There is much confusion around what form any future inquiry into the Renewable Heat Incentive scheme might take.
Here are some of the options:
Public
The goal of the non-executive parties, a public inquiry would be the most transparent investigation, with every “jot and tittle” being aired in public. The power to compel witnesses would also be in effect; leaving no one immune from questioning. Witnesses would be questioned in a court-style setting, with the public and press allowed to witness the exchanges.
Among the issues Sinn Féin has called for a public inquiry into is a proposed gold mine in Co Tyrone.
Independent
The DUP and now Sinn Féin are now both calling for an independent inquiry, which itself can come in many different forms.
Sinn Féin has supported an "independent, time-framed, robust and transparent investigation" whereas the DUP have said there is a need for a probe into RHI "free from partisan political interference".
However, the terms of reference for such an investigation are unclear. Whether or not it would have to power to compel witnesses or evidence, or how transparent it would be, remains to be seen. Crucially the investigation would be carried out by a legal figure in private.
A previous independent probe into Peter Robinson’s financial dealings in 2014 was the subject of criticis, as it was not published upon its completion.
Internal
Perhaps the least effective in terms of scope and power, an internal inquiry does not have the power to compel witnesses or evidence, it can only ask for such.
The Public Accounts Committee is currently conducting an internal inquiry into the RHI scandal, however this has been sidetracked in recent months due to the ongoing crisis.
On January 16, Sinn Féin are set to table a motion calling for an independent inquiry in the RHI scheme and for the first minister to step aside while it takes place, however the SDLP and Alliance will not support the motion.
