There is plenty of case law that refers to hunting, fishing, and driving as privileges. It don't take long to search the district courts, state supreme courts and SCOTUS cases. I could do it, but I feel I am wasting my time arguing with people who think it is a constitutional right or rights are being violated with these game checks. Argument that it don't hold water is false in itself as
@VikingsGuy points out. There are however, some states where the legislatures and/or activists have succeedded in making it a constitutional right in those state though. Tale a look at Texas.
In Wyoming, they do not have to issue you a license if they believe you have been doing anything illegal. True they have to be able to have articulatable reasonable suspicion, not just because. Wyoming can cancel seasons on a dime for a variety of reasons. Lion and bear are perfect examples. You are supposed to check in every day and call a number to verify the season is still open before going out hunting that day. Wyoming can revoke your license to hunt for a variety of reasons (usually you done something and pending court).
