Plaintiffs who cried foul regarding the May 2 fight between Floyd Mayweather, Jr. and Manny Pacquiao, and claimed they deserve their pay-per-view money back are set to argue their cases in front of a federal judge in California, the Associated Press reports.

According to the report, Judge R. Gary Klausner, who heard the arguments in cases filed against the Sony movie studio related to last year's computer hacking attack, is tasked to decide if the Pacquiao cases are granted class-action status before any trial proceeds.

As noted by AP, at least 32 cases have been filed in states that include California, Nevada, Florida, Illinois, Maryland, New Jersey, New York and Texas. Since mid-May when most of the lawsuits were filed, several more plaintiffs have followed suit.

The Filipino boxer along with Top Rank Inc. are named in all of the lawsuits, with a large number of the lawsuits also including Mayweather, his promoters, along with cable companies HBO and Showtime.

As pointed out by the report, the lawsuits argue that Pacquiao's injury wasn't revealed until after fight. Some 4.4 million viewers paid up to $100 to watch the fight on PPV.

HBO and Showtime have said they made more than $400 million from what was hyped as "The Fight of the Century."

Mayweather reportedly made nearly $300 million for his efforts, while Pacquaio made over $100 million.

According to the AP report, lawsuits filed in several states will be heard in the Central District of California where Pacquiao supposedly injured his shoulder while training for the May 2 bout.

In its decision, the U.S. Judicial Panel on Multidistrict Litigation said that determining the severity and timing of the eight-division world champion's rotator cuff injury could require "significant factual, and possibly expert, discovery."

Pacquiao is currently doing "self-rehab" on his injured shoulder, while Mayweather is set to fight Andre Berto on Sept. 12.
