The Constitutional Case Against Ambiguous Legislation
September 17, 2026
When Congress passes legislation, it has a constitutional responsibility to define specific statutory rules. For decades, however, lawmakers in Washington have consistently drafted ambiguous statutes that lack clear mandates. By leaving these laws open-ended, Congress effectively transfers its legislative duties to the executive branch, allowing administrative agencies to fill in the critical details without direct accountability to the voters.
Furthermore, the common defense that Congress lacks the technical expertise to draft precise regulations is entirely unfounded. Executive agencies employ dedicated legislative affairs personnel and subject matter experts whose specific purpose is to provide detailed testimony and recommendations to congressional committees. Congress has full access to this specialized knowledge; its duty is to codify those technical details directly into the text of the statute. By failing to write these specific recommendations into law, Congress allows shifting administrations to alter regulations at whim. Codifying these explicit details is the only way to establish permanent, binding mandates that ensure any future president is bound by the constitutional obligation to "take Care that the Laws be faithfully executed." (US Constitution, Article 2, Section 3)
The delegation doctrine is the legal principle that has allowed Congress to transfer portions of its lawmaking authority to executive branch agencies. Historically, the judiciary permitted this practice provided that Congress established an "intelligible principle" to guide agency discretion. For example, broad mandates directing agencies to protect "public health" or "national security" were treated as legally sufficient guidelines.
However, a robust constitutional counter-movement enforces the nondelegation doctrine. This principle dictates that Congress cannot divest itself of its core legislative powers. When Congress surrenders broad authority without an explicit mandate, it disrupts the constitutional balance of powers. As president, I will protect this balance and compel Congress to fulfill its legislative function by refusing to sign open-ended statutes into law.
For decades, lawmakers have drafted broad, non-specific statutes regarding complex regulatory sectors, effectively shifting the responsibility of formulating substantive rules to unelected agency officials.
The legal landscape is shifting. Under the Major Questions Doctrine, the Supreme Court has clarified that the executive branch lacks the authority to interpret ambiguous or vague legislation to implement regulatory changes of vast economic or political significance. Congress must explicitly state its statutory intent. I will strictly reinforce this standard from day one in the White House. Any bill that relies on statutory ambiguity to pass regulatory authority to the executive branch will be returned to Congress with a presidential veto.
Statutory ambiguity poses a direct threat to due process. Under the constitutional Void-for-Vagueness Doctrine, a law is invalid if its terms are so poorly defined that an ordinary citizen cannot clearly understand what conduct is required or prohibited.
When Congress leaves statutory boundaries undefined, it grants law enforcement and regulatory agencies unchecked discretion to define enforcement parameters on a case-by-case basis. This structural flaw leads to arbitrary, unpredictable, and potentially discriminatory enforcement. Stable governance requires clear, predictable statutory rules rather than administrative uncertainty.
The primary reason Congress relies on vague legislation is to secure political cover. By passing broad statutes with popular titles, lawmakers claim credit for addressing national issues while insulating themselves from the political consequences of the actual regulations. When the resulting administrative rules prove disruptive or unpopular, members of Congress routinely deflect blame onto the executive agencies. This practice erodes transparency and undermines federal accountability.
The Constitution separates federal powers deliberately: Congress possesses the sole authority to write the laws, and the President bears the explicit duty to ensure that those laws are faithfully executed. A president cannot faithfully execute a statute that fails to provide specific mandates.
Under my administration, the practice of issuing regulatory blank checks will end. If Congress intends to enact federal policy, it must draft explicit statutory language, vote transparently, and accept full accountability for the outcomes. Legislation that fails to meet this standard will be vetoed.
