While however I think that there are occasional cases where the statement of facts may be dispensed with, I disagree with those who say that there is no statement of facts when the accused simply denies the charge. This opinion is shared by Cornelius Celsus who holds that most cases of murder and all of bribery and extortion fall into this class.
For he thinks that the only statement of facts is that which gives a general account of the charge before the court. Yet he himself acknowledges that Cicero employed the statement of facts in his defence of Rabirius Postumus, in spite of the fact that Cicero denies that any money came into the hands of Rabirius (and this was the question at issue) and gives no explanations relating to the actual charge in his statement of facts.
For my part I follow the very highest authorities in holding that there are two forms of statement of facts in forensic speeches, the one expounding the facts of the case itself, the other setting forth facts which have a bearing on the case.
