ABSTRACT
This paper builds a practical method of analyzing cross-examination dialogues by using tools adapted from formal dialectic and artificial intelligence to show how an argumentation model can shed new light on our understanding of actual cases of cross-examination in the common law courts. This is done by illustrating how the model brings out certain precise formal features of argumentative cross-examinations, which would otherwise be hidden from view. Cross-examination dialogue is further discussed in relation to ancient and contemporary approaches to formal dialectics.

Notes
1. Some convention is needed to enable the reader to distinguish between the moves of the one party from those of the other in complex examples. The convention is here with adopted of consistently designating the Questioner (the more powerful party) as she (her) and the Answerer as he (him).
2. The reader needs to be warned that the term “conflict map” from dispute resolution (Wehr, Citation1979) refers to something different from a conflict diagram in the sense of the term defined in this paper.
