Notes of Decisions

Exclusion of on-premises signs from regulation as outdoor advertising signs is not content-based discrimination against noncommercial speech. Outdoor Media Dimensions, Inc. v. State of Oregon, 150 Or App 106, 945 P2d 614 (1997), aff'd 331 Or 634, 20 P3d 180 (2001)

Imposition of content-neutral regulatory requirements does not infringe on protected speech. Outdoor Media Dimensions v. Department of Transportation, 340 Or 275, 132 P3d 5 (2006)
