14. In pari causa potior est conditio possidentis.
Cf. D. 50. 17. 128. pr.: In pari causa possessor potior haberi debet. Also D. 20. 1. 10. D. 6. 2. 9. 4.
Possession and ownership—fact and right—enjoyment and title—are presumed by the law to be coincident. Every man may therefore keep what he has got, until and unless some one else can prove that he himself has a better title to it. See § 107.
