The Court will rule in favor of the AG. Not because the AG is correct. But because trivial matters such as constitutions and settled law should not stand in the way of ‘progress’. This is, after all, 2023. Progress is the new King. The King is throwing out any and all references to past standards.
Thank you, Jason Mercier and Clark County Today for this excellent research and information.
Clearly, the “law” and past court rulings indicate this is an income tax, which must be “equal” for all citizens to pay. Because it targets only certain citizens incomes, it goes against established law.
We, the people, shouldn’t have to “hope” the state Supreme Court does the right thing, once again, and rules this unconstitutional. Nonetheless, I join my fellow Washington citizens in hoping and praying the court does the right thing.
