Abstract

Auer deference holds that reviewing courts should defer to agencies when the latter interpret their own preexisting regulations. This doctrine relieves pressure on agencies to undergo costly notice-and-comment rulemaking each time interpretation of existing regulations is necessary. But according to some leading scholars and jurists, the doctrine actually encourages agencies to promulgate vague rules in the first instance, augmenting agency power and violating core separation of powers norms in the process. The claim that Auer perversely encourages agencies to “self-delegate”— that is, to create vague rules that can later be informally interpreted by agencies with latitude due to judicial deference—has become increasingly influential. Yet, surprisingly, this self-delegation thesis has never been tested. This Article scrutinizes the thesis empirically using an original and extensive dataset of the texts of federal rules from 1982–2016. My linguistic analysis reveals that agencies did not measurably increase the vagueness of their writing in response to Auer. If anything, rule writing arguably became more specific over time, at least by one measure, despite Auer’s increasing prominence. These findings run against common wisdom, but they should not be at all surprising. The self-delegation incentives thesis depends on a model of agency behavior that is inconsistent with what is known about the institutional pressures and cognitive horizons that cause agencies to pursue clarity in rule writing. By revealing the failures of theoretical predictions about Auer, this Article more generally draws attention to the need to test behavioral theories of administrative law against empirical reality before unsettling settled law.
