The leaders of the unsuccessful campaign to write in Adrian M. Fenty for D.C. mayor during the 2010 general election have reached a settlement with elections officials over the improper use of old Fenty yard signs, according to a lawyer involved in the matter.

After Fenty lost his bid for a second term in the Democratic primary last September, a group of political activists formed the Save DC Now committee to urge residents to write in the former mayor instead of voting for Mayor Vincent C. Gray (D).

But the group ran afoul of District election law when it used old Fenty campaign paraphernalia instead of putting up its own resources to buy new. In January, the Office of Campaign Finance recommended that the organizers of the effort be fined $18,500.

At a meeting Monday, the Board of Elections agreed to cut the fine in half, said Wendell C. Robinson, a lawyer who represents Ellie Anderson, one of group’s founders. In a settlement expected to be made public in the coming days, elections officials have agreed that the fine will be assessed on Save DC Now instead of any one person, Robinson said.

That means the organizers, including Anderson and activist Joshua Lopez, will not be held personally liable if the fine is not paid by its Dec. 31 due date. It’s unclear whether the fine will ever be paid because the leaders of Save DC Now say the organization does not have any money in the bank.

“We are happy we reached a resolution on this and we are happy to move forward and continue the fight to make D.C. a better place,” Lopez said.
