Regulatory Impact Assessment (RIA) – one of the tools of evidence-based policy-making – provides the opportunity to analyze the positive and negative effects of regulatory and non-regulatory measures. Not only the executive branch but also the legislature has a vital role in developing a country’s regulatory practice. Involvement of the parliament in the RIA process may be limited to passive participation – by checking the quality of RIAs carried out by the executive; or may imply active participation – by performing RIAs both for its own and the executive’s legislative initiatives.
In the present publication, the parliamentary practice of RIA in different countries is discussed:
- short information on each country’s legislative body is presented;
- a level of their involvement in both ex-ante and ex-post assessments is indicated;
- parliamentary and independent entities, who are participating in this process, are listed.
