PROFESSOR MANDELKER: As a beginning, I wish to give you some background on urban redevelopment in this country. As a young lawyer, over fifty years ago, I was assigned to the department in the then Federal Housing Agency that was responsible for the then brand new Urban Redevelopment Program. One of our functions was to guide the states and local attorneys whose programs were beginning to be challenged constitutionally because theydid not serve a public use. We wrestled with those issues and gave legal guidance.
