Sony executives were sued in 2012 by publishers at Mayimba Music, who claimed Loca was a copy of Ramon Arias Vasquez's song Loca con su Tiguere.

In 2014, U.S. District Judge Alvin K. Hellerstein ruled Sony/ATV Latin and Sony/ATV Discos executives were liable for copyright infringement, but in August (15), he reversed his decision after Sony lawyers offered proof that the cassette Vasquez had allegedly used to record his version of the song was not from 1998, as the defence had claimed. It was in fact from 2011, when Vasquez registered for copyright.

On Tuesday (03Nov15), publishers at Mayimba Music filed a motion to vacate the judgment, claiming it was made based on fabricated evidence. Executives at the company also revealed their lawyer was dealing with a medical condition that affected his job performance at the time of the last ruling.

They also asked U.S. District Judge Alvin Hellerstein to deny Sony bosses $2.2 million (GBP1.4 million) in legal fees, because it would force them to file for bankruptcy, according to Billboard.com.

Loca, written by Dominican singer El Cata, appeared on Shakira's 2010 album Sale el Sol.
