Gay rights: Oncale v. Sundowner Offshore Services, Inc.: The Supreme Court of the United States rules that federal laws banning on-the-job sexual harassment also apply when both parties are the same sex.

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) rights in the United States have developed over time, with public opinion and jurisprudence changing significantly since the late 1980s. Lesbian, gay and bisexual rights are considered advanced. Even though strong protections for same-sex couples remain in place, the rights of transgender people have faced significant erosion since the beginning of Donald Trump's second presidency.

Oncale v. Sundowner Offshore Services, 523 U.S. 75 (1998), is a landmark decision of the US Supreme Court. The case arose out of a suit for sex discrimination by a male oil-rig worker, who claimed that he was repeatedly subjected to sexual harassment by his male co-workers with the acquiescence of his employer. The Court held that the protection of Title VII of the Civil Rights Act of 1964 against workplace discrimination "because of... sex" applied to harassment in the workplace between members of the same sex.

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U.S. federal court cases, and over state court cases that turn on questions of U.S. constitutional or federal law. It also has original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party." In 1803, the court asserted itself the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution via the landmark case Marbury v. Madison. It is also able to strike down presidential directives for violating either the Constitution or statutory law.

Sexual harassment is a type of harassment based on the sex or gender of a victim. It can involve offensive sexist or sexual behavior, verbal or physical actions, up to bribery, coercion, and assault. Harassment may be explicit or implicit, with some examples including making unwanted sexually colored remarks, actions that insult and degrade by gender, showing pornography, demanding or requesting sexual favors, offensive sexual advances, and any other unwelcome physical, verbal, or non-verbal conduct based on sex. Sexual harassment includes a range of actions from verbal transgressions to sexual abuse or assault. Harassment can occur in many different social settings such as the workplace, the home, school, or religious institutions. Harassers or victims can be of any gender.
