I'm surprised; at the time it happened I mentioned it to a few hams and one in particular wanted details in order to file a lawsuit. He claimed he (or his group) had successfully won such cases in the past. Although this was about 40 years ago--who knows what's changed since then!
anyone can sue for any absurd reason, including some pompous ham guy who thinks his ham radio license is a badge and trumps' a private property owner's exclusive right to allow/disallow what item(s) may be brought onto their premises.
I encourage all hams, please don't be
that guy. It doesn't bode well for ham radio at large and only serves to make oneself' looks like a horses rear end in the eyes of the public. Not to mention, a company like Disney has attorneys on retainer/staff and when Joe Blow Ham Hero loses his case, he will get to pay Disney their legal fees.
This sounds like the mouse out-ranks the FCC, which sounds implausible at best...
I think you are seriously misinformed about the basis and purpose of what exactly an amateur radio license is.
It is permission to transmit radio signals in the amateur radio service, per the amateur radio service rules as codified in the CFR.
Nowhere that I am aware of in such CFR is it stated that one may operate wherever they want to on the private property of others without their permission.
I'll give you the Pepsi challenge. Come to my home and throw your ham ticket down and say you can operate here and give me the middle finger when I tell you to leave my property and pound sand. I'll let you guess which one of us leaves in handcuffs. Then you can educate a state court judge and toss your ham radio ticket around like a "get out of jail free" card and we'll see how that works out for you. Then you can come here and report your experience.
