Opposing counsel was called as a witness for examination in the American scopes trial.
Is such a practice allowed in English trial practice? Concerns here that come to mind:
Must a witness have previously filed a witness statement per se if they are to be called to the stand? Opposing counsel nonetheless will be physically present and available at the trial, AND will have drafted/submitted case presentation or argument outlines to the court on which they may be questioned.
If not, are there any other techniques which may be employed to be able to achieve this sort of direct dialogue wherein the coherence/integrity of the opposing counsel’s legal arguments may be challenged?
