If the oath has never been changed, it follows that judges have not only never been sworn to support any statutes whatever of the king, or of parliament, but that, for five hundred years past, they actually have been sworn to treat as invalid all statutes that were contrary to the common law.
SECTION VI. The Coronation Oath.
That the legislation of the king was of no authority over a jury, is further proved by the oath taken by the kings at their coronation. This oath seems to have been substantially the same, from the time of the Saxon kings, down to the seventeenth century, as will be seen from the authorities hereafter given.
The purport of the oath is, that the king swears to maintain the law of the land that is, the common law. In other words, he swears "to concede and preserve to the English people the laws and customs conceded to them by the ancient, just, and pious English kings, * * and especially the laws, customs, and liberties conceded to the clergy and people by the illustrious king Edward;" * * and "the just laws and customs which the common people have chosen, (quas vulgus elegit)."
These are the same laws and customs which were called by the general name of "the law of the land," or "the common law," and, with some slight additions, were embodied in Magna Carta.
This oath not only forbids the king to enact any statutes contrary to the common law, but it proves that his statutes could be of no authority over the consciences of a jury; since, as has already been sufficiently shown, it was one part of this very common law itself, that is, of the ancient "laws, customs, and liberties," mentioned in the oath, that juries should judge of all questions that came before them, according to their own consciences, independently of the legislation of the king.
It was impossible that this right of the jury could subsist consistently with any right, on the part of the king, to impose any authoritative legislation upon them. His oath, therefore, to maintain the law of the land, or the ancient "laws, customs, and liberties," was equivalent to an oath that he would never assume to impose laws upon juries, as imperative rules of decision, or take from them the right to try all cases according to their own consciences. It is also an admission that he had no constitutional power to do so, if he should ever desire it. This oath, then, is conclusive proof that his legislation was of no authority with a jury, and that they were under no obligation whatever to enforce it, unless it coincided with their own ideas of justice.
The ancient coronation oath is printed with the
Statutes of the Realm, vol. i., p. 168, and is as follows: [31]
