In its ruling, the Ninth found that "Stairway" did not violate the copyright of "Taurus", specifically overturning its "inverse ratio rule" which it had used in several previous cases. Perry's lawyers took this ruling as part of their appeal to Judge Snyder. On March 17, 2020, Judge Snyder overturned the jury award, citing numerous factors, including that the evidence given did not support the jury's award, and of the recent Ninth Circuit judgement. Snyder wrote "A relatively common 8-note combination of unprotected elements that happens to be played in a timbre common to a particular genre of music cannot be so original as to warrant copyright protection". Snyder vacated the jury's verdict and denied motions for a new trial, though stated that should the case be heard on appeal at the Ninth Circuit, that a new jury trial would be required. "Dark Horse" was first performed at the iHeartRadio Music Festival in Las Vegas on September 20, 2013. It was later performed at the iTunes Festival in London. Perry also performed the song with Juicy J at the We Can Survive event at the Hollywood Bowl on October 23. Perry also performed "Dark Horse" on "The Voice of Germany" on December 13, 2013. Perry and Juicy J performed the song at the 56th Annual Grammy Awards on January 26, 2014. The "dark and mysterious" performance featured a "haunted forest" design with animatronic horses, broomstick pole dances, and a controlled fire. The singer also performed the song at the 2014 BRIT Awards and the performance featured a neon-colored Egyptian theme, like the music video. On February 1, 2015, the song was performed by Perry during the Super Bowl XLIX halftime show, where she was on a chessboard, with her dancers as chess pieces. It is regarded as the most technical performance in her halftime set. Credits adapted from "Prism" album liner notes.      !scope="row"| France (SNEP)  !scope="col" colspan="3"| Streaming
