In American Federation of Government Employees, AFL-CIO v. Trump (2018), Jackson invalidated provisions of three executive orders that would have limited the time federal employee labor union officials could spend with union members, the issues that unions could bargain over in negotiations, and the rights of disciplined workers to appeal disciplinary actions. She ruled that the executive orders violated the right of federal employees to collectively bargain, as guaranteed by the Federal Service Labor-Management Relations Statute.
In 2018, Jackson dismissed 40 wrongful death and product liability lawsuits stemming from the disappearance of Malaysia Airlines Flight 370, which had been combined into a single multidistrict litigation.
In 2019, in Center for Biological Diversity v. McAleenan, Jackson ruled that the Trump administration could not waive environmental regulations to build a wall on the border between the United States and Mexico.
In 2019, Jackson issued a preliminary injunction in Make The Road New York v. Department of Homeland Security had violated the Administrative Procedure Act (APA) because its decision was arbitrary and capricious and the agency did not seek public comment before issuing the rule.
One of Jackson's most notable rulings came in Committee on the Judiciary v. McGahn, in which the House Committee on the Judiciary sued former White House Counsel Don McGahn to compel him to comply with the subpoena to appear at an impeachment inquiry hearing on issues of alleged obstruction of justice by the Trump administration. McGahn declined to comply with the subpoena after President Donald Trump, relying on a legal theory of executive testimonial immunity, ordered McGahn not to testify. In a lengthy opinion, Jackson ruled in favor of the House Committee and held that senior-level presidential aides "who have been subpoenaed for testimony by an authorized committee of Congress must appear for testimony in response to that subpoena" even if the president orders them not to do so. Jackson rejected the administration's assertion of executive testimonial immunity by holding that "with respect to senior-level presidential aides, absolute immunity from compelled congressional process simply does not exist". According to her, that conclusion was "inescapable precisely because compulsory appearance by dint of a subpoena is a legal construct, not a political one, and per the Constitution, no one is above the law." Jackson's use of the phrase "presidents are not kings" gained popular attention in subsequent media reporting on the ruling.

Perspectives and Impact
Justice Jackson brings a unique perspective to the Supreme Court, shaped by her experiences as a Black woman, a former public defender, and a trial court judge. She is the only currently sitting justice that has experience as either a trial court judge or a defense attorney. Her understanding of the law is informed by a deep commitment to justice, fairness, and equality.
Her appointment to the Supreme Court is not only a personal achievement but also a significant milestone for the nation. It reflects a growing recognition of the importance of diversity and inclusion in the legal profession and in positions of power. As the first Black woman on the Supreme Court, Justice Jackson serves as an inspiration to countless individuals, demonstrating that anything is possible with hard work, dedication, and a commitment to one's goals.
Black people make up 13.4 percent of the United States population, but Black attorneys make up 4.5 percent of lawyers in the United States. From Attorney Macon Bolling Allen, the first Black attorney, to Justice Jackson, Black people have rightfully demanded and took action to be included in the legal profession. Thank you to Justice Jackson for being a part of the thread of historical moments in the tapestry of Black History.
