NEWS BRIEF
Colorado Politics reports that a lawsuit filed in Denver District Court seeks to remove Amendment 87, a proposed graduated income tax measure, from the November ballot. The case was filed on behalf of Arapahoe County resident Michael Andre Hancock and names Secretary of State Jena Griswold and measure proponents as defendants.
The lawsuit alleges that some paid petition circulators lacked required training certificates and challenges petition validation. It contends that rejecting 9,849 signatures would reduce the valid-signature total below the required threshold. Supporters of the measure said they intend to defend it.
What to know
The lawsuit has not determined Amendment 87’s ballot status. It alleges signature and petition-validation problems that, if accepted, could place the measure below Colorado’s required number of valid signatures.
