Discusses the difference between the duty of advocacy and the defense of one's own property, stating that assisting another's claim in ignorance does not forfeit one's own ownership upon subsequent discovery.
[ULPIANUS libro sexto opinionum.]
[ULPIANUS in the sixth book of Opinions.]
Inter officium aduocationis et rei suae defensionem multum interest: nec propterea quis, si postea cognouerit rem ad se pertinere, quod1 alii eam uindicanti tunc ignorans suam esse2 adsistebat,3 dominium suum amisit.
There is a great difference between the duty of advocacy and the defense of one’s own property: nor, on that account, does anyone lose his ownership, if he afterwards learns that the property belongs to him, because he was assisting another who was claiming it, being at that time ignorant that it was his own.
- 6.1.54.prnec propterea ... quod
The adverb propterea ("on that account") is explained by the subsequent quod clause ("because..."). The structure nec propterea... quod expresses the denial of causal connection: "nor, for the reason that..., does he on that account lose...".
- 6.1.54.prignorans suam esse
ignorans ("being ignorant") is a present participle modifying the subject of the clause. suam esse is an accusative with infinitive construction acting as the object of ignorans, where the accusative subject rem (referring to the property) is omitted, meaning "ignorant that [the thing] was his own".
- 6.1.54.pralii eam uindicanti ... adsistebat
The verb adsistebat ("was assisting") governs the dative, here represented by alii ("another"). The present participle uindicanti agrees with and modifies alii, meaning "to another who was claiming it".
