The John Philip Sousa Middle School, formerly the John Philip Sousa Junior High School, is a public school located at 3650 Ely Place in SE area of Washington, D.C. Located in the city's Fort Dupont neighborhood, it serves grades 6-8.
 Its school building, built in 1950, was the scene of civil rights action not long after its construction.
 Twelve black students were denied admission to all-white school.
 This action was eventually overturned in the landmark 1954 Supreme Court decision in "Bolling v. Sharpe", which made segregated public schools illegal in the District of Columbia.
 The defeat of the legal doctrine "separate but equal" marked an early victory in the modern Civil Rights Movement.
 The school was declared a National Historic Landmark in 2001 for its role in this action.
Bolling v. Sharpe, 347 U.S. 497 (1954), is a landmark United States Supreme Court case which deals with civil rights, specifically, segregation in the District of Columbia's public schools.
 Originally argued on December 10–11, 1952, a year before "Brown v. Board of Education", 347 U.S. 483 (1954), "Bolling" was reargued on December 8 and 9, 1953, and was unanimously decided on May 17, 1954, the same day as "Brown."
 The "Bolling" decision was supplemented in 1955 with the second "Brown" opinion, which ordered desegregation "with all deliberate speed."
 "Bolling" did not address school desegregation in the context of the Fourteenth Amendment's Equal Protection Clause, which applies only to the states, but held that school segregation was unconstitutional under the Due Process Clause of the Fifth Amendment to the United States Constitution.
 In "Bolling," the Court observed that the Fifth Amendment to the United States Constitution lacked an Equal Protection Clause, as in the Fourteenth Amendment to the United States Constitution.
 The Court held, however, that the concepts of Equal Protection and Due Process are not mutually exclusive.
George Edward Chalmers Hayes (July 1, 1894 – December 20, 1968) was a Washington, DC lawyer who defended Annie Lee Moss on March 11, 1954.
 He was the lead attorney in "Bolling v. Sharpe" (1954).
 In 1955 he became the first African American to serve on the District of Columbia Public Utilities Commission.
LGBT (also seen as LGBTQ) stands for lesbian, gay, bisexual, transgender, and/or queer.
 The LGBT community did not receive societal recognition until the historical marking of the Stonewall Riots in 1969 in New York at Stonewall Inn.
 The Stonewall riots brought domestic and global attention to the lesbian and gay community.
 Proceeding Stonewall, Romer v. Evans vastly impacted the trajectory of the LGBT community.
 Ruling in favor of Romer, Justice Kennedy asserted in the case commentary that Colorado's state constitutional amendment "bore no purpose other than to burden LGB persons".
The T-3 case, formally United States v Escamilla, 467 F.2d 341 (1972), was a series of legal disputes following a death on the Arctic ice island T-3 in July 1970.
 In a dispute over some raisin wine, one member of the crew of a research station was alleged to have shot and killed another.
 Both men were Americans, but the case took place outside American territorial waters, and the case raised a number of questions on the jurisdiction of criminal law in special circumstances.
 After a trial, appeal, and retrial, the defendant was acquitted, but the matter of jurisdiction was not settled until American law was revised in 1984.
The Anderson case took place in Canada West from 1860 to 1861.
 The case dealt with whether or not to extradite an escaped slave to the United States on the charge of murder.
 The majority of the presiding judges who handled the case agreed that there was sufficient evidence to prove criminality of the extraditable offence.
 The decision was based upon the terms laid out in Article X of the Webster–Ashburton Treaty of 1842.
 Anderson was released, however, on a technicality.
Romer v. Evans, 517 U.S. 620 (1996) , is a landmark United States Supreme Court case dealing with sexual orientation and state laws.
 It was the first Supreme Court case to address gay rights since "Bowers v. Hardwick" (1986), when the Court had held that laws criminalizing sodomy were constitutional.
The first Presidential debate in Argentina took place during the 2015 presidential elections.
 There were proposals for doing so in the previous elections, but were refused by the candidates that were ahead in the polls.
 A controversial case took place in 1989, when Carlos Menem refused at the last moment to attend the debate with Eduardo Angeloz set by Bernardo Neustadt.
 The production then held a "debate" between Angeloz and an empty chair.
Hobson v. Hansen, 269 F. Supp.
 401 (D.D.C. 1967), was a federal court case filed by civil rights activist Julius W. Hobson against Superintendent Carl F. Hansen and the District of Columbia’s Board of Education on the charge that the current educational system deprived blacks and the poor of their right to equal educational opportunities relative to their white and affluent counterparts, on account of race and socioeconomic status.
 Having established "de jure" segregation unconstitutional in "Bolling v. Sharpe" (1954), the federal court addressed questions of "de facto" segregation in D.C. schools, seen in the trends that survived legal desegregation, in "Hobson v. Hansen".
 Judge J. Skelly Wright’s decision, in favor of the plaintiffs, sought to remedy the re-segregation or "de facto" segregation enforced by the educational policies, including tracking and optional-transfer zones, adopted by the Board of Education in an attempt to accommodate the consequences of the shift to integrated schools in the aftermath of "Bolling", and within the wider context of emerging racially and socioeconomically rigid residential patterns.
Edmonson v. Leesville Concrete Company, 500 U.S. 614 (1991) , was a United States Supreme Court case which held that peremptory challenges may not be used to exclude jurors on the basis of race in civil trials.
 "Edmonson" extended the court's similar decision in "Batson v. Kentucky" (1986), a criminal case.
 The Court applied the equal protection component of the Due Process Clause of the Fifth Amendment, as determined in "Bolling v. Sharpe" (1954), in finding that such race-based challenges violated the Constitution.
