[PAULUS libro uicensimo primo ad edictum. ] §8.2.1.prSi intercedat solum publicum uel uia publica, neque itineris actusue neque altius tollendi seruitutes impedit: sed immittendi protegendi prohibendi, item fluminum et stillicidiorum seruitutem impedit, quia caelum, quod supra id solum intercedit, liberum esse debet.
[PAULUS in the twenty-first book on the Edict.] If public land or a public road intervenes, it does not prevent easements of a right of way on foot or for driving, nor of raising a building higher; but it does prevent easements of inserting beams, of projecting roofs, of prohibiting [these], as well as of discharge of rainwater and drippings, because the airspace that lies above that land must be free.
§8.2.1.1Si usus fructus tuus sit, aedium proprietas mea, quae onera uicini sustinere debeant, mecum in solidum agi potest, tecum nullo modo.
If the usufruct is yours, and the ownership of the building is mine, which building must bear the burdens of a neighbor, an action can be brought against me for the whole, but in no way against you.
