1. AND, first, the courts of common law have the superintendency over these courts; to keep them within their jurisdictions, to determine wherein they exceed them, to restrain and prohibit such excess, and (in case of contumacy) to punish the officer who executes, and in some cases the judge who enforces, the sentence so declared to be illegal. 2. THE common law has reserved to itself the exposition of all such acts of parliament, as concern either the extent of these courts or the matters depending before them. And therefore if these courts either refuse to allow these acts of parliament, or will expound them in any other sense than what the common law puts upon them, the king's courts at Westminster will grant prohibitions to restrain and control them. 3. AN appeal lies from all these courts to the king, in the last resort; which proves that the jurisdiction exercised in them is derived from the crown of England, and not from any foreign potentate, or intrinsic authority of their own.--And, from these three strong marks and ensigns of superiority, it appears beyond a doubt that the civil and canon laws, though admitted in some cases by custom in some courts, are only subordinate and _leges sub graviori lege_; and that, thus admitted, restrained, altered, new-modelled, and amended, they are by no means with us a distinct independent species of laws, but are inferior branches of the customary or unwritten laws of England, properly called, the king's ecclesiastical, the king's military, the king's maritime, or the king's academical, laws. LET us next proceed to the _leges scriptae_, the written laws of the kingdom, which are statutes, acts, or edicts, made by the king's majesty by and with the advice and content of the lords spiritual and temporal and commons in parliament assembled[b]. The oldest of these now extant, and printed in our statute books, is the famous _magna carta_, as confirmed in parliament 9 Hen. III: though doubtless there were many acts before that time, the records of which are now lost, and the determinations of them perhaps at present currently received for the maxims of the old common law. [Footnote b: 8 Rep. 20.] THE manner of making these statutes will be better considered hereafter, when we examine the constitution of parliaments. At present we will only take notice of the different kinds of statutes; and of some general rules with regard to their construction[c].
