A Stormont team to implement reforms after the 'cash for ash' scandal has yet to meet for the first time - more than six months after it was formed.
But already a new row has ignited over the Renewable Heat Incentive scheme, which toppled Stormont for three years because of the make-up of the team.
A dedicated group to examine the findings of the inquiry into the Renewable Heat Incentive (RHI) scheme was pledged in the New Decade, New Approach deal which lead to the restoration of devolution in January.
But it has emerged the sub-committee will be comprised of ministers from the two main parties which were criticised in the inquiry report, the DUP and Sinn Fein.
Sunday Life has learned it is to be chaired by SF Finance Minister Conor Murphy with First Minister Arlene Foster represented by Junior Minister Gordon Lyons of the DUP, along with other Ministers. They will also set their own terms of reference.
But Ulster Unionist and Alliance MLAs, whose parties form part of the Executive, have attacked the lack of external input with North Antrim MLA Jim Allister also tabling a series of urgent questions. UUP MLA Doug Beattie said it was an example of "poacher turned gamekeeper" since the DUP and SF were "inextricably linked" to the RHI scandal.
"It beggars belief in this new era of supposed transparency and accountability that they will set their own terms of reference and drive the agenda... Neither party should be anywhere near it," he added.
"They should at least have brought in a degree of independence to at least set the terms of reference. The fact they didn't is yet another failure."
TUV leader Mr Allister said it would do nothing to increase public confidence in the administration "which people already have little faith in.
"The fundamental finding of the inquiry was that Stormont didn't have the ability to run so complex a heating scheme. An in-house sub-committee of the same failed Executive is not the way to address the problems the inquiry uncovered." He has tabled a number of questions asking who was involved in drawing up and approving the terms of reference and whether they will be published along with its findings and a timescale.
Alliance MLA Stewart Dickson said the committee was "hardly open and transparent".
A statement on behalf of Minister Murphy said, however: "The RHI sub-committee hasn't met yet as the Executive is currently prioritising its response to the Covid-19 pandemic. It is intended that it will meet as soon as possible."
And a written response to Mr Allister from Minister Murphy said the sub-committee had yet to decide whether to publish its findings but an action plan will be drawn up when it does meet.
An earlier statement added: "The Department of Finance commissioned the independent RHI inquiry and it is therefore appropriate that it would chair the sub-committee. The membership will be Ministers as it is a sub-committee of the Executive, ensuring that all the parties are represented. The terms of reference will be agreed by the sub-committee at its first meeting and will then be published."
The RHI report said it hoped the inquiry would lead to more "transparent and effective" government in Northern Ireland to repair the "systematic shortcomings" it had identified.
