GRABER, Circuit Judge.
In this case, the functions of our three branches of government intersect at a novel point. The United States District Court for the District of Montana issued Standing Order No. DWM-28 (“Standing Order”). The Standing Order directed the United States Attorney, within 20 days after sentencing occurs in each criminal case, to assemble and file with the court clerk a report of sentence. The court clerk was to send these reports to the United States Sentencing Commission, in order to satisfy a reporting requirement that Congress has imposed on the courts. We are asked to decide whether the district court exceeded its statutory or inherent authority, or the limits of the Constitution, by issuing the Standing Order.
Before reaching the merits of that question, however, we must consider our jurisdiction to answer it. The United States argues that we have jurisdiction to consider its direct appeal from the district court’s order denying its motion to set aside the Standing Order in this criminal case, which was one of the first cases in which the Standing Order’s requirements were triggered, even though neither party has appealed with respect to the underlying judgment of conviction. In the alter[983]*983native, if appellate jurisdiction is lacking, the United States petitions for a writ of mandamus.
These questions have divided our panel. Judge Clifton joins in Sections I, II, and III of Judge Graber’s opinion. Judge Brewster joins in Sections I, III, and IV of Judge Graber’s opinion. Thus, we are unanimous as to Sections I and III, while two judges agree on Sections II and IV. As a result, a majority of our panel concludes that the district court acted within the scope of its statutory and inherent authority when issuing the Standing Order and that the Standing Order did not violate the constitutional doctrine of separation of powers. The Standing Order thus remains in effect.
I. BACKGROUND
A. Reporting Requirements Under Federal Sentencing Law
In the Sentencing Reform Act of 1984, Congress created the federal Sentencing Commission as an independent body within the judicial branch. See Pub.L. No. 98-473, 98 Stat. 1837, tit. II, ch. II, § 217 (effective 1987). The Act also created a reporting requirement, which provided that”[t]he appropriate judge or officer shall submit to the Commission in connection with each sentence imposed ... a written report of the sentence.” Id. (first codified at 28 U.S.C. § 994(v), later redes-ignated as 28 U.S.C. § 994(w)).
A 1997 Memorandum of Understanding between the Administrative Office of the United States Courts and the Sentencing Commission, apparently intended to improve compliance with § 994(w)’s reporting requirement, provides insight into how the requirement generally was satisfied:
Most districts ask the probation office to submit the sentencing documents, and this is, as noted, generally being done faithfully. However, particularly where the probation office is not involved in the proceeding, the Chief Judge may want to meet with the United States Attorney’s office and others to decide on the most efficient way to submit [post-conviction] changes to the judgment.... These may be sent directly by other entities, or channeled through probation, as the court wishes.
The Memorandum of Understanding set forth the complete list of documents to be submitted as part of the sentencing report and “requested] that each Chief Judge designate a procedure by which the ... documents are sent to the Commission.”
On April 30, 2003, Congress amended § 994(w)’s reporting requirement. Prose-cutorial Remedies and Tools Against the Exploitation of Children Today Act of 2003 (sometimes called the “PROTECT Act”), Pub.L. No. 108-12, 117 Stat. 651, tit. IV, § 401(h) (“Improved Data Collection”).1 The text of the basic reporting requirement was amended to read, in part:
The Chief Judge of each district court shall ensure that, within 30 days following entry of judgment in every criminal case, the sentencing court submits to the Commission a written report of the sentence ....
[984]*98428 U.S.C. § 994(w)(l). The Act also codified the specific list of documents to be submitted in each report. Id. § 994(w)(l)(A)-(F).2
B. The District Court’s Standing Order and This Litigation
On May 9, 2003, “[i]n view of the new reporting requirements in the PROTECT Act of 2003,” the Chief Judge for the District of Montana issued the Standing Order at issue here. It contains four directives:
1.After sentencing in each case, the United States Attorney shall assemble a “Report of Sentence” that includes the following documents:
(a) a cover page setting forth the sentence, the offense or offenses for which it was imposed, the age, race, and sex of the offender, and all adjustments and departures actually applied in fashioning the sentence;
(b) a copy of the judgment and commitment order;
(c) a copy of the Court’s statement of reasons for the sentence imposed;
(d) a copy of any plea agreement;
(e) a copy of each ... charging document filed in the case ...; and
(f) a copy of the presentence report.
2. Within twenty days after sentencing in each case, the United States Attorney shall present to the Clerk of Court, Mis-soula Division, two copies of the cover page along with the remainder of the Report of Sentence.
3. The Clerk of Court shall mail the Report of Sentence to the Sentencing Commission.
4. In the event a Report of Sentence is not presented within twenty days after sentencing, the Clerk of Court shall report the deficiency to the attention of the Chief Judge.
Also on May 9, 2003, a judgment of conviction was entered in the criminal case of United States v. Victoria L. Ray, No. CR-02-0005-DWM, in the District of Montana. Rather than assemble and file a report of the sentence imposed in that case, pursuant to the Standing Order, the United States Attorney filed a Motion to Set Aside the Standing Order (or, in the alternative, to stay enforcement of the Standing Order pending appellate review).3
After a hearing before the District of Montana’s three active judges, the district [985]*985court denied the motion to set aside the Standing Order.4 In its order dated July 29, 2003 (“July 29 order”),- the court explained that, because the District of Montana consists of five dispersed divisions and has no “central hub,” the Standing Order was the most efficient way to comply with the statutory reporting requirement. The court held that the Standing Order did not conflict with the PROTECT Act, did not exceed the court’s authority, and did not violate the Constitution. On August 1, 2003, the United States appealed from the July 29 order and, alternatively, petitioned for a writ of mandamus.5
II. JURISDICTION
Although the United States and the district court agree that we have jurisdiction under 28 U.S.C. § 1291 to consider this appeal, Ray contends that we lack jurisdiction because the underlying criminal matter has been fully adjudicated and thus no case or controversy remains as between the government and Ray.6 This court has an independent obligation to determine its jurisdiction. United States v. Ceja-Prado, 333 F.3d 1046, 1049-50 (9th Cir.2003).
We have “jurisdiction of appeals from all final decisions of the district courts of the United States” in both civil and criminal matters. 28 U.S.C. § 1291. Thus, under § 1291 we must decide whether the district court’s July 29 order was a “final decision.” We also address Ray’s argument that the resolution of the underlying criminal matter makes this appeal moot.
A. The July 29 order was a “final decision. ”
. The Supreme Court has emphasized that the finality requirement is to be given “a ‘practical rather than a technical construction.’ ” Firestone Tire & Rubber Co. v. Risjord, 449 U.S. 368, 375, 101 S.Ct. 669, 66 L.Ed.2d 571 (1981) (quoting Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 546, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949)). Under modern doctrine, a “ ‘final decision’ generally is one which ends the litigation on the merits and leaves nothing for the court to do but execute the judgment. ... The foundation of this policy is not in merely technical conceptions of ‘finality.’ It is one against piecemeal litigation.” United States v. One 1986 Ford Pickup, 56 F.3d 1181, 1184 (9th Cir.1995) (per curiam) (quoting Catlin v. United States, 324 U.S. 229, 233-34, 65 S.Ct. 631, 89 L.Ed. 911 (1945)).
An order can be a “final decision” for purposes of § 1291 even if it is not the order terminating the primary litigation. Under the collateral order doctrine announced in Cohen, 337 U.S. at 546, 69 S.Ct. 1221, an order is “final” if it (1) [986]*986fully disposes of an issue before the court, (2) resolves an issue collateral to the underlying subject of the litigation, and (3) involves an important right otherwise irreparably lost if review had to await final judgment. See United States v. Poland (In re Derickson), 640 F.2d 946, 948 (9th Cir.1981) (per curiam); see also United States v. Friedman, 366 F.3d 975, 979 (9th Cir.2004) (listing Cohen factors). Furthermore, “when post-judgment orders are involved!,][t]he policy against and the probability of piecemeal review is not as decisive a consideration after judgment as before judgment since the underlying dispute is already settled.” United States v. Washington, 761 F.2d 1404, 1406 (9th Cir.1985). Indeed, “unless such orders are found final, there is often little prospect that further proceedings will occur to make them final.” Id.; see also Resolution Trust Corp. v. Ruggiero, 994 F.2d 1221, 1224 (7th Cir.1993) (“The final-decision rule (28 U.S.C. § 1291) postpones appeal to the final judgment — but what about orders issued after the final judgment? There is no problem when the postjudgment order concludes a discrete, collateral proceeding, such as a proceeding to award attorney’s fees for services rendered before the entry of the final judgment.”).
For these reasons, this court has found post-judgment orders to be “final” for purposes of § 1291 in a variety of criminal and civil contexts. Post-judgment orders involving attorney fees under the Criminal Justice Act of 1964 (“CJA”), 18 U.S.C. § 3006A, have been held to be “final” within the meaning of Cohen. United States v. Walton (In re Baker), 693 F.2d 925, 926 (9th Cir.1982) (per curiam); Derickson, 640 F.2d at 948.7 In Derickson, we noted:
The third Cohen factor!,] the involvement of an important right otherwise lost if review had to await final judgment!,] is, of course, inapplicable since Derickson submitted his fee request, following the usual procedure, after entry of final judgment in the underlying case.
640 F.2d at 948. Section 1291 also has supported jurisdiction for an appeal from a district court order directing the government to expunge all records of a 20-year-old criminal conviction from its files: “[T]o the extent that the district court’s order [987]*987constituted an injunction against the United States and its agencies, the order was a ‘final decision’ United States v. G, 774 F.2d 1392, 1393 (9th Cir.1985). Finally, although civil contempt orders entered during litigation cannot be appealed until final judgment is entered, post-judgment orders of civil contempt are appealable immediately under § 1291. See Hilao v. Estate of Marcos, 103 F.3d 762, 764 (9th Cir.1996) (holding that post-judgment orders of contempt are final and appealable under § 1291); Shuffler v. Heritage Bank, 720 F.2d 1141, 1145 (9th Cir.1983) (holding that the civil contempt order had “acquired all the elements of operativeness and consequence necessary to be possessed by any judicial order to enable it to have the status of a final decision under § 1291”) (internal quotation marks omitted); see also Sportmart, Inc. v. Wolverine World Wide, Inc., 601 F.2d 313, 316 (7th Cir.1979) (“[M]ost post-judgment orders are final decisions within the ambit of 28 U.S.C. § 1291 as long as the district court has completely disposed of the [underlying] matter.”).
Here, we conclude that the district court’s July 29 order refusing to set aside the Standing Order was a final decision, which is appealable under § 1291. As a post-judgment order, it does not implicate concerns about piecemeal review. The order was a final determination of the United States Attorney’s obligation to comply with the Standing Order in the present ease — an issue that is collateral to Ray’s prosecution, conviction, and eventual sen-fence. As we will discuss in Part IV, the Standing Order was incidental to the sentencing process. The United States Attorney’s appeal is therefore similar to appeals involving the question whether fees are to be paid to appointed counsel: Both appeals seek to vindicate rights of a party’s representative, rather than of the party itself, yet both issues are sufficiently connected to the underlying criminal case to be cognizable on appeal.8
B. This appeal is not moot.
Of course, we still would lack jurisdiction to consider this appeal if it did not satisfy the “case or controversy” requirement of Article III. See Foster v. Carson, 347 F.3d 742, 745 (9th Cir.2003) (“Mootness is a jurisdictional issue, and federal courts have no jurisdiction to hear a case that is moot, that is, where no actual or live controversy exists.” (internal quotation marks omitted)). Ray argues that the absence of a continuing controversy between herself and the government renders this appeal moot. We disagree.
We regard the United States Attorney’s appeal as similar to appeals involving litigation sanctions or sealing orders, in which an ongoing conflict between a district court and one remaining party is sufficient to establish a “case or controversy.” See, e.g., Riverhead Sav. Bank v. Nat’l Mortgage Equity Corp., 893 F.2d 1109, 1112 (9th Cir.1990) (holding that, although sanctions to be paid to another party were mooted by the parties’ settlement, sanc[988]*988tions to be paid to the court “are renewable on appeal regardless of whether the parties settle”); United States v. Vazquez, 145 F.3d 74, 83 (2d Cir.1998) (holding that a live controversy existed where the prevailing party remained subject to a sealing order).9 The continuing controversy between the United States Attorney and the district court, in which the United States Attorney alleges an injury capable of redress by this court, satisfies the “case or controversy” requirement of Article III.
III. STANDARDS OF REVIEW
We review de novo the district court’s resolution of legal issues, such as questions of statutory interpretation, United States v. Salemo, 81 F.3d 1453, 1457 (9th Cir.1996), and questions involving the court’s authority to act, United States v. Gatto, 763 F.2d 1040, 1044-45 (9th Cir.1985). We review for abuse of discretion the district court’s exercise of its authority. United States v. Doe, 125 F.3d 1249, 1253 (9th Cir.1997).
IV. MERITS
The United States contends that the Standing Order contravenes Congress’ intent, exceeds the district court’s authority, and violates the doctrines of separation of powers and sovereign immunity. In rejecting those arguments, we rely on three propositions: (1) that 28 U.S.C. § 994(w)(l) imposes a limited duty on the courts; (2) that this limited duty has become a part of the sentencing process in each criminal case; and (3) that the district court’s power to comply with that statutory duty by reasonable means, as well as to regulate the practice of litigants before it, authorized the court to issue the Standing Order.
By enacting § 994(w)(l), Congress imposed a duty on the district court to submit (not to draft, not to prepare, not to compile, not to write, not to originate, not to assemble) a sentencing report in connection with each federal criminal case. To fulfill its duty, the district court may employ all the powers it possesses, including both the powers impliedly granted by § 994(w)(l) and the court’s accustomed, inherent powers of case management. Those inherent powers include requiring a lawyer to prepare a document for the court’s use in connection with a specific case in which the lawyer represents one of the litigating parties. That is all the challenged Standing Order does.
Furthermore, by requiring the assistance of the United States Attorney in connection with a judicial proceeding to which the United States Attorney is a party, the Standing Order does not run afoul of the constitutional doctrine of separation of powers. The Constitution affords courts ample space to demand the assistance of an officer of the court in the context of litigation — even when that officer is also an officer of the executive branch. Indeed, we would create a separation-of-powers concern by interpreting § 994(w)(l) to have imposed a duty that is unrelated to the central mission of the judicial branch. By reading the statute as imposing a duty closely related to the sentencing process in each case — and therefore as constitutional — we follow the doc[989]*989trine of constitutional avoidance and, at the same time, confirm the district court’s authority to issue the Standing Order.
A. The Standing Order does not conflict with § 99k{w)(l).
The statute states that the “Chief Judge of each district court shall ensure that, within 30 days following entry of judgment in every criminal case, the sentencing court submits to the Commission a written report of the sentence.” 28 U.S.C. § 994(w)(l) (emphasis added). By its plain text, the statute imposes only two duties: first, that the district court “submit” a report in each criminal case; and, second, that the chief judge of each district “ensure” that the court submits the reports in a timely fashion. Neither the statute nor — -if we must resort to it — its legislative history10 suggests that Congress intended to require the district court to draft, prepare, compile, write, originate, or assemble the reports at all, or in any particular manner.11 Of course, a sentencing report that has not been prepared or compiled cannot be submitted; to that extent, Congress implicitly required that those prefatory tasks be done.12 But the statute contains no evidence that Congress [990]*990meant to dictate the manner in which they are accomplished. Congress was silent on those prefatory matters; its stated focus was on obtaining substantive information from the courts and on obtaining it promptly.
Neither does the statutory context suggest a congressional intent that district courts themselves prepare and compile the sentencing reports. The government notes that the PROTECT Act assigned separate reporting requirements to other entities (see supra note 1) and argues that, had Congress wanted United States Attorneys to prepare and compile the sentencing reports, it would have expressed that intent directly when detailing the United States Attorney’s new duties. Like so many canons of statutory construction, however, this principle (“expressio unius est exclusio alterius”) can be employed as easily to support the opposite interpretation. That is, had Congress cared how the sentencing court prepared or compiled the reports, Congress would have assigned those duties expressly to the court in the statute. It did not, nor did it implicitly signal a desire that courts themselves fulfill those tasks.13
Finally, the government can find little support in the principle that Congress ratifies an administrative interpretation of a statutory provision when it amends the statute without altering that provision. See Lindahl v. Office of Personnel Mgmt, 470 U.S. 768, 783 n. 15, 105 S.Ct. 1620, 84 L.Ed.2d 674 (1985) (“ ‘Congress is presumed to be aware of an administrative or judicial interpretation of a statute and to adopt that interpretation when it reenacts a statute without change ....’”) (quoting Lorillard v. Pons, 434 U.S. 575, 580, 98 S.Ct. 866, 55 L.Ed.2d 40 (1978)). The government argues that, by amending § 994(w) without addressing the method by which the sentencing reports were to be prepared or compiled, Congress expressed its intent that the reports be prepared and compiled as they had been in the past — by probation departments. (According to the 1997 Memorandum of Understanding, discussed above, the reports generally, although not exclusively, had been prepared by probation.departments.) Our colleague refines • this argument by suggesting, more generally, that Congress intended to “embody” the practice of having the reports assembled and compiled by one of the entities assigned to submit the reports. Op. of J. Clifton at 1002-1003. These arguments suffer from several difficulties.
Even assuming that the Sentencing Commission’s Memorandum of Understanding and Annual Reports, see op. of J. Clifton at 9823-24, alerted Congress to the existing administrative “interpretation” of [991]*991§ 994,14 the principle of ratification requires that there be a settled interpretation of which Congress could have been aware. Fogerty v. Fantasy, Inc., 510 U.S. 517, 531, 114 S.Ct. 1023, 127 L.Ed.2d 455 (1994). The Memorandum of Understanding and the Annual Reports demonstrate that the Sentencing Commission and the courts interpreted the statute to permit collaboration and flexibility in selection of the “appropriate judge or judicial officer” and in such officer’s compliance with the requirement. Every year from 1995 to 2001, the Annual Reports stated: “Pursuant to its authority under 28 U.S.C. §§ 994(w) and 995(a)(8), and after discussions with the Judicial Conference Committee on Criminal Law and the Administrative Office of the U.S. Courts (AO), the Commission requested that the probation office submit the following documents .15 (Emphasis added.) Yet the 1997 Memorandum of Understanding stated that “[mjost districts” used the help of the probation office and that “the Chief Judge may want to meet with the United States Attorney’s office and others to decide on the most efficient way to submit” the information, which “may be sent directly by other entities, or channeled through probation, as the court wishes. ”16 1997 Memorandum of Understanding (emphasis added). As the emphasized text shows, the 1997 Memorandum of Understanding gave the Chief Judge the authority “to decide on the most efficient way” and noted that the choice among options was to be “as the court wishes.” The Standing Order is consistent, then, with the administrative interpretation of the statutory text even if Congress intended to incorporate that interpretation.
Moreover, even Congress’ approval of a particular, settled manner of implementing the reporting requirement would not have prevented the implementing entities from altering their practice. See Am. Fed’n of Labor & Cong. of Indus. Orgs. v. Brock, 835 F.2d 912, 916 (D.C.Cir.1987) (“[T]he Supreme Court has stated that such legislative approval of an agency’s policy does not necessarily preclude the agency from subsequently changing that policy.... To freeze an agency interpretation, Congress must give a strong affirmative indication that it wishes the present interpretation to remain in place.”).
Here, not only did Congress give no affirmative indication that it wished to freeze the existing policy, it actually amended the statute to place greater emphasis on the responsibility of chief judges to ensure that the courts submit the sentencing reports. .
In short, nothing in the PROTECT Act prevented the district court from issuing the Standing Order. The next question to be addressed is whether § 994(w)(l), or some other source of the court’s power, affirmatively gave it the authority to issue the Standing Order.
B. The district court had authority to issue the Standing Order.
The district court’s authority to issue the Standing Order derives from two sources. First, viewing the statute in the light of general principles of statutory in[992]*992terpretation, we conclude that Congress’ imposition of the reporting requirement implies a corresponding grant of sufficient power to authorize the Standing Order. Second, viewing the statutory requirement as part of the sentencing process in each criminal case, we conclude that the district court’s inherent power to regulate the practice of litigants before it includes the authority to require a party to prepare and file documents like the sentencing reports.
1. By imposing a duty, § 99I(w)(l) impliedly granted district courts the power to take steps reasonably necessary to comply with the duty.
When Congress requires a governmental body to take a specified action, the statute implicitly includes the authority for the governmental body to accomplish that statutory directive in a reasonable manner. “Where a statute confers powers or duties in general terms, all powers and duties incidental and necessary to make such legislation effective are included by implication.” 2B Norman J. Singer, Statutes and Statutory Construction 388, § 55.04 (6th ed.2000). For example, we have held that the statutory duty of the United States Attorney to “prosecute for all offenses against the United States,” 28 U.S.C. § 547(1), implies the authority to make plea agreements incidental to prosecution. Thomas v. INS, 35 F.3d 1332, 1339 (9th Cir.1994). To similar effect, see United States v. Jones, 204 F.2d 745, 754 (7th Cir.1953) (“A general grant of power, unaccompanied by definite directions as to how the power is to be exercised, implies the right to employ means and methods necessary to comply with statutory requirements.”). The same principle has been applied in construing the scope of statutory authority given to executive-branch entities. See, e.g., In re Permian Basin Area Rate Cases, 390 U.S. 747, 776-77, 88 S.Ct. 1344, 20 L.Ed.2d 312 (1968) (noting that the width of administrative authority must be considered in the light of the purposes for which it is conferred and that Congress is presumed to give authority adequate to achieve those purposes with reasonable effectiveness).
We hold that, under the circumstances presented in this case, demanding the assistance of the litigating parties can be considered a reasonably necessary means for the chief judge to “ensure” that the sentencing courts promptly “submit” full and accurate sentencing reports. The special circumstances found in the District of Montana — with its three active judges sitting in five separate divisions — pose special challenges for complying with the reporting requirement. By altering the reporting requirement in 2003 to require each chief judge to “ensure” that the reports were submitted completely and on time, Congress suggested that chief judges are to have some flexibility in developing a system for submitting the reports — indeed, the Act’s text echoes the similar suggestion in the 1997 Memorandum of Understanding. As noted, that Memorandum expressly contemplated that a chief judge’s system for submitting the documents could include the participation, and even the direct submission of documents, by entities such as the United States Attorney’s Office.
In sum, § 994(w)(l) impliedly authorized the Standing Order.
2. The Standing Order also was permissible as a regulation of judicial proceedings.
The district court’s power to issue the Standing Order came not only from the authority implied by the statute, but also from the court’s inherent authority to regulate the practice of litigants before it.
[993]*993“Courts have (at least in the absence of legislation to the contrary) inherent power to provide themselves with appropriate instruments required for the performance of their duties.” In re Peterson, 253 U.S. 300, 312, 40 S.Ct. 543, 64 L.Ed. 919 (1920). The power acknowledged by the Court in Peterson has been described as the authority to take actions “necessary only in the practical sense of being useful.” Eash v. Riggins Trucking Inc., 757 F.2d 557, 563 (3d Cir.1985) (en banc). This inherent authority has been acknowledged explicitly by Congress in Federal Rule of Criminal Procedure 57(b), among other provisions. Rule 57(b) gives district courts power to “regulate practice in any manner consistent with federal law, these rules, ■ and the local rules of the district.” The advisory committee’s notes to Rule 57(b) contemplate that courts may exercise this authority by issuing standing orders of general application. Fed. R.Crim.P. 57(b), advisory committee’s notes (1995 amends.).17
The government argues that citation to the court’s case management authority is inapposite because the reporting requirement of § 994(w)(l) is not part of a judicial proceeding for the enforcement of rights. In the government’s view, the court’s power to regulate practice can encompass only those requirements that will assist the court in its core adjudicatory functions. Because the submission of sentencing reports is part of the court’s “monitoring” or “policymaking” function, the government contends, the delegation of the duty to compile those reports is not within the court’s power to regulate practice. We are not persuaded.
The reporting requirement is .reasonably incidental to the core judicial function of sentencing individual defendants and, therefore, is part of a judicial proceeding in which courts enjoy their usual power to regulate practice. Ordering the United States Attorney to compile the contents of sentencing reports falls within the court’s broad authority to regulate practice.
In regulating practice, courts commonly and permissibly compel assistance from litigants that is essentially clerical in nature and is'only loosely related to the court’s core adjudicatory functions. And district courts regularly demand this assistance in order to complete tasks that the courts themselves are required to accomplish. For example, district courts are required to make findings of fact in civil cases. FedlR.Civ.P. 52(a). Yet, we have recognized that district courts have the power to, and' commonly do, order a party to prepare the written statement of those findings. See, e.g., Stead Motors of Walnut Creek v. Auto. Machinists Lodge No. 1173, 886 F.2d 1200, 1204 n. 5 (9th Cir.1989) (en banc) (recognizing the “all too commonplace practice” of district judges to adopt findings prepared by the prevailing party); Indus. Bldg. Materials, Inc. v. Interchem. Corp., 437 F.2d 1336, 1339 (9th Cir.1970) (same). Indeed, some courts decide a case and then order the prevailing party to prepare and submit findings of fact. See 9A Charles Alan Wright & Arthur R. Miller, Federal Practice and Procedure 530, § 2578 (1995). Such written findings do not help the judge decide the facts, but are an after-the-fact administrative or ministerial chore [994]*994imposed on the party.18 Here, the United States Attorney represents the federal government, which is a party to each federal criminal proceeding.
Other administrative obligations that our own court imposes on the United States Attorney are even further removed from our core function of deciding a case. See, e.g., Ninth Circuit General Order 2.3(b) (requiring the United States Attorney to serve default orders on defendants); id. 12.8 (requiring the United States Attorney to deliver returned mail to prisoners). Furthermore, these obligations apply both before and after issuance of a disposition.
It is true that the Supreme Court has characterized the Sentencing Reform Act of 1984 as a delegation to the judicial branch of nonadjudicatory functions. Mistretta v. United States, 488 U.S. 361, 388-89, 109 S.Ct. 647, 102 L.Ed.2d 714 (1989).19 However, the Court went on to explain that the judiciary can be compelled to perform nonadjudicatory duties and functions, but only if they are closely related to the central mission of the judicial branch. Id. at 389, 109 S.Ct. 647. The Court gave several examples of duties and functions permissibly delegated to Article III courts that are “not necessarily or directly connected to adversarial proceedings in a trial or appellate court.” Id. at 389 n. 16, 109 S.Ct. 647. These functions included supervising grand juries, participating in the issuance of search warrants, and reviewing wiretap warrant applications. Id.
These examples show that a court retains its authority to manage the proceedings before it even when it is not engaged directly in adversarial or adjudicatory proceedings. For instance, we have acknowledged that, as part of their supervision of grand jury proceedings, district courts continue to possess the “inherent ability ... to formulate procedural rules not specifically required by the Constitution or Congress to supervise the administration of justice,” so long as those rules do not contravene or circumvent other federal statutes or rules. United States v. Larrazolo, 869 F.2d 1354, 1358 (9th Cir.1989), overruled on other grounds by Midland Asphalt Corp. v. United States, 489 U.S. 794, 799-800, 109 S.Ct. 1494, 103 L.Ed.2d 879 (1989); see also United States v. Armstrong, 781 F.2d 700, 703 (9th Cir.1986) (“When a grand jury witness refuses to testify, civil contempt sanctions can be imposed to coerce compliance with the court’s order, and penalties for criminal contempt can be assessed to punish the witness’ disobedient conduct.”).
In a sense, Congress grafted the requirements of § 994(w)(l) onto the sentencing phase of each criminal proceeding in district court. When judges are assigned tasks falling outside the precise limits of their adjudicatory functions, they are not — and should not be — stripped of their power to manage the proceedings, at [995]*995least when the assigned task is one closely connected to each judicial proceeding. The district court’s Standing Order was a permissible method of managing this aspect of the criminal proceedings before it.
Contrary to the government’s arguments, it does not follow from our conclusion that there is no limit to what a district court can require of a litigant in connection with a particular case. Section 994(w)(l) itself provides the limit to the authority we recognize here. That is, a district court can compel the assistance of litigants to complete tasks the court is required to complete in connection with a judicial proceeding. Because Congress chose to attach the reporting requirement to the conclusion of each criminal proceeding, the reporting requirement falls within the district court’s authority to manage those proceedings and does not implicate the separation-of-powers doctrine. Indeed, interpreting the reporting requirement in this way allows us to avoid another constitutional concern.
C. The Standing Order does not violate the Constitution.
The government contends that the Standing Order violates the separation-of-powers doctrine because, by “commandeering” the assistance of United States Attorneys, it “interfere^] impermissibly with the [executive branch’s] performance of its constitutionally assigned function,” INS v. Chadha, 462 U.S. 919, 963, 103 S.Ct. 2764, 77 L.Ed.2d 317 (1983) (Powell, J., concurring in the judgment), and blurs accountability for responsibilities assigned to the courts.20
The Supreme Court has recognized the separation of powers as a crucial, but somewhat flexible, requirement:
[W]hile our Constitution mandates that “each of the three general departments of government [must remain] entirely free from the control or coercive influence, direct or indirect, of either of the others,” the Framers did not require— and indeed rejected — the notion that the three Branches must be entirely separate and distinct.
Mistretta, 488 U.S. at 380, 109 S.Ct. 647 (quoting Humphrey’s Ex’r v. United States, 295 U.S. 602, 629, 55 S.Ct. 869, 79 L.Ed. 1611 (1935)). Because “our constitutional system imposes upon the Branches a degree of overlapping responsibility, a duty of interdependence as well as independence,” id. at 381, 109 S.Ct. 647, the commingling of functions among branches has concerned the Court only when commingling poses the danger of “encroachment” (that is, when it threatens to “undermine the authority and independence of one or another coordinate branch,” id. at 382, 109 S.Ct. 647) or “aggrandizement” (as occurs when one branch seeks “powers more appropriately diffused among separate Branches,” id.). Here, the government contends that the Standing Order encroaches on its authority and independence. We therefore must consider whether the Standing Order so disrupts the proper balance that it prevents the executive branch from fulfilling its constitutional [996]*996duties. United States ex rel. Kelly v. Boeing Co., 9 F.3d 743, 751 (9th Cir.1993). We conclude that it does not.
First, we interpret § 994(w)(1) and the Standing Order to impose duties closely connected to the sentencing process in each criminal case. This interpretation obviates the government's separation of powers concerns. That is, a court does not violate separation-of-powers principles by compelling the assistance of the United States Attorney, an officer of the court, in a judicial proceeding to which the United States is a party. The United States Attorney has responsibilities as a member of the executive branch, but also has duties as an officer of the court. See United States v. Hilario, 218 F.3d 19, 27 (1st Cir.2000) ("[W]hile United States Attorneys are admittedly part of the Executive Branch, they also are officers of the court who serve the Judicial Branch."); see also Newman v. United States, 382 F.2d 479, 481 (D.C.Cir.1967) ("An attorney for the United States, as any other attorney, however, appears in a dual role."). Fulfilling the latter duties does not impair the government's ability to accomplish the former.
Second, as a factual matter, we see no sign that complying with the Standing Order will impair the executive branch's ability to fulfill its constitutional duties. As we discussed above, the obligation is similar in nature to many already imposed on the United States Attorney in connection with litigation. And, as we will discuss below, the administrative burdens of complying with the Standing Order, on the record before us, appear to be minimal.
One final consideration supports our conclusion. By interpreting § 994(w)(1) as a requirement closely connected to sentencing, and thereby rejecting the government's argument that the Standing Order violates the separation of powers, we fulfill our duty to avoid an unconstitutional interpretation of an ambiguous statute if another plausible reading is constitutional. See INS v. St. Cyr, 533 U.S. 289, 299-300, 121 S.Ct. 2271, 150 L.Ed.2d 347 (2001). Were we to hold that compliance with § 994(w)(1)'s reporting requirement was so unconnected to the core functions of the judiciary that the court could not exercise its usual authority to compel the assistance of a litigating party in a judicial proceeding, the question would arise whether the reporting requirement itself was sufficiently connected to the "central mission of the Judiciary," Mistretta, 488 U.S. at 388, 109 S.Ct. 647, to survive a separation-of-powers challenge. This separation-of-powers issue logically precedes the question raised by the government: whether the court's delegation of these functions back to the United States Attorney, who represents a litigant in every federal criminal case, is constitutionally permissible.
In sum, § 944(w)(1) may be read to impose a task that is closely related to the central mission of the judicial branch-that is, record-keeping in connection with each individual federal criminal case. If we read the statute in that manner, it is constitutional, and the district court may employ its usual powers to accomplish this case-related task without running afoul of the separation of powers. If we were to read the statute to impose a task that is not related closely to the central mission of the judicial branch, it may well be unconstitutional, Mistretta, 488 U.S. at 389, 109 S.Ct. 647, and we therefore read the statute-assuming it is ambiguous-to avoid the problem.
D. The district court did not abuse its discretion.
In addition to the arguments concerning the court's authority to issue the Standing Order, the government makes [997]*997one additional argument: that the Standing Order is an abuse of discretion because it is unduly burdensome. The government points out that there were about 600 criminal cases in the District of Montana in 2003 and that the compilation of sentencing reports consumed the equivalent of one-third of the time of one full-time employee in that District’s probation department. The government also expresses concern that the court’s statement of reasons theoretically may not be received within the 20-day deadline imposed by the Standing Order, although the record contains no evidence that in any particular case such a delay actually occurred or could be expected to occur.
These concerns do not convince us that the Standing Order is an abuse of discretion. The burdens on the government in the District of Montana are not so great as to make the Standing Order an abuse of discretion, and the concern that the district court’s own timing will make the United States Attorney’s task impossible is, at this time, only hypothetical.
For the foregoing reasons, we hold that the Standing Order represents a valid exercise of the district court’s authority and we therefore AFFIRM the district court’s order denying the government’s Motion to Set Aside the Standing Order.
