Despite the six-months term determined by the Treaty of Saint-Germain, the referendum was not held in Zone A until October 10, 1920. In addition to changing the date of the plebiscite, other terms of the Treaty of Saint-Germain allegedly were ignored or changed: an Austrian representative was accepted into the commission, and the plebiscite commission changed rules by not allowing the Yugoslav military to control the border between Zones A and B on 8 June 1920. Instead the Yugoslav army had to withdraw from Zone A in accord with the decision of the plebiscite commission on 18 September 1920. Changes may also have been made in electoral registers which allowed people from northern Zone B voting in Zone A, backing the Austrian side. In the following decades both sides would continue to interpret and instrumentalize the plebiscite's circumstances in their own way.
