This chapter, first published in Japanese, outlines the field of ‘forensic linguistics’ [as at 2001]. It contrasts the forensic linguistic approach to applying linguistics in legal contexts with a different tradition of analysis: that usually known as Critical Discourse Analysis and/or as Critical Legal Studies. The author examines ‘meaning’ issues in particular, as a way of showing how treatment of specific interpretive questions exposes problematic assumptions underpinning the notion of linguistic expertise. The chapter concludes with a suggestion that, in a period of rapidly changing communication technologies and formats, notions of professional authority in respect of language and meaning may need to be reconsidered
