On October 23-24, 2018, CLDP and ITA conducted a two-day workshop on public consultation best practices for approximately 65 representatives of Salvadoran trade ministries responsible for citizen participation in addition to representatives from academia and the private sector. Additionally, representatives from several Honduran ministries participated as Honduras works to develop a framework for notice and comment procedures. The workshop served as a foundation to uniformly instruct the ministries on the intricacies of various public consultation mechanisms and institutionalize good regulatory practices as the ministries prepare to comply with the mandatory 15-day notice and comment process required by the Salvadoran Administrative Procedures Law in February 2019. Compared to other countries in the region, El Salvador has the greatest momentum toward reforming its public consultation procedures. As such, strengthening the Salvadoran government’s understanding of international best practices for public consultation will benefit the region by building momentum and serving as an example of what the remaining countries can work toward. CLDP and ITA called upon the expertise of several interagency experts with extensive experience with public consultation, particularly the notice and comment rulemaking process. The experts provided an overview of the legal underpinning of public consultation, assessed duration determinations for consultation processes, shared methodologies for reviewing and responding to comments received, and discussed whole-of-government approaches to improving transparency and governance mechanisms. Additionally, the experts walked through illustrative examples that showcased the consultation process from start to finish. The workshop increased El Salvador and Honduras’ understanding of notice and comment processes within an international trading scheme. Capacitating El Salvador and Honduras on public consultation mechanisms is part of CLDP and ITA’s workplan in Central America to help the region meet its WTO commitments.
