A more thorough explanation:

Definition: A solemn occasion is a serious and unusual circumstance in which the supreme court is constitutionally permitted to render advisory opinions to the remaining branches of government. This happens when the legislature doubts the legality of proposed legislation and a determination must be made to allow the legislature to exercise its functions.

Some factors that have been considered in determining whether a solemn occasion exists include:

• Whether an important question of law is presented
• Whether the question is urgent
• Whether the matter is ripe for an opinion
• Whether the court has enough time to consider the question

For example, if a state legislature is considering passing a law that may be unconstitutional, they may ask the supreme court for an advisory opinion. This would be considered a solemn occasion because it is a serious matter that requires the court's expertise to ensure that the law is legal and constitutional.

Another example could be if there is a dispute between two branches of government over their respective powers. The supreme court may be asked to provide an advisory opinion to help resolve the dispute. This would also be considered a solemn occasion because it is a serious matter that requires the court's guidance to ensure that the government functions properly.
