Federal Judge Turns Ordinance Dispute into “Soap” Opera
In 1973, the Fifth Circuit struck down a Dade County detergent labeling ordinance, finding that the ordinance, intended to reduce pollution from ingredients found in household detergents, was preempted by the Federal Hazardous Substance Labeling Act. Chief Judge John Brown concurred, in a delightful fashion that managed to work in the brand names of just about every detergent product available. Here’s a taste:
As Proctor of this dispute … the Court holds that Congress has specifically preempted regulatory action by Dade County. Clearly, the decision represents a Gamble since we risk a Cascade of criticism from an increasing Tide of ecology-minded citizens. Yet, a contrary decision would most likely have precipitated a Niagara of complaints from an industry which justifiably seeks uniformity in the laws with which it must comply. Inspired by the legendary valor of Ajax, who withstood Hector's lance, we have Boldly chosen the course of uniformity in reversing the lower Court's decision upholding Dade County's local labeling laws. And, having done so, we are Cheered by the thought that striking down the regulation by the local jurisdiction does not create a void which is detrimental to consumers ….
…
… And so we hold. This is all that need be said. It is as plain as Mr. Clean the proper Action is that the Dade County Ordinance must be superseded, as All comes out in the wash.
