Baude, et al. v. Heath, 538 F.3d 608 (7th Cir. 2008)

(state regulation requiring residents to first make fact-to-face contact with wine merchant before placing phone or online orders upheld as constitutional because effect on interstate commerce negligible; but, regulation prohibiting vintners from acting as their own wholesaler struck down as unfair burden on out-of-state sellers even though facially neutral).
