The Supreme Court is set to make a decision soon regarding President Donald Trump’s application of wartime emergency laws, specifically concerning his implementation of significant tariffs on various countries. This situation has sparked meaningful discussions around what’s termed the “grave issue doctrine,” which essentially examines the ability of courts to limit executive power in specific situations.
During oral arguments about Trump’s tariffs last November, the justices delved into the Major Questions Doctrine. This doctrine provides a framework for courts to restrict executive actions that hold “extreme economic or political significance.” The conversation particularly revolved around how this relates to Trump’s invocation of the International Emergency Economic Powers Act (IEEPA) to propose global and reciprocal tariffs.
The plaintiffs argued that Trump’s use of IEEPA to impose high import duties lacks legal grounding since the act doesn’t explicitly use the term “tariff.” Instead, it allows the president to “regulate imports” amid a national emergency—an interpretation the plaintiffs contest as inadequate for triggering the Major Questions Doctrine.
One notable statement from the court during earlier reviews was that Congress couldn’t have intended to give the executive branch such vague, expansive taxing authority, especially on potentially trillions of dollars worth of economic impact for American businesses and consumers.
In November, Trump’s lawyers contended that IEEPA’s provisions were akin to tariffs. U.S. Attorney General D. John Sauer admitted that while the act doesn’t directly grant agencies the power to set tax rates, he argued that deducing such authority from the act is, well, just common sense.
However, the justices have yet to decide on this matter. A previous ruling from the U.S. Court of International Trade last year reinforced the idea that President Trump, as commander-in-chief, does not have “unlimited authority” to levy tariffs through emergency law. A panel of judges unanimously blocked such attempts.
The court emphasized two principles in their ruling: the non-delegation principle and the principal inquiry principle, both aimed at preventing branches of government from relinquishing their constitutional powers.
This discussion lingered in November, as justices queried administration lawyers about how IEEPA relates to tariffs and the rights surrounding taxation. They were particularly interested in the limitations on executive power if the ruling were in Trump’s favor.
Experts suggest that the court may reference the Major Questions Doctrine in its decision, indicating a potential blockade against Trump’s tariff plans.
That said, the Supreme Court has expedited this case and is anticipated to release a ruling shortly. There’s almost a lack of precedent on the primary question at hand, as highlighted by legal analyses from academic institutions.
The Major Questions Doctrine was officially referenced for the first time in 2022 when the Supreme Court invalidated EPA’s emissions standards under the Clean Power Plan. Previously, this doctrine existed in a more ambiguous legal space, a fact noted by Justice Elena Kagan in her dissent where she observed how courts selectively apply textual analysis.
On a different note, one aspect that might tilt in Trump’s favor is the recognition that tariff litigation intersects with foreign policy, an area where the executive branch often retains greater court respect.
Yet, indications from oral arguments suggest that justices lean toward preventing Trump from utilizing IEEPA for his high-tariff ambitions, expressing surprise that a president might apply the law in such an expansive manner. They also probed why more congressional authorization wasn’t sought for this unprecedented use of authority.
In response, Sauer noted the law’s design was intended to empower the executive in the face of critical emergencies. So, the next steps seem quite pivotal for the future of tariff regulations under emergency law.
