The document discusses the concept of burden of proof in legal cases. It distinguishes between two types of burden:
1) Persuasive/legal burden, which remains with the party asserting a claim. For criminal cases this means the prosecution must prove guilt beyond reasonable doubt.
2) Evidential/evidentiary burden, which can shift between the parties as evidence is presented. The party with the evidential burden must introduce evidence or risk losing the case. Malaysian law also discusses when the burden of proof lies, how it can be discharged, and exceptions.
