Initiative 1501, a proposal dealing with “protection of seniors and vulnerable individuals from finance crimes and victimization,” will appear on the fall statewide ballot in Washington.

Secretary of State Kim Wyman certified I-1501 on Monday. The state Elections Division finished a random sample of the 341,376 signatures submitted by the initiative backers in early July. The signature review determined that the measure easily exceeded the bare minimum of 246,372 valid signatures needed to qualify for the ballot.

Wyman said a random sample of more than 10,000 signatures for I-1501 showed most were valid. Rejection rate due to duplicates or invalid signatures was 12.78 percent, lower than the average error rate of 18 percent.

I-1501 is the third Initiative to the People that has qualified for Washington’s statewide ballot. In late July, I-1433 (boosting the state minimum wage to $13.50 an hour over four years, up from the current $9.47 per hour) and I-1491 (dealing with gun restrictions for those covered under temporary “extreme risk” protection orders), also were certified.

A signature checking crew at the Elections Division is now reviewing a sample of signatures for I-1464, which covers campaign finance reform, disclosure and enforcement, and creation of a public campaign financing program. An Elections Division official said the I-1464 check could be completed Tuesday or Wednesday.

Two citizen-generated measures, Initiatives to the Legislature 732 (carbon taxes) and 735 (opposing Citizen United court decision), already have qualified for the fall ballot.
