At a time of even greater need, more than a dozen law firms along with corporate legal departments and other organizations are participating in an annual charity effort called Justice Served to support the Food Bank for New York City.

The campaign, now in its sixth year, launched in early February, and the program’s organizers are aiming to raise $200,000, said Lary Stromfeld, a Cadwalader, Wickersham & Taft partner and founder of the Justice Served campaign. That would translate to a million meals, about double from last year, when the Justice Served campaign raised funds for over 500,000 meals.
