The legal principle, "ex injuria jus non oritur" (law cannot arise from unjust acts), differs from the competing principle of "ex factis jus oritur" (the facts determine the law). On one hand, legal recognition of Baltic incorporation on the part of other sovereign nations outside the Soviet bloc was largely withheld based on the fundamental legal principle of "ex injuria jus non oritur", since the annexation of the Baltic states was held to be illegal. On the other hand, "de facto" interruption of statehood due to foreign occupation for a period of fifty years did indeed occur, giving a place to the legal principle of "ex factis jus oritur", as well as irrevocable territory and demographic changes that make the Baltic case much more complex than mere "restitutio in integrum" (a restoration of—in this case—territorial integrity).
