It does now. It didn't originally. For instance, it would be unlikely that reguilation of non-point source pollution (such as sediment from run off) could have been regulated. Other examples are habitat degredation for endangered species; required canopy closure at timber harvest; in other words, many environmental regulations. There are also the historic district paint color regulations; many building codes such as prohibiting the use of PVC pipe.
For instance, it would be unlikely that reguilation of non-point source pollution (such as sediment from run off) could have been regulated.Why? Because of lack of political will, or lack of technical means?
Again:
The Court also accepted the wisdom of the legislature as sufficient for the purposes of regulation as long as they could not be proven to be arbitrary or unreasonable and a"substantial relation" to the police powers could not be disproven.
Is it the same meaning to substitute unenforceability could not be disproven.?
