- A doubtful law is not binding.
A Latin sentence; from lēx ("law") + dubia ("doubtful") + nōn ("not") + obligat ("is binding"). (Wiktionary)
Æquiprobabilists in reply say that the axiom lex dubia non obligat holds when the law is strictly doubtful, i.e. when the reasons for and against the law are equal or nearly equal.
