William R. Day,
Northwestern Laundry v. City of Des Moines…
“ It is averred that the ordinance exceeds the authority delegated to the city by the legislature; that it attempts to substitute its own definition of the crime and nuisance committed by the emission of dense smoke for that enacted by the legislature in the act under the pretended authority of which the ordinance is adopted; that it is unreasonable and tyrannical and exceeds the authority delegated for want of uniformity as to the whole city and because the exceptions specified are not natural and just. ”
