It’s strangely worded. It says “on the waters, banks or shores that might be used for the purpose of fishing”. It doesn’t seem as worded to have anything to do with fishing with a gun. It just bans guns anywhere on or near the waters that might be used to go fishing. If they mean to say “don’t shoot fish” they worded it so that it disarms everyone for any purpose if they are at a lake or riverbank.
It is quite ambiguous. For that reason alone, it should be tossed.
No one knows how many, if any, people have been charged under this regulation.
Because of the way Wisconsin law is written, there is a separate proceedure to challenge the validity of the regulation. This proceedure has to be use *before a person is arrested or charged under the regulation*. This is what gives standing in the Wisconsin lawsuit, even though the person has not been charged.
What about duck hunting?
