Corporation Commission spokesman Matt Skinner said those other cases remain open.
The Corporation Commission's public utility division filed an enforcement action against Icon in August, listing more than 40,900 possible violations for not adequately verifying customer eligibility under federal Lifeline rules. Only one Lifeline service is allowed for each household. The enforcement action said a review of Icon's customer lists showed numerous customers with the same post office boxes, dates of birth or mailing addresses.
Icon's attorney, George Makohin, argued last week in a hearing for dismissal that the commission didn't have jurisdiction to enforce federal Lifeline rules.
Icon received more than $25.7 million in federal Lifeline reimbursements in 2012, according to data from the Universal Service Administrative Co.
Both the state and federal Lifeline programs are funded from surcharges on telephone customer bills. The federal program offers eligible phone companies up to $34 per subscriber in reimbursements; the state program offers $1.85 per subscriber in reimbursements.
