Control of Mercury (Enforcement) (Amendment) Regulations 2025

Lord Morrow Excerpts

Thursday 30th October 2025 Lords Chamber

[Lord Bourne of Aberystwyth (Con)]

My Lords, I will make a briefer speech, not on the constitutional aspect of this but on the dentistry aspect. I thank the Minister for introducing this, and indeed the noble Baroness for moving her amendment. I do recognise that there is a very important constitutional issue as well. The amalgam ban will come in in 10 years’ time to Northern Ireland. As regards the rest of the United Kingdom, clearly, EU rules do not apply, but the supply and price chains have a massive effect, so there is an issue about the availability of mercury and amalgam within the next period.

The Minister said quite correctly that amalgam fillings are cheaper, and that treatment is far longer for alternatives. It is also worth saying that they last longer and do not need replacing as often. So there is a very real issue about the cost going forward of alternatives. Research and development is needed within the dentistry profession, sponsored and helped by the Government, to look at alternatives to mercury. We also need investment in better oral health.

Without those things, I fear that, within the next 10 years, irrespective of the constitutional aspects we are talking about, there is a real concern for dentistry and oral health not just in Northern Ireland—although, admittedly, it will hit there harder—but in the rest of the United Kingdom. I hope the Minister will be able to address that. If she does not have specific details, I would appreciate it if she could write.

[Lord Morrow (DUP)]

My Lords, I am pleased to support the amendment from the noble Baroness, Lady Hoey. There is no doubt that one of our greatest national institutions is the NHS. The people of the United Kingdom have in the past been exercised about the possibility that those whom they elect might tamper with it, notwithstanding their accountability to the electorate. Imagine, then, the concern that attends the prospect of having a key aspect of the NHS placed in jeopardy by the politicians of a foreign country who are not accountable to you. That is the plight that befell UK citizens living in Northern Ireland when the EU Parliament voted EU Regulation 1849 in 2024.

Being disenfranchised, which has already been mentioned, in some 300 areas of law is bad enough. But when the laws give the foreign legislators the power to strike down any aspect of one of our great national institutions, the justice of that disfranchisement is completely intolerable. It is an indignity to which the people of England, Wales and Scotland should never be subjected: why, then, the people of Northern Ireland?

In this context, I was aghast to listen last week to the Secretary of State for Northern Ireland, the right honourable Member for Leeds South, giving evidence to the Northern Ireland Affairs Select Committee in another place that the Government had “solved” the amalgam problem. That was just quite extraordinary, to put it mildly. A piece of legislation has been imposed on part of the UK by a legislature in which it is not represented, and which places a key component of one of our greatest institutions in jeopardy. Rather than standing as citizens, we are subjected to the humiliation of being taken as supplicants to the bar of the grace and favour of a foreign Executive to see what crumbs they might be persuaded to toss from their gilded table.

To make matters worse, we are expected to be thankful, grateful and accepting of it, even though we have no more made the concession than the original legislation. Whatever happened to self-respect? Whatever happened to the United Kingdom? We are then forced to confront the consequences of the fact that, rather than being treated as legislators, we are taken for dumb supplicants in the development of the alternative provision through the fact that this alternative provision further alienates us from the rest of our home country.

Under the Commission notice, from 1 July 2026 it will be illegal to produce amalgam in Northern Ireland and it will have to come from Great Britain. This introduces two compulsions. First, in order to have amalgam, Northern Ireland must buy it from GB because it is not allowed to be produced in Northern Ireland. Secondly, its movement from Great Britain to Northern Ireland is subject to the imposition of an international customs border, cutting the United Kingdom in two. This means that, from July 2026, it will only be possible to take amalgam across the red lane as if moving it to a foreign country.

In a context where the number of traders selling goods from GB to Northern Ireland is falling all the time because of the cost of having to negotiate the border, what certainty do we have that anyone in GB will be ready to sell dental amalgam to Northern Ireland from July 2026 until December 2034? While UK citizens living in England, Wales and Scotland will be protected from this uncertainty, apparently it is fine not to afford the same protection to UK citizens in Northern Ireland.

We must confront the fact that the regulations before us today rest on a very uncertain foundation. The fundamental problem is that, when interpreting the relevant EU law to which these regulations seek to relate, the European Court of Justice will have to confine its interpretation to the law. It will have to ask what EU Regulation 2024/1849 means in relation to Northern Ireland and not what the EU Commission notice means, because, rather than being the law, the latter is simply the Commission’s rather extraordinary interpretation of EU Regulation 2024/1849.

In her response, the Minister might be tempted to say that there are other examples of Commission notices performing the same kinds of feats as that which underpins the regulations before us today. I can locate only two, both of which come with the heading “DISCLAIMER” and seek to interpret the relevant legislation to the point of changing its effective meaning. Interestingly, they both relate to the Irish Sea border and attempts to interpret one’s way out of earlier problems. One relates to human medicines and the other to veterinary medicines.

Finally, could the Minister explain why it is acceptable to bring legislation to your Lordships’ House that does the following? First, it testifies the disfranchisement of the people of Northern Ireland in relation to key aspects of the NHS; secondly, it further alienates us from the rest of the United Kingdom through the imposition of a dental amalgam sea border from July 2026; thirdly, it presents all this on a legal foundation that relates not to EU law but to an interpretation of it that bears no relation to the actual legislation, and which could be struck down by the European Court of Justice at any time; and, fourthly, it acquiesces with the unconstitutional practice of, in effect, using the Executive to suspend laws made by this legislature.

[Lord Reay (Con)]

My Lords, I thank the Minister for introducing this debate and the noble Baroness, Lady Hoey, for her amendment. This SI addresses the implications for Northern Ireland of the Government’s decision not to follow the Minamata Convention on Mercury on phasing out the use of mercury dental amalgam fillings throughout the EU. I will say a few words on why it is concerning that the UK Government are rowing back on their Minamata commitments, and why mercury amalgam fillings, which are highly toxic, should be banned throughout the UK at the earliest opportunity.

This issue is not merely one of dentistry; it concerns public health, environmental protection and ethical responsibility. Mercury is one of the most toxic substances known to science, as the Minister readily accepted in her opening statement, and there is no safe level of exposure for humans. Studies show that mercury vapour is released continuously into the mouth from amalgam fillings, especially when we chew, grind our teeth or have old fillings removed. These vapours are inhaled, absorbed into the bloodstream and stored in the body’s tissues. Chronic exposure has been linked to neurological damage, kidney dysfunction and developmental harm in unborn children.
