The Nebraska Supreme Court has rejected the appeal of opponents of the measure who earlier lost their challenge to the initiative petition in district court.
Supporters of Medicaid expansion have gathered more than enough signatures of registered voters to qualify for ballot status in November. They submitted nearly 140,000 signatures. Secretary of State John Gale confirmed 105,000 of the signatures were valid, well above the threshold required by state law.
State Sen. Lydia Brash and former state Sen. Mark Christensen filed a lawsuit, claiming the initiative petition violated the Nebraska Constitution by containing more than one subject and by failing to disclose Nebraska Appleseed as a sponsor.
The Unicameral has repeatedly blocked Medicaid expansion under provisions of the Affordable Care Act, prompting supporters to take the issue directly to the voters. Supporters say expansion would cover an additional 90,000 residents who make up to 138% of the federal poverty level. The federal government has pledged to pay 90% of the cost of expansion under the ACA.
