“Frank law … may be understood from Bracton’s description of the consequences of losing it, among which the principal one was, that the parties incurred perpetual infamy, so that they were never afterwards to be admitted to oath, because they were not deemed to be othesworth, (that is, not worthy of making oath,) nor allowed to give testimony.” 1 Alexander M. Burrill, A Law Dictionary and Glossary 657–58 (2d ed. 1867).
