Rhet. Her. 1.2 quoad eius fieri poterit contains the surprising reading quoad eius. Earlier scholarship has debated the authenticity of this reading and its relationship to quod eius. A survey of the sources shows that quod eius appears in a number of inscriptions as well as in the transmitted text of nine passages within surviving Latin literature. So that phrase must be authentic; it appears to have arisen as a limiting formula in the language of the law. In two other passages, quoad eius appears in inferior manuscripts that lack authority, while the reading transmitted by authoritative textual sources is quod eius. Rhet. Her. 1.2 is the only passage in which quoad eius is the transmitted reading. This phrase is also linguistically problematic. Hence it is very likely to be corrupt. It probably arose as a conflation of quod eius with quoad, both of which are attested in similar contexts. On balance, it seems more likely that the original reading in this passage was quoad.
