It's not that clear. The legislature cannot simply violate the law, and M97 does direct the revenues. You might have to make it a court case to get action, but at least M97 gives you grounds. It's also true that the legislature can amend M97, but that's a good thing. It will need to be amended as conditions change and the inevitable (in almost all law) unforeseen consequences appear. It would have been better for M97 to have developed in a legislative process, but nothing developed in the legislature, and the need for tax reform and revenue stability and enough money to pay the bills is upon us now. State financial crises are incredibly expensive, and the damage they do lasts for a long time. I hope that M97 passes and that the legislature fine-tunes it over time. That would be an excellent outcome for Oregon.
