A formal group of experts brought together on a regular basis to debate matters within that sphere of expertise, and with advisory powers to government. For example, Canada has a 'Standards Council of Canada" which debates and proposes standards policies and is able to make recomendations to the government of Canada. It can be contrasted with a commission which, although also a body of experts, is typically given regulatory powers in addition to a role as advisor to the government.
