The Appointment Power: Principal and Inferior Officers

Article II, Section 2, Clause 2 lets the President appoint ambassadors, other public ministers and consuls, judges of the Supreme Court, and all other officers of the United States, with the advice and consent of the Senate. That sentence builds the appointment power into a two-tier system, and almost every exam question about it turns on which tier the officer occupies.

The analysis is mechanical once you know the order of operations. Classify the officer as principal or inferior. Then test the statute Congress wrote against the requirements for that tier. If the statute deviates, the statute falls, not the officer.

Tier one: principal officers

Principal officers include ambassadors, Supreme Court Justices, cabinet secretaries and other high-level executive officers. They require two steps and only two steps: presidential nomination, then Senate advice and consent. There is no abbreviated route and no substitute for the Senate vote.

Crucially, the nominating half belongs to the President alone. Congress cannot confine the President to a pre-approved list, and the Senate cannot propose candidates. What the Senate can do is refuse — it may vote no, or decline to hold hearings at all, without offering any justification. The 2016 nomination of Merrick Garland is the standard illustration: inaction is a permissible use of the confirmation check.

Tier two: inferior officers

An inferior officer is one whose work is directed and supervised by a superior executive official other than the President. For inferior officers, Congress has real flexibility. By law it may vest the appointment in the President alone, in the courts of law, or in the heads of executive departments. Full Senate confirmation can be skipped entirely.

The modern test comes from Edmond v. United States (1997): an officer is inferior if her work is directed and supervised at some level by an officer below the President who was himself appointed by presidential nomination and Senate confirmation. Cite Edmond rather than the looser shorthand about being removable by a superior; the supervision framing is what courts apply to close cases.

Exam tip: Congress may create the office, define its duties and choose among three appointing authorities for inferior officers. What Congress may never do is appoint an officer of the United States itself, through its members, its committees or its own officers.

Scheme in the statute	Officer type	Valid?
President nominates, Senate confirms	Principal	Yes — the constitutional default
Appointment vested in a department head	Inferior	Yes
Appointment vested in a federal court	Inferior	Yes
Appointment vested in the President alone	Inferior	Yes
Speaker and President pro tempore appoint	Either	No — Buckley v. Valeo
President must choose from a Senate list	Principal	No — nomination is exclusive

Match the appointing authority to the tier; a mismatch invalidates the statute.

The three cases that decide close calls

Buckley v. Valeo (1976) struck down a scheme in which Congress itself appointed members of the Federal Election Commission, some by the Speaker and some by the President pro tempore, who then exercised executive law-enforcement functions. The holding is categorical: only the President, courts of law, or department heads may appoint officers of the United States, and the latter two only for inferior officers.

Morrison v. Olson (1988) upheld the independent counsel under the now-lapsed Ethics in Government Act as an inferior officer despite substantial investigative and prosecutorial power, because she was removable by the Attorney General, had limited jurisdiction, and lacked policymaking authority. Seila Law LLC v. Consumer Financial Protection Bureau (2020) then pushed in the other direction, treating a single director with sweeping regulatory authority as a principal officer even though the position sits outside the cabinet. The lesson is that power and independence control, never the label Congress attaches.

Worked example

Congress enacts a statute requiring the President to appoint all ambassadors from a list of five candidates pre-selected by the Senate Foreign Relations Committee. The President nominates a qualified ambassador who is not on the list, and the Senate confirms her. The committee challenges the appointment.

Ambassadors are principal officers, so the constitutional route is presidential nomination followed by Senate advice and consent. The statute inverts that structure: by narrowing the field to five committee choices, it effectively relocates the nominating power to a Senate committee. Nothing in Article II permits the Senate to propose nominees, and the confirmation that occurred here does not cure the defect, because the constraint bit before nomination. Conclusion: the appointment itself is valid, because the President nominated freely and the Senate confirmed, but the pre-selection statute is unconstitutional and unenforceable.

Change one fact. Suppose the statute instead required any nominee to have five years of diplomatic experience. A qualification requirement of general application is a far weaker intrusion than a list of names, and such conditions have historically been tolerated, so the answer shifts toward validity. The distinction is between regulating the class of eligible persons and choosing the person.

Common mistakes that cost points

Treating Senate confirmation as a shared nominating power. The Senate confirms or rejects; it never nominates.
Classifying officers by job title instead of actual authority and supervisory structure.
Assuming every agency head is a principal officer, or that every non-cabinet official is inferior.
Citing only the removable-by-a-superior shorthand instead of the Edmond supervision test.
Believing Congress can appoint executive officers through an internal mechanism. It cannot, under any structure.
Extending the clause to state officials or private contractors. It reaches federal officers only.
Forgetting that multimember commissions and single-director agencies are treated differently once removal enters the picture.
Invalidating the officer’s appointment when the correct target is the unconstitutional statute.

Frequently asked questions

Can Congress ever appoint an officer of the United States?

No. Buckley v. Valeo forecloses it completely. Congress may create offices and prescribe duties, but the appointing authority must be the President, a court of law, or a department head.

How do I tell a principal officer from an inferior one?

Apply Edmond: ask whether some Senate-confirmed officer below the President directs and supervises the officer’s work. If yes, the officer is inferior. If the officer answers to no one but the President, she is principal.

Does the Senate have to vote on a nomination?

No. The Senate may decline to act, and it owes no explanation. The President cannot compel a vote, and the vacancy simply persists.

Appointments in California and Los Angeles County government, 2026

The federal question is whether an official is a principal officer requiring Senate confirmation or an inferior officer whose appointment Congress may vest elsewhere, a distinction Lucia v. SEC (2018) applied to administrative judges. California and Los Angeles County resolve the same structural problem by very different means, and the county’s answer is unusually democratic.

Los Angeles County elects officials that most jurisdictions appoint. The Sheriff, the District Attorney and the Assessor are chosen by county-wide election rather than named by the Board of Supervisors, which gives them independent political legitimacy and makes them difficult for the Board to direct. Department heads, the chief executive and the Los Angeles County Counsel are appointed by the Board, and charter reform approved by voters contemplates an elected county executive on a phased schedule.

Appointment mechanics worth knowing:

Judicial appointments have a distinctive filter. The Governor fills vacancies, with appellate appointments confirmed by the Commission on Judicial Appointments rather than the Legislature.
Superior court judges stand for election. Los Angeles County judges appear on the ballot, so appointment and election coexist.
Senate confirmation applies to many state posts. Agency heads and board members generally require confirmation within a statutory period.
Vacancies in county elected offices are filled by the Board. An appointee then serves until the next election.
Split appointment insulates agencies. Distributing appointments among the Governor and legislative leaders is California’s substitute for removal protection.
Civil service governs the rest. Most county positions are filled by competitive examination under the charter, not by discretionary appointment.

In 2026, ask who appoints, who confirms and who can remove, because the three answers define the office. Read with the removal power, the nondelegation doctrine and bicameralism and presentment.

Next steps

This doctrine is almost always tested alongside its sister rule, so read the Take Care Clause for the supervision duty that motivates presidential control, then the impeachment power for the only route to removing a federal judge, and bicameralism and presentment for the broader limits on congressional self-aggrandisement.
