Convicted crack cocaine dealer Antwain Robinson, 36, was sentenced Wednesday by Chief U.S. District Judge Brian A. Jackson to 30 years in prison.

A jury convicted Jackson in February of possessing more than 50 grams of crack cocaine with intent to distribute the illegal drug.

Assistant U.S. Attorney Robert W. Piedrahita stated in court filings that Robinson also had a felony conviction in 1996 in state District Court in Baton Rouge for possession with intent to distribute cocaine.

Piedrahita also noted Robinson was convicted in January 2001 in state District Court in Lincoln Parish for possession with intent to distribute crack cocaine. Robinson was sentenced to seven years in prison for the 1996 conviction in Baton Rouge, court records show.

By October 2000, Robinson was charged in the crack cocaine case in Lincoln Parish. He pleaded guilty and was sentenced in March 2001 to 15 years in prison, court records show.

Nine years later, he was indicted in Baton Rouge federal court on the crack cocaine charge that resulted in the 30-year sentence Wednesday.

Piedrahita noted in court records that the third drug conviction could carry a sentence of life imprisonment.

But Rebecca L. Hudsmith, federal public defender, and Mark Upton, assistant federal public defender, argued that the Fair Sentencing Act of 2010 permits a lower sentence in crack cocaine cases involving less than 10 ounces of the drug.

Jackson agreed with the defense attorneys and imposed the 30-year term.

Robinson announced he will ask the 5th U.S. Circuit Court of Appeals to reverse his conviction.

Robinson has been in federal custody since August 2010. If his conviction stands, he will not be eligible to seek early release before October 2035.
