St. Peters, Mo. officials threaten homeowners with up to $180k in fines and 20 years in prison if they do not tear out garden (photos here) and replace it with grass on at least 50% of the yard. (Later, officials say just 5% grass will suffice.) An excessive fine? A violation of the substantive due process right to quiet enjoyment of one’s property? The Eighth Circuit dismisses the case on procedural grounds.
