Not All Evidence, Not All Witnesses Needed (NEN AWN) is a legal principle which states that a court or tribunal may decide a case without requiring all evidence to be presented or all witnesses to be heard. This principle is based on the idea that a court should not be burdened with unnecessary procedures. There are two main types of NEN AWN: 1. Rebut table Presumption: This type of NEN AWN states that a court may presume the truth of certain facts or statements if no contrary evidence is presented, unless the party contesting the presumption can produce sufficient evidence to rebut it. 2. Substantial Compliance: This type of NEN AWN states that a court may decide a case based on the evidence presented, even if it is not the same evidence that would have been presented if all witnesses had been heard or all evidence had been produced. This principle allows courts to make decisions with less evidence, as long as the evidence presented is sufficient to decide the case. NEN AWN is an important legal principle that allows courts to make decisions without having to hear every single witness or review every piece of evidence. This helps to ensure that justice is served while also avoiding unnecessary delays in the judicial process.
