The agency charged with reining in the power of government is to investigate the way public bodies are releasing information as citizens complain of being shut out.
The Office of the Ombudsman is to begin its own investigation into the way the public service is responding to the Official Information Act as allegations are made of a "paralysis of democracy".
The office is struggling to cope with a large increase in complaints from the public who have sought help.
Deputy Ombudsman Leo Donnelly has begun writing to those who have complained saying it doesn't have enough staff to handle the work load.
In response to a complaint from The Herald, Mr Donnelly said the office had 450 complaints it had been unable to assign to investigators because of the volume of work.
