In response to your question about the cases in Liechtenstein and Switzerland, I want to remind you that a new phenomenon has emerged in how information was brought to the attention of the tax authorities of various countries. This phenomenon is that of the "super" tax informant who sells tax lists to countries all over the world. This was the case in Liechtenstein and Germany, where a tax list was sold for 4.8 million euros.
