WASHINGTON — President Donald Trump enters the Supreme Court's new term with an unusual record: the conservative majority he helped create has dramatically expanded presidential control over parts of the federal government while simultaneously blocking some of his most consequential attempts to stretch powers granted by Congress and the Constitution.
The justices begin their nine-month term Monday with another series of disputes capable of defining how far Trump can push executive authority during his second presidency. Immigration is already at the center of the docket, with the court agreeing to examine mandatory detention without bond hearings and the rapid removal of migrants to countries other than their own. The administration is also asking the justices to consider disputes involving transgender military service, asylum restrictions, academic research funding and the appointment of federal prosecutors.
The emerging legal battle is therefore broader than whether a conservative Supreme Court generally supports a Republican president. Decisions from the previous term suggest the more consequential question is what kind of presidential power Trump is asserting. The court has shown considerable willingness to strengthen presidential authority over officials and agencies within the executive branch, but it has been more resistant when the administration tries to derive sweeping powers from statutes that Congress wrote more narrowly.
That distinction produced one of Trump's biggest victories when the court overturned a precedent dating to 1935 and expanded the president's ability to control independent federal regulators. The ruling strengthened White House authority over agencies Congress had historically insulated from direct presidential removal power, altering a longstanding feature of the federal government's structure and giving Trump considerably greater control over executive-branch personnel.
But the same conservative court rejected Trump's sweeping global tariffs in February, concluding that the emergency statute invoked by the administration did not provide the authority required for such an extensive trade regime. The justices also blocked his attempt to remove Federal Reserve Governor Lisa Cook and rejected his effort to restrict birthright citizenship for children born in the United States to parents who are unlawfully or temporarily present.
The birthright-citizenship ruling was particularly consequential because the court addressed the constitutional question directly. Trump's January 2025 executive order sought to reinterpret the Fourteenth Amendment's Citizenship Clause, but the justices concluded that children born on U.S. soil to parents unlawfully or temporarily present remain citizens at birth. The decision demonstrated that the court's conservative composition does not automatically translate into approval of every expansive presidential interpretation.
Trump also lost when he sought to deploy National Guard troops in the Chicago area, adding another example in which the justices declined to accept the administration's claimed authority. Yet those defeats occurred alongside numerous emergency decisions allowing other Trump policies to proceed while litigation continued in lower courts, including parts of his immigration crackdown, restrictions affecting transgender people and reductions in federal research funding.
The result is a Supreme Court record that cannot be reduced neatly to either support for or resistance to Trump. The court has repeatedly strengthened the presidency as an institution while showing that statutory and constitutional boundaries can still defeat specific presidential actions. That distinction could become even more important during the new term because several cases now approaching the justices involve policies designed to substantially expand the administration's ability to act without lengthy judicial or administrative processes.
One of the most consequential disputes concerns the administration's policy requiring mandatory detention of many immigrants living illegally in the United States while their deportation proceedings continue. Under guidance issued by the Department of Homeland Security in July 2025, affected migrants can be held without receiving a bond hearing even when proceedings take months or potentially years. Numerous legal challenges have produced conflicting lower-court decisions over whether federal immigration statutes actually authorize that approach.
The Supreme Court agreed Thursday to resolve the dispute. The case could affect large numbers of people because immigration judges historically distinguished between migrants detained shortly after entering the country and people who had already established lives and community ties inside the United States. The administration argues that federal law permits mandatory detention more broadly, while challengers contend that long-term detention without access to a bond hearing exceeds the government's statutory authority.
A second immigration dispute will examine the administration's ability to rapidly deport migrants to countries other than their own. Together, the cases could determine how much procedural flexibility the executive branch possesses while carrying out Trump's mass-deportation agenda, one of the defining policies of his second term.
Other potential cases could expand the constitutional confrontation beyond immigration. The administration has appealed decisions involving Trump's ban on transgender people serving in the military, cuts to academic grants, disputes over federal prosecutors and the suspension of asylum at the U.S.-Mexico border. The justices have not agreed to hear all of those appeals, but decisions on whether to accept them will shape the term over the coming months.
The transgender military dispute could become particularly significant because the court's conservative majority previously allowed Trump's policy to operate while a separate legal challenge proceeded. The administration is now seeking review of another decision concluding that the policy appeared motivated by unconstitutional discrimination. The court has also recently issued decisions affecting transgender athletes, gender markers on passports and state restrictions on gender-affirming medical care for minors, making the new military dispute part of a broader constitutional debate already moving through the judiciary.
Trump's relationship with the court has meanwhile become increasingly contentious despite his role in creating its current ideological balance. During his first presidency he appointed Gorsuch, Kavanaugh and Barrett, establishing the 6-3 conservative majority that has reshaped American law on abortion, guns, religion, federal regulation and other major issues.
Trump said this week that he regretted those appointments because the three justices had ruled against him too frequently. His criticism intensified after defeats involving tariffs and election-related disputes, and he has publicly questioned why judges he selected have not produced decisions he considers favorable. Trump nevertheless said he was seeking what he regarded as correct legal decisions rather than personal loyalty from the justices.
The tension illustrates the institutional stakes surrounding the new term. Supreme Court justices receive lifetime appointments and do not formally represent the presidents who nominate them, even though presidential appointments can reshape the court's ideological direction for decades. Trump's three nominees have participated in decisions producing major conservative victories while also joining rulings that rejected important elements of his second-term agenda.
The next series of cases could provide a clearer picture of where that court draws the boundary around presidential power. When Trump asserts authority over executive officials, the conservative majority has demonstrated substantial sympathy toward a strong presidency. When his administration claims broad powers that the justices conclude Congress did not grant, the result has sometimes been markedly different.
That makes the new term less a simple test of whether Trump's Supreme Court will support Trump than a continuing constitutional argument over where presidential authority ends. Immigration detention, deportation, military policy and potentially asylum and federal spending will give the justices multiple opportunities to answer that question, ensuring that the institution Trump helped transform will again play a central role in determining the reach of his presidency.
