Westminster (Britain Today News) July 22, 2026 – The House of Lords Constitution Committee has today published a call for evidence for its inquiry into the UK’s constitutional safeguards, opening the door for legal experts, academics, civil society groups and members of the public to shape the direction of a review that could influence how Britain’s unwritten constitution is protected in the years ahead. The Committee is inviting interested individuals and organisations to submit their views on this issue, with the deadline for written evidence submissions set at 9am on Monday, 28 September 2026.

What Is The Lords Constitution Committee Inquiring Into?

The House of Lords Constitution Committee is conducting an inquiry into the UK’s constitutional safeguards. According to the Committee’s own published terms, the inquiry will seek to understand the extent to which the UK’s constitutional democracy is under threat. Within this context, it will seek to identify the constitutional safeguards that exist within the UK system, and understand the most significant strengths, weaknesses and vulnerabilities in how they operate.

The scope of the inquiry is broad by design. Rather than focusing on a single institution or a single piece of legislation, the Committee has framed its review around the entire architecture of safeguards that underpins the UK’s constitutional settlement — an architecture that, unlike in many other democracies, is not set out in a single codified document but is instead built from statute, convention, precedent and institutional practice.

Why Has The Committee Launched This Inquiry Now?

The Committee has not published an extensive public rationale alongside the call for evidence beyond the terms of reference themselves, but the framing of the inquiry signals a concern that the resilience of the UK’s constitutional arrangements can no longer be taken for granted. The Committee’s stated ambition is to identify ways in which the UK’s network of safeguards can be made more effective, a phrase that implies an acknowledgement that the current system may contain gaps or weaknesses worth addressing.

This inquiry does not sit in isolation. The Constitution Committee has, in recent years, examined related territory, including the responsibilities of the executive for overseeing the constitution and the state of the rule of law in the UK. The new inquiry into constitutional safeguards appears designed to draw together and build upon the themes explored in that earlier work, while casting a wider net across the full system rather than any one part of it.

What Is The Aim Of The Inquiry Into Constitutional Safeguards?

The Committee’s own description of its objectives sets out a clear, staged approach. In conducting this inquiry, the Committee expects to identify areas that would benefit from further inquiry, and will therefore form the basis of future Committee work. This suggests the current inquiry is intended, at least in part, as a scoping exercise — one that will map the landscape of constitutional protections before deciding where the Committee’s attention should be directed next.

The three core aims, as set out by the Committee, are to establish whether the UK’s constitutional democracy is under threat, to catalogue the safeguards that currently exist, and to assess how well those safeguards are functioning. Only once that picture has been established does the Committee intend to consider what further scrutiny or reform might be required.

How Can Individuals And Organisations Submit Evidence?

The Committee invites interested organisations and individuals to submit written evidence to the inquiry. The call for evidence has been made publicly available, and submissions are welcomed from a wide range of contributors, including constitutional lawyers, political scientists, civil servants, former officeholders, campaign groups and ordinary members of the public with relevant insight to offer.

As is standard practice for House of Lords select committee inquiries, written evidence forms the backbone of the process. Submissions received during the call for evidence period are typically published and may be drawn upon in subsequent oral evidence sessions, where the Committee questions witnesses directly, and in any final report the Committee chooses to produce.

What Is The Deadline For Written Evidence Submissions?

The deadline for written evidence submissions is 9am on Monday, 28 September 2026. This gives prospective contributors a window of a little over two months from the date of publication to prepare and submit their responses. Given the breadth of the subject matter, the Committee has allowed a comparatively generous period for evidence gathering, reflecting the complexity of the questions being posed and the range of expertise the Committee is hoping to draw upon.

Organisations and individuals wishing to contribute are expected to follow the formal submission process set out by the Committee at the time of publication, in line with standard House of Lords procedures for select committee inquiries.

What Key Questions Has The Committee Asked Contributors To Address?

The Committee welcomes written submissions on any aspect of this topic, and particularly on the following questions. It is not necessary to answer all the questions, giving contributors flexibility to focus on the areas where they have the most relevant expertise or experience. The questions posed are:

• Is the UK’s constitutional democracy under threat? If so, why?
• How could potential threats to the constitution be mitigated?
• What safeguards exist to protect the UK constitution?
• How effective are the UK’s constitutional safeguards? Where do the vulnerabilities lie?
• Who are the key guardians of the integrity of the UK’s constitution? What formal or informal powers do they have? Who guards the guardians?
• How do the UK’s constitutional safeguards compare to those in other jurisdictions? What are the comparative strengths and weaknesses of the UK’s system?
• How has the landscape of constitutional safeguards changed over time? Which safeguards have become both more or less significant, and why?

Taken together, these questions span the theoretical (whether a threat exists at all), the practical (what mechanisms currently exist and how well they work), the institutional (who is responsible for defending the constitution), the comparative (how the UK measures up against other democracies) and the historical (how safeguards have evolved).

Is The UK’s Constitutional Democracy Under Threat, According To The Committee?

The Committee has not pre-judged this question in its call for evidence — indeed, it is the first and most fundamental question put to contributors. By asking

“Is the UK’s constitutional democracy under threat? If so, why?”

as the opening question of the inquiry, the Committee is signalling that it wants evidence-based answers rather than starting from an assumption that a threat exists.

This approach is consistent with the Committee’s role as a scrutiny body rather than a campaigning one. Its remit, as a House of Lords select committee, is to examine the constitutional implications of public bills and to investigate broader constitutional issues, drawing on expert testimony rather than pre-existing political positions. The inquiry’s design reflects that same evidence-first approach, leaving it to those submitting views to make the case, one way or another, as to whether the constitution is genuinely at risk.

What Safeguards Currently Exist To Protect The UK Constitution?

Identifying the existing safeguards is one of the central tasks the Committee has set for this inquiry. As the Committee’s own terms note, it will seek to identify the constitutional safeguards that exist within the UK system, and understand the most significant strengths, weaknesses and vulnerabilities in how they operate.

The UK’s constitution, being uncodified, relies on a patchwork of statute, convention, judicial oversight, parliamentary procedure and institutional checks rather than a single written charter. This inquiry appears designed to take stock of that patchwork in its entirety — asking not just what safeguards exist on paper, but how effectively they function in practice, and where the gaps between formal power and practical accountability might lie. The question of “who guards the guardians” — posed directly among the Committee’s seven questions — points to a particular interest in accountability mechanisms for those who themselves hold constitutional responsibilities.

How Will The Findings Of This Inquiry Shape Future Committee Work?

Perhaps the most significant signal in the Committee’s own framing is its stated intention to use this inquiry as a foundation for further work. In conducting this inquiry, the Committee expects to identify areas that would benefit from further inquiry, and will therefore form the basis of future Committee work. This positions the current call for evidence not as an end point, but as the opening phase of a longer-term programme of constitutional scrutiny.

Should the evidence gathered point towards specific vulnerabilities — whether in the role of the Prime Minister, the operation of parliamentary conventions, the independence of the judiciary, or any other part of the system — it is likely the Committee will use those findings to justify launching more targeted inquiries in future, potentially culminating in formal reports and recommendations to the Government, as has been the Committee’s practice in previous inquiries.

What Is The House of Lords Constitution Committee?

The Constitution Committee is a House of Lords select committee tasked with examining the constitutional implications of public bills referred to it and investigating broader constitutional issues that fall outside the scope of specific legislation. It carries out its longer investigative work by choosing a subject, engaging specialist advisers, inviting written submissions, and taking oral evidence from a range of witnesses, including government ministers, before publishing a report containing recommendations aimed principally at the Government.

Under long-standing practice, the Government is obliged to produce a formal written response to the Committee’s recommendations, and the report and government response are then typically debated in the House of Lords. This established process gives the current inquiry into constitutional safeguards a clear potential pathway: from call for evidence, through oral hearings and a published report, to a formal government response and parliamentary debate.

What Happens Next For Those Wishing To Contribute?

With the call for evidence now open and the clock running towards the 28 September 2026 deadline, the coming weeks are expected to see a range of submissions from constitutional experts, legal bodies, academic institutions and civil society organisations, many of which have engaged with previous Constitution Committee inquiries on related themes such as the rule of law and executive oversight of the constitution.

Once the written evidence has been gathered and reviewed, the Committee is likely to move towards oral evidence sessions, inviting selected witnesses to expand upon the issues raised in submissions. Given the scale of the subject matter — spanning the entirety of the UK’s constitutional safeguards — the process is likely to unfold over a considerable period, with any eventual report expected to draw heavily on the breadth of evidence submitted during this initial phase.

For now, the Committee’s message to prospective contributors is straightforward: submissions are welcome on any aspect of the UK’s constitutional safeguards, and it is not necessary to answer every question posed in order to take part in shaping this significant piece of parliamentary scrutiny.
