Major cases involving Trump before the US Supreme Court
Since Donald Trump returned to office in January, a number of high-stakes legal battles involving his administration have made their way to the U.S. Supreme Court. These cases tend to involve disputes over executive power, with several directly asking how far a president can reshape federal agencies, impose tariffs, and remove officials who are supposed to have independence under existing laws.
One of the foremost cases involved President Trump’s bid to fire Federal Reserve Governor Lisa Cook. Trump contends that prior claims of misconduct (particularly alleged mortgage fraud) give him authority to do so. Cook disputes this, saying the allegations are a pretext, and more fundamentally that the law governing the Fed only allows removal of governors “for cause,” a standard meant to protect central bank independence.
Another major case is about the use of the International Emergency Economic Powers Act (IEEPA) to impose sweeping import tariffs. The administration has used IEEPA in novel ways — notably to impose tariffs under the claim that trade deficits or other economic issues constitute an “unusual and extraordinary threat.” These IEEPA-based tariffs are now being challenged in court, as plaintiffs argue that the statute was never intended to authorize general tariff programs and that the president is exceeding his legal authority.
The Supreme Court has agreed to hear arguments in some cases on an expedited schedule. For instance, the tariffs case has been scheduled for oral arguments on November 5, 2025. The outcome of these cases could reshape the boundaries of presidential authority — especially concerning economic tools and agency oversight.
Broadly, many of Trump’s actions — including immigration changes, birthright citizenship orders, changes to agency governance, etc. — have also faced legal challenges, some moving through lower courts, others awaiting review at the Supreme Court. These cases represent critical tests of constitutional limits (checks and balances) and the role of independent agencies versus presidential control.
Key Legal Outcomes

The Supreme Court has agreed to hear whether Trump can remove Fed Governor Lisa Cook based on alleged misconduct, and whether that meets the “for cause” requirement. Reuters
-
The Court will consider whether the IEEPA statute authorizes broad presidential tariffs or whether the president has overstepped in using it for substantial trade policy decisions. Reuters+1

-
The Court’s decisions in these cases may establish new precedents concerning the limits of executive power over independent agencies, the scope of emergency economic powers, and the definition of “for cause” in removal statutes. These decisions could have lasting implications beyond the particular individuals or policies involved. Reuters+1
Why It Matters
-
These cases could significantly expand or clarify presidential control over federal agencies (especially independent ones), affecting how checks and balances work in practice.
-
The use of emergency powers (IEEPA) to impose tariffs is relatively novel at this scale, meaning outcomes here will affect economic policy, trade relations, and constitutional limits for years to come.
-
Decisions in these cases may either protect or erode norms of regulatory and agency independence — which affects everything from monetary policy (e.g. Fed) to consumer/antitrust regulation.
-
Legal clarity on “for cause” removal standards for agency officials will impact how future administrations can staff and control regulatory and independent bodies.
-
For business, trade, and the economy: decisions around tariffs and executive powers have ripple effects across industries, imports/exports, international relations, markets, and investor expectations.
