It is a pleasure to speak to clause 3, which brings forward the vital and long overdue changes to the way our laws treat autism and learning disabilities under the Mental Health Act. The clause responds to a persistent injustice: the inappropriate detention of autistic people and people with learning disabilities in mental health hospitals, often for years at a time, without meaningful therapeutic benefit. Those individuals are not mentally ill, yet they have too often been detained, medicated and restrained as if they were.
As the law stands, individuals with learning disabilities and autistic people can be detained both for assessment, under section 2 of the Act, and for treatment, under section 3. Notably, people with learning disabilities may be detained under section 3 when their condition
“is associated with abnormally aggressive or seriously irresponsible conduct”,
whereas that does not currently apply to autistic people. Evidence and reports show that some such detentions can be lengthy and may not always provide therapeutic benefit. That raises concerns about the appropriateness of detention on the basis of disability alone. In my time on the Health and Social Care Committee, we looked specifically at this topic and produced a report, some of which has influenced the Bill.
The clause aims to directly address the issue of lengthy detentions for such individuals. For the first time, the law will clearly define autism and learning disability—something that has not happened for 40 years. As science has moved on, legislation must follow. Autism will now be recognised as a “lifelong developmental condition” that affects perception, communication and interaction, and learning disability will be defined as “significant impairment” of intellectual functioning.
Supported by schedule 1, the clause seeks to clarify and refine that position by introducing formal definitions of “autism”, “learning disability” and “psychiatric disorder”. Crucially, it removes autism and learning disability as stand-alone grounds for compulsory treatment and detention under section 3. Instead, detention for treatment will be permitted only if a person has a co-occurring psychiatric disorder—that is, a mental disorder other than autism or learning disability. Additionally, the change applies to community treatment orders, meaning that they cannot be applied solely on the basis of autism or a learning disability. However, the Act makes it clear that the changes do not apply to people detained under part 3 of the Act who are within the criminal justice system. For that group, autism and learning disabilities with serious behavioural consequences remain grounds for detention and treatment disorders.
The Bill introduces the new term, “psychiatric disorder”, meaning any mental disorder excluding autism or a learning disability. That distinction matters because detention under section 3 of the Act—compulsory admission for treatment—will no longer be permitted solely on the basis of someone being autistic or having a learning disability. From now on, a person may be detained only if they have a co-occurring psychiatric disorder or their learning disability is associated with “serious behavioural consequences”, such as
“abnormally aggressive or seriously irresponsible conduct”.
That reflects a fundamental shift in the philosophy of the Act from using hospitalisation as a containment tool to ensuring that any detention has a clear clinical and therapeutic purpose.
This reform is rooted in the recommendations of the 2018 review of the Mental Health Act, which was led by Professor Simon Wessely, and has been championed by groups such as the National Autistic Society. It represents a more modern understanding, as we currently see things, so there are many positives—it protects people’s rights, preventing detention simply for being different, it promotes community-based care rather than institutionalisation, it modernises the law in line with current clinical understanding and it seeks to end the harm caused by prolonged non-therapeutic hospital stays, which often involving over-medication and restraint.
However, I also sound a note of caution: the clause alone will not be enough. There is rightly concern about the provision for robust community services. We risk creating legal protections that are admirable on paper but ineffective in practice. I know that the Minister appreciates this dilemma. If people cannot get the right support in the community, they will still end up in crisis, and possibly still be detained—just under a different part of the law.
There are also concerns about ambiguity. The phrase “serious behavioural consequences” may be open to a wide interpretation. Without clear guidance and training, we risk inconsistencies and even potential loopholes that could undermine the intent of this reform. I commend the Government’s intention to protect autistic people and people with learning disabilities from potentially inappropriate detentions, and to ensure that compulsory treatment is targeted to those with mental disorders warranting hospital care.
The emphasis on therapeutic benefit and the principle of least restriction aligns well with the human rights standard and the UN convention on the rights of persons with disabilities. However, I have several questions that I hope the Government will be able to address. How will clinicians reliably distinguish between behaviours arising from autism and learning disabilities and behaviours arising from co-occurring psychiatric disorders, given the complexity of presentations in this population? Is there, or will there be, clear guidance and training to support those assessments? For individuals with severe autism or learning disabilities who display challenging behaviours but do not have a diagnoseable psychiatric disorder, what alternative pathways and supports are envisaged to ensure their safety and wellbeing without resorting to detention?
On the issue of patients under part 3 of the Bill, I know the Government’s rationale for maintaining broader detention definition criteria, but will there be additional safeguards or oversight to ensure those patients are not subject to unnecessarily prolonged or restrictive detention? The removal of “social functioning” from the definition of learning disability is intended to create a clearer distinction from autism, but could the changes create any unintended legal or clinical ambiguities in practice?
The changes could introduce some unintended consequences. Previously, impairments in social function were considered part of the learning disability definition, which helped capture individuals whose social difficulties accompanied intellectual impairments. Without that, there may be legal and clinical uncertainty for people with borderline or overlapping conditions. For example, someone with moderate intellectual impairment and significant social difficulties might no longer clearly fit the learning disability definition. Similarly, autistic individuals with mild intellectual disability who experience social challenges could find their diagnosis and legal status less certain. Those ambiguities risk inconsistent assessments and potential gaps in access to appropriate care unless the Government provide clear guidance to clinicians and tribunals on how to navigate complex presentations. What plans are in place to monitor and evaluate the impact of the changes on detention rates, patient outcomes and the availability of community-based alternatives?
In closing, this is an important clause that moves us closer to a system that respects autonomy, delivers appropriate care and upholds the rights of neurodivergent people. But we must be mindful that passing this legislation must not be seen as the end of the job. As the Minister understands, it is the beginning. If we are to drive reform, the Government will need to set out the funding and workforce pathway for the services that will deliver it. We must train professionals, empower families and support voices of lived experience at every level. Only then will clause 3 deliver on its promise not just to change law, but to change lives.
I turn to schedule 1. Schedules are an important and yet often overlooked part of the legislative process. It is worth reminding the Committee that a schedule is a part of a Bill’s function, like a detailed appendix. It contains the granular, often technical amendments that give practical and legal effect to the broad principles set out in main clauses. In other words, the clause tells us what Parliament intends to do and schedules show us how it will be done: amending existing statutes, updating definitions and ensuring consistency across legal frameworks.
In this Bill, schedule 1 is particularly consequential. It does the heavy lifting of applying the reforms in clause 3 to the existing Mental Health Act 1983, especially with regard to how we treat autism and learning disabilities within the scope of mental health law. Let us be clear that the schedule is not simply technical. It is transformational in what it attempts to do. Where the 1983 Act spoke broadly of mental disorder, schedule 1 now creates a more precise legal category—“relevant disorder”—defined to include psychiatric disorder, autism and learning disability with serious behavioural consequences. That matters enormously. In fact, it is one of the key reasons for the review of this entire piece of legislation. Individuals with autism or learning disabilities have been subject to compulsory powers, including detention, as we have heard, in the absence of any co-occurring mental illness. That is a practice with which the Committee should rightly be uncomfortable.
Schedule 1 amends not only the criteria for compulsory admission under section 3, but those for guardianship, community treatment orders, tribunal discharge and even the treatment provisions in part 4 of the Act. This breadth shows that clause 3 is not merely a rhetorical shift; it is being operationalised throughout the entire Act. With such significant implications, the schedule raises serious and legitimate questions that I am sure will form the backbone of the ongoing discussions in Committee over the next few weeks.
First, what is the threshold for serious behavioural consequences? Will that be clearly defined? Without precision, we risk substituting one vague standard for another. Secondly, do the transitory provisions offer enough clarity for frontline practitioners, in particular approved mental health professionals and tribunal panels who will be making decisions in grey areas between new and old law? Again, what about the cross-border issue between Wales and England? Thirdly, given the change from mental disorder to psychiatric disorders in some sections but not others, what is the Government’s rationale for that linguistic differentiation? Is there a risk of confusion among legal and clinical practitioners? To clarify—I am happy to share this with the Minister—I went through it and there appear to be a few occasions where the definition was changed, but some areas where it was not. Now, that may be my naïve understanding as a mere shadow Minister, but I would welcome the clarification and I am happy to pass them on to the Clerks to ensure that, if we are going to update the Bill, all parts are updated. Finally, and critically, do we have the workforce, training and services in place to support this cultural and clinical shift away from paternalism towards community-based and rights-respecting alternatives?
Schedule 1 shows us that reform is not just about good intentions, but getting the detail right. It is about ensuring the law reflects modern clinical understanding and human dignity. I support the direction of travel, but I gently remind the Minister to ensure that the operational mechanisms of the schedule are tested, clarified and, where necessary, strengthened. We owe that to the individuals and the families for whom we are producing this legislation to improve their lives.
