A trio of older Roman statutes regularly cited together by Cicero (e.g. Verr. 2.1.109) as classic examples of civil legislation: the lex Atinia (perhaps the third-century law on usucapio of stolen things), the lex Furia (probably the lex Furia testamentaria limiting bequests), and the lex Fusia (likely the lex Fufia Caninia or a related procedural statute). The grouping illustrates the principle that all transactions completed before a new statute remain valid under the old.
