The judge overseeing Detroit's bankruptcy case on Wednesday postponed deciding whether the city can redirect utility tax revenue to help fix its broken street lights, citing a potential conflict of interest among attorneys representing the city's Public Lighting Authority, Reuters reported on Wednesday. Law firm Miller Canfield represents the lighting authority, but also represents Detroit in other matters in the city's bankruptcy proceedings. Bankruptcy Judge Steven Rhodes asked attorneys from all parties involved to submit briefs by Dec. 4 to address the potential conflict of interest and whether Miller Canfield should be disqualified from representing the Public Lighting Authority. Judge Rhodes said that he will subsequently issue a written ruling. The potential conflict came to light when attorney Jonathan Green, a lawyer for Miller Canfield who represented the lighting authority in proceedings before Judge Rhodes on Wednesday morning, introduced himself in court.
