“The decision to allow a case to continue (e.g., by denying a motion to dismiss) might hinge on predictions about what will happen at the next stage (e.g., discovery) and how events at that stage will influence application of later screening standards (e.g., summary judgment). These interdependencies suggest that a rulemaker choosing between a relatively strict or lenient standard for termination/continuation decisions cannot focus solely on the supposedly essential characteristics of a particular litigation stage. Instead, whether a screening rule should be strict or lenient depends in part on the strictness or leniency of prior and subsequent screening rules.” University of Minnesota Law School Associate Professor Allan Erbsen, blogging about a Harvard Law Review article authored by Louis Kaplow.
