The Brennan Center uses a combination of inter-disciplinary research, innovative policy development, legislative advocacy, litigation, and communications work to win meaningful, measurable change in the public sector. We seek to devise fresh, practical, data-driven, bipartisan legal reforms backed up by high caliber, rigorous research. We publicize those ideas and communicate to voters and lawmakers the necessity of the reforms we support. We then work to ensure that lawmakers enact these new laws to advance democracy and justice. And if these laws are challenged, we defend their legality and reasonability in the courtroom. We also pursue litigation to block or overturn laws that dismantle existing protections or further restrict rights, and file friend-of-the-court briefs rich with data to inform courts of the practical effects of legal arguments.
