What is nolle pros-comp pti in Florida?

Nolle Pros is short for Nolle Prosequi. A Latin term which essentially means that the prosecution declines to prosecute. Comp PTI would refer to the reason the case has been nolle pros'ed. I would probably say that it refers to completion of a Pre-Trial Intervention program, but it may have another meaning in that court district.

Most likely, the defendant has participated in an intervention/diversion program, has successfully completed it, and the prosecution therefore has, declined to prosecute.
