(1) In re-organizing machinery for the suppression and punishment of crime by the Assizes of Clarendon and Northampton, he established the general principle that criminal trials should (in the normal case) begin with formal indictment of the accused by a representative body of neighbours sworn to speak the truth.[234] This was merely a systematic enforcement of one of the many forms of _inquisitio_ already in use; from that date onwards the practice so established has been followed in England. Criminal prosecution cannot be begun on mere suspicion or irresponsible complaints. The jury of accusation (or presentment) may be said to have been instituted in 1166, and has continued in use ever since, passing by an unbroken course of development into the grand jury of the present day.[235] ----- Footnote 234: See Pollock and Maitland, I. 131. It was part of Henry’s policy to substitute indictment by a representative jury for the older appeal by the wronged individual or his surviving relatives. The older procedure, however, was not completely abolished though looked upon with disfavour. Its continuance and also its unpopularity may both be traced in chapter 54 of Magna Carta. See _infra_. Footnote 235: Chapter 38 of Magna Carta, according to a plausible interpretation of an admittedly obscure passage, seems to insist on the necessity of such an accusation by the jury:—“_non ... sine testibus fidelibus ad hoc inductis_.” (2) By insisting that the ordeal was the only adequate test of an accused man’s guilt or innocence, Henry unconsciously prepared the way for a second form of jury. When the fourth Lateran Council in the very year of Magna Carta forbade priests to countenance ordeal by their presence or blessing, a death-blow was really dealt to that form of procedure or “test,” since it depended for its authority on superstition. A canon of the Church had thus suddenly struck away the pivot on which Henry had made his entire criminal system to revolve. Some substitute required urgently to be devised. It was to supply this that the petty jury (or its rude antecedent) came into existence. The man who had been publicly accused as _presumably_ guilty by the voice of his neighbours, was asked if he was willing to stand or fall by a further and final reference to the oath of a second jury of neighbours. This second verdict, then, was the new “test” or “law” substituted, if the accused man agreed, for his old right of proving himself innocent by the ordeal. By obscure steps, on which those best entitled to speak with authority are not yet agreed, this jury, giving a second and final verdict, gradually developed into the criminal jury of twelve, the petty jury of to-day, the characteristics of which are well known and which has had so important an influence on the development of constitutional liberties in England, and even, it is said, on the national character.
