.S.C. 6225(a), 6226(a) and (f), 6229(d), 6231(b)(1)(C). The Tax Court did not readjust the FPAA sham-transaction determinations (and, in fact, later upheld them), and the settlements did not alter those determinations. Pet. App. 4.
5 The courts below viewed Section 7422(h) as a limitation on the subject-matter jurisdiction of the Court of Federal Claims, and petition ers do not dispute that characterization. Although Section 7422(h) does not use the term "jurisdiction," it implicates principles of sovereign im munity, cf. United States v. Dalm, 494 U.S. 596, 608-609 (1990), and it is properly read in conjunction with 26 U.S.C. 6226(f), which defines the scope of judicial review in partnership-level proceedings and does use the term "jurisdiction." In any event, because the government timely invoked Section 7422(h) as a ground for dismissal of petitioners' claims, the correct disposition of this case does not turn on whether Section 7422(h) is properly viewed as jurisdictional. Cf. Kontrick v. Ryan, 540 U.S. 443, 456 (2004) (noting that even non-jurisdictional rules may be "unalterable on a party's application").
6 Petitioners also suggest (Pet. 15) that the decision below conflicts with the Federal Circuit's prior decision in Prochorenko v. United States, 243 F.3d 1359 (2001). But unlike Prochorenko, which involved an issue "entirely dependent on [the partner's] own unique factual cir cumstances" (id. at 1363), this case involves issues that affect all part ners and are not dependent on facts unique to a particular partner (Pet. App. 14). In any event, any intra-circuit conflict would not warrant this Court's review. See Wisniewski v. United States, 353 U.S. 901, 902 (1957) (per curiam).
7 Petitioners note (Pet. 21) that cases arising out of the Hoyt tax- shelter partnerships also involved former Section 6621(c). The Ninth Circuit's decisions, however, have largely resolved those issues. See Keller, 568 F.3d at 710; River City Ranches v. Commissioner, 313 Fed. Appx. 935, 938 (9th Cir. 2009); River City Ranches #1 Ltd., 401 F.3d at 1136.
8 For example, adjudicating petitioners' limitations claim would re quire determinations as to whether the FPAAs were issued in time to suspend the limitations period, 26 U.S.C. 6229(d), and whether the "tax matters" partner had agreed to extend the limitations period, 26 U.S.C. 6229(b)(1)(B).
