Former Nebraska state senator John Kuehn files lawsuit to block medical marijuana petitions' certification due to invalid signatures and procedural violations.

A former Nebraska state senator, John Kuehn, has filed a lawsuit to block the certification of two medical marijuana petitions intended for the November ballot. Kuehn argues that many signatures are invalid, claiming violations of state law and procedural rules. He contends that if these signatures are removed, the petitions may not meet the required threshold for certification. The lawsuit also challenges the petitions' adherence to the state's single-subject rule.
