Weakening the Plaintiff’s Case Without Strengthening the Defendant’s

The reason model of precedential constraint is supposed to generate a stricter doctrine than the minimalist result model. In the standard setting in which these models were originally formalized, that is exactly what we find. Surprisingly, however, in the more complex dimensional setting, the models become indistinguishable. In this paper, we provide an illuminating explanation of the collapse. We also shed light on recent proposals to modify the reason model, or the underlying dimensional setting, in order to avoid it. Finally, we show how the models can be made to collapse even in the simpler standard setting.
