OBS_VALUE: Regulations from the central government that establish or modify procedures need to have a prior public consultation procedure. General regulations of the Executive Power must be consulted to other public institutions and to entities representing general interest or corporate interests who could be affected by the regulation (for a period of ten days), unless there are reasons of public interest. Bills of law are discussed and approved in Congress in publicly held meetings. There is the possibility to comment to all interested persons before a law is enacted (including foreign suppliers).
