CrowdLaw is the practice of using technology to tap the intelligence and expertise of the public in order to improve the quality of lawmaking. Around the world, there are already over two dozen examples of local legislatures and national parliaments turning to the Internet to involve the public in legislative drafting and decision-making. These ambitious crowdlaw initiatives show that the public can, in many cases, go beyond contributing opinions and signing petitions online to playing a more substantive role, including: proposing legislation, drafting bills, monitoring implementation, and supplying missing data. Through such processes, the public becomes collaborators and co-creators in the legislative process to the end of improving the quality of legislative outcomes and the effectiveness of governing.
