executive branch officials remain accountable to the President, and ultimately the public, for their actions.35 
Limitations Imposed by the Appointments Clause 
The Appointments Clause imposes significant limitations on the structural choices that Congress may make in determining how executive agency officials are appointed.36 Under the Clause, principal officers must be appointed by the President, “with the Advice and Consent of the Senate,” while Congress may vest the appointment of “inferior Officers” “in the President alone, in the Courts of Law, or in the Heads of Departments.”37 Non-officers—that is, “mere employees”—are not subject to any constitutionally required method of appointment.38 
The breadth of authority that an executive branch official exercises typically determines the official’s classification as either an officer or non-officer for Appointments Clause purposes.39 Generally, if an executive official holds a “continuing position established by law” and “exercis[es] significant authority pursuant to the laws of the United States,” he is an “Officer of the United States.”40 The applicable standard for distinguishing between principal officers—who must be appointed with the advice and consent of the Senate—and inferior officers—whose                                                  32 See infra note 67. 33 See, e.g., 42 U.S.C. §executive branch officials remain accountable to the President38 and, likewise, that the President is responsible for the actions of those executive branch officials whose conduct he is able to control.39 Ultimately, these lines of intrabranch accountability and concomitant presidential responsibility aim to ensure that the Executive remains accountable to the public at large.40 
Limitations Imposed by the Appointments Clause The Appointments Clause limits Congress’s ability to specify in law how appointments are made for certain positions.41 The Clause distinguishes between the appointment of two classes of officers—what the Supreme Court’s case law refers to as “principal officers” and what the Clause itself refers to as “inferior Officers.” Principal officers must be appointed by the President, “by and with the Advice and Consent of the Senate.” Congress may employ this same appointment framework for inferior officers, but the Clause alternatively allows Congress to vest the appointment of such officers “in the President alone, in the Courts of Law, or in the Heads of

The breadth of authority that an executive branch official exercises typically determines the official’s classification as either an officer or non-officer for Appointments Clause purposes.43 Generally, if an executive branch official holds a “continuing position established by law” and “exercis[es] significant authority pursuant to the laws of the United States,” that person is an “Officer of the United States.”44 The standard for distinguishing between principal officers—who must be appointed with the advice and consent of the Senate—and inferior officers—whose appointment Congress may vest elsewhere—is arguably less clear.45 At times, the Supreme Court  At times, the Supreme Court

Limitations Imposed by Principles of Presidential Control  
The President’s general authority to supervise and oversee the executive branch also limits the structural choices Congress may make in designing agencies. These limits are often implicated by statutory provisions that seek to insulate an agency from presidential control by providing agency leaders with removal protections. For example, “for cause” removal protections generally prevent the President from removing an identified official except in cases of “inefficiency, neglect of duty, or malfeasance in office.”47 Generally, these and other removal provisions cannot be used to deprive the President of his constitutional duty to “oversee the faithfulness of the officers who execute” the law.48

45 U.S. CONST. art. II, § 2, cl. 2. Congress’s discretion to vest the appointment of an inferior executive branch official in the courts is not unlimited. For example, in Morrison v. Olson, the Court stated that such “interbranch appointments” may be improper if the judicial appointment “had the potential to impair the constitutional functions assigned to one of the branches,” or “if there was some ‘incongruity’ between the functions normally performed by the courts and the performance of their duty to appoint.” 487 U.S. at 676.  46 Buckley v.

For example, “for cause” removal protections generally prevent the President from removing a particular official except in cases of “inefficiency, neglect of duty, inefficiency, neglect of duty, 
or malfeasance in office.”52 Generally, removal provisions cannot be used to deprive the President of his constitutional duty to “oversee the faithfulness of the officers who execute” the law.53

Public 
Company Accounting Oversight Board (PCAOB),57 the Court invalidated statutory provisions providing that members of the PCAOB could be removed only for cause by the Securities and Exchange Commission, whose members were, in turn, also protected from removal by for cause removal protections.58 By insulating PCAOB members from presidential control with dual layers of for cause removal protections, the law had “impaired” the President’s necessary authority to “hold[] his subordinates accountable for their conduct” and “subvert[ed] the President’s ability to

In its most recent removal cases, the Court has invalidated removal provisions for certain officers engaged in financial regulation. In Free Enterprise Fund v.

These removal cases impose significant, if somewhat undefined, limitations on Congress’s authority to structure an agency to insulate certain officials from presidential control.66 For example, the Court has suggested that there are certain “purely executive” officials,67 and these persons “must be removable by the President at will if he is to be able to accomplish his constitutional role.”68 For this reason it is likely that congressional attempts to provide a traditional Cabinet official with “for cause” removal protections would be viewed as placing an impermissible obstruction on the President’s ability to carry out his executive functions.69 In any

governmental power in the hands of a single individual” who, because of his removal protection, is “accountable to no one.”72 
The Court’s most recent case on removal protections, Collins v. Yellen,73 further developed the law regarding removal protections for single-director agencies. The Court wrote that a “straightforward application” of the “reasoning in Seila Law” dictated its holding that Congress exceeded its authority by providing removal protections to the director of the Federal Housing  of the Federal Housing 
Finance Agency (FHFA).74 The Court rejected the view that a removal protection was permissible in the FHFA context because that agency allegedly had more limited regulatory powers than did the CFPB, the agency at issue in Seila Law. “Courts are not well-suited to weigh the relative importance of the regulatory and enforcement authority of disparate agencies.”75 Thus, the Court explained, “the constitutionality of removal restrictions” does not hinge “on such an inquiry.”76 
These removal cases impose significant, if somewhat undefined, limits on Congress’s authority to insulate certain officials from presidential control.77 For example, the Court has suggested that there are certain “purely executive” officials,78 and these persons “must be removable by the President at will if he is to be able to accomplish his constitutional role.”79 For this reason, the Court might conclude that legislation insulating the head of a department or agency from removal impermissibly obstructs the President’s ability to carry out his executive functions.80 On the other hand, the Court has upheld limits on the President’s ability to remove from office (1) the members of a multi-member board that is balanced along partisan lines and tasked with only “quasi-legislative” or “quasi-judicial” functions and (2) inferior officers with limited duties and “no policymaking or administrative authority.”81 In any event, providing certain officials with removal protections remains a useful tool for encouraging independence from the President and, possibly, greater responsiveness to Congress.82

The U.S. Court of Appeals for the Fifth Circuit had held that the structure of the FHFA was constitutionally invalid. See Collins v. Mnuchin, 938 F.3d 553, 587-88 (5th Cir. 2019) (en banc).

This doctrine is based in the separation of powers and works to prevent Congress from abdicating the core legislative function assigned to it by Article I of the Constitution.7991 Mistretta v. United States, 488 U.S. 361, 371 (1989) (“The nondelegation doctrine is rooted in the principle of separation of powers that underlies our tripartite system of Government.”); Panama Refining Co., 293 U.S. at 421 (“The Congress manifestly is not permitted to abdicate, or to transfer to others, the essential legislative functions with which it is” vested).

 There have, however, been recent developments in non-delegation doctrine jurisprudence. In Association of American Railroads v. Department of 
Transportation, for example, the U.S. Court of Appeals for the D.C. Circuit invalidated a delegation not on the grounds that Congress had failed to provide the agency with an intelligible principle, but because Congress violates due process when it provides a “self-interested entity with regulatory authority over its competitors.” 896 F.3d 539, 553 (D.C. Cir. 2018).

Finally, and perhaps most significantly, Congress exercises virtually plenary control over agency funding.114 This power to determine agency appropriations can be used to control agency priorities, prohibit agency action by 126 Cincinnati Soap Co. v. United States, 301 U.S. 308, 321 (1937) (“[N]o money can be paid out of the Treasury unless it has been appropriated by an act of Congress.”).  127 Budget authority “is an agency’s power provided by Federal law to incur financial obligations that will result in immediate or future outlays of government funds.” Maine Cmty.

resources by putting resources by putting

For example, a limitation might state that none of the funds contained in an appropriation are available for certain programs, including programs that the agency would be able to administer absent the funding limitation. Congress has used such appropriations act limitations to constrain agency action on issues ranging from the enforcement of federal

The Appointments Clause and the Treaty Clause respectively authorize the President to make certain appointments to important governmental positions and to finalize treaties with foreign nations or international bodies on behalf of the United States only after receiving the “advice and consent” of the Senate.229 “Advice and consent” in both contexts has been understood in practice to require senatorial approval, but not necessarily consultation.230

241 The advice-and-consent requirements of the Treaty Clause are not constitutionally required to effectuate international agreements that take the form of executive agreements under U.S. law. However, legislation may be required to authorize or implement many executive agreements. Moreover, Congress through legislation could potentially modify or abrogate the domestic legal effect of any agreement addressing matters which do not fall within the President’s exclusive constitutional purview. For further discussion, see Mulligan, supra note 230, at 6–7. Congress may employ other tools to conduct oversight over non-treaty international agreements, including legislation that requires that the executive branch consult with Congress before or during negotiations, as well as oversight hearings.

While the full Senate votes on whether to convict an impeached official, under Impeachment Rule XI, the Senate may order the Presiding Officer of the Senate to establish a committee of Senators to receive evidence and take testimony prior to the vote.250 This procedure was challenged in Nixon v. United States, which concerned the impeachment and conviction in the Senate of Walter L. Nixon, Jr., former Chief Judge of the U.S. District Court for the Southern District of Mississippi.251 After a criminal trial, Nixon was found guilty of making false statements to a grand jury and was sentenced to prison.252 He was then impeached by the House and tried and convicted by the Senate. During the proceedings in the Senate, the Senate established a committee under Impeachment Rule XI to receive evidence.253 Following his senatorial conviction, Nixon brought suit in federal court, arguing that Rule XI violated the constitutional prescription that the Senate “try” impeachments because, when it is invoked, the full Senate does not take part in evidentiary hearings.254 
The Supreme Court held that the former judge’s claim posed a nonjusticiable political question and was therefore not subject to judicial review.255 The Court decided that “the sole Power” to try

259 The advice-and-consent requirements of the Treaty Clause are not constitutionally required to effectuate international agreements that take the form of executive agreements under U.S. law. However, legislation may be required to authorize or implement many executive agreements. Moreover, Congress through legislation could potentially modify or abrogate the domestic legal effect of any agreement addressing matters which do not fall within the President’s exclusive constitutional purview. For further discussion, see Mulligan, supra note 248, at 6–7.

While the full Senate votes on whether to convict an impeached official, under Impeachment Rule XI, the Senate may order the Presiding Officer of the Senate to establish a committee of Senators to receive evidence and take testimony prior to the vote.268 This procedure was challenged in Nixon v. United States, which concerned the impeachment and conviction in the Senate of Walter L.

272290 That said, congressional committees are not empowered to enforce, or even trigger enforcement of these provisions. Instead, enforcement—as with all criminal provisions—is carried out by the executive branch.

Federal law directly empowers committees to obtain an immunity order from a federal court to compel a witness who has asserted the Fifth Amendment privilege against self-incrimination to testify.292 Under federal law, a court order can be obtained from a United States district court following a two-thirds affirmative vote in the committee conducting the investigation.293 So long as the committee complies with certain procedural requirements, the district court “shall grant” the immunity order when petitioned, although the Attorney General can request to delay the order.294 While an order requires a witness to testify, the Fifth Amendment’s protections prohibit the compelled testimony and any evidence derived from that testimony from being used against the witness “in any respect” in a later criminal prosecution, except one for perjury, false statement, or contempt relating to the testimony.295

Instead, enforcement—as with all criminal provisions—is carried out by the executive branch. With regard to perjury, false statements, and obstruction, a committee may refer a possible offense to DOJ with a recommendation that an investigation be initiated, but the ultimate decision on prosecution is retained by the executive branch.273  
Federal law does, however, directly empower committees to obtain an immunity order from a federal court to compel a witness who has asserted the Fifth Amendment privilege against self-incrimination to testify.274 Under federal law, a court order can be obtained from a United States district court following a two-thirds affirmative vote in the committee conducting the investigation.275 So long as the committee complies with certain procedural requirements, the district court “shall grant” the immunity order when petitioned, although the Attorney General can request to delay the order.276 While an order requires a witness to testify, the Fifth Amendment’s protections prohibit the compelled testimony and any evidence derived from that testimony from being used against the witness “in any respect” in a later criminal prosecution, except one for perjury, false statement, or contempt relating to the testimony.277  
While Congress’s oversight and investigatory powers are broad, they are not unlimited. Besides jurisdictional limitations and other procedural requirements imposed by each house or a particular committee’s rules,278 other constitutional principles restrict committee investigations.

In addition, because a congressional inquiry is part of “lawmaking,” a congressional committee engaged in an investigation generally must observe applicable constitutional restrictions and respect validly asserted constitutionally based privileges.301 Most, though not all, provisions of the Bill of Rights addressing the rights of individuals apply to a congressional investigation.302 For example, the First Amendment prevents a committee from interfering with a witness’s free speech or associational rights without an adequate legislative interest;303 the Fourth Amendment prevents the enforcement of an unreasonably broad subpoena;304 and the Fifth Amendment may be asserted in response to a congressional subpoena when compliance would tend to incriminate the witness.305

In addition, because a congressional inquiry is part of “lawmaking,” a congressional committee engaged in an investigation generally must observe applicable constitutional restrictions and respect validly asserted constitutionally based privileges.283 Most, though not all, provisions of the Bill of Rights addressing the rights of individuals apply to a congressional investigation.284 For example, the First Amendment prevents a committee from interfering with a witness’s free speech or associational rights without an adequate legislative interest;285 the Fourth Amendment prevents the enforcement of an unreasonably broad subpoena;286 and the Fifth Amendment may be asserted in response to a congressional subpoena when compliance would tend to incriminate the witness.287

318 Report language generated as Congress resolves differences in chamber-passed legislation will be titled differently, depending on the resolution method used. Under chamber rules, a joint explanatory statement is a formal product of a conference committee and accompanies a conference report, while under chamber practice an explanatory statement is an informal product as Congress resolves chamber differences using an exchange of amendments between the Houses rather than a conference committee.

However, report language is generally understood to carry legal consequences in at least two circumstances: (1) where report matter is incorporated by reference into its accompanying bill, see Stiff, Regular Appropriations Acts, supra note 318, at 33–36 , and (2) where report matter addresses allocations of appropriations between the various “programs, projects, or activities” of that account, allocations that are generally understood to figure in an agency’s compliance with statutory report-and-wait reprogramming requirements, see Stiff, Power Over Appropriations, supra note 99, at 36–37.

As one appellate court has noted, “there is nothing unconstitutional about . . . such informal cooperation.”327 By the same token, because an agency is not bound by such prior-approval arrangements, an agency can decide to disregard the arrangement and (for example) obligate funds for a particular program even when a committee disapproves of the planned obligations.328
