As a political officer, Hüber was responsible for giving the soldiers political instruction and propaganda. He worked for the Berlin regiment 33 (Treptow). His unit was responsible for the fatal shooting on February 6, 1989 of Chris Gueffroy, the last person to be shot on the inner German border.
Hüber has tried to ban the mention of his name in connection with his work as political officer and has sued a German historian.
His case and the question of how to deal with moral responsibility have been widely discussed in German newspapers. The interim injunction was later cancelled, as his name was considered to be of "historical interest".
