1.2 Statutory Authority, Enabling Legislation & the ABA Model Code

Statutory Authority, Enabling Legislation & the ABA Model Code

Public procurement is fundamentally an exercise of sovereign governmental authority. Unlike commercial purchasing in the private sector—where corporate buyers operate under broad management discretion and flexible commercial trade customs—public procurement operates within a strictly defined statutory framework established by constitutional law, legislative enactments, administrative codes, and municipal charters. Every dollar committed by a public purchasing official must trace its legitimacy back to an affirmative grant of legal authority.

Constitutional & Statutory Foundations

In the American legal system, government power is divided among the legislative, executive, and judicial branches. The authority to raise public revenues, appropriate funds, and establish the parameters for spending taxpayer money resides primarily with the legislative branch (the United States Congress at the federal level, state legislatures at the state level, and county commissions, city councils, or school boards at the local level).

When a public entity enters into a contract to procure goods, services, or construction, it exercises delegated executive power pursuant to legislative authorization. This authorization appears in two primary forms:

1. Enabling Legislation: Specific statutes enacted by a legislative body establishing a public agency, defining its public mission, and explicitly granting it the power to enter into binding legal agreements, own property, and expend appropriated public funds.
2. Procurement Acts and Administrative Codes: Codified statutory frameworks (such as state procurement codes or municipal purchasing ordinances) that prescribe the exact mandatory procedures through which contracts must be solicited, evaluated, awarded, administered, and terminated.

Agency Law in the Public Sector: Express vs. Implied vs. Apparent Authority

The relationship between a government agency, its purchasing personnel, and private vendors is governed by specialized principles of administrative agency law. In private commerce, courts frequently protect third-party vendors who rely in good faith on the outward representations of corporate agents. In the public sector, however, the protection of the public treasury and statutory supremacy override private commercial reliance.

1. Express Authority

Express authority is the explicit, written power granted directly to a public official by statute, charter, administrative regulation, or a formal written delegation of authority. For example, a state procurement code may state: "The Chief Procurement Officer shall have the authority to solicit bids and execute contracts for supplies and services up to $500,000." Express authority leaves no ambiguity regarding the identity of the agent, the permitted subject matter, or the contractual monetary limits.

2. Implied Authority

Implied authority consists of those unstated powers that are reasonably and legally necessary to carry out the express powers granted by statute. Public statutes cannot anticipate every operational step required to execute a procurement. Therefore, courts recognize that an official with express authority to purchase goods also possesses implied authority to perform necessary incidental tasks, including:

• Establishing standard administrative bid opening schedules and procedures;
• Issuing written solicitation addenda to clarify ambiguous technical specifications;
• Holding mandatory pre-bid conferences;
• Rejecting non-responsive bids or non-responsible offerors; and
• Canceling an Invitation for Bids when doing so serves the best interest of the governmental jurisdiction.

Implied authority must always be directly connected to, and supportive of, an underlying express grant of power. Implied authority can never contradict or expand beyond express statutory limits.

3. Apparent authority and verification

Apparent authority concerns a third party's reasonable belief created by the principal's conduct. Actual authority is especially important in government contracting: an employee's title, business card, or verbal assurance is not a safe substitute for a valid delegation. Federal contracting generally requires actual authority. State and local doctrines, estoppel exceptions, and restitution remedies vary, so do not assume that every jurisdiction reaches the same result.

A buyer should check who may sign, the spending ceiling, commodity restrictions, board approvals, and effective dates of the delegation. An engineer may inspect work without authority to increase the price. A finance officer may certify funds without authority to select the supplier. Communicate those boundaries at kickoff and maintain the delegation in the file.

Dillon's Rule vs. Home Rule Authority

Local governments (cities, towns, counties, and special districts) derive their existence and power directly from their state government. How broadly or narrowly local procurement officials may interpret their statutory powers depends on whether their state follows Dillon's Rule or grants Home Rule authority.

Dillon's Rule in Practice

In a Dillon's Rule jurisdiction, if a county wants to use a progressive Design-Build delivery method for a new municipal justice center, the county purchasing agent must first verify whether the state legislature has passed a statute explicitly authorizing counties to use Design-Build. If the state code only authorizes traditional Design-Bid-Build, any contract executed under Design-Build would be unlawful and void, regardless of how beneficial it might be to the taxpayers.

Home Rule in Practice

In a Home Rule jurisdiction, a municipality operating under a voter-approved Home Rule charter possesses plenary power over municipal affairs. The city council can enact an ordinance adopting progressive procurement practices, establishing specialized qualification criteria, or setting informal small purchase thresholds higher than state baseline rules, provided the ordinance does not conflict with state constitutional mandates or state laws governing statewide concerns.
