The Department of Justice and Equality has published a set of Guidelines setting out a step-by-step process for conducting a disability impact assessment, which fits within the broader regulatory impact assessment (RIA) framework.  Disability proofing of all substantive proposals requiring Government approval is mandatory.  The guidelines have been developed by the Department of Justice and Equality, the Equality Authority and the National Disability Authority to assist officials in Government Departments who are carrying out disability proofing of memoranda for submission to the Government.  A copy of the booklet is available to download here.
