COLUMBUS, Ohio -- Ohioans won't be voting on a measure to cap kidney dialysis costs this November after the Ohio Supreme Court determined individuals collecting signatures for the issue didn't fill out the necessary forms.

The Ohio Renal Association, which opposed the measure, challenged the petitions turned in by the Kidney Dialysis Patient Protection Amendment Committee. The amendment is backed by the SEIU, which hired a California company to collect signatures from Ohio voters to qualify the measure for the ballot.

The Ohio Renal Association claimed that individuals managing paid signature gatherers did not fill out and submit a required disclosure form before they supervised signature collection. The association claimed 145 part-petitions had been filled out before the managers submitted the proper forms.

The Ohio Supreme Court agreed and invalidated the entire petition on Monday.

"That rule applies with particular force in this election case, in which 'strict compliance' with the law is required unless the statutory provision at issue expressly states that substantial compliance is acceptable," the seven justices wrote in a unanimous opinion.

Secretary of State Jon Husted's office defended the petition, saying the Ohio Renal Association didn't provide evidence showing the managers were paid before they supervised signature collection. It's possible, attorneys for Husted said in a court brief, that the managers initially collected signatures as unpaid volunteers.

O'Connor wrote that the committee's own evidence showed the signature gathering effort was organized and managed by for-profit companies. Backers paid California-based AAP Holding Company LLC $3.6 million to circulate petitions, according to campaign finance reports.

The deadline to submit signatures for the November ballot was July 4. Amendment supporters submitted signatures of registered Ohio voters then but were about 9,500 signatures short of the required 305,591. It turned in a second batch of signatures 10 days later.

None of those signatures will count going forward if the group decides to try again to put the measure before voters, according to a secretary of state's office spokesman.

The proposed constitutional amendment would have capped dialysis costs at 115 percent of the cost of direct patient care, required annual inspections of dialysis clinics and penalize companies that overcharge patients.
