AUGUSTA — The LePage administration went back to court Monday in its bid to hold up the voter-approved Medicaid expansion until funding is in place, filing a second appeal of a lower court ruling requiring the state to move forward with the implementation. LePage’s legal team had appealed the lower court ruling to the Maine Supreme Judicial Court and on Monday it went back before the state’s highest court to ask it to delay the deadline it was given to file a formal expansion plan while the court considers its appeal of the underlying issue.
