PORTLAND – Maine could pay up to $200,000 for an outside, Boston-based lawyer to defend the LePage administration in an ongoing lawsuit over voter-approved Medicaid expansion.

The Department of Health and Human Services in a state form dated Monday proposed increasing the cost of a no-bid contract with Boston law firm Consovoy McCarthy Park from $100,000 to $200,000 through December.

Advocates for Medicaid expansion are suing to force Maine to follow a voter-approved law expanding Medicaid to as many as 80,000 low-income residents. Republican Gov. Paul LePage’s administration is fighting a state court order requiring Maine to seek federal funding for Medicaid expansion.

Democratic Attorney General and gubernatorial candidate Janet Mills has allowed the governor to hire lawyer Patrick Strawbridge as outside counsel. Her office refused to defend LePage’s administration against the lawsuit, and Chief Deputy Attorney General Linda Pistner said at the time that the office could take “whatever position the public interest requires in the pending litigation.”

Mill’s office and the LePage administration didn’t immediately respond to requests for comment.

Maine’s online database of governmental spending shows Maine’s risk management claims fund paid out $92,098 for legal services to the firm from January through May. The firm’s lawyer Strawbridge has represented the governor in several legal issues in the last year, including lawsuits over critics blocked from the governor’s Facebook page, the LePage’s administration’s steps to close a rural minimum-security prison and the governor’s moves to hold up public campaign funds.

Strawbridge has also represented the governor in a long-running lawsuit in which unsuccessful Democratic gubernatorial candidate and former House Speaker Mark Eves claims LePage sabotaged his private sector job offer.

LePage last year sued Mills for refusing to represent his positions in court and joining a legal effort in support of protections for young immigrants facing deportation. Maine’s attorney general is the only one in the country to be appointed by the Legislature.

Maine has paid out nearly $478,000 since 2014 to Consovoy McCarthy Park and a Portland law firm that have both represented the LePage administration, according to the state’s database last updated in late June. That includes about $216,000 from Maine’s general fund, and $262,000 from the state’s self-insurance fund.

Portland firm Roach Hewitt Ruprecht Sanchez & Bischoff had represented the state in litigation concerning the governor’s steps to remove young adults from the state’s Medicaid program and to defend a state policy withholding benefits to certain immigrants.
