More on the decision from another source. Most states didn’t follow the California ruling.
Fortunately, there is good news for shopping center owners in most states. Except for California, which still follows the rationale set forth in the Pruneyard case, and several other states such as New Jersey, Massachusetts and Colorado, which have adopted versions of the Pruneyard rationale, the majority of state court decisions since Pruneyard have protected the rights of private property owners to enact regulations governing political protests, demonstrations and similar activities at their shopping centers and have held that individuals and groups do not have the unfettered right to enter private property for the purpose of picketing, demonstrating or conducting similar types of activities.
