Discuss the emerging trends in evidence law.

Evidence — the material of proof: the facts (and the documents, objects and testimony carrying them) from which the court infers the existence of the facts in issue. The word's root (evidere — "to show clearly"): the showing of the truth. Evidence law — the rules governing what may be shown, how, and with what effect: the admissibility (the gatekeeping), the examination (the process), the weight (the evaluation). The law's home in Nepal: the Evidence Act 2031(1974) — the principal statute (the civil-and-criminal proof's code) — plus the procedural codes' machinery (the Civil-and-Criminal Procedure Codes 2074) and the specialised rules (the electronic, the forensic — U4.3's world).
