AceShowbiz - Pop sensation Miley Cyrus is wrestling with a lawsuit that accuses her of copying significant parts of Bruno Mars' "When I Was Your Man" in her chart-topping single "Flowers." The crux of her legal defense? The lawsuit, they argue, has a "fatal flaw" that mandates its dismissal.

The lawsuit, filed by Tempo Music Investments in September, claims that "Flowers" steals "melodic, harmonic, and lyrical elements" from Mars' 2013 hit. Tempo had obtained the rights to the song from Philip Lawrence, one of its four co-writers.

However, Cyrus and her legal team, led by attorney Peter Anderson, argue that Tempo's rights are not enough to support their lawsuit. They highlight the requirement under the Copyright Act that only "exclusive" copyright owners can file infringement lawsuits. Since Tempo acquired rights from just one of the song's co-authors, they argue, it does not have the standing to sue.

In their motion, Cyrus' team insisted, "Plaintiff unambiguously [says] that it obtained its claimed rights in the 'When I Was Your Man' copyright from only one of that musical composition's four co-authors. That is a fatal and incurable defect in plaintiff's claim."

Anderson emphasized, "In the case of joint works, the co-authors are joint owners of the exclusive copyright rights, each owning a non-exclusive interest in the undivided whole."

Tempo Music, however, countered this argument, with their lead counsel Alex Weingarten calling it a "bogus technical argument" and stating, "We're not an assignee; we're the owner of the copyright. The law is clear that we have the right to enforce our interest."

Beyond the issue of standing, Cyrus' team also contends that the two songs exhibit "striking differences in melody, chords, other musical elements, and words." Anderson argues that the supposedly copied elements are "random, scattered, unprotected ideas and musical building blocks."

This legal clash adds another layer to the narrative surrounding "Flowers," a song that has resonated with many fans and internet sleuths who believe it serves as a response to her ex-husband Liam Hemsworth, a purported fan of "When I Was Your Man."

The latest filings from Cyrus seek a dismissal without any chance to amend, asserting that other co-authors of "When I Was Your Man," including Bruno Mars, are not parties to the lawsuit. As Cyrus' team prepares for the next round of legal battles, Tempo Music remains steadfast, confident in their standing to bring forth the case.
