Arizona Supreme Court knocks two school-voucher measures off the November ballot. As we noted Tuesday, two measures were awaiting the court; on Tuesday justices ruled that Proposition 212, the citizen initiative to impose sweeping regulations on the state's Empowerment Scholarship Account program, fell short of valid signatures, and separately blocked Proposition 145, the Republican-led referral that would have barred voucher regulations, as unconstitutional. Backers of Prop 212 said they were conceding defeat after the ruling.

Prop 144 election-law package stays on the ballot. In a separate ruling Tuesday, the Arizona Supreme Court held that Proposition 144, a Republican-backed constitutional referral making broad changes to how elections are run, can go before voters as a single measure, rejecting arguments that its provisions were improperly combined. Pima County voters will see the measure in November.
