"A Berlin school has banned its students from speaking languages other than German while on school grounds.
'The language of our school is German, the official language of the Federal Republic of Germany,' reads the 'house rules' of the Herbert-Hoover Realschule, which every pupil is required to sign. The rules go on to say that, 'Every pupil is obliged to only communicate in this language [German] within the jurisdiction of the house rules.' The rules' jurisdiction is defined as including not only the school itself and its grounds, but also school excursions."
