The Supreme Court ruling on the meaning of Sex gave us clarity.

Now the Data Bill will torpedo that

@telegraph reports as MPs vote down amendment that would have allowed people to prove their sex using accurate data

telegraph.co.uk/news/2025/05/0… The system will allow males to apply for jobs as "female" carers using the government endorsed apps.

@hen10freeman says she needs female only care to maintain her comfort, dignity and safety. Image

Update from Maya!

The fallout from the Supreme Court judgment is continuing thick and fast this week, and Sex Matters has been busy! Update from Maya Some organisations recognise that they need to change their practices, and others resist. The EHRC put out a very clear interim update on the practical implications of the judgment.

Dear Simon Blake,

Stonewall is acting irresponsibly and contravening its charitable objects by claiming wrongly that the #SupremeCourt FWS judgment is not the law.

We will refer @stonewalluk to the Charity Commission unless it retracts this statement. Image

Fantastic coverage of @forwomenscot’s win at the Supreme Court.

Years of stellar reporting by many media outlets in Scotland and wider UK meant well-informed correspondents able to produce a wealth of comprehensive and insightful news articles.

Here are some highlights…. /1 @SanMan1978 reported in her new role for @TheTimes on what the ruling means for women’s sports and single-sex services.

Following the Supreme Court judgment the Equality Act is clear

What should the government and regulators do now?

sex-matters.org/posts/updates/… (1) NHS bodies should review policies & ensure they recognise & record immutable biological sex. This includes in relation to single-sex hospital accommodation ( “Annex B” ), single-sex facilities for staff at work, the patient records & staff records, and the provision of same-sex care.

Last weekend I had my first in-person board meeting with the new full board of Sex Matters.
Working for a virtual organisation that launched during lockdown, I still find it a (pleasant!) shock to be with so many of our human beings in one place. Image Here I am (after the meeting) with our board members (left to right): Naomi Cunningham, Emma Hilton, Anya Palmer, me, Michael Biggs, Julia Casimo, Claire Weir, Rebecca Bull, Charlotte Cadden, Tim Allan and Kate Owen.

The government is seeking to remove safeguards from the #DataBill, saying that they breach human rights.

Today we are publishing a paper which shows that, far from this being the case, the three safeguards are necessary to support everyone’s human rights 🧵 Image Lord Arbuthnot of Edrom – the parliamentary hero of the Post Office scandal – has provided a foreword to the report.

Update from Maya!

This week we learnt that the National Police Chiefs’ Council is proposing to adopt new guidance encouraging police forces to allow male officers with a gender-recognition certificate (GRC) to strip-search women and girls. Image The Kafkaesque guidance says that if a detainee objects, the officer may be swapped out, but consideration should also be given to the manner in which the detainee objects “and any prejudicial language should be dealt with positively”.

The case being heard today (and tomorrow) by @UKSupremeCourt will test the legal uncertainty about how GRCs interact with the Equality Act.

There is no ambiguity, however, about the lawfulness of women’s sport 🧵 Whatever the outcome of the FWS case it is clear that female-only competition is lawful.

🔹The #EqualityAct, section 195, says that it is permissible to discriminate by sex in a sport in which the physical strength, stamina or physique of average persons of one sex would put them at a disadvantage compared to average persons of the other sex.

🔹It also makes specific provision to allow gender-reassignment discrimination wherever it is necessary to secure fair competition or the safety of competitors.

Any sport that runs separate competitive categories for men and women, or boys and girls, is relying on s.195 ⬇️Image

Last weekend I attended the Bigger Picture conference held by @genspect in Lisbon. Helen Joyce speaking at the Genspect conference It was Genspect’s third conference in under 18 months – a remarkable achievement for a small, newish organisation and another step towards fighting back against the “gender affirming” model of healthcare for trans-identifying people…

NEW BLOG POST: on our schools model policy

Why "watch and wait" doesn't work for schools.

sex-matters.org/posts/updates/… The draft DfE guidance says “Allow for watchful waiting: Wait for a period of time before considering a request, to ensure it is a sustained and properly thought through decision. This period of ‘watchful waiting’ may help to ensure unnecessary action is not undertaken.”

Update from Maya!

Last year, while I was on a summer holiday, I was emailed by the Metropolitan Police and told I was under investigation for the crime of “Malicious Communications”. Now I’ve been told that the case has been referred to the Crown Prosecution Service… Maya Forstater crossing her index fingers to symbolise XX chromosomes. My crime was to tweet about a male doctor who was presented to patients as a woman and allowed to examine them without their informed consent.

Today we ran a briefing on the facts and science behind the women’s boxing row at the #Olympics

Thanks to @DerryBanShee, @FondOfBeetles, @mara_yamauchi & @sharrond62 for speaking.

The full video is now available on our YouTube ⬇️
@DerryBanShee @FondOfBeetles @mara_yamauchi @sharrond62 Male advantage over females in sport is huge. You can see it in the Mixed 4 x 400 relay at the 2019 athletics World Championships – watch the best women in the world be overtaken easily. That’s male advantage.

On Thursday and Friday this week, the Olympics is expected to feature male boxers in the ring with women. And that’s after Zambia fielding a women’s football team suspected to include male players.

What’s going on at the Olympics? 🧵
The footballers were previously ruled out of the Women’s Africa Cup of Nations, supposedly because of high testosterone. In this context, “female with high testosterone” usually means male with female passport.
