In the 2019 parliamentary election, Sandu's PAS, together with its ally, PPDA, led by Andrei Năstase, formed the ACUM Electoral Bloc and secured 26 of the 101 seats in the Parliament of Moldova. On 8 June 2019, Maia Sandu was elected Prime Minister of Moldova in a coalition government with PSRM. On the same day, the Constitutional Court of Moldova declared unconstitutional her designation for this position as well as the appointment of the Government of the Republic of Moldova, which sparked the 2019 constitutional crisis. However, on 15 June 2019, the Constitutional Court revised and repealed its previous decisions, declaring the Sandu Cabinet to have been constitutionally created.
