sui juris

As regards persons in private custody, e.g. persons not sui juris detained by those not entitled to their guardianship or lunatics, or persons kidnapped, habeas corpus ad subjiciendum seems not to have been the ordinary common law remedy.

No Roman patrician was ever imbued with a greater sense of the sui juris of the sacred rights with which "the city" had invested her.

In the years before the war, when the influx of patients from all parts made me independent of the favor or disfavor of my native city, I followed the rule of not treating anyone who was not sui juris, was not independent of all other persons in his essential relations of life.

While, therefore, the universal has its reality only in the individuals to which it communicates itself, and which thus embody it, the individual has its reality in itself and of its own right, so to speak: when it actually exists it is “sui juris,” and as such incommunicable, “incommunicabilis”.

It makes this nature sui juris, incommunicable, and entirely independent in the mode of its actual being: leaving untouched, of course, the essential dependence of the created “subsisting thing” or “person” on the Creator.
