“Trans Rights are Human Rights,” Emma Watson’s T-shirt reads in a new Instagram post. The Harry Potter star took to social media to throw her support for the debate on the UK’s Gender Recognition Act. Watson made sure that those involved in the fight saw her photo by tagging some of the major advocates and advocacy groups in her post.

The post comes an hours before the deadline on public comment on updating the GRA—a law that initially went into place in 2004. The update would include things like allowing transgender people to self-identify their gender.

Public consultation for the GRA closes Oct. 19.
