22. Privilege

This chapter discusses several well-established principles whereby relevant evidence is excluded because of extrinsic considerations which outweigh the value that the evidence would have at trial. Three types of privilege are considered: (i) the privilege against self-incrimination (including statutory withdrawal of the privilege, compatibility with Article 6 of the European Convention on Human Rights, the compulsory production of pre-existing documents and materials, and substituted protection); (ii) legal professional privilege, which enables a client to protect the confidentiality of (a) communications between him and his lawyer made for the purpose of obtaining and giving legal advice (known as ‘legal advice privilege’) and (b) communications between him or his lawyer and third parties for the dominant purpose of preparation for pending or contemplated litigation (known as ‘litigation privilege’); and (iii) ‘without prejudice’ privilege, which enables settlement negotiations to be conducted without fear of proposed concessions being used in evidence at trial as admissions.
