Key Terms to Review (28)

Appellate courts: Appellate courts are judicial bodies that review the decisions made by lower courts, primarily to ensure the correct application of law and to address potential legal errors. These courts do not conduct trials or hear new evidence; instead, they focus on examining the record of the lower court's proceedings and the arguments presented by both sides. Their role is crucial in maintaining the integrity of the judicial system by providing a mechanism for correcting mistakes and ensuring that justice is served.
Arraignment: Arraignment is a formal court proceeding in which a defendant is brought before a judge to hear the charges against them and enter a plea. This step is crucial as it marks the beginning of the criminal trial process, allowing the defendant to understand the allegations and make informed decisions regarding their defense. During arraignment, the defendant may also be informed of their rights, and bail may be discussed, setting the stage for subsequent court proceedings.
Brown v. Board of Education: Brown v. Board of Education was a landmark 1954 Supreme Court case that declared state laws establishing separate public schools for black and white students unconstitutional, effectively overturning the 'separate but equal' doctrine established by Plessy v. Ferguson. This case was pivotal in the Civil Rights Movement, as it laid the groundwork for the desegregation of schools and challenged systemic racial discrimination in the United States.
Case backlog: A case backlog refers to the accumulation of cases that are awaiting resolution within the judicial system. This situation occurs when there are more cases being filed than can be processed in a timely manner, leading to delays in legal proceedings and a strain on court resources. The presence of a case backlog can significantly impact the efficiency of the court system and the delivery of justice.
Court efficiency: Court efficiency refers to the ability of the judicial system to process cases in a timely manner while ensuring justice is served. It involves optimizing resources, reducing delays, and minimizing backlogs, which are crucial for maintaining public trust in the legal system and ensuring that individuals receive fair treatment in a reasonable time frame.

Double jeopardy: Double jeopardy is a legal principle that prevents an individual from being tried twice for the same offense after either a conviction or an acquittal. This principle is rooted in the Fifth Amendment of the U.S. Constitution, emphasizing the protection of individuals from the stress and stigma of multiple trials for the same crime. Double jeopardy also relates to the broader court structure and the roles of key players, ensuring fairness in legal proceedings and reinforcing the finality of judicial decisions.
Due Process: Due process refers to the legal requirement that the state must respect all legal rights owed to a person.

They have the authority to hear a wide range of civil and criminal cases, including those involving federal laws, and are where judges and juries evaluate evidence and make rulings.
Voir dire: Voir dire is the legal process of questioning potential jurors to determine their suitability to serve on a jury for a specific trial. This process is crucial as it helps to ensure that jurors can remain impartial and make decisions based on the evidence presented during the trial.
