The UK Supreme Court ruled on Wednesday (April 4) that the definition of "woman" in the Equality Act should be based on biological sex. In response, JK Rowling, author of the Harry Potter series, expressed her support on the social media platform X on Thursday (16th), calling the ruling "a victory for all women."

The lawsuit began in 2018, with the Scottish government arguing that transgender people with a Gender Recognition Certificate (GRC) should enjoy the same gender protections as biological females, while the Women's Group Scotland (FWS) argued that these protections should only apply to people who were born female. After years of litigation, the UK Supreme Court finally made it clear in its judgment that "women" in the Equality Act should be interpreted as "biological females" rather than determined by "gender identity."
It is understood that JK Rowling is a long-term supporter of the case. After the verdict was announced, she said on the X platform, "The reason why this legal battle has lasted to the Supreme Court is because of the perseverance of three Scottish women and all the forces supporting them. This is a great guarantee for women and girls across the UK." She also admitted that she had funded the Scottish Women's Organization, praised the initiators of the lawsuit as "extraordinary and determined", and uploaded a photo of herself celebrating on a yacht.
In recent years, JK Rowling has repeatedly expressed her support for the position of "biological sex". She has even likened gender-affirming surgery to "frontal lobotomy", questioned the legitimacy of children being "born in the wrong body", and criticized the transgender movement for "invading women's space".
It is worth mentioning that the main cast of the "Harry Potter" film series have expressed support for the transgender community due to their different positions. In addition, "Harry" himself, Daniel Radcliffe, also publicly stated in June 2020 that "transgender women are women."
