Article Two of the United States Constitution establishes the executive branch of the federal government, which carries out and enforces federal laws. Article Two vests the power of the executive branch in the office of the president of the United States, lays out the procedures for electing and removing the president, and establishes the president's powers and responsibilities.
Article Six of the United States Constitution establishes the laws and treaties of the United States made in accordance with it as the supreme law of the land, forbids a religious test as a requirement for holding a governmental position, and holds the United States under the Constitution responsible for debts incurred by the United States under the Articles of Confederation.
Ex parte Milligan, 71 U.S. 2 (1866), is a landmark decision of the U.S. Supreme Court that ruled that the use of military tribunals to try civilians when civil courts are operating is unconstitutional. In this particular case, the Court was unwilling to give President Abraham Lincoln's administration the power of military commission jurisdiction, part of the administration's controversial plan to deal with Union dissenters during the American Civil War. Justice David Davis, who delivered the majority opinion, stated that "martial rule can never exist when the courts are open" and confined martial law to areas of "military operations, where war really prevails", and when it was a necessity to provide a substitute for a civil authority that had been overthrown. Chief Justice Salmon P. Chase and three associate justices filed a separate opinion concurring with the majority in the judgment, but asserting that Congress had the power to authorize a military commission, although it had not done so in Milligan's case.
United States v. Klein, 80 U.S. 128 (1871), was a landmark United States Supreme Court case stemming from the American Civil War (1861–1865).
A bill of attainder is an act of a legislature declaring a person, or a group of people, guilty of some crime, and punishing them, often without a trial. As with attainder resulting from the normal judicial process, the effect of such a bill is to nullify the targeted person's civil rights, most notably the right to own property, the right to a title of nobility, and, in at least the original usage, the right to life itself.
Augustus Hill Garland was an American lawyer and Democratic politician from Arkansas, who initially opposed Arkansas' secession from the United States, but later served in both houses of the Congress of the Confederate States and the United States Senate, as well as becoming the 11th governor of Arkansas (1874–1877) and the 38th attorney general of the United States (1885–1889).
A number of cases were tried before the Supreme Court of the United States during the period of the American Civil War. These cases focused on wartime civil liberties, and the ability of the various branches of the government to alter them. The following cases were among the most significant.
Separation of powers is a political doctrine originating in the writings of Charles de Secondat, Baron de Montesquieu in The Spirit of the Laws, in which he argued for a constitutional government with three separate branches, each of which would have defined abilities to check the powers of the others. This philosophy heavily influenced the drafting of the United States Constitution, according to which the Legislative, Executive, and Judicial branches of the United States government are kept distinct in order to prevent abuse of power. The American form of separation of powers is associated with a system of checks and balances.
The Ironclad Oath was an oath promoted by Radical Republicans that required federal employees, lawyers, and federal elected officials to swear upon entry of office that they had never supported the Confederacy. The first such law adopted by Congress was in 1862 which attempted to make the oath a requirement for the incoming members of the 38th United States Congress to take the oath. In 1863, President Abraham Lincoln proposed the Ten percent plan, which proposed that a state in rebellion could be reintegrated if a similar oath, with an additional pledge to abide by the nationwide abolition of slavery, was taken by 10% of its voters. Congress then attempted to raise this to 51% of voters in the Wade–Davis Bill of 1864, which Lincoln pocket vetoed on the grounds that is was too harsh. After the assassination of Lincoln in 1865, his successor, Andrew Johnson, opposed the oath altogether. Given the temporary disenfranchisement of the numerous Confederate veterans and local civic leaders, a new Republican biracial coalition came to power in the eleven Southern states during Reconstruction. Southern conservative Democrats were angered to have been disenfranchised.
Lambdin Purdy Milligan was an American lawyer and farmer who was the subject of Ex parte Milligan 71 U.S. 2 (1866), a landmark case by the Supreme Court of the United States. He was known for his extreme opinions on states' rights and his opposition to the Lincoln administration's conduct of the American Civil War.
Calder v. Bull, 3 U.S. 386 (1798), is a United States Supreme Court case in which the Court decided four important points of constitutional law.
Garner v. Board of Public Works, 341 U.S. 716 (1951), is a ruling by the United States Supreme Court which held that a municipal loyalty oath which required an oath and affidavit about one's beliefs and actions for the previous five years and which was enacted more than five years previous is not an ex post facto law nor a bill of attainder.
United States v. Lovett, 328 U.S. 303 (1946), was a United States Supreme Court case in which the Court held that Congress may not forbid the payment of a salary to a specific individual, as it would constitute an unconstitutional bill of attainder.
United States v. More, 7 U.S. 159 (1805), was a United States Supreme Court case in which the Court held that it had no jurisdiction to hear appeals from criminal cases in the circuit courts by writs of error. Relying on the Exceptions Clause, More held that Congress's enumerated grants of appellate jurisdiction to the Court operated as an exercise of Congress's power to eliminate all other forms of appellate jurisdiction.
The Chase Court (1864–1873) issued thirty-five opinions in criminal cases over nine years, at a significantly higher rate than the Marshall Court or Taney Court before it. Notable such cases include Ex parte Milligan (1866), Pervear v. Massachusetts (1866), Ex parte McCardle, Ex parte Yerger (1868), and United States v. Kirby (1868).
The president of the United States is authorized by the U.S. Constitution to grant a pardon for a federal crime. The other forms of the clemency power of the president are commutation of sentence, remission of fine or restitution, and reprieve. A person may decide not to accept a pardon, in which case it does not take effect, according to a Supreme Court majority opinion in Burdick v. United States. In 2021, the 10th Circuit ruled that acceptance of a pardon does not constitute a legal confession of guilt, recognizing the Supreme Court's earlier language as dicta.
On August 25, 2017, President Donald Trump pardoned Joe Arpaio for criminal contempt of court, a misdemeanor. Arpaio had been convicted of the crime two months earlier for disobeying a federal judge's order to stop racial profiling in detaining "individuals suspected of being in the U.S. illegally". The pardon covered Arpaio's conviction and "any other offenses under Chapter 21 of Title 18, United States Code that might arise, or be charged, in connection with Melendres v. Arpaio." The official White House statement announcing the grant of clemency described Arpaio as a "worthy candidate" having served the nation for more than fifty years "protecting the public from the scourges of crime and illegal immigration."
Ex parte Grossman, 267 U.S. 87 (1925), was a US Supreme Court case that held that the US President may pardon criminal contempt of court. Grossman had been convicted of criminal contempt but was pardoned by the President. The district court subsequently sent him back to prison.
