Legal Question in Criminal Law in Florida

You need an attorney to see if you can get a new trial. However, the first thing I would point out, and it is unclear from your post what happened, is that you have to have had a trial the first time. If your probation was a result of a plea, then you don't have the right to a "new" trial since there was no trial in the first place. Further, the grounds to reopen a case may not be legally sufficient so you need to hire an attorney to review your options.
