It was unclear when the board would be able to meet again, justice department spokesman Mthunzi Mhaga said, but it was unlikely a new decision could be made by Friday’s initially planned release date.
Pistorius, the double-amputee Olympic runner, is serving a five-year sentence for manslaughter for killing girlfriend Reeva Steenkamp in 2013. He was eligible to be moved from jail to house arrest after serving one-sixth of that sentence, or 10 months, which is up on Friday.
Wednesday would also have been Steenkamp’s 32nd birthday, and her parents earlier held a beachside ceremony in their hometown of Port Elizabeth on South Africa’s south coast.
In blocking Pistorius’ release, the justice department said he was approved for home correctional supervision by parole officials in June, only eight months into his sentence. By law he should have served 10 months of his sentence before his case could be reviewed, the department said.
“It is apparent therefore that the decision to release him on 21 August 2015 was made prematurely on 5 June 2015 when the offender was not eligible to be considered at all,” the justice department said in a statement.
Spokesman Mhaga said “the decision of the parole board will have to be suspended” until the board can meet again for a fresh hearing. Justice minister Michael Masutha would now study Pistorius’ “profile” and the original parole board decision, the department said.
The earliest the board could now meet again would be Friday.
