I know only a small amount of Latin.
Uti possidetis is a term used in international law to indicate that the parties to a particular treaty are to retain possession of that which they forcibly seized during a war.
In other words you and your enemy stop where you are at the moment. The treaty would have "awarded" the Federation the territory they actual held at the time and awarded the Cardassians the territory they actual held at the time. It wouldn't make any difference what was claimed, only what was possessed.
