In New Zealand, you have a right to go to court and represent yourself; self-representation procures access to the courts. But, whether it provides access to justice is another question.
In Prattley Enterprises Limited v Vero Insurance NZ Limited [2016] NZSC 158 the Supreme Court unanimously confirmed that a signed settlement agreement was binding on the parties, where the insured party asserts it was operating under a mistake over its entitlement under the policy. On appeal from the Court of Appeal, Prattley had (again) sought to set aside the settlement agreement it signed with its insurer Vero, on the basis that both it and Vero entered the settlement under a common mistake as to the correct measure of indemnity under the policy.
The UK Supreme Court has now clarified an uncertain area of law regarding deceit and misrepresentation in the context of settlement agreements, where fraud is suspected: Hayward v Zurich Insurance Company plc [2016] UKSC 48.
