[1] But it is not likely that the losing party was subjected to an amercement as a matter of course, but only in those cases where the injustice of his cause was so evident as to make him inexcusable in bringing it before the courts. All the freeholders were required to attend the courts, that they might serve as jurors and witnesses, and do any other service that could legally be required of them; and their attendance was paid for by the state. In other words, their attendance and service at the courts were part of the rents which they paid the state for their lands. The freeholders, who were thus required always to attendthe courts, were doubtless the only witnesses who were usually required in civil causes. This was owing to the fact that, in those days, when the people at large could neither write nor read, few contracts were put in writing. The expedient adopted for proving contracts, was that of making them in the presence of witnesses, who could afterwards testify to the transactions. Most contracts in regard to lands were made at the courts, in the presence of the freeholders there assembled. [2] In the king's courts it was specially provided by Magna Carta that "justice and right" should not be "sold;" that is, that the king should take nothing from the parties for administering justice. The oath of a party to the justice of his cause was all that was necessary to entitle him to the benefit of the courts free of all expense; (except the risk of being amerced after the trial, in case the jury should think he deserved it. [3]) This principle of the free administration of justice connects itself necessarily with the trial by jury, because a jury could not rightfully give judgment against any man, in either a civil or criminal case, if they had any reason to suppose he had been unable to procure his witnesses.
