In the following contribution, the author analyses the Provincial Assembly appearances of the Lower Styrian deputy Ivan Dečko during his last term (1902–1907). Although the Slovenian side failed to win in the city (at the level of the Provincial and National Assembly; the closest they came to victory was in 1901), the Celje Germans followed the Slovenian national progress with increasing concern. However, the urban elite refused to yield to the Slovenian demands for a grammar school within the city territory. Meanwhile, Dečko apparently “forgot” the decision of the Slovenian politicians not to agree to any compromises in this regard, and he arbitrarily offered a part of his property behind the “city walls” in Gaberje as the location where the Slovenian grammar school could be built. His move turned out to be a perfect tool for the conservatives to attack him and indirectly also the liberals in Celje. Ultimately, this led to the definite end of the Lower Styrian policy of “Concord”.
