The equalities watchdog has updated its guidance on how to implement the supreme court ruling on gender after the government requested changes to the original proposals submitted last year.In a statement, the Equality and Human Rights Commission (EHRC) said that after feedback from the government, as well as consultation responses and extra legal advice, it had made changes to what is officially known as the code of practice.It follows concern from a number of MPs and groups representing transgender people that the original code, sent to ministers in September under the EHRC’s then chair, Kishwer Falkner, created a legal minefield for organisations implementing it and risked in effect excluding transgender people from much of the public realm.The code sets out how businesses and other organisations should respond in practical terms to the supreme court ruling that sex in the Equality Act refers only to biological sex.A government source said the changes did not mean the guidance was being weakened and that they would provide maximum clarity on how organisations could provide services in practice.

It is now likely the code will be approved next month by Bridget Phillipson, the minister for equalities, before it comes into force across England, Scotland and Wales.Phillipson is expected to meet MPs before its publication to try to allay concerns.Interim advice from the EHRC under Lady Falkner, which was subsequently withdrawn, said the ruling meant transgender people should not be allowed to use toilets meant for the gender they live as, and that in some cases they could not use toilets consistent with their birth sex.In January, the Guardian reported that under its new chair, Mary-Ann Stephenson, the EHRC was looking at ways to adapt the formal code to lessen its impact on businesses and to ensure it tried to balance the protection of single-sex spaces with the lives of transgender people.In a statement on Tuesday, Stephenson said ministers had “recently provided us with a narrow set of comments on the draft code of practice we submitted in September”.

She said: “Having considered this feedback alongside consultation responses and further legal analysis, we have made adjustments where they help the code provide legally accurate, practical guidance that is useful to duty bearers.“These aim to strengthen duty bearers’ understanding of the law and how it applies across a range of the scenarios they encounter day to day, so that all service users are treated with dignity and respect, in line with the Equality Act.”The Conservatives condemned the decision to update the guidance, saying it was an excuse for delay.Maya Forstater, the chief executive of the sex-based rights campaigners Sex Matters, raised concerns about “negotiations and horse-trading” between the government and the EHRC.Government sources rejected this, saying Phillipson was seeking both to get the guidance right and to take a sober, collaborative approach.

“The aim is to dial down the heat.A destructive culture war doesn’t help anyone,” one said.Officials say they have found the approach of the EHRC notably more constructive since the change of chair.In a written statement, Phillipson thanked the EHRC for its updates and said: “This government has always supported the protection of single-sex spaces based on biological sex.”She said the government was unable to make further announcements because it was within the pre-election period for the Scottish and Welsh parliamentary elections.

However, Forstater rejected this, saying: “It’s extraordinary that a year after the supreme court judgment, and seven months after the independent regulator first submitted its code of practice, the government has found another excuse for delaying the guidance,” she said.“The past year’s delay has caused serious harm to countless women.The statement that the government has ‘always supported the protection of single-sex spaces based on biological sex’ is a slap in the face to these women and girls who have faced harassment and hounding from jobs and services for saying the same thing.”Alex Parmar-Yee, the director of the Trans+ Solidarity Alliance group, said: “We’re glad that the government has heard how cruel and unworkable the EHRC’s original proposals were.A national bathroom ban under the guise of equality law is not in line with Labour’s values, and we hope any new guidance scraps that idea for good.

“For trans people and inclusive organisations, the last year has been horrific – now we have to find out whether this government has taken its responsibilities seriously and fixed this mess or not.”The equalities charity Stonewall welcomed the “constructive working” between the government and EHRC.“Following a year of complex judgments in the courts and the uncertainty this has created, it is essential that organisations can look to the code for practical, workable guidance and feel confident about their legal obligations,” said a spokesperson.
