Two major international legal issues that arose during the Israel-Syria negotiations were the issue of borders and the status of offers made during the negotiations. As regards borders, Syriarefuses to accept the validity of the former international boundary claiming it was imposed by colonial powers. The rule of uti possidetis, that new States inherit colonial era borders, is now, however, a rule of customary international law. A strong argument can be made that it should be the basis of the negotiations with Israel. However, there is no legal impediment to Syria trying to change it by agreement with Israel. As to the status of offers made during negotiations. It can be argued, that although not legally binding, as a matter of good faith, offers made during negotiations should not be withdrawn so long as they are being negotiated.
