Katy Perry and her Dark Horse co-creators slam the jury’s decision that the 2013 hit single copied off of Christian rap song, Joyful Noise.

The jury of the case ruled that Perry’s track infringed the copyright of rapper Marcus gray a.k.a Flame. Now, Perry and others are calling the ruling “an injustice.”

In a statement to Variety, Perry’s defense attorney Christine Lapera said:

“The writers of ‘Dark Horse’ view the verdicts as a travesty of justice. There is no infringement. There was no access of substantial similarity. The only thing in common is unprotectable expression — evenly spaced ‘C’ and ‘B’ notes — repeated. People including musicologists from all over are expressing their dismay over this.”

The statement represented Perry, Dr. Luke (Lukasz Gottwald), Cirkut (Henry Walter), and Max Martin (Karl Sandberg); rapper Juicy J (Jordan Houston); and lyricist Sarah Hudson.

“We will continue to fight at all appropriate levels to rectify the injustice,” Lapera concludes in the statement. Perry’s team is expected to appeal the verdict. “They’re trying to own basic building blocks of music, the alphabet of music that should be available to everyone,” Lepera said Thursday.

Gray and two other co-authors first sued Perry and her team five years ago. After a seven-day trial was held the jury consisting of six women and three men ruled in favor of Gray. The nine-member federal jury released their decision on July 29. Perry’s camp is set to pay USD 2.78 million in damages with her label Capitol Record footing the majority of the compensation.
