The description submitted by supporters did not mention this at all, instead implying the proposal was a tax increase on the rich. State analysts said the $49 million tax increase from abandoning indexing would be mostly paid by those making far less than $250,000. Proponents also argued that the short description’s reference to increasing taxes by 3.46 and 4.46 percent, rather than 3.46 and 4.46 percentage points, was misleading, but that was not the basis for the Court’s decision.

The case was Molera v. Reagan, CV-18-0218-AP/EL (Az. Aug. 29, 2018).
