On November 14, 1979, President Jimmy Carter declared a national emergency in response to the Iranian hostage crisis. He used it to freeze Iranian government assets held in the United States.
The hostages were released on January 20, 1981. The emergency was not.
The national emergency declared in response to a crisis that ended forty-four years ago is still in effect today. It has been renewed annually, as required by the National Emergencies Act, by every president of both parties in the four and a half decades since. Its statutory authority continues to govern the legal status of Iranian assets in the United States.
This is not the oldest active emergency, though it is among them. There are currently more than forty national emergencies in effect. They cover Iran, narcotics trafficking, weapons of mass destruction, destabilizing actions in foreign countries, cyber threats, and dozens of other declared crises. Some have genuine ongoing relevance. Others persist because no president has found it advantageous to end them, and Congress has not required it.
The national emergency is now a permanent instrument of executive governance, a tool available to the president, at any time, for any qualifying reason, granting access to hundreds of special statutory powers that bypass the normal legislative process. And the defining characteristic of this instrument is that once declared, it tends to stay declared.
What an Emergency Declaration Actually Does
The word “emergency” implies a temporary, extraordinary condition. In the legal architecture of the American executive, it implies something closer to a standing reservoir of authority that the president can tap by filing a declaration.
The Congressional Research Service has identified approximately 136 statutory powers that become available to the president upon declaration of a national emergency. These powers span the full range of executive function: economic controls, military authorities, transportation, communications, and the ability to direct resources and compel action in ways that would otherwise require legislative authorization.
Among the available powers: the International Emergency Economic Powers Act allows the president to regulate international commerce, freeze assets, and impose sanctions without congressional approval. The Defense Production Act allows the president to direct private companies to prioritize federal contracts and produce specified goods. The National Guard and Reserve can be called up. Certain due process protections can be suspended for designated enemy combatants.
None of these powers require a vote. None require congressional approval before the fact. The National Emergencies Act of 1976 requires the president to notify Congress when an emergency is declared and to renew it annually, but provides no mechanism to prevent the declaration or terminate the emergency without an affirmative act of Congress that would have to override a presidential veto.
The legislature that was supposed to be the check on executive emergency power has, in practice, been relegated to observer status.
COVID-19 as the Full Demonstration
Every national emergency before 2020 was significant in its own domain. The COVID-19 emergency demonstrated what emergency power looks like when it is fully activated across the entire domestic economy and every level of government simultaneously.
The federal public health emergency declared in January 2020 remained in effect for over three years, until May 2023. During that period, emergency authority was used to justify:
The eviction moratorium, the CDC issued a nationwide ban on evictions under the Public Health Service Act, an authority Congress had never understood to cover housing policy. The Supreme Court ultimately struck it down in 2021, but not before it had governed millions of tenant-landlord relationships for over a year through an agency rule backed by emergency authority.
Student loan payment suspension, the Department of Education suspended student loan payments and interest accrual for over three years under the HEROES Act, a post-9/11 statute authorizing the Secretary to “waive or modify” loan provisions in a national emergency. The administration subsequently attempted to use the same authority for broad loan cancellation; the Supreme Court struck it down.
Vaccine mandates, the Occupational Safety and Health Administration issued an emergency rule requiring vaccination or weekly testing for employers with 100 or more employees, affecting over 80 million workers. The Supreme Court stayed the rule, but the mechanism, OSHA using emergency rulemaking authority under a general workplace safety statute to impose a nationwide health policy, demonstrated how far emergency authority could extend.
School and business closures, while state governors issued most closure orders, federal emergency declarations provided legal cover and financial mechanisms that effectively made the federal posture determining for state decisions. The practical result was nationwide policy coordination through executive channels without a single vote of Congress on the specific measures implemented.
The COVID emergency did not produce tyranny. The measures implemented were responses to a genuine crisis, and their merits and costs remain legitimately debated. But the structural demonstration was unmistakable: the executive branch, operating under emergency authority, can affect the daily lives of 335 million people, where they work, whether their children attend school, what they are required to do with their bodies, through administrative and executive action, without any requirement for legislative authorization of the specific policies implemented.
The Warning About Permanent Exceptions
The Anti-Federalists who most specifically warned about executive emergency power were those who had read their history. They knew that the transition from republic to tyranny in Rome, in England, and in the continental European states had rarely occurred through direct seizure of power. It had almost always occurred through the gradual normalization of emergency exception, a temporary grant of extraordinary authority that, once established as precedent, was impossible to fully withdraw.
Cato, analyzing the executive article, warned that the president’s powers would expand during crises in ways that would not fully contract afterward. He argued that the combination of military command, foreign affairs authority, and emergency statutory powers made the executive dangerous not because any individual president would be malicious but because the institutional accumulation of authority, once established, would persist and grow regardless of who held the office.
Brutus was equally specific about the danger of concentrated executive power in a large republic: the president, representing a national constituency but governing at a vast distance from ordinary citizens, would in times of crisis become practically unaccountable. The mechanisms of accountability, elections, congressional oversight, judicial review, all operate on timescales that cannot constrain executive emergency action in real time. By the time the political or legal response mobilized, the emergency measures would be facts on the ground.
What neither writer could fully anticipate was the statutory architecture that Congress would build in the twentieth century, the proliferation of emergency authorities embedded in statute, waiting to be activated by declaration, that effectively gave the modern president a reserve of legislative power accessible without a vote.
The Bipartisan Record
Presidents of both parties have declared emergencies, used emergency authorities aggressively, and declined to terminate emergencies once the triggering crisis passed.
President George W. Bush declared a national emergency on September 14, 2001, that established the legal basis for the surveillance authorities documented in an earlier article in this series, authorities that persist today under successive emergency renewals and statutory authorization.
President Obama declared emergencies related to the H1N1 pandemic, the Deepwater Horizon oil spill, and continued all the post-9/11 emergency authorities of his predecessor while adding new ones related to cybersecurity and foreign policy crises.
President Trump declared a national emergency to redirect congressionally appropriated military construction funds to border wall construction, using emergency authority to spend money Congress had explicitly declined to appropriate for that purpose. He also declared an emergency to impose tariffs under the International Emergency Economic Powers Act, bypassing the normal trade authority process.
President Biden declared the COVID-19 emergency expired while using the HEROES Act and other emergency-adjacent authorities for student loan policy and maintaining post-pandemic emergency structures for extended periods.
The pattern across administrations: emergency declarations go up easily and come down reluctantly. The 136 powers available upon declaration are too useful to surrender. And Congress, which could terminate emergencies through concurrent resolution, has almost never done so.
The Structural Fix
The National Emergencies Act of 1976 was itself a reform measure, passed after Watergate and Vietnam to reassert congressional oversight of executive emergency power. It established the renewal requirement and created a mechanism for congressional termination. It did not establish automatic sunset. It did not limit the duration of emergencies. It did not require affirmative congressional approval before emergency powers could be exercised.
What genuine structural constraint would require: automatic expiration of emergency declarations after sixty or ninety days unless Congress affirmatively votes to extend them, not a concurrent resolution that the president can ignore, but an affirmative vote that the president must sign or override by veto, in either case forcing a public record of congressional position on each emergency. A defined and limited catalog of emergency powers, not the current open architecture of 136+ statutory authorities that can be assembled into novel combinations under a single declaration.
The Anti-Federalists wanted the executive constrained to ordinary legal channels except in genuinely extraordinary, time-bounded crises. What we have built is the opposite: an architecture in which the emergency channel is always available, always useful, and nearly impossible to fully close once opened.
A national emergency declared in 1979 is still in effect. That is not an emergency. It is a structural condition. And the distinction, between a genuine temporary exception and a permanent expansion of executive authority through emergency declaration, is exactly the distinction the Anti-Federalists wanted built into the constitutional design.
It was not built in. Forty-four years of the Iran emergency is the result.
