In comparative constitutional law and theory, the judicial power to strike down laws has long been viewed as a powerful weapon on the judicial arsenal, because it enables courts to invalidate or nullify democratically enacted laws. In this lecture, Professor Aileen Kavanagh will argue that the strike-down is neither as strong, as central, nor as censorious as is often assumed. Situating the strike-down in its broader adjudicatory context across multiple jurisdictions, she will show that judges often stop short of striking down. Even if they decide to declare a law invalid, judges use various techniques to soften the blow of the strike-down, and narrow its temporal and legal effects. The upshot is that the strike-down is neither as final, as fatal, nor as forceful as is often assumed.
