There is criminal, not civil courts, that were sucessfully drowned in the cum-ex robberies. They gave up on prosecuting people who stole billions from the federal budget, because they were unable to process the amount of files brought by the defense, before the statue of limitations expires.
So if even prosecuting theft of billions of Euros is subject to this tactic smaller civil cases can be too. And the court, because of their lack of technical understanding struggle to assess which files are relevant and which aren’t.
