That Must Have Been an Interesting Day in Chambers. Law.com reports that "5th Circuit Rules in Rappers' Battle Over Phrase 'Back That Ass Up'." From the article: "The appeals court disagreed with D.J. Jubilee's arguments and affirmed the jury's verdict. The jury, as instructed, likely believed that the hook in Juvenile's song was not the phrase 'back that ass up' but rather a sample from the Jackson 5's song, according to the opinion."
