In today's post, Han Edgoose develops a concept of hermeneutical sabotage by engaging with the predicaments of transpeople in the UK
As Nick Clanchy has said in a previous post on this blog, it is a scary time to be a trans person living in the UK right now. An April 2025 UK Supreme Court ruling, which defined ‘sex’ for the purposes of the Equality Act (the UK’s major piece of equalities legislation) as ‘biological sex’, has been interpreted by the Equality and Human Rights Commission (EHRC), the public body in charge of enforcing equalities legislation in the UK, as a trans bathroom ban.
The EHRC’s interim guidance on the Supreme Court ruling not only bans trans people from using toilets and other single-sex spaces and services such as changing rooms and hospital wards that align with their identity, it also allows for them to be excluded from single-sex spaces that align with their sex assigned at birth. By severely restricting trans people’s ability to access toilets this ruling limits trans people’s ability to exist in public spaces and workplaces.
It also curtails trans people’s ability to ensure their own health and wellbeing by restricting their access to domestic violence shelters and healthcare, and their ability to participate in sports. Shockingly, the Supreme Court judges claimed that this ruling ‘does not cause disadvantage to trans people’.
The injustice caused by the Supreme Court ruling is not primarily epistemic. However, epistemic injustice is often a contributory factor to other injustices, and it is in this case. There are multiple ways in which the Supreme Court ruling could be understood to be committing epistemic injustice, but I’m just going to focus on one aspect of the ruling: its re-definition of the term ‘lesbian’, which, I argue, amounts to hermeneutical sabotage.
Hermeneutical sabotage
In a paper published in the Australasian Journal of Philosophy last year, I argued that a form of epistemic injustice I name ‘hermeneutical sabotage’ is used as a tactic by harmful political movements to help them achieve their exclusionary and oppressive goals. Hermeneutical sabotage occurs (roughly) when the widely available conceptual resources for understanding the identity or experience of a marginalised group are actively worsened.
This can be done in multiple ways, including by introducing new, prejudiced hermeneutical resources and distorting resistant hermeneutical resources developed by marginalised groups. Another way in which hermeneutical sabotage can occur is when particularly powerful people change the meaning of well-established terms, distorting the available hermeneutical resources. This is the type of hermeneutical sabotage that the Supreme Court Committed in their judgement on the term ‘lesbian’.
Hermeneutical sabotage and the definition of 'lesbian'
The Supreme Court ruling embraces the hermeneutical sabotage of the term ‘lesbian’ by accepting a definition of ‘lesbian’ that excludes all lesbian trans women, as well as lesbian cis women who are attracted to all women including trans women.
According to the Supreme Court ruling, a lesbian is defined as a ‘female who is sexually attracted towards… other females’, (where ‘female’ is understood to refer to ‘biological sex’). This trans exclusionary view of lesbianism was embraced despite the fact that the vast majority of cisgender lesbians in the UK are supportive of trans people, and inhibits the ability of trans lesbians, as well as trans inclusive cis lesbians, to communicate an important aspect of their identity.
This is a particularly powerful case of hermeneutical sabotage as the ruling encodes the sabotaged meaning of the term into the law. The Equality Act allows those who share a protected characteristic to organise groups and clubs that only include people who share that characteristic and exclude those who don’t.
Excluding people on the basis of one of the protected characteristics outlined in the Equality Act is otherwise illegal. By defining lesbian in a trans exclusionary way membership clubs that include people who share the protected characteristic of ‘lesbian’ can now only include or exclude people on the basis of the sabotaged definition provided by the Supreme Court. This means that it appears to no longer be legal for a lesbian organisation in the UK to include trans lesbians or cis lesbians who are attracted to trans women.
The hermeneutical sabotage of the term ‘lesbian’ is an epistemic injustice which inhibits the ability of trans and trans inclusive lesbians to use the word ‘lesbian’ to communicate their experiences effectively. The Supreme Court ruling not only intensifies this epistemic injustice by legally encoding the sabotaged meaning of the term ‘lesbian’, it also enacts further injustices as a consequence of this epistemic injustice that limit trans and trans inclusive lesbians’ ability to meet in organised groups and clubs, showing the clear connection between epistemic injustice and further non-epistemic injustices.
