Cross-examination is the process of elucidating the truth through the examination of the contested information by adversary attorneys. The best example of cross- examination is the examination of witnesses. Each attorney questions the witness in turn, and each is allowed to requestion the witness on matters brought out by subsequent questioners. This may take a few minutes or several weeks, depending on the complexity of the testimony. In theory, this relentless questioning eventually flushes out the truth. This theory, however, is predicated on the assumption that the adversaries are sufficiently well versed in the technicalities of the witness’s testimony to recognize the truth when it makes an appearance. In practice, cross- examination of witnesses frequently illuminates little more than the relative acting skills of the examining attorneys and the witness.
