The lawsuit claims the tragedy was the result of “a motivation for profit at the expense of concertgoers’ health and safety” and the “encouragement of violence,” according to Billboard.
“Defendants failed to properly plan and conduct the concert in a safe manner,” wrote Mr Souza’s attorney, Steve Kherkher, of the firm Kherkher Garcia LLP.
“Instead, they consciously ignored the extreme risks of harm to concertgoers, and, in some cases actively encouraged and fomented dangerous behaviors.”
The deaths and injuries happened during chaotic scenes at the first night of the festival, when some in the 50,000 person crowd appeared to surge towards the stage as Scott performed, crushing some of the victims.
Mr Souza’s lawyers state in court papers that the two-day event should have been cancelled earlier on Friday when “concertgoers breached a security gate around the park, stampeded into the premises, and trampled over one another.”
The lawsuit alleges negligence and gross negligence and is seeking at least $1m in damages.
Lawyer Kevin Haynes, who is also involved in the case, told Billboard: “This was unnecessary. This kind of thing is not supposed to happen. There were things that were supposed to be done that were not done.”
In a second lawsuit, Scott and hip-hop star Drake are both named in $1m damages claim filed on behalf of another injured victim, according to Fox News.
Texas attorney Thomas Henry filed a lawsuit on Sunday against Scott, whose real name is Jacques Bermon Webster, as well as Drake, whose real name is Aubrey Drake Graham.
The suit was filed on behalf of concertgoer Kristian Paredes, 23, from Austin, Texas, according to Mail Online.
Paredes reportedly filed the complaint seeking more than $1 million in damages after both rappers allegedly “incited the crowd” and left him injured.
