True, but while I don't know Austria's laws, I know that in any country that isn't fully corrupt (and even in many of them) anyone can take anyone to court for anything. There are different rules around loser pays (there is no good answer here - only bad compromises) and how fast the judge will dismiss fraudulent claims, but if there is anyone who can't get a day in court over a legitimize issues the country is corrupt. Austria isn't perfect (no country is), but there international reputation isn't nearly bad enough that I would expect someone to be unable to get your in court for anything they want.
