Practical privilege
The New Zealand legal system is a common law system, based on the English system of justice. As a result, New Zealand, like England, Australia, Canada and the USA, adopts an adversarial court process. What this means is that the Courts are reliant on the parties to produce evidence and argue in favour of a particular version of events. Based on this evidence and argument from counsel, the Court will make a decision as to which party is right and which is wrong.
