Judicial Notice (F.R.E. 201) is the legal principle that courts can accept certain facts as true without the need for any additional evidence. This allows courts to save time and resources, as they do not need to consider the evidence presented by either party to make a decision. Judicial Notice (F.R.E. 201) is often used for facts that are so well known or indisputable that there is no need for additional evidence. There are two types of Judicial Notice (F.R.E. 201): mandatory and discretionary. Mandatory Judicial Notice (F.R.E. 201) is when a court is required to take notice of a fact without any additional evidence. This type of notice is typically used for facts that are so well established that they are considered indisputable. Discretionary Judicial Notice (F.R.E. 201) is when a court may, but is not required to, take notice of a fact without any additional evidence. This type of notice is typically used for facts that are not so well established, but are still considered reliable.
