This panel will bring together the editors and contributors to Proportionality: New Frontiers, New Challenges (2017). The panelists will discuss future directions for proportionality doctrine and scholarship, such as whether carefully designed and limited doctrines of proportionality can improve judicial decisionmaking, how proportionality doctrine is applied in different jurisdictions, its role in constitutionalism outside of the courts, and whether the principle of proportionality actually advances or detracts from democracy. In addition to those listed below, other contributors to the volume may participate in the discussion.
