New York — Music mogul Sean “Diddy” Combs has formally begun the process to challenge his recent conviction and prison sentence, with his legal team filing a notice of appeal in the Federal District Court of New York on Monday.

The appeal comes less than three months after the Grammy-winning artist was sentenced to 50 months in federal prison on prostitution-related charges following an eight-week trial. The jury, however, cleared him of the more severe racketeering and sex trafficking accusations that once threatened to bring a much longer prison term.

Attorney Alexandra Shapiro, representing Combs, submitted the appeal notice on behalf of the 54-year-old entrepreneur. The filing did not specify the legal grounds for the challenge, but Combs’ defense team has previously argued that the statute used transportation for the purposes of prostitution was misapplied and should not have been used as a basis for conviction.

During the July trial, prosecutors presented testimony from 34 witnesses, describing what they claimed were organized efforts connected to prostitution. The court rejected the government’s bid for an 11-year minimum sentence, instead handing down a little over four years.

Combs, who has already served one year in custody at the Metropolitan Detention Center in Brooklyn, will receive credit for time served. At sentencing, he broke down in court, saying, “I’ve been humbled and broken to my core.”

Before his sentencing, the music executive penned a letter to the presiding judge, expressing remorse for his actions. “In my life, I have made many mistakes, but I am no longer running from them,” Combs wrote. “I am so sorry for the hurt that I caused, but I understand that the mere words ‘I’m sorry’ will never be good enough as these words alone cannot erase the pain from the past.”

When the jury reached a split verdict earlier this year, acquitting him on racketeering conspiracy and sex trafficking charges, Combs turned to his family and said, “I’m coming home, baby! I’m coming home!”

Despite that partial legal victory, Combs remains in federal custody while his lawyers prepare to take the case to the U.S. Court of Appeals, a move that could determine the next chapter in one of the entertainment industry’s most closely watched legal battles.

Legal experts claim that federal appeals are difficult to win, often hinging on technicalities in how the law was applied.

Still, the case has drawn massive attention from both entertainment law specialists and celebrity legal analysts, projecting the broader debate about how the justice system treats public figures facing high-profile allegations.
