schneiderman Consulting firm The Advance Group on Thursday received a $25,800 fine by Attorney General Eric Schneiderman and the New York City Campaign Finance Board joint investigation over the organization’s work during the 2013 elections in New York City.

The investigation by the AG’s office, along with the campaign finance board, found through its investigation that the Advance Group had worked for both city-based candidates as well as independent groups that had spending money to boost those candidates.

As per the terms of the settlement, none of the candidates who were clients of the group violated the law.

“New York voters deserve elections that are fair and free of coordination that distorts the democratic process,” Schneiderman said in a statement. “The law preventing coordination between candidates and advocacy campaigns is clear. Today’s agreement sends a clear message that campaign coordination is unacceptable in New York City and state politics.”

City campaign finance law limits the amount of contributions a campaign may receive from a single contributor, and those laws also apply to money spent by outside parities that are working on behalf or opposition to individual campaigns.

Spending done without the cooperation of a campaign is considered “independent” but that activity can include authorizing, requesting or suggesting the campaigns work together.

The investigation into The Advance Group’s work, launched in 2013, reviewed independent expenditures that had been done on behalf of political campaigns where both the spenders and the candidates were clients of the firm.

The firm had created a separate group or “alter ego” called Strategic Consultants, to act as the public face of an advocacy campaign on behalf of a client as a way to shield coordination questions.

The settlement agreement requires the firm to pay a $10,800 settlement to the state and a $15,000 fine to the Campaign Finance Board.

The firm has also pledged to seek regulator guidance going forward and establish a “firewall” that would separate candidate and third-party expenditures.
