Moody decided to overturn the conviction after he learned Terri Wright, foreman for Banton's 2011 trial, allegedly conducted independent research while serving on the case and shared it with the other jurors, Zap2it.com reported.
Wright has since been charged with criminal contempt and could face a fine and up to six years behind bars if convicted, officials said.
Banton is serving a 10-year prison sentence for cocaine trafficking and conspiracy. His lawyer is considering filing for appeal on those charges, the celebrity news website said.
