Why is the date of a decision important in applying authorities?

• A. Later decisions may overrule or modify earlier holdings; date matters for current authority.
• B. Date has no effect on authority.
• C. Older decisions always control regardless of context.
• D. Only decisions within the same year are binding.

Answer: (A)

In applying authorities, the date of a decision matters because legal rules can change after it’s issued. A ruling sets the law at that moment, but later decisions or legislation can modify, distinguish, or overturn it. If a later case clarifies or reverses the earlier holding, the earlier decision may no longer be the controlling rule for new cases. If nothing later affects it, the decision can remain good law, but you have to check current status to know what actually applies today. That’s why the timing of the decision is essential: it determines whether its holdings are still authoritative. The other statements miss this dynamic—authority isn’t independent of time, and older decisions don’t automatically control in all contexts or only within the same year.
