ETI-4: Inquiry Cost Transparency

Not accepted · Not Accepted

Recommended

In reporting the cost of a public inquiry Scottish Ministers should report its net cost to the public purse, after discounting expenditure already incurred on accommodation, staff and other resources, as well as the total cost appearing in the accounts of the sponsor department.

Since then (summary written by this site)

In November 2023, Màiri McAllan, Cabinet Secretary for Transport, Net Zero and Just Transition, stated that she did not agree with the recommendation to present only net inquiry costs less accommodation and staff, adding that "Full transparency on costs and publication of them are in the public interest" (Màiri McAllan response, Nov 2023). The record holds no update since the Scottish Government's response of November 2023 (Màiri McAllan response, Nov 2023).

Evidence & impact

AI-generated · 26 Mar 2026
The Edinburgh Tram Inquiry, chaired by Lord Hardie, examined the planning and construction of Edinburgh's tram system, which experienced significant cost overruns and delays. The inquiry published 24 recommendations in August 2023 focusing on project governance, management practices, and legal reforms.

The Scottish Government accepted 14 recommendations (58%), accepted 7 in principle (29%), and placed 3 under consideration (12%). In its November 2023 response, the Government stated that enhanced procedures for documentation management had been embedded within government and that guidance for establishing inquiries was already in development. The Government noted its commitment to collaborative working through the Verity House agreement, whilst maintaining that responsibility for project delivery remains with councils.

City of Edinburgh Council's Chief Executive reported to the Transport and Environment Committee in November 2023, recommending acceptance of several recommendations. Council Leader Cammy Day acknowledged that "serious mistakes were made in the construction of the original tram line" and noted that processes implemented since the original project had helped deliver the successful Trams to Newhaven extension.

The Council reported that scrutiny of ALEOs had "significantly improved" following reviews in 2012 and 2016, resulting in formalised observer roles and increased committee scrutiny. Training on the Member/Officer Protocol was being delivered to senior officers to clarify the distinction between officer and councillor roles.

Three recommendations regarding civil damages provisions and criminal offences for misleading evidence to inquiries remain under consideration by the Scottish Government, which noted that existing remedies may already exist under delictual liability and fraud law.

Whilst both the Scottish Government and City of Edinburgh Council provided initial responses accepting most recommendations, published evidence of specific implementation actions remains limited for many recommendations, particularly those relating to project management expertise requirements, governance structures, and stakeholder co-location practices.
