Pursuing the actual meaning of the 'unfunded mandate' portion of the Oregon Constitution is a valid use of taxpayer money, in my opinion.  When you have people like Barnhart and Prozanski and Hoyle who believe that  their election means they can do anything on any subject anytime they like, a lawsuit to restrict their hubris can't hurt.   If  it also turns out that the counties must be paid to perform the additional tasks the Legislature chooses for them, so much the better for those of us local taxpayers who get stuck with the bill.
