Final answer:
The best description for creating Supreme Court briefs is that they typically reference legal precedents, with attorneys presenting arguments influenced by past court decisions and relevant laws. Amicus curiae briefs may also serve to provide a broader perspective on the case's implications.
Step-by-step explanation:
The statement that best describes the missing content about how Supreme Court briefs are created is that briefs almost always refer to legal precedents, or the past decisions made by courts in similar cases.
During the Supreme Court proceedings, after the Court agrees to hear a case, attorneys submit briefs from both sides. These briefs argue their client's position, often citing precedents and interpreting the Constitution, the Bill of Rights, or federal laws in a manner that supports their case.
Amicus curiae briefs are also submitted by third parties who have a strong interest in the case's outcome, to present additional arguments and insights.
Stare decisis, a legal principle, ensures the consistency of the judicial system by relying on precedents from past decisions. However, new precedents can be established when cases bring forth unique aspects that the court must consider.
