The court may be moved to take judicial notice of any commonly known fact, e.g., that Tuesday regularly follows Monday or that the moon was full at least once during the past 30 days or so. The court may also be moved to take judicial notice of any law that controls the outcome of your case, whether the law is statute, constitutional, or case law. Any commonly known fact about which reasonable people do not dispute. The jurisdiction of a court is its legal authority to act. This is very important.
Different courts have different jurisdictions.
Please take note that every court does not have jurisdiction to hear every kind of case. Some courts are limited to a maximum dollar amount. Other courts cannot hear family matters or lawsuits between parties fighting over property boundaries. If you are sued, make certain the court your opponent selected is the proper court, i.e., that the court you are in actually has jurisdiction over the matter presented by the plaintiff. If you are the plaintiff, make very sure you are in the right court.
