On a 4-3 vote, the ruling went against our interests and those of the general public, in favor of the narrower interests of casino owners and operators. Below is a link to the Opinion, which also briefly explains the case for those who are not familiar with it. The three dissenting Justices appeared to understand the importance of this issue to society in general; the majority ignored it.
Being able to keep people out of public meetings and conventions because they possibly used their brains in the casino or any other whim of those in charge opens the doors to all types of new abuses by casino owners and managers, including such things as banning delegates with whom they disagree from political meetings and conventions (think R-J owner Sheldon Adelson). The implications of this decision are far worse for a wide array of more important issues than skilled casino patrons.
We need to get our well-thought-out comments into the mainstream media.
