Consultation decision reports: did responses change anything?

A consultation that produced no evidence of influence on the final decision is not genuine consultation. Decision reports must do more than summarise what respondents said. They must show which findings were treated as material, what changed because of them, and why others were set aside. Without that evidential trail, organisations cannot defend their process in scrutiny or judicial review.

What is a decision report expected to prove?

A decision report is the formal record that shows how consultation evidence entered the decision-making process. It must go beyond summarising themes. It must identify which findings were treated as material, how they were weighed against other evidence, whether they altered the preferred option, and why some findings were set aside.

This distinction matters because a consultation analysis report and a decision report are not the same document. An analysis report can describe what respondents said. A decision report must show what decision-makers did with what respondents said. The UK Government Consultation Principles require departments to explain the responses received and how those responses informed policy. Without an evidential chain connecting findings to decisions, there is no documentary basis for concluding that consultation informed policy rather than merely accompanied it.

Why does “we considered all responses” fall short?

The phrase appears in decision reports with striking regularity. It is also, on its own, almost worthless as evidence.

Accountability depends on reasons, not assertions. A report that states responses were considered gives an external reviewer nothing to test. An elected member, auditor, ombudsman, regulator or court cannot evaluate a claim that is not supported by reasoning. That is not a procedural nicety. It is the threshold for reviewability under administrative law.

Think of it as five levels of evidence, each stronger than the last:

• Responses were received
• Themes are summarised
• Decision-makers state that themes were considered
• Specific changes are linked to specific consultation findings
• Reasons are given for accepting some findings and rejecting others

Only the fourth and fifth levels allow an independent reviewer to test whether consultation actually influenced the outcome. The first three are compatible with a process that collected responses and then proceeded regardless.

Empirical evidence reinforces why this matters. A review of 183 NICE consultations found that changes were made after 74.3% of consultations, covering recommendations, safeguards, wording, evidence sections and implementation requirements. If amendments occur in roughly three-quarters of consultations, a decision report that contains no explanation of what changed may be omitting a substantial part of the decision-making record.

What does a robust evidence trail actually look like?

The Scottish Government provides one of the clearest published models. Its consultation guidance uses a four-stage framework that makes the evidence trail explicit:

• We Asked: the consultation proposition
• You Said: the consultation findings
• We Did: the decision taken
• Why: the reasoning linking findings to decision

The fourth element is the one most commonly missing from decision reports in practice. Without it, a reader can see correlation but cannot establish causation. The report may show that responses arrived and that a decision followed. It cannot show that the decision was shaped by the responses.

Ofgem has committed to the same standard from a regulatory direction. Its published consultation approach commits not merely to acknowledging or summarising responses but to demonstrating how they shape policy thinking when decisions are issued. That is the commitment that distinguishes genuine post-consultation accountability from process compliance.

A decision report written to this standard should allow any independent reviewer to answer four questions: which consultation findings mattered; what changed because of them; what did not change despite them; and why. If the document cannot answer all four, the evidential trail is incomplete.

What does this mean for practitioners managing a live decision?

The decision report is not an afterthought. It is part of the consultation design. If the process is not structured from the outset to capture which findings influenced which decisions and why, the report cannot be written retrospectively with credibility.

Practitioners should test their decision reports against the Gunning principles, the established legal test for fair public consultation in the UK, confirmed by the Supreme Court in R (Moseley) v London Borough of Haringey [2014] UKSC 56. The fourth Gunning principle requires that consultation responses receive conscientious consideration. A report that cannot show the mechanism of that consideration does not satisfy the test.

The audiences for a decision report extend well beyond the original decision-maker. Scottish Government guidance notes explicitly that consultation outputs will be used by legislatures, scrutiny committees and external bodies. The Cabinet Office Consultation Principles confirm that consultation should facilitate scrutiny. A report written only for internal purposes, without the reasoning a scrutiny committee or a court would require, is a report that has not been written for its full audience.

The practical implication is straightforward. Build the evidential trail as the analysis proceeds, not after the decision is made. Record which findings were treated as material and why. Record what changed and what did not. Record the reasoning. A report that can answer those questions demonstrates genuine consultation. One that cannot is a liability.
