[4][5] The 2019 coalition agreement of the second government of Pedro Sánchez (Spain's 14th legislature) provided for the introduction of gender self-identification (self-ID).
In 2020, at the beginning of the legislative period, the Ministry of Equality led by Irene Montero stated that it would develop a self-ID law.
[14][15][16] This refusal led the Federación Plataforma Trans to renew its call for unblocking the legal process and a boycott of Madrid Pride if no progress could be reached.
The document allowed for individuals over 16 years old to independently file for a change in legal sex without the need for a psychiatric report, as was required previously.
[30] The Ley Trans was the first of its kind to be passed and enacted in the European Union and stands as a controversial issue in the public opinion.
Proponents of this law argue that 16 year olds in Spain already have the right to work, be sexually active, and get an abortion if needed.
Others, however, are more skeptical of the law because they believe it rushes individuals into making rash decisions about their gender, leaving them no time to reflect on such an important change in their identity.
The Vox July 2023 Electoral Program reinforces opposition to hormonal treatments and sex change surgery for minors and argues the alleged unconstitutionality of the Ley Trans.
This opposition puts the ongoing 2023 Spanish government Formation under scrutiny, since some fear a Vox prime minister would roll back laws like Ley Trans.
