[Year Books, 20-45 Edward III.] Liber Assisarum (manuscript in Law French, ca. 1450).
The origin of our case reports lies in the late 13th century, with what are now called the “Year Books.” The Liber Assisarum, shown here, is a collection of Year Book cases in the court of King’s Bench in 1347-1372.
The Year Books are quite different from modern case reports. They say little or nothing about the facts, or who won. What interested the anonymous reporters was the debate between advocates and judges, a sort of tentative oral pleading that has been compared to lightning chess. The Year Books seem to have had some connection (still unclear) with legal education at the Inns of Court, but they were also used by bench & bar.
As more or less verbatim records of legal debates between named individuals, the Year Books are virtually the only historical sources that capture voices from the Middle Ages.
Maitland on the Year Books
“Today men are reporting at Edinburgh and Dublin, at Boston and San Francisco, at Quebec and Sydney and Cape Town, at Calcutta and Madras. Their pedigree is unbroken and indisputable. It goes back to some nameless lawyers at Westminster to whom a happy thought had come. What they desired was not a copy of the chilly record, cut and dried, with its concrete particulars concealing the point of law: the record overladen with the uninteresting names of litigants and oblivious of the interesting names of sages, of justices and serjeants. What they desired was the debate with the life-blood in it: the twists and turns of advocacy, the quip courteous and the countercheck quarrelsome.” – Sir Frederick Maitland, 17 Selden Soc. xv.
