Manuscript written in England containing various works on canon law, including the 'Casus decretalium' of Johannes Burgundus de Maioricis; a summary of the 'Decretales - Liber Sextus' of Pope Boniface VIII; the 'Apparatus ad Constitutiones Clementinas' possibly by Gulielmus de Monte Lauduno, as well as short extracts by various other authors.

The date of production of the manuscript is unclear. A 19th-century pencil inscription on the recto of folio i suggests that it is a work of the 14th century, as does the folio catalogue entry. The summary catalogue entry and a sale catalogue excerpt within the manuscript both attribute the work to the 15th century. Dolezalek offers either the 14th or 15th century as the date of production.

The work is in a minuscule cursive Bastarda Anglicana bookhand with between 30 to 34 lines to a page.

The text has been written by several contemporary hands. Dolezalek has identified two possible authors, 'Boolond' and 'Chicheley'. For the supposed signatures of these scribes see folios 144v, 145v and 146r. Throughout the work a scribal textual apparatus is supplied in the margins.

There are few decorative elements within the work. There is a running header in red, with 'L' for 'Liber' and a Roman numeral on each verso and recto, respectively. This runs up to 'L VII' on folio 143v. Chapters divisions and paraphs are supplied in red and large initials are stroked with red. On folio 1r is a large decorated initial in blue with penwork and outlines of ivy ornamentation in red and blue. Folios 3 to 11 also contain initials with ornamentation extending into the margins. Folio 78 recto has a large anthropomorphic initial in red. On folios 12r and 13v there are marginal sketches of human heads and animals in red.
