Vat. lat. 8782, fol. 92v

Nemini quippe ius suum est detrahendum

Dig.1.6.2: Ulpianus ‘Si dominus in servos saevierit vel ad impudicitiam turpemque violationem compellat, quae sint partes praesidis, ex rescripto divi pii ad Aelium Marcianum proconsulem Baeticae manifestabitur. Cuius rescripti verba haec sunt: 'Dominorum quidem potestatem in suos servos illibatam esse oportet nec cuiquam hominum ius suum detrahi.  Sed dominorum interest ne auxilium contra saevitiam vel famem vel intolerabilem iniuriam denegetur his qui iuste deprecantur.’

If a master savages his slave or forces him into committing some indecency and foul malpractice, a rescript of the Emperor Pius to the Proconsul Aelius Marcianus of Andalucia, Spain explains his duties:  "The powers of masters over their slaves certainly should remain intact; no man should be deprived of his right (Ius).  But it is in the interest of the owners that those who make a just complaint should not be denied help against brutality or starvation or intolerable damage (unlawfulness)."
