Buju Banton’s lawyer David Markus has filed an appeal challenging the 10 year sentenced imposed on the international reggae entertainer.

Lawyers representing Buju on Tuesday filed a formal notice of appeal in the US Court of Appeals for the Eleventh Circuit.

But it could take up to 18 months before Buju, knows if he will escape a 10-year prison sentence which was imposed after he was convicted on drug charges.

Minutes after the sentence was handed down last month, David Markus told reporters outside the court that his appeal would be based on the argument that there was insufficient evidence to convict Buju Banton on the drug count.

Buju is currently in a minimum security Federal prison serving his sentence.
