The cross-party committee of MPs has written to the UK’s equal regulator in seeking guidance on how their organizations interpret the landmark Supreme Court ruling, which does not ignore the needs of transgender people.

The letter from the Commission on Civilians and Human Rights, Kishwer Falkner, also urged her to extend the two-week schedule so that people can submit opinions on how the organizational code of EHRC organizations should work, saying that this should be at least six weeks.

It was the concern of trans activists and many members of Congress, and so far Mrs. Faulkner and his organization have taken an overly literal approach to the Supreme Court decision last month, which ruled that the “woman” in the Equality Act is just a biological woman.

Falkner immediately said the ruling meant that only biological women could use single-sex locker rooms and women's restrooms, or participate in women's sports events and teams, or place them in women's wards in hospitals.

The EHRC’s interim guidance lists this more formally, saying that in some cases, trans men born in women should not use male toilets, while adding that trans people “should not place trans people where there is no facility to use”.

Although ministers welcomed what they called the “clearity” of rulings and guidance, many MPs are concerned about the impact on trans people, for example, whether people who have lived as women for decades must suddenly start using men’s toilets.

Labor MP Sarah Owen, chaired by the Chairman's Women and Equality Committee, said many trans people were "anxious and unsure where the ruling stayed".

The letter sent on behalf of the entire committee, asking Forkner to provide information on several key points, including: “What steps will the EHRC take to ensure that the Code of Practice supports the rights of all persons (as noted in the Supreme Court judgment).

It also asked: “Does the code of practice articulate the rights of trans people, such as police surrounding rulings?”

After the ruling, the British Transport Police said it had updated its policy to conduct a search for detention “based on biological birth sex of the detainee”, meaning that trans women will be ruling by male officials in the future.

On the two-week consultation schedule, the committee asked: “What is the reason for the decision to be during the two-week consultation period, for example, how will the consultation work in practice, for example, will the EHRC proactively seek advice from any particular group or stakeholder?

“As a committee, we believe that at least six weeks is more appropriate to allow donations from all stakeholders, including individuals, charities and groups of people with disabilities, businesses, health providers and local authorities.”

The letter also asked Falkner to suggest the organizations that make queries before new code is available and when to finalize.

It also noted that the ruling meant that “there may be legal implications beyond the scope of the issues considered by the Supreme Court”, asking whether the EHRC would accept submissions regarding these submissions.

An EHRC spokesperson said: “We will carefully consider the letters from the Women and Equality Commission (WEC) and provide a comprehensive response to their views.

“In view of statements obtained from WEC and others, we are actively reviewing the approach to consulting methods for the code of practice updated following the Supreme Court’s judgment.

“We will publicly announce that consultations will be open and closed and how we plan to interact with affected stakeholders.”
