The L.A. County District Attorney has officially rejected the drug case stemming from T.I.’s arrest last month apparently due to legal problems with the case.

As you recall, Tip and his wife, Tameka “Tiny” Cottle were busted in L.A. back on September 1 for possession of a controlled substance.

The D.A.’s Office has decided not to move forward with charges because, in essence, he’s already been sentenced to prison since the arrest was a violation of his federal probation. VIEW DOCUMENT (.pdf file)

Law enforcement sources tell TMZ that the decision was made because there were significant legal issues over the probable cause which led to T.I.’s arrest.

Cops claimed they smelled marijuana but no pot was ever booked into evidence.  And, we’re told …T.I. was pulled out of his $250,000 Maybach immediately after he made the illegal U-turn and prior to any registration check.

Looks like things are working out for the kaaaang…. no word yet on Tiny’s charges.
