On 17 March, the government registered its proposition of what would become the Ley trans: the . It was supported by the Federación Plataforma Trans. On 18 March 2021, the law was refused treatment by a vote with No votes coming from right-wing parties Vox and Partido Popular, and abstention from the Socialist Workers' Party. This led the Federación Plataforma Trans to renew its call for unblocking the legal process, and for a boycott of Madrid Pride if no progress could be reached. This led to the exclusion of Carmen Calvo from the parliamentary negotiations. On 29 June 2021, the Ministry of Equality presented to the Council of Ministers its draft for the Ley trans. The document provided for gender self-ID for anyone over 16 years. On 27 June 2022, the bill returned to the Council of Ministers, which approved it, so it became a legal project. This was the final, more version of gender self-ID, which was more liberal compared to the original draft: self-ID was to be possible from 14 years with parental or guardian consent, and freely from 16 years. A gender change from 12 to 14 years of age was to be possible with judicial authorisation only. First reading in the Congress The draft was approved at first reading on 21 December 2022, with 188 votes in favour, 150 opposed, and 7 abstentions. The abstentions included Carmen Calvo, and three other Socialist deputies. Approval in the Senate The Spanish upper house, the Senate, debated the law from 20 January 2023. The Socialist Workers' Union reaffirmed its intention to request modifications to the law. The law passed the Senate, however, on 9 February 2023 with 144 Yes votes, 108 No votes, and 2 abstentions. Second and final reading in the Congress The Ley trans passed its final voting phase in the Congress on 16 February 2023. It was made law with 191 votes in favour, 60 against, and 91 abstentions.
