Critical discourse analysis (CDA) has become a very influential interdisciplinaryapproach, which views a discourse as a form of social practice. Antipoligamydiscourse, as a social practice persisted for a long time ago in Indonesia, offerschalenging discussions in the perspective of CDA. Teun van Dijk, as one of thepioneers of CDA, articulates ideology as the basis of the social representationsof groups. Furthermore, he advocates a sociocognitive interface between socialstructures and discourse structures. Within these views, whenever social groups,including the producers of antipoligamy texts, voice their ideas and feelings,their ideology come up apparently or, otherwise, lies behind language. Thispaper is an attempt to explain how women formulate their beliefs into a jointstatement: by using what ideological discourse production strategies they sharetheir ideology to public. A Joint Statement issued in December 2006, whichcontains a broad definition of poligamy in negative sense, in fact representsnegative other-representation strategy used by its producer.
