Baker v. Wade 563 F.Supp 1121 (N.D. Tex. 1982), rev'd 769 F.2nd 289 (5th Cir.
 1985) (en banc) cert denied 478 US 1022 (1986) is a federal lawsuit challenging the legality of the sodomy law of the state of Texas.
 Plaintiff Donald Baker contended that the law violated his rights to privacy and equal protection.
 After a victory at trial, an appellate court reversed the lower court's decision and in the wake of its decision in "Bowers v. Hardwick" the Supreme Court of the United States refused to review it.
Denise R. Johnson (born July 13, 1947) is a Vermont attorney and judge.
 She was an Associate Justice of the Vermont Supreme Court from 1990 to 2011, and was the first woman to serve on this court.
 One of Johnson's most significant moments was her opinion in "Baker v. Vermont" in which a majority of the Supreme Court of Vermont ruled the state must establish civil unions for same sex couples.
 Johnson dissented, arguing that the court should have granted the plaintiffs marriage licenses instead.
Michael McConnell and Jack Baker are pioneering advocates of marriage rights for gay couples.
 Jack Baker was a stage name used by Richard John Baker in the 1970s to promote full equality for gay men and women.
 He and Michael McConnell applied in Hennepin County for a license to marry, then appealed its denial to the Minnesota Supreme Court, which dismissed the claim.
 "Under the law at the time (since repealed) governing the [U.S.] Supreme Court’s jurisdiction over appeals from state-court decisions, "Baker v. Nelson" reached the justices as a mandatory appeal."
 The State argued that the marriage license issued previously in Blue Earth County proved that the "Questions Raised by This Appeal Are Moot."
Mallinckrodt, Inc. v. Medipart, Inc., 976 F.2d 700 (Fed.
 Cir.
 1992), is a decision of the United States Court of Appeals for the Federal Circuit, in which the court appeared to overrule or drastically limit many years of U.S. Supreme Court precedent affirming the patent exhaustion doctrine, for example in "Bauer & Cie. v. O'Donnell".
In the United States, same-sex marriage is legal in all states, Washington, D.C., as well as all U.S. territories except American Samoa, but not on all Native American tribal lands, since June 26, 2015, when the United States Supreme Court ruled in "Obergefell v. Hodges" that state-level bans on same-sex marriage are unconstitutional.
 The court ruled that the denial of marriage licenses to same-sex couples and the refusal to recognize those marriages performed in other jurisdictions violates the Due Process and the Equal Protection clauses of the Fourteenth Amendment of the United States Constitution.
 The ruling overturned a 1972 precedent, "Baker v. Nelson".
 Just prior to the Supreme Court's ruling in 2015, same-sex marriage was legal in many but not all U.S. jurisdictions.
Obergefell v. Hodges, 576 U.S. ___ (2015) ( ), is a landmark civil rights case in which the United States Supreme Court ruled that the fundamental right to marry is guaranteed to same-sex couples by both the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution in a 5–4 decision.
The Burger Court refers to the Supreme Court of the United States from 1969 to 1986, when Warren Burger served as Chief Justice of the United States.
 Burger succeeded Earl Warren as Chief Justice after the latter's retirement, and Burger served as Chief Justice until his retirement, at which point William Rehnquist was nominated and confirmed as Burger's replacement.
 The Burger Court has been described as a "transitional" court which continued the liberal legacy of the Warren Court but transitioned into the more conservative Rehnquist Court.
 Burger remained a symbol of the conservative "retrenchment" promised by President Richard Nixon in the 1968 election, but Burger was often overshadowed by the liberal William Brennan and the more conservative William Rehnquist.
 The Burger Court had a less generous interpretation of the protections offered by the Fourth Amendment and the Fifth Amendment than those of the Warren Court, but the Burger Court did not overrule any of the major precedents set by the Warren Court.
Michigan v. Long, 463 U.S. 1032 (1983), was a decision by the United States Supreme Court that extended "Terry v. Ohio", 392 U.S. 1 (1968) to allow searches of car compartments during a stop with "reasonable suspicion".
 The case also clarified and narrowed the extent of adequate and independent state ground, allowing U.S. Supreme Court review of state supreme court decisions unless they explicitly appealed to state laws.
Richard John Baker v. Gerald R. Nelson, 291 Minn. 310, 191 N.W.2d 185 (1971) is a case in which the Minnesota Supreme Court ruled that a state law limiting marriage to persons of the opposite sex did not violate the U.S. Constitution.
 Baker appealed, and on October 10, 1972, the United States Supreme Court dismissed the appeal "for want of a substantial federal question."
 Because the case came to the U.S. Supreme Court through mandatory appellate review (not "certiorari"), the dismissal constituted a decision on the merits and established "Baker v. Nelson" as precedent, though the extent of its precedential effect had been subject to debate.
 In May 2013, Minnesota legalized same-sex marriage and it took effect on August 1, 2013.
 Subsequently, on June 26, 2015, the U.S. Supreme Court explicitly overruled "Baker" in "Obergefell v. Hodges" making same-sex marriage legal nationwide.
V.L. v. E.L., 577 U.S. ___ (2016) , is a case decided by the Supreme Court of the United States concerning the adoption rights of same-sex couples.
 In 2007, a Georgia Superior Court granted adoption rights to V.L., the partner of E.L., the woman who gave birth to their three children.
 However, after moving back to Alabama, the couple split up.
 E.L. tried to block V.L. from seeing the children, but V.L. filed a lawsuit seeking visitation and other parental rights.
 On September 18, 2015, the Supreme Court of Alabama ruled that the state did not have to recognize the adoption judgment, saying that the Georgia court misapplied its own state law.
 The court voided the recognition of the adoption judgment in Alabama.
 V.L. petitioned the United States Supreme Court to stay the ruling during her appeal and allow her to see her children.
 On December 14, 2015, the Supreme Court stayed the ruling pending their action on a petition for a writ of certiorari filed by V.L. On March 7, 2016, the Supreme Court of the United States reversed the decision of the Alabama Supreme Court by per curiam summary disposition.
