When is it ethical for a city to use the process of condemnation to assemble land for a project? (condemnation being taking of land in exchange for payment as authorized by a court of law).
The usual test is: "does it meet a public purpose".
Where does public purpose end? Here are some examples:
A sewer project
A highway interchange
A public park
An industrial park
A downtown development project which will be private
An industrial site for a large employer providing desperately needed new jobs
Where do you draw the line?
