By christ you're thick.
Think of it this way:
If you're renting a property and have a contract with the real estate agent, does the owner of the property have the right to enter the dwelling at any time they wish?
No, they have to ask for your (the tenants) permission.
If say your lease agreement runs through out 2010, and then in Feb 2010, the owner of the property wishes to hold a party at your house in October. You are being asked to vacate the premises for a week.
Does the owner have any legal right to do this?
No.
The owner of the property legally requires your permission to do so. And you can legally expect compensation IF you agree to this.
If the government want a property for something they do not own they compulsorily acquire it. Simple. If the government own something they do not have to compulsorily acquire it.
Nowhere did I say anything about who has what ****ing contract with who or what the **** they would have to do as a result of it. Comments were being made about the government acquiring the ground compulsorily but they would not have to do it do you ****ing get it now yes they would have to break contracts but that is not what I was saying.
