Final answer:
The justices hold a private conference twice a week during periods when the Supreme Court is in session for oral arguments, and once a week when it is not, to discuss the cases and deliberate on their decisions.
Step-by-step explanation:
The justices of the Supreme Court meet in a closed conference twice a week when the court is hearing oral arguments. During these private conferences, they discuss cases, take initial votes, and the Chief Justice speaks first, followed by the other justices in order of seniority. This is a time for them to convey their views on the cases and deliberate on the matters before them. Following the conclusion of oral arguments, the justices engage in discussions that are foundational to their decision-making process.
When the Court is not in session, which entails periods outside of the typical Monday through Wednesday hearings from October to April, the justices meet for conference once a week. The justices' preparation includes reading briefs and writing opinions, with certiorari petitions also being a significant focus of their conferences. The court decisions are ultimately announced publicly before the Court's term ends.
