In a high-stakes meeting of interior ministers, Austria was the only country that opposed Romania’s accession into Schengen.
The reasoning behind Austria’s decision is greater than the blocking of Rommania’s accession into Schengen, as it shows and brings to a head the problems with Schengen. If there was no Schengen then the current illegal immigration into France and then into the UK would have been mitigated, as currently once into the EU area, Schengen allows free travel through to France until they come to the North coast of France and the last travel of illegal entry in boats that are very unsafe for the journey across the English Channel. Also it encourages the criminal gangs to enter into these ventures.
