    Robert M. FOX, Jr., Petitioner, v. Sam JOHNSON, Chairman Polk County Commissioners; Grady Judd, Sheriff of Polk County; Polk County Sheriff’s Office; and Polk County Commissioners, Respondents.
    No. 2D13-5031.
    District Court of Appeal of Florida, Second District.
    July 2, 2014.
    
      Robert M. Fox, Jr., pro se.
    Janet A. McDonald, Assistant County Attorney, Polk County Attorney’s Office, Bartow, for Respondent Polk County.
    Mario J. Cabrera, Polk County Sheriffs Office, Winter Haven, for Respondent Polk County Sheriffs Office.
   ALTENBERND, Judge.

Robert M. Fox, Jr., seeks a writ of certiorari with respect to the circuit court’s order denying his amended petition for writ of mandamus. In his amended petition, Mr. Fox, in essence, claimed that he was entitled to “statutory gain time” for time he was in county jail in Polk County Circuit Criminal Case Numbers CF93-4441A1-XX and CF94-3348A1-XX prior to being sentenced to prison on the revocation of his probation in those cases. He sought a writ of mandamus to require the Polk County Sheriffs Office and the Polk County Board of Commissioners to award him gain time pursuant to section 951.21(1), Florida Statutes (1993), which concerns gain time for good conduct for county prisoners. At the time Mr. Fox sought this relief in these cases, he was no longer a county prisoner. He had already been sentenced to prison and committed to the custody of the Florida Department of Corrections to serve his prison sentences, and neither the Sheriffs Office nor the County Commissioners had the indisputable legal duty, or even the power, to award him section 951.21(1) gain time against his DOC sentences. See, e.g., Haines v. Broward Cnty. Bd. of Comm’rs, 695 So.2d 818, 819 (Fla. 4th DCA 1997) (affirming denial of petition for writ of mandamus that had been sought to require sheriff and county commissioners to award defendant gain time pursuant to section 951.21, Florida Statutes (1995), for time the defendant was in temporary custody of the sheriff, court explained “[ajfter a state prison sentence has been imposed, a defendant’s entitlement to any gain time, even for a temporary stay in county jail, is a decision that rests with the Department of Corrections”).

Accordingly, we deny Mr. Fox’s petition for writ of certiorari.

Petition denied.

      . Mr. Fox was adjudicated guilty of two counts each of lewd act upon a child under sixteen and contributing to the delinquency of a minor and one count of attempted sexual battery on a child under twelve in Polk County Circuit Criminal Case Numbers CF93-4441A1-XX and CF94-3348A1-XX. A portion of his sentences for those offenses included probation, which was subsequently revoked. Mr. Fox has initiated numerous proceedings with this court, most of which appear to have been filed after the revocation proceedings were commenced and all of which have merited no relief. See Fox v. State, No. 2D14-2572, 2014 WL 3557640 (Fla. 2d DCA June 10, 2014) (denying petition for writ of mandamus by order reported at 2014 WL 3557640); Fox v.

State, 92 So.3d 829 (Fla. 2d DCA 2012) (affirming per curiam with citations in case number 2D 11-6121 summary rule 3.800 appeal); Fox v. State, 90 So.3d 285 (Fla. 2d DCA May 30, 2012) (affirming per curiam with citations in case number 2D12-2025 summary rule 3.800 appeal); Fox v. State, 30 So.3d 500 (Fla. 2d DCA 2010) (affirming per curiam with citations in case number 2D09-5319 summary rule 3.800 appeal). In conjunction with the foregoing proceedings, Mr. Fox has made a multitude of filings, including motions for rehearing that were entirely frivolous.
      Mr. Fox has also initiated at least two proceedings with the First District Court of Appeal that merited no relief. See Fox v. Fla. Dep’t of Corr., 136 So.3d 1217 (Fla. 1st DCA 2014) (denying petition for writ of certiorari on the merits in case number ID 13-4006); Fox v. Fla. Dep’t of Corr., 133 So.3d 932 (Fla. 1st DCA 2013) (denying petition for writ of certiorari on the merits in case number ID 13-2603).
      Finally, at present Mr. Fox has one undecided proceeding pending with this court. See Fox v. State, No. 2D 13-5256 (Fla. 2d DCA filed Oct. 23, 2013) (appealing order imposing sanctions and prohibiting Mr. Fox from filing any further pleadings without the assistance of counsel).
      We intend to direct Mr. Fox, by separate order, to show cause why this court should not direct the clerk of the court to reject all appeals and original proceedings filed in this court related to circuit court case numbers CF93-4441A1-XX and CF94-3348A1-XX, unless the filing is submitted by a member in good standing of The Florida Bar pursuant to State v. Spencer, 751 So.2d 47 (Fla.1999).
