Question: Dolan v. City of Tigard and Gravel v. United States were both cases in which US court?

Context paragraphs:
Dolan v. United States Postal Service: Dolan v. United States Postal Service, 546 U.S. 481 (2006), was a case decided by the Supreme Court of the United States, involving the extent to which the United States Postal Service has sovereign immunity from lawsuits brought by private individuals under the Federal Tort Claims Act.  The Court ruled that an exception to the FTCA that barred liability for the "negligent transmission of mail" did not apply to a claim for injuries caused when someone tripped over mail left by a USPS employee.  Instead, the exception only applied to damage caused to the mail itself or that resulted from its loss or delay.

Criminal law in the Waite Court: During the tenure of Morrison Waite as Chief Justice of the Supreme Court of the United States (March 4, 1874 through March 23, 1888), the Supreme Court heard an unprecedented volume and frequency of criminal cases.  In just fourteen years, the Court heard 106 criminal cases, almost as many cases as the Supreme Court had heard in the period from its creation to the appointment of Waite as Chief Justice.  Notable cases include "United States v. Cruikshank" (1875), "United States v. Reese" (1875), "Reynolds v. United States" (1878), "Wilkerson v. Utah" (1879), the "Trade-Mark Cases" (1879), "Strauder v. West Virginia" (1880), "Pace v. Alabama" (1883), "United States v. Harris" (1883), "Ex parte Crow Dog" (1883), "Hurtado v. California" (1884), "Clawson v. United States" (1885), "Yick Wo v. Hopkins" (1886), "United States v. Kagama" (1886), "Ker v. Illinois" (1886), and "Mugler v. Kansas" (1887).

Same-sex marriage in the Sixth Circuit: On April 28, 2015, the Supreme Court of the United States heard oral arguments for "Obergefell v. Hodges" (Ohio), which was consolidated with three other same-sex marriage cases from the other states in the Sixth Circuit: "Tanco v. Haslam" (Tennessee), "DeBoer v. Snyder" (Michigan), "Bourke v. Beshear" (Kentucky).  On June 26, 2015 the Supreme Court reversed the Sixth Circuit's decision, paving the way for same-sex marriage to become legal in those states, and setting a precedent for the entire nation.  All four states complied with the ruling the same day it was issued before the mandate was actually issued.  Every state in the circuit had a district court ruling against their states' ban, but they were eventually stayed pending appeal.  The Sixth Circuit consists of Kentucky, Michigan, Ohio, and Tennessee.  On August 6, 2014, the Sixth Circuit heard oral arguments for same-sex marriage cases from each state within the circuit.  On November 6, 2014, the Sixth Circuit in a split 2-1 decision, upheld the states' same-sex marriage bans, reversing the district courts' rulings that struck them down.  The Sixth Circuit was the first and only circuit court since the landmark ruling "United States v. Windsor" to uphold the constitutionality of states' same-sex marriage bans which caused a circuit split.

Dolan v. City of Tigard: Dolan v. City of Tigard, 512 U.S. 374 (1994) , more commonly Dolan v. Tigard, was a United States Supreme Court case.  It was a landmark case regarding the practice of zoning and property rights, and served to establish limits on the ability of cities and other government agencies, to use zoning and land-use regulations to compel property owners to make unrelated public improvements.

Gravel v. United States: Gravel v. United States, 408 U.S. 606 (1972), was a case regarding the protections offered by the Speech or Debate Clause of the United States Constitution.  In the case, the Supreme Court of the United States held that the privileges and immunities of the Constitution's Speech or Debate Clause enjoyed by members of Congress also extend to Congressional aides, but not to activity outside the legislative process.

BedRoc Limited, LLC v. United States: BedRoc Limited, LLC v. United States, 541 U.S. 176 (2004) , is a United States Supreme Court case in which the Court decided sand and gravel are not "valuable minerals" reserved to the United States Government under the Pittman Underground Water Act of 1919.  The Court sided in a 6–3 decision with the petitioner, BedRoc Limited, and reversed the decision of the Ninth Circuit Court.  BedRoc Limited had removed sand and gravel from lands obtained under the Pittman Act, and the United States, the respondent, argued those were reserved to the U.S. Government under that law.

Freedom of movement under United States law: Freedom of movement under United States law is governed primarily by the Privileges and Immunities Clause of the United States Constitution which states, "The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States."  As far back as the circuit court ruling in "Corfield v. Coryell," 6 Fed.  Cas.  546 (1823), freedom of movement has been judicially recognized as a fundamental Constitutional right.  In "Paul v. Virginia," 75 U.S. 168 (1869), the Court defined freedom of movement as "right of free ingress into other States, and egress from them."  However, the Supreme Court did not invest the federal government with the authority to protect freedom of movement.  Under the "privileges and immunities" clause, this authority was given to the states, a position the Court held consistently through the years in cases such as "Ward v. Maryland," 79 U.S. 418 (1871), the "Slaughter-House Cases," 83 U.S. 36 (1873) and "United States v. Harris," 106 U.S. 629 (1883).

Delta Groove Productions: Delta Groove Productions is an American blues record label in Van Nuys, California, United States.  The label was founded by Randy Chortkoff, a producer, concert promoter, and harmonica player who died in May 2015 while awaiting a liver transplant and sentencing on multiple criminal felony fraud charges including bilking investors of over $1,400,000 in a phony movie investment scam.  In 2016, Chortkoff's co-defendant Sam Braslau was sentenced to seven years in federal prison in Lompoc, California.  Co-defendant Stuart Rawitt previously pled guilty and was sentenced to 5 years in federal prison.  Both co-defendants were ordered by the US Court to pay restitution of $1,600,000.  In February 2017, the Chortkoff Estate was ordered by the US Court to pay $153,400 in disgorgement and $12,615 in prejudgment interest in the civil matter with the SEC.

Stephen Halbrook: Stephen P. Halbrook is a Senior Fellow at the Independent Institute and an author and lawyer known for his litigation on behalf of the National Rifle Association.  He has written extensively about the original meanings of the Second Amendment and the Fourteenth Amendment (the latter as applied to Second Amendment rights).  He has argued and won three cases before the US Supreme Court: "Printz v. United States", "United States v. Thompson-Center Arms Company", and "Castillo v. United States".  He has also written briefs in many other cases, including the Supreme Court cases "Small v. United States" (pertaining to the Gun Control Act of 1968) and "McDonald v. Chicago".  In "District of Columbia v. Heller", he wrote a brief on behalf of the majority of both houses of Congress.  More broadly, his decades of research on the Second Amendment contributed to the intellectual foundation of the "Heller" decision.  He has written many books and articles on the topic of gun control, some of which have been cited in Supreme Court opinions ("Heller", "McDonald", "Printz v. United States").  He has testified before congress on multiple occasions.  Halbrook’s most important scholarly contribution, however, was the book "That Every Man Be Armed", originally published in 1986.  The book was the most thorough analysis of the legal history and original intent of the Second Amendment.

Legal Tender Cases: The Legal Tender Cases were a series of United States Supreme Court cases in the latter part of the nineteenth century that affirmed the constitutionality of paper money.  In the 1869 case of "Hepburn v. Griswold", the Court had held that declaring paper notes to be legal tender in payment of debts existing prior to the Legal Tender Act of 1862 violated the United States Constitution.  In the "Legal Tender Cases", the Court overruled "Hepburn", beginning with "Knox v. Lee" and "Parker v. Davis" in 1871, and then "Juilliard v. Greenman" in 1884.
