In order for this to become legal it would require a 2/3 majority vote of the legislature because it would have to change a law that was as a result of an initiative. Other bills simply need a majority.
This is not correct. After two years the law can be amended by a majority vote. It has been 15 years now.
That being said I don't think it will happen either. Look what happened to the Cougar Hound hunting pilot project. Hans Dunshee managed to kill it and the same fate would await this unless the House goes Republican. I can hope can't I!
And please don't blame WDFW for this. I'm no fan of them but this was passed by a vote of the people of the Great State of Washington or at least the State of Greater Seattle.
