Mahlon Pitney, Reinman v. City of Little Rock…
“ Therefore the argument that a livery stable is not a nuisance per se, which is much insisted upon by plaintiffs in error, is beside the question. Granting that it is not a nuisance per se, it is clearly within the police power of the state to regulate the business, and to that end to declare that in particular circumstances and in particular localities a livery stable shall be deemed a nuisance in fact and in law, provided this power is not exerted arbitrarily, or with unjust discrimination, so as to infringe upon rights guaranteed by the 14th Amendment. ”
