The proposed constitution, which had faced "intense criticism that it was too long, too left-leaning and too radical",[4] was rejected by a margin of 62% to 38% in the 2022 Chilean national plebiscite.

[1] The same two-thirds quorum will be applied to make any decision, which implies that the points that do not generate said consensus will be left out of the draft text of the new Political Constitution.

In the same way, the current Constitution establishes that the text presented by the Convention must respect the democratic regime, judicial decisions and international treaties.

[14] In the event that there are claims for alleged violations of the procedural rules applicable to the Convention, these will be known and resolved by five members of the Supreme Court, chosen by a draw.

[16] However, several parliamentarians demonstrated against occupying the headquarters of the former Congress in Santiago, since according to them other legislative tasks and meetings with civil society are carried out in that building and would not present the necessary infrastructure.

[19] On 11 January 2021, President Sebastián Piñera announced the Pereira Palace as the working headquarters of the Constitutional Convention.

In that ceremony, president Gabriel Boric signed the decree convoking the national plebiscite for September 4, 2022, where the Constitution was to be subject to approval or rejection by the Chilean citizens.

[24] The proposed Constitution would have retained free-market economics while introducing social rights,[25] and would have reformed the Senate of Chile into an indirectly-elected chamber representing regional councils.

[28][29] After the referendum the former members of the Constitutional Convention Constanza Schönhaut, César Valenzuela, and Ricardo Montero entered to work in the Boric government.
