Presidential Power Overreach: A Constitutional Analysis of Trump v. Slaughter and Trump v. Illinois
Published: December 2025•10 min read
Two landmark Supreme Court cases—Trump v. Slaughter and Trump v. Illinois—demonstrate President Donald Trump's attempts to exceed constitutional limits on presidential power through the "unitary executive" theory. These cases reveal critical principles about Article VI oath requirements, separation of powers, and the consequences of executive overreach.
Trump's Executive Overreach and Constitutional Oath Violations
- The Supreme Court cases Trump v. Slaughter and Trump v. Illinois demonstrate President Donald Trump's attempts to exceed constitutional limits on presidential power through the "unitary executive" theory.
- The Constitution's Article VI, Clause 3, establishes an oath requirement that binds all executive officers to support the Constitution, and violating this oath can result in actions being void ab initio (void from inception) and expose officers to personal liability.
- Trump's removal of Rebecca Kelly Slaughter from the Federal Trade Commission without statutory cause violates his Article VI oath, separation of powers, and the constitutional structure of independent agencies, as established by the Supreme Court in Humphrey's Executor v. United States.
- The authority to hold office is derived from the constitutional oath, and violating this oath by exceeding constitutional limits or refusing to follow constitutional requirements means acting outside lawful authority.
Legal Consequences of Void Ab Initio Doctrine
- The void ab initio doctrine applies to actions taken without lawful authority, making them void from inception with no legal effect, and this doctrine has implications for Trump's removal of Slaughter as commissioner.
- If Trump's removal of Slaughter is deemed void, Slaughter remains the lawful commissioner, and any actions taken by a replacement commissioner are also void, with potential consequences including:
- Back pay and restoration to office for Slaughter
- Personal liability for Trump
- Invalidation of all actions taken by unlawful replacement
Federalization Order and Constitutional Violations
- The Supreme Court ruled against Trump, stating that he exceeded his constitutional and statutory powers by attempting to federalize the Illinois National Guard without meeting statutory requirements.
- Trump's federalization order violates multiple constitutional principles, including:
- The Posse Comitatus Act's prohibition on military law enforcement
- The Tenth Amendment's reservation of powers to the states
- Separation of powers between federal and state governments
- The Supreme Court's ruling and similar cases in other states (such as Oregon, California, and Tennessee) reveal a pattern of executive overreach by Trump, who has repeatedly attempted to deploy military forces without lawful authority, potentially leading to personal liability for himself and other officers involved.
Constitutional Safeguards and Multi-Front Defense Strategies
- The US Constitution provides various mechanisms to limit executive power, including oversight, statutory limits, and state remedies such as quo warranto actions and interposition.
- Individuals harmed by executive overreach have avenues for redress, including:
- Section 1983 claims for constitutional violations
- Bivens actions against federal officers
- Habeas corpus petitions for unlawful detention
- Public records requests to expose violations
- Defending constitutional limits requires a multi-front approach, involving courts, Congress, states, and civil society, to establish clear precedents, hold officers accountable, and educate citizens about constitutional principles.
