Consistent ethical conduct by members of parliament can help build strong, trusting relationships between the public and the legislature. To support parliaments and civil society groups in establishing clear standards for ethical behavior, members of the Open Government Partnership’s Legislative Openness Working Group developed the Common Ethical Principles for Members of Parliament in conjunction with members of the OpeningParliament.org civil society community and the broader parliamentary community. The Common Ethical Principles draw from and seek to build on an emerging body of international norms and standards for parliaments, including the Commonwealth Parliamentary Association’s Recommended Benchmarks for Codes of Conduct Applying to Members of Parliament and the Declaration on Parliamentary Openness. The Common Ethical Principles also draw heavily on existing good practice employed by parliaments around the world. The document calls on members of parliament to, among other things, safeguard democracy and human rights, serve the public above all else, ensure public integrity, avoid conflicts of interest, carry out public duties professionally and transparently, and value diversity and political pluralism.
