The efforts of multicultural states to promote political and legal changes in the field of public administration and services in order to create the conditions for a qualified common life, reveal the necessity of a democratic political space to be supported by a public reform based on pluralist and participatory democracy, and the experience in such states provide valuable benefits to states with similar problems. This study observes how, in Switzerland, Spain, Canada, and Malaysia, the differences in the role that federal public administration, public policy, and bureaucratic representation play in building a common life, and the representation and common public participation conventions of the political community shaped by social, cultural and economic diversity in structuring two or more constituents are tied in terms of the the policy-making process.
