[IAUOLENUS libro decimo ex Cassio. ] §39.3.18.prSi in publico opus factum est, quo aqua pluuia noceret, agi non potest: interueniente loco publico agi poterit.
[IAUOLENUS in the tenth book on Cassius.] If work is done on public land, by which rainwater causes damage, no action can be brought; if public land intervenes, an action can be brought.
causa eius rei haec est, quod ea actione non tenetur nisi dominus solus.
The reason for this is that only the owner is liable under that action.
§39.3.18.1Sine permissu principis aqua per uiam publicam duci non potest.
Without the permission of the emperor, water cannot be drawn through a public road.
