The Justice Department is asking local courts across the country to be wary of how they slap poor defendants with fines and fees. In a letter ... to the chief judges and court administrators in all 50 states, Vanita Gupta, the head of the department's Civil Rights Division, and Lisa Foster, director of the Office for Access to Justice, wrote that illegal enforcement of fines and fees had been receiving increased attention. Individuals may confront escalating debt; face repeated, unnecessary incarceration for nonpayment despite posing no danger to the community; lose their jobs; and become trapped in cycles of poverty that can be nearly impossible to escape," Gupta and Foster wrote. "Furthermore, in addition to being unlawful, to the extent that these practices are geared ... toward raising revenue, they can cast doubt on the impartiality of the tribunal and erode trust between local governments and their constituents." The White House and the department convened a summit on the issue in December. The Justice Department alleged in a recent lawsuit that officers in Ferguson, Mo., were violating citizens' civil rights in part because their policing tactics were meant to generate revenue. The financial penalties - typically for minor misdemeanors, traffic infractions or violations of city code - disproportionately affect the poor, who cannot afford to pay immediately and are then hit with arrest warrants or additional penalties. Some towns [derive] 40 percent or more of their annual revenue from [these] petty fines and fees.
