Changes

In ''[[Gibbons v. Ogden]]'' (1824), the [[Supreme Court]] interpreted the [[Commerce Clause]] to include virtually any [[business]] activity between two or more [[state]]s.  This greatly reduced the [[power]] of [[state]]s to regulate [[commerce]].

Now, much [[legislation]] by [[Congress]] is justified based on the [[Commerce Clause]].  For example, [[civil]] [[rights]] [[legislation]] banning [[discrimination]] in places of public accommodation (e.g., hotels, [[restaurant]]s, [[train]]s, [[airplane]]s) is based in the [[Commerce Clause]].  This was upheld by [[Heart of Atlanta Motel v. United States]] (1964).  Since almost anything affects [[commerce]], it is difficult to find many limits on [[federal]] [[power]] anymore.
