Retired appeal court judge Sir Patrick Coghlin will chair a public inquiry into the botched energy scheme that could cost taxpayers £490m.

Finance Minister Máirtín Ó Muilleoir said the judge would be "unflinching in his pursuit of the truth and scrupulous in his analysis of the evidence".

Sir Patrick will be supported by two panel members and, if needed, assessors from outside Northern Ireland.

He would begin gathering papers on 1 February, said Mr Ó Muilleoir.

"By getting to the truth of the RHI scandal, this inquiry team will... go some way to rebuilding the shattered public confidence in the institutions," he said.

The inquiry is expected to report its findings within six months.

The RHI scheme was intended to increase the creation of heat from renewable sources.

However, businesses have been receiving more in subsidies than they are paying for renewable fuel and the scheme became majorly oversubscribed.

The fallout from the scandal surrounding the scheme, which is approximately £490m over budget, resulted in the resignation of Sinn Fein's deputy first minister, Martin McGuinness, the collapse of Stormont's institutions and the calling of snap elections on 2 March.

Earlier on Tuesday, a judge issued an interim injunction preventing the publication of hundreds of names of RHI claimants.

The finance minister told the Assembly the areas the inquiry will investigate will be wide-ranging, including:

The development and roll-out of the RHI scheme by the then Department of Enterprise Trade and Investment

The signing off of the scheme by the then Department of Finance

The issue of cost controls and tariffs

The delay in implementing cost control measures before November 2015, which lead to the spike of autumn 2015

The closure of the scheme in February 2016

Mr Ó Muilleoir said the inquiry would have the power to compel witnesses and evidence.

He said Sir Patrick would have absolute control over the scope and execution of the Inquiry, which would be entirely independent.

No decision has yet been made on the venue for the inquiry, and no details were given on its anticipated cost.
