The Chatham House Rule is not a legal principle. If you violate it by recording a meeting in a one-party consent state, the most likely consequence is that you wouldn’t be invited back. (Someone else posited legal consequences under contract law, but I’m not a lawyer.)
And for the record, California is not the only two-party consent state. There are twelve others.
It’s not a legal thing at all. It’s a social agreement that people opt into at an event.
Legally you can go to an event and act in bad faith without breaking the law. That’s not cool, but you’re not getting arrested for it.
If (or when) word gets out that you’re breaking the rules, or worse, secretly recording people against their wishes then you’d find yourself excluded from those groups and private events.
how is state law differing a glitch? privacy law is under developed federally considering the changes in scale distribution, storage, and capture tech. recording people without their awareness is a lie of omission that many would consider rude and manipulative.
You can be recorded in public.
In most of the US states you can be recorded in private so long as the one recording is a party to the conversation.
Why does California do this separate weird thing? It doesn't feel like my rights should go away when I cross into your state. It feels like a glitch.
