Leges Brebonices, denote the general maxims or rules of law observed by the brehons, and having the force of laws throughout all the provinces of Ireland. Several fragments of the leges brebonice are still extant in public and private libraries. The most complete collection is that belonging to the duke of Chandos; containing 224 sheets close written, full of abbreviated words, and not very legible. By the statute of Kilkenny, made under Edward III., it is enacted that no English subject shall submit to a trial by the brebon law, on the penalty of high treason. Notwithstanding which, many were still under a necessity of being concluded by the Irish laws and customs, till the whole kingdom was settled on an English bottom by King James I.
