In Litten v Police (1996) 13 CRNZ 604 (HC), Richard created a landmark decision in which a person in custody who does not understand the legal rights read to him, is entitled to not only a first Bill of Rights warning (Miranda warning) but in certain circumstances a second one. Elias J held, that the breach of the accused's right justified the exclusion of the prosecution's evidence against him.
