Recognized with the Marie Juchacz Women's Prize [de] in 2019, she continued her legal career until her death in Berlin on 2 September 2023, at the age of 90.

She served as the chairwoman of the German Association of Women Lawyers (Deutscher Juristinnenbund [de]) from 1977 to 1981 and joined the Social Democratic Party (SPD) in 1988.

'[6] In 1988, as part of Emma magazine's PorNO campaign, a legislative proposal aiming to establish a German law against pornography, developed in collaboration with Peschel-Gutzeit, was published; however, it did not get implemented.

She held this position until the end of 1993, when the SPD lost the absolute majority and formed a coalition with the STATT Party (Voscherau III Senate [Wikidata]).

[5] She left this office in 1997 to once again assume the position of Senator for Justice in Hamburg, this time under Ortwin Runde (SPD) in a coalition with the Alliance 90/The Greens.

[3] She implemented corresponding legislative proposals, such as the 'Lex Peschel' (§ 92 BBG), which stipulated that civil servants could work part-time for family reasons.

[11] She also advocated for the 'right to vote from birth,' allowing parents to exercise this right on behalf of their children until they reached adulthood, as discussed in the Neue Juristische Wochenschrift.
