LT practice example #21: Interpreting of witness hearings at court
... court hearings. As several of the witnesses are Italian-speaking and do not know German, which is the language of the Court, an interpreter is present at the hearings to translate the witnesses' statements into German for the Court. The same interpreter also translates the Court's questions from German into Italian.
