[ULPIANUS libro quinquagensimo septimo ad edictum. ] §2.4.12.prSi libertus in ius uocauerit contra praetoris edictum filium patroni sui, quem ipse patronus in potestate habet: probandum est absente patre subueniendum esse filio qui in potestate est et ei poenalem in factum actionem, id est quinquaginta aureorum, aduersus libertum competere.
[ULPIANUS, in the fifty-seventh book on the Edict.] If a freedman, contrary to the praetor's edict, summons to court the son of his patron, whom the patron himself holds under his power: it must be approved that, in the absence of the father, relief should be granted to the son who is under power, and that a penal action on the facts, that is, of fifty aurei, lies for him against the freedman.
