This paper provides an edition, translation and discussion of a bipartite Old-Irish text on court procedure. The first section, in straightforward Old-Irish prose, lists the sixteen persons (or categories of persons) who may be present at a court session and indicates where each of them should sit in relation to the judges. This section provides some information on the part played by both king and judges in reaching and promulgating a verdict. It also touches on the role of sureties, witnesses and custodians of tradition (senchaid) in court. The second section is in the obscure rosc style and contains early spellings which indicate that it was composed before the first section. It seems to be a riddle about court procedure to which the answer may be ‘judgement’ or ‘verdict’.
