But neither the city of Graz  nor the diocese nor the town's parish, who administers the cemetery, did  anything to change the illegal gravestone.

Heinrich Schnuderl, a representative of  the Graz parish said: "I asked the owners of the grave  years ago to do something against it, but they refused to do  so. Legally there is nothing we can do."

Two artists are now trying to  get the case moving again by installing artwork at the site of the grave.  They say that before they opened their installation they were threatened  that there would be charges pressed against them if they went ahead with  their plans.

But German Wolfram Kastner and Austrian  Martin Krenn went ahead, saying: "The playing down of Nazi  crime has to stop."

The pair affixed a Plexiglas  board in front of the gravestone telling the story of Tita Probst.

At the official unveiling of  the board a relative of Tita Probst called the police and pressed charges  against the two artists, saying they were guilty of the crime of grave  desecration.
The artists responded by  making an official complaint, saying the continued existence of the grave  is a clear offence against the insignia law.
They said: "The argument that  this is a private grave and therefore there is nothing to do about it is  absurd, they have no right to publicly display a swastika.  "The insignia law says that symbols  of the Nazi time mustn’t be displaced in  public."
The pair say fault lies with  either the city of Graz who own the cemetery or the Catholic church, who  run it.
