Should the UK have a simple, clear legal definition of sex, male and female?

To follow on from https://www.mumsnet.com/talk/womensrights/5533120-5533120-should-the-gender-recognition-act-be-repealed?page=6&reply=152596360 where 96% of voters said the Gender Recognition Act should be repealed

However, repealing the GRA alone could leave a legal gap. The GRA is not the only source of confusion. Some of the problem comes from older case law too.
There is already case law with the phrase "woman for all practical purposes" in it. This comes from a 2004 House of Lords case involving a transsexual police applicant. The applicant was male, had undergone surgery, and wanted to be treated as female for the purposes of police work. The issue was whether that male could be excluded from the job because police officers sometimes had to carry out same-sex searches. Before the GRA, the court decided that a post-operative transsexual person could be treated as their acquired gender for some practical purposes, including same-sex searches.

That is exactly the kind of ambiguity that needs fixing. Parliament should not simply repeal the GRA and leave older “practical purposes” arguments sitting there as the fallback position.

Whether the GRA is repealed, amended or left in place, we need legislation that clearly and unequivocally states the legal definition of sex, male and female.

The legal definition should say something like:

  • for the purposes of any Act, statutory instrument, public function, policy, data collection, sex-based rule, sex-based exception, sex-based service or sex-based protection, sex means biological sex in human beings, being male or female
  • male means a person whose body developed along the male pathway, organised around the production of small motile gametes, sperm
  • female means a person whose body developed along the female pathway, organised around the production of large immobile gametes, ova
  • man and boy mean male
  • woman and girl mean female
  • sex is observed and recorded at birth, not assigned; a birth record may be corrected where there has been a genuine recording error, but sex is not created by paperwork
  • actual fertility is not required; a person does not stop being male or female because of age, infertility, miscarriage, menopause, hysterectomy, vasectomy, injury, difference or disorder of sex development, medical treatment or surgery
  • people with DSDs are still male or female; DSDs are variations in the development of male or female bodies, not a third sex, and people with DSDs should always be treated with dignity, privacy and respect
  • sex is not determined by chromosomes alone, hormone levels, height, strength, appearance, clothing, hairstyle, voice, breast size, genital appearance, personality, social role, stereotypes, brain claims, feelings, belief or identity
  • sex is not changed by a Gender Recognition Certificate, passport, driving licence, NHS record, deed poll, self-identification, social transition, hormones, puberty blockers, cross-sex hormones, surgery, certificate, document, administrative record, or any other document or procedure
  • non-human examples, such as clownfish or plants, do not alter the legal definition of sex in human beings
  • gender reassignment remains a separate protected characteristic
  • trans people remain protected from discrimination, harassment and victimisation under the Equality Act; this is about defining sex clearly, not removing ordinary legal protections from trans people

This would not stop anyone living as they wish. It would not remove ordinary protections against discrimination, which should always remain. It would simply stop the state and public bodies from treating sex as a paperwork exercise.
Sex is real, binary and immutable. Most of the time, sex does not matter. But in the contexts where it does matter, it matters profoundly: safeguarding, privacy, dignity, data, sport, prisons, healthcare and single-sex services.

A proper legal definition would cut through years of ideological confusion and make the law clear again.

For example:

  • man and boy mean male
  • woman and girl mean female
They don't. Male means male. Female means female.

Man means adult, human male.
Woman means adult, human female.

Male and female are words that are used across species.
Man and woman refer exclusively to the male and female of the human species.

You don't get to define words and then say this is the true definition.

For example, if we go with your definition how does the etymology of other words, such as mankind, work?

As an aside, we are a species, scientifically speaking, and so it seems odd to want to use non-scientific language while arguing a point that's supposedly supported by scientific evidence. It's this kind of cognitive dissonance, along with the use of hallucinatory AI to produce meme-like propaganda, that's an indication of disturbing intent.

Incidentally, I worked with the probation service on a study of sexual violence. Surveying 100s of predators revealed one of the biggest determining factors was the length of the woman's hair - much easier to control someone with a handful of their hair. This would be an important factor to consider around 'keeping your daughter safe'.

Oh stop using your poor daughter as an excuse for your obsessive and hateful behaviour. You're a man who seems to split his time between a forum for mums and stalking total strangers on reddit then getting wound up because you can't control what they think or say. Take a look at yourself.

Thanks man, feeling the love. Always appreciate a different perspective.

Well, no. That is what dictionaries are for; so we can all work to an agreed definition, otherwise communication is impossible.

Do you have different definitions? If so, we'd love to hear them.

There are people who genuinely believe that the Royal Family are actually lizards. Legislating that the definition of "Lizard" does not include members of the Royal Family will not change their minds - because they are delusional.

Enforcement of existing laws would help to educate as well as to deter. Neither are 100% guaranteed to ensure that everyone will obey the law and respect the rights of others, for various reasons. Including some people who will continue to fabricate "loopholes" to justify persistent anti-social and criminal behaviour despite tight definitions.

"Why do people break traffic rules and laws?

"the evidence across many jurisdictions reveals that reliance on punishments or incentives alone does not ensure sustained compliance with traffic laws.

Measures implemented by governments, such as surveillance, penalties, incentives and infrastructure improvements, are undoubtedly essential. However, they are not the ultimate solutions since ramping up penalties has its limitations in modifying driver behaviour. There are broader societal factors that produce sustainable changes in behaviour and greater compliance with traffic laws.

Consider the simple act of stopping at a red light. It's a safety measure and also about respecting the rights of others, as well as about obeying the law. Ideally, every driver would ponder the costs and benefits before acting, thinking, "If I run this red light, I might gain a minute but risk causing an accident and disorder, disrespect to others or incurring a fine".

However, things don't always work like this. In societies where education is less accessible or misinformation is widespread, with limited access to information, drivers may make hasty, ill-considered decisions like running a red light when no police are in sight, disregarding the consequences.

On the other hand, in communities that promote education and where critical thinking is nurtured by access to free media and information, drivers are more likely to respect traffic laws. They're aware of the wider implications, such as the need to respect the rights of others, the risk of injury, or the consequences of causing an accident. Educated, critically-thinking societies tend to produce drivers who make wiser decisions, leading to safer roads for all."

I thought the law was fine but enacting it is difficult -how do you know if the tall woman with the deep voice using the Ladies is a woman without inspecting her privates

Tall women with deep voices are generally very easily distinguished from men without "inspecting their privates".

Noting in passing that it is generally men who want to access women's spaces, rather than other women, who seem to be obsessed with "genital inspections".
