This part caught my eye:
Lack of Consideration
The only purported consideration that Disney provided through the Development Agreement was its agreement to demand no more than fair market value for Disney-owned lands that the District might need for any public-facilities projects that Disney may obligate the District to undertake pursuant to the Development Agreement. But the District already had the power to take private lands for public projects and to pay only fair market value for those lands.
Without adequate consideration by both parties, the contact is unenforceable.
Any thoughts from those who have read the entire development agreement?
