Eminent Domain

The dominating piece of news in Mississippi Law this week is Governor Barbour's statement that he will veto HB 803 which heavily restrict the State's ability to use eminent domain. What is so amazing about this bill is that is passed both the House (119-3) and Senate (51-0) with clear bipartisan support. Will the legislature override the veto? Is Eminent Domain for major private projects a proper use of this tool? Feel free to discuss in the comments.
