It means there was a warrant issued for your arrest and apparently an attorney filed a motion asking the Court to withdraw/quash the warrant for your arrest.
It looks as though a warrant was issued for your arrest for violating your probation. Someone has file a motion to essentially deactivate the warrant. Call the clerk of court to find out who filed it and why.
A motion to quash is a tool used to ask a Judge to recall a warrant for arrest that has been issued. Until that motion is granted you should be aware that there is an active warrant for arrest. Good Luck
Although AVVO answers provide a starting point, nothing replaces the opinion of a qualified DUI defense attorney knowledgable about the Judges and prosecutors near you. You should consult a local lawyer for legal advice. Www.orlandocriminalteam.com Www.orlandoduiteam.com Www.orlandoduilawfirm.com Www.flduilawfirm.com Www.orlandodivorceteam.com
