The Inclusion/Exclusion Canon
When GW includes particular language in one place but omits it in another, it does so for a reason.
1. Dean v. U.S., 129 S.Ct. 1849 (2009):
“Where Congress includes particular language in one section of a statute but omits it in another section of the same Act, it is generally presumed that Congress acts intentionally and purposely in the disparate inclusion or exclusion.”
