Tanson studied at
Pantheon-Sorbonne University in Paris and completed her studies with a master's degree in law and a diploma from
Sciences Po Paris. On 7 June 2015, she was appointed to the
Council of State as a replacement for Agnès Rausch. However, she resigned from that position in order to replace her party colleague
Claude Adam in the
Chamber of Deputies. She was re-elected as a deputy in the
October 2018 general election. Nonetheless, she resigned from her seat to take office as the Minister of Housing and the Minister of Culture within the
Second Bettel–Schneider Ministry on 5 December 2018. On 6 September 2019, Tanson became the interim Minister of Justice as a replacement for
Félix Braz, who suffered from severe illness. She was appointed as the titular Minister of Justice on 25 September 2019. She was the Greens' national lead candidate in the
2023 general election, in which the party suffered a considerable loss in vote share, going from nine seats in the
Chamber of Deputies to four. With the formation of the
CSV-
DP coalition government led by
Luc Frieden, the Greens went into the opposition, with Tanson returning to the Chamber as a deputy. ==References==
