I agree with nicolaou's comment above.
When I was railroaded into a sham of a meeting behind locked doors in the back room, I objected and said "I'd like to bring someone else in please"
When they denied that, I simply said "well, you won't mind me recording this then" as I started my smartphone app.
They told me I couldn't record it, and I simply replied "well, that's inappropriate for you to dictate. I will record it, and I trust that it will serve to put all of us on notice to behave in a respectful manner"
The circuit overseer in the room said "I don't give you permission to record it!"
To which I said "well, you have dragged me in here under false pretenses, and have acted like bullies...so I WILL be recording it. It's up to you whether you wish to proceed or not"
