British rock band Led Zeppelin on Monday effectively won a long-running legal battle over claims it stole the opening guitar riff from its signature 1971 song "Stairway to Heaven".
The band, one of the best-selling rock acts of all time, was handed victory after the US Supreme Court declined to take up the case, meaning that a March 2020 decision by a US appeals court in Led Zeppelin's favour will stand.
Lead singer Robert Plant and guitarist Jimmy Page had been accused in the six-year-long case of lifting the riff - one of the best-known openings in rock music - from a song called Taurus, written by the late Randy Wolfe of the US band Spirit.
Wolfe, who performed as Randy California, drowned in 1997, and the case was brought by a trustee for his estate. It has been one of the music industry's most closely watched copyright cases, potentially exposing Plant and Page to millions of dollars in damages.
Led Zeppelin was the opening act for Spirit on a US tour in 1968, but Page testified in a 2016 jury trial in Los Angeles that he had not heard Taurus until recently.
The Los Angeles jury found the riff they were accused of stealing was not intrinsically similar to the opening chords of Stairway to Heaven.
Francis Malofiy, who represented Wolfe's estate, said on Monday that Led Zeppelin "won on a technicality" and said that the lawsuit had accomplished its goal.
"Today, the world knows that: 1) Randy California wrote the introduction to 'Stairway to Heaven'; 2) Led Zeppelin are the greatest art thieves of all time; and 3) Courts are as imperfect as rock stars," Malofiy said in a statement.
Led Zeppelin has yet to comment on the conclusion of the case.
