William Blackstone, Commentaries 1:257

III. Another capacity, in which the king is considered in domestic affairs, is as the fountain of justice and general conservator of the peace of the kingdom. By the fountain of justice the law does not mean the author or original, but only the distributor. Justice is not derived from the king, as from his free gift; but he is the steward of the public, to dispense it to whom it is due. He is not the spring, but the reservoir; from whence right and equity are conducted, by a thousand chanels, to every individual. The original power of judicature, by the fundamental principles of society, is lodged in the society at large: but as it would be impracticable to render complete justice to every individual, by the people in their collective capacity, therefore every nation has committed that power to certain select magistrates, who with more ease and expedition can hear and determine complaints; and in England this authority has immemorially been exercised by the king or his substitutes. He therefore has alone the right of erecting courts of judicature: for, though the constitution of the kingdom hath entrusted him with the whole executive power of the laws, it is impossible, as well as improper, that he should personally carry into execution this great and extensive trust: it is consequently necessary, that courts should be erected, to assist him in executing this power; and equally necessary, that, if erected, they should be erected by his authority. And hence it is, that all jurisdictions of courts are either mediately or immediately derived from the crown, their proceedings run generally in the king's name, they pass under his seal, and are executed by his officers.
