Women's rights and abortion A new Ministry for Women and Gender Inequality was formed, replacing the National Women's Service in June 2016 which aimed to formulate policies against abuse of women and gender inequality. Claudia Pascual was appointed as the first ever Minister for Women and Gender Inequality. The Chilean Congress approved Bachelet's abortion legalization bill in some circumstances in July 2017, but was subjected to challenge in the Constitutional Court. Later, Chile's total abortion ban implemented under the Pinochet regime in 1989 was lifted in August 2017 after the Constitutional Court voted 6–4 to allow the procedure under some circumstances: in cases of pregnancy as a result of rape (up to 12 weeks), if the fetus endangers the mother's life, or if the fetus is not viable.

As a result, the 2017 election saw the end of the dominance of Bachelet's New Majority and conservative coalitions and increased number of new political parties represented in Congress.
