In an opinion piece, law professor John Mogk says passage of Proposal 4 in November would cripple Detroit and damage the state of Michigan . If passed, the proposal would amend the state Constitution to prohibit use of eminent domain for economic development purposes. Mogk contends that Proposal 4 is not about protecting property owners so much as it is about blocking the Michigan Legislature from being able to authorize eminent domain for economic development, even in the public interest. "Without eminent domain," Mogk writes, "a single owner holding out in Detroit . . . could scuttle an economic development project of great public value. . . ." He calls for a "no" vote on the proposal.
