PER CURIAM:
Ronald Eugene Rewis, a Florida State Prison inmate, initiated this petition for habeas corpus, seeking release from incarceration on the theory that he had been improperly deprived of gain time. After appropriate proceedings, the court below issued its order on February 2, 1973, 354 F.Supp. 334, directing Rewis’ immediate release. Unknown to the court and (we trust) to all other participants in the proceeding, Rewis had been set free on February 1, 1973, under an early release program.
For reasons unnecessary to relate, this appeal followed. Rewis’ petition sought only release, nothing more. This he already had when the order appealed was entered. The order was, therefore, moot ab initio. It is vacated and remanded, with instructions to dismiss the cause as moot.
Vacated and remanded, with instructions.
