Arum submitted a formal request to the Nevada Attorney General's office on Monday asking for an inquiry into the circumstances surrounding the fight. Senate Majority Leader Harry Reid, the senior senator from Nevada, also has asked for an investigation.
Jennifer Lopez, a spokeswoman for the Nevada Attorney General's office, said in an email to the AP that Arum's complaint is currently under review.
"We are treating the complaint like any other complaint our office receives," Lopez said. "We do not confirm or deny if we have an ongoing criminal investigation."
The Nevada State Athletic Commission's executive director, Keith Kizer, said this week that he has no plans to review the fight, even though he acknowledged having Pacquiao ahead.
Commission chairman Skip Avansino told the Las Vegas Review-Journal that he was content with the scoring, while Ford defended his scorecard in an interview with the newspaper.
"I thought Bradley gave Pacquiao a boxing lesson," Ford said. "I thought a lot of the rounds were close. Pacquiao missed a lot of punches and I thought he was throwing wildly."
Arum believes the decision — along with the Nevada commission's reluctance to conduct its own investigation — could provide the impetus for a federal commission to provide oversight for the sport, which has long battled the perception that it is rife with corruption.
"If the commission here in Nevada will be in intransigent, and won't cooperate, we have to have a federal commission," Arum said. "We have to examine who these are on the commission, how they got there, how they operate. Something is broke."
Stats compiled by Compubox showed Pacquiao landing 253 punches to 159 for Bradley, and having a 190-108 edge in power punches. Pacquiao landed at 38.5 percent to 27.7 percent for Bradley.
The decision ended Pacquiao's 15-fight winning streak, but also sets up a potential rematch later this year. There has been talk that it could happen in November.
Perhaps by then, Arum will have the clarity he is seeking from their first fight.
"Any other sport — football, baseball — the commissioner's office would investigate," he said. "I'm not saying hang anybody, but let's get clarity here. Let's get a complete report as to what happened. They could say, 'Hey, all three judges had a bad night.' That's possible, too. I'm not leaping to conclusions. I want to know as well as anybody else."
