Phil Nichols hit the nail on the head. Illegal acts are passed everyday by political bodies trying to appease their constituants, but unless somebody, or some organzation, has the cash, the smarts, and the time to fight illegal acts nothing will change.
I asked those questions because a "gentleman" from SD was railing against a former MN resident who moved to SD to get around their nonresident trapping regs yet still held his lifetime trapping, hunting and fishing license in MN. The SD "gentleman" in question started spewing off about the Privileges and Immunities Clause and, I think it was, the Commerce Clause of the US Constitution. So I dug out my research information from a few years back when I wrote a term paper in one of my Business Law courses at college about such abuses by State Fish and Game Departments - in particular, Michigan's DNR and Legislature. Over on lynxcat.proboards.com where this discussion took place, I printed portions of two US Supreme Court rulings, and my interpretations of them, that clearly says that while a State has the right to manage the wildlife within its borders for the benefit of its citizens, the State does not have the right to prohibit, or hinder/restrict, nonresidents from engaging in the same forms of interstate commerce that the residents of the State are allowed to engage in. Trapping and selling fur pelts, and doing adc work, are both commercial enterprises just like commercial fishing, logging, or operating any other business and thus fall under the protection of the Privileges and Immunities Clause and the Commerce Clause of the US Constitution. But according to these rulings the State does retain the right levy taxes, and as such the State can assess a nonresident a higher license fee for their license as long as the license fee isn't so high that it becomes a burden on commerce by becoming prohibitive to nonresidents. Other than that nonresidents are to be afforded the same privileges and immunitites as residents are - in other words the same rules and regulations as residents. For your reading pleasure if you want to look them up the cases I cited were USSC Cases; Baldwin v. Fish and Game Commonwealth of Montana, 436 U.S. 371 (1978) and Toomer v. Witsell, 334 U.S. 385 (1948).
Doug, not stirring the pot, just providing some food for thought and possibly some ammunition for an individual that might want to open an adc business in another state or go to another state to trap where nonresidents are prohibited or greatly restricted.
Pesky, nonresidents are operating their adc businesses within the borders of MI, and they have permits issued by the MDNR the same as some OH and IN pesticide applicators operate in MI under the authority of their pesticide applicators license issued by the MI Dept of Ag.
