When a Catholic newspaper of Münster, which had published extracts from "Der Judenspiegel," was sued for libel, and Prof. Jacob Ecker was chosen by the court as an expert, Briman aided him in writing his opinion ("Gutachten"), "Der Judenspiegel und die Wahrheit"; but in order to disguise this fact, some criticisms of Briman's "Judenspiegel" were inserted. Afterward Ecker published "Die Hundert Gesetze des Judenkatechismus," a literal reprint of the "Judenspiegel." In his ignorance of Hebrew and of Talmudic writings, Ecker even copied the passages which he had declared in his opinion to be misinterpreted. In March, 1885, Briman was arrested on charges of fraud not connected with his anti-Semitic writings. He was condemned to prison; and when his term was finished he was expelled from Austria. He then took up medical studies in Paris.
