The canon discusses the emancipation of children from the patria potestas, and the dangers that come with it: since the father is no longer legally responsible for the misdoings of his sons, the odium can fall on the clerics that presided over the emancipation. What interests us is that not only bishops, but also other clerics (presumably presbyters in the first place) were entitled to perform this legal action.
The canon was repeated in Registri Ecclesiae Carthaginensis Excerpta as Canon 34.
