How often courts cite the case defining “regulation”
Court decisions citing the opinion that defined “regulation” — 219 in all, by decade. Counts are citations to the defining case as a whole, not verified uses of the term. The dip in the most recent years is a data-coverage gap, not a real trend — our corpus holds fewer opinions from the latest years.
