Commentaries on the Laws of England: Book the First

What is said of our gentlemen in general, and the propriety of their application to the study of the laws of their country, will hold equally strong or still stronger with regard to the nobility of this realm, except only in the article of serving upon juries. But, instead of this, they have several peculiar provinces of far greater consequence and concern; being not only by birth hereditary counsellors of the crown, and judges upon their honour of the lives of their brother-peers, but also arbiters of the property of all their fellow-subjects, and that in the last resort. In this their judicial capacity they are bound to decide the nicest and most critical points of the law; to examine and correct such errors as have escaped the most experienced sages of the profession, the lord keeper and the judges of the courts at Westminster. Their sentence is final, decisive, irrevocable: no appeal, no correction, not even a review can be had: and to their determination, whatever it be, the inferior courts of justice must conform; otherwise the rule of property would no longer be uniform and steady.
