The question of whether Washington voters will have their say on a measure designed to make it easier to prosecute police for negligent shootings might not be over after all.

One day after ruling that Initiative 940 should appear on the November ballot, the state Supreme Court requested a briefing by the end of the day Wednesday about how the justices' various opinions should be interpreted.

Supporters of the initiative said only a single justice, Barbara Madsen, voted that I-940 should go to voters while a compromise measure preferred by lawmakers, advocates and police groups should not. Supporters of I-940 said her opinion should not control the result of what amounted to a 4-4-1 decision, and late Tuesday they filed an emergency motion asking the court to reconsider.

"For reasons not explained, the Court seems to have adopted the view of that single Justice as the ruling of the Court as a whole," attorneys for De-Escalate Washington, the initiative's sponsor, wrote.

In their response Wednesday afternoon, frequent initiative sponsor Tim Eyman and Republican Sen. Mike Padden, who sued over the issue, said the court's action was appropriate because five justices believed I-940 should go to the ballot.

Secretary of State Kim Wyman also filed a response, taking no position on the outcome of the case but urging the court to hurry. Because of the reconsideration motion, her office had to halt certain election preparations, including notifying counties which initiatives would appear on their ballots.
