The movement claim that Nebbia v. New York's broad liberty definition is the Supreme Court's majority holding, not a dissent, is unsupported

The majority opinion upheld New York's milk-price regulation as a valid economic regulation under the police power. Reading the dissent as the holding inverts the case's actual significance.
