Friday's ruling by the Constitutional Court invalidating the outcome of the May 22 election means that Norbert Hofer of the Freedom Party (FPOe) will have another shot at becoming the EU's first far-right president.
I am "disappointed, ashamed.... The fact that this sloppiness and breaking of the law took place has shaken me massively," Wolfgang Sobotka told Oe1 public radio, adding that he felt "embarrassed".
The court's ruling, triggered by an FPOe legal challenge, found that postal votes in 14 areas -- or 78,000 votes -- were opened too early or by unauthorised persons, and so could in theory have been tampered with.
Newspapers on Saturday were outraged. The Oesterreich tabloid called Austria a "banana republic -- probably the only country outside Africa and Kazakhstan that is unable to count votes properly".
"It's amazing that in a Western democracy an election has to be repeated," said voter Hermann, 36, as he waited for a bus in Vienna. "The whole thing is stupid," agreed pensioner Josef, 80.
"There will be no results before all votes, including postal votes, have been counted," he said.
Possible legal changes under discussion include allowing postal votes to be counted on the day of the election, and not the day after as now, Sobotka said.
The Kurier daily reported that Sobotka wants to have election observers from the Organization for Security and Co-operation in Europe (OSCE) present for the next round.
Traditionally the president's job has been largely ceremonial but Hofer has indicated that he will make use of hitherto untapped powers afforded under Austria's constitution.
