No idea about the legal viability of it, but if you presented us with that we wouldn't go to the party. Any party we've been to has never had anyone totally unknown at it. People that are not known to the hosts are known to other party goers. There is more likelihood of getting bad behaviour than press leaks from totally unknown guests, and your form suggests that you are possibly not always inviting known quantities.
If you want decent, reliable, legal advice, find and pay for a lawyer.
Personally I'd be somewhat wary of going to a party where I was required to sign a non-disclosure agreement, and I can see that I'm not alone.
Its disgraceful that consenting adults enjoying harmless,mutual pleasure in private should be ratted on by these hypocrites but I don't see how this idea would stop that.
I see where your going with this but I wholeheartedly agree with the notion of getting to know your guests first.
At the end of the day I know I would rather trust a friend than a stranger... at least on SH strangers are gonna eventually become good even lifetime friends...
I haven't began to scratch the surface with some fab peeps I've conversed with in the forums & chatrooms... but I know I would feel far 'safer' knowing I was with them at a venue than anyone else who had to sign a 'gagging' clause!
What's more I never read the sunday red tops but don't you know its sometimes a source that leaks the story... & the legal minefield you would be faced with will be insurmountable.
For example if I sign any 'legal gagging' document & my pert bottom is splashed over the sunday sewage... I reckon I could have a good case to sue you for not protecting MY privacy!
If your gonna dance with the Devil...
Have you actually thought that by taking them to court you are kind of defeating the object of the contract (which is unlikely to hold a great deal of water as it is a gagging order of sorts and they just don't work in the real world- only courts have the real power to impose them). So you take the blabber mouth to court and then have to confirm (in front of the media) all of your details, the details of your parties, the details of who was there......
I fail to see what you would acheive??
BTW - as it is not a common law issue and a damages issue - you woud need to prove actual damages to you.
You have a very tough case on your hands there,
IF and its a big IF the persons who signed were who they said they were in the first place you may well be able to take action based on the agreement but what do you do to check people are who they say they are in the first place?? Proof etc as no press man would give his/her real details to start with!! Forget it and have fun... no one should be doing anything there ashamed of anyway and I'm blindin sure as hell I wouldn't answer questions to anyone I was a bit suspect with never mind have my pics taken for them lol
Just a thought..
