Legitimacy by Design

Legitimacy by Design is a developing research-practice approach for examining whether public-facing or socially relevant systems structurally support claims of fairness, accessibility, accountability, intelligibility, recognition, and contestability.

It is associated with Public Layer Lab’s work on digital and administrative systems of public or social importance, public accountability, and the design of systems that shape access to public or civic functions.

Why it is needed

Public-facing and socially relevant systems often make public claims. They may be described as fair, transparent, inclusive, accessible, accountable, trustworthy, participatory, user-centred, or rights-preserving.

These claims are important, but they are not automatically supported by the existence of a policy, interface, process, or digital service. A system may appear transparent without being understandable. It may invite participation without giving people meaningful influence. It may provide formal access while making practical access difficult. It may distribute responsibility across many actors in ways that make challenge, correction, or accountability hard to locate.

Legitimacy by Design starts from a simple question:

Does the design of the system actually support the public claims being made about it?

A simple illustration

A participation platform may claim to make a planning process more democratic. Legitimacy by Design would not only ask whether comments can be submitted. It would also ask whose input becomes visible, how summaries are produced, whether objections are traceable, where responsibility for decisions sits, and whether people can see how their participation mattered.

An AI-assisted case process may claim to improve speed or consistency. The relevant question is not only whether the model performs well. It is also whether affected people can understand the role of the tool, whether human review remains meaningful, whether errors can be corrected, and whether responsibility is still locatable.

A cooperative, NGO, or social enterprise may use a digital tool for participation, membership, allocation, reporting, or accountability. Legitimacy by Design would ask whether the system’s categories, permissions, records, summaries, and review routes support the claims the organisation makes about fairness, accessibility, participation, or accountability.

What it examines

Legitimacy by Design focuses on the structural conditions that make systems fair, accessible, understandable, challengeable, and accountable.

It examines questions such as:

• who or what a system recognises;
• how people, organisations, claims, documents, or statuses become legible;
• how access is organised in practice;
• what users or affected publics need to understand;
• where responsibility is located;
• how errors, exclusions, or mismatches can be corrected;
• whether participation creates meaningful agency or only procedural visibility;
• whether burdens are fairly distributed or shifted onto citizens, organisations, communities, or affected publics;
• whether public claims are supported by the system’s actual design, documentation, governance, and fallback arrangements.

Core diagnostic concerns

The approach is organised around several recurring concerns.

Recognition

Does the system recognise the people, organisations, situations, claims, or forms of evidence that matter?

Recognition is not only a social or political question. It can also be shaped by forms, categories, identity systems, registers, eligibility rules, data structures, and administrative routines.

Access

Can people or organisations actually use the system, route, or process in practice?

Access is not only about whether something formally exists. It also concerns language, cost, documentation, digital ability, institutional knowledge, support channels, error handling, and the burdens placed on users.

Intelligibility

Can affected people understand what is happening, what is expected of them, and why a decision, classification, or process matters?

A system may publish information without making it usable. Intelligibility asks whether information supports understanding, action, correction, and accountability.

Contestability

Can errors, exclusions, mismatches, or disputed outcomes be challenged and corrected?

Contestability requires more than a formal complaint route. It depends on whether people can identify what happened, who is responsible, what evidence matters, and how repair or review can realistically take place.

Burden

Who carries the burden when the system is hard to use, fails, misrecognises someone, or produces unclear outcomes?

Legitimacy by Design pays attention to whether administrative, technical, evidentiary, or interpretive burdens are proportionate and fairly distributed.

How it can be used

At this stage, the approach may support work such as:

• examining whether a proposed system structurally supports its public claims;
• identifying gaps between public values and system design;
• structuring questions for further legal, policy, technical, accessibility, or governance review;
• informing procurement, design, review, accountability, or public-explanation conversations;
• preparing examples, notes, or Lab materials that make public-system and social-sector system questions easier to see.

It is designed to complement, not replace, legal, technical, policy, accessibility, security, and domain-specific forms of review.

Current status

Legitimacy by Design is currently a developing research-practice approach. Its concepts and diagnostic structure are being refined through research, public explanation work, and application to selected cases and system types.

Future versions may include public notes, examples, assessment templates, or longer publications. These will be published only when their claim level can be stated responsibly.

Relation to Public Layer Lab

Public Layer Lab provides the institutional home for developing, explaining, and carefully testing approaches such as Legitimacy by Design.

The purpose is not to create a fixed doctrine or universal checklist. The aim is to support clearer public reasoning about systems that increasingly shape fairness, access, recognition, accountability, and participation in public and civic life.
