Now, a court in the determination of a matter before it enquires into and relies on the relevant facts led by parties before it, draws inferences from such facts and the arguments canvassed by the parties or their counsel. Judicial evidence is the means by which the facts relied upon in taking decisions are proved. Facts are proved by oral testimony of the persons who perceived them, by the production of documents and inspections of things or places. Facts can also be proved by admissions, confessions, judicial notice, presumptions and estoppel. A Judge is free to take Judicial notice of all such facts he is either called upon to or from his general knowledge of such facts or from enquiries made by him on such facts from sources to which it is proper for him to refer.
