Judicial Notice (F.R.E. 201) is a legal concept that permits a court to accept certain facts as true without requiring proof from either party. This concept is based on the idea that some facts are so well-known and accepted that their truthfulness is not in dispute. Judicial Notice is divided into two categories: mandatory and discretionary. Mandatory Judicial Notice (F.R.E. 201(d)) requires a court to accept certain facts as true without the introduction of evidence. These facts must be capable of accurate and ready determination by resorting to sources whose accuracy cannot reasonably be questioned. Discretionary Judicial Notice (F.R.E. 201(c)) allows a court to accept certain facts as true on its own discretion. These facts must be generally known or capable of accurate and ready determination by resorting to sources whose accuracy cannot reasonably be questioned. In both cases, Judicial Notice (F.R.E. 201) eliminates the need for a party to introduce evidence to prove the fact in question. This helps to streamline the legal process and ensure that the court is aware of facts that are widely accepted.
