[IDEM libro tertio decimo ad edictum. ] §50.17.121.prQui non facit quod facere debet, uidetur facere aduersus ea, quia non facit: et qui facit quod facere non debet, non uidetur facere id quod facere iussus est.
[THE SAME, in the thirteenth book on the edict.] He who does not do what he ought to do is deemed to act contrary to those things, because he does not do it; and he who does what he ought not to do is not deemed to do that which he was ordered to do.
