B. Gizzle wants a new day in court.

Christopher “B.G.” Dorsey, a founding member of the 1990s rap supergroup the Hot Boys, has dug into the law books at a federal prison in Pennsylvania to challenge his 14-year prison sentence on firearms and witness-tampering counts stemming from a 2009 traffic stop in eastern New Orleans.

In a legal filing this week, the New Orleans-born rapper, who once espoused violence, drug-selling and a no-snitching ethic in his music, cries foul over the formula that U.S. District Judge Helen “Ginger” Berrigan relied upon when she sentenced him nearly three years ago.

Among other complaints, Dorsey, 34, claims federal probation authorities and prosecutors mistakenly tagged him with a leadership role in the crime — thereby hiking the sentencing guidelines range — based on his “strong personality and his famous name.”

Due to be freed in 2023, Dorsey — whose stage initials stand for “Baby Gangsta” or “B. Gizzle” — said in his eight-page motion that he “holds no ill feelings for the sentence he is serving, but respectfully requests that this court please review this sentence because the applicable criminal history category does substantially over-represent the seriousness of his criminal history or the likelihood that the defendant will commit (an)other crime.”

Just how much time Dorsey thinks he should be serving is unclear from his motion.

Dorsey won a measure of reprieve last summer in his push to appeal his conviction. Berrigan granted him extra time, agreeing that his attorney had failed to inform him of his appellate rights.

Dorsey admitted he owned some of the guns confiscated after a vehicle stop at Interstate 10 and Crowder Boulevard in New Orleans East on Nov. 3, 2009.

The Chevy Tahoe that Dorsey was riding in with Jerod Fedison and Demounde Pollard had been stolen from a rental car parking lot. Pollard claimed the drugs in the car were his.

Later, while Dorsey was out on bail, he conspired with Fedison to have Pollard sign an affidavit falsely claiming ownership of the weapons, Dorsey admitted in a “factual basis” underpinning his guilty plea.

As part of the investigation, federal agents found several YouTube videos in which Dorsey is seen giving shout-outs to two of New Orleans’ most notoriously violent figures: accused Central City crime kingpin Telly Hankton and Michael “MikeMike” Anderson, an alleged leader of the “Josephine Dog Pound” who entered a no-contest plea in 2012 for a 2006 Central City massacre that claimed five lives.

The videos were shot shortly after Dorsey made bond.

Raised in Uptown, Dorsey signed a deal with Cash Money Records in 1993 when he was 13. Four years later came the Hot Boys: Dorsey, Turk, Juvenile and Lil Wayne.

It’s unclear when Berrigan might rule on Dorsey’s motion.
