In which case would a court not take judicial notice?

A court generally takes judicial notice of facts that are not subject to reasonable dispute because they are either generally known within the jurisdiction or can be accurately and readily determined from reliable sources.

In the case of an individual's birthdate, although it is a factual statement, it is not a fact that is universally known or easily verified without evidence. While some birthdates might be common knowledge (e.g., public figures or significant historical individuals), the birthdate of a private individual is not something that can be readily known or verified unless documented in a reliable source such as a birth certificate. This uncertainty regarding the verification of specific birthdates means a court would typically not take judicial notice of it.

In contrast, facts like whether it rained on a certain date or the date of Independence Day are either widely known or can be verified through public records and sources. The fact regarding the defendant's frivolous lawsuits may also be subject to judicial notice depending on public records or court filings. Thus, the birthdate stands out as a fact that does not meet the criteria for judicial notice.
