Dr. Konstantin von Notz joined the German Green party Bündnis 90/DIE GRÜNEN in 1995 in Heidelberg. After moving to the state of Schleswig-Holstein in northern Germany, he became a member of the party's Herzogtum Lauenburg district chapter in 2004. He was elected to the Mölln City Council in the same year. Von Notz served as head of the Green party's representatives on the council until 2009. He has been vice mayor of Mölln since June 2013.
During elections to the German national parliament held between 2002 and 2013, he has run for a seat in election district 10 (Herzogtum Lauenburg/Stormarn South).
Konstantin von Notz has served in the German Parliament since 2009. The focus of his parliamentary work is social affairs, domestic and legal issues. During the parliament’s 17th legislative period, he served as the spokesman on domestic and digital-related issues for the parliamentary group of Bündnis 90/Die Grünen, the spokesman of the Greens’ parliamentary group on the Enquete Commission “Internet and Digital Society,” a full member of the Parliament's Committee on Internal Affairs, and a deputy member of the Legal Affairs Committee and the Subcommittee on New Media. He also represented the Greens’ parliamentary group on the Information and Communications Technologies Commission of the Council of Elders.
Since then, one of his special focal points has been issues related to the digital world. In these activities, he works to defend and strengthen the fundamental values of freedom, justice and citizens’ rights particularly in this digital world.
In December 2013, the Greens’ parliamentary group elected him to serve as its deputy chairman. As coordinator of the Working Group III, he is responsible for such issues as domestic, legal affairs and judicial policies; data and consumer protection; equal opportunities and anti-discrimination matters; oversight of intelligence agencies; migration, refugee and asylum concerns; digital matters; sports policy; and church-related issues.
In August 2015, the Association of Friends of the Protestant Academy of Baden honored Konstantin von Notz for his work on behalf of digital citizens’ rights with the Bad Herrenalb Academy Award. The association presented the award on the occasion of the 2014 address given at the Albert Ludwig University in Freiburg on the topic “Will machines change our conception of humankind? The New Approach to Information and Data.”
