Oscar Pistorius’ early release was suspended by the South African Ministry of Justice on 19 August.
The ministry said the decision to release the Paralympic champion after serving 10 months of his five-year sentence was “taken prematurely” and without “a legal basis”.
The decision has now been sent back to the parole board for review.
Oscar Pistorius, 28, was convicted of manslaughter last year for shooting his girlfriend, Reeva Steenkamp, in February 2013.
The athlete says that he accepted his girlfriend as an intruder.
It is unclear whether the decision to release Oscar Pistorius early can be reinstated before August 19 if the parole board meets to reconsider its decision.
Under South African law, a double-amputated athlete has the right to be released under “correctional supervision” after serving a sixth sentence.
However, the timing of the decision is what the Ministry of Justice criticized in a statement: “One-sixth of the five-year sentence is 10 months, and at the time of the decision, Mr Pistorius had served only more than six months of his sentence.”
The Ministry of Justice clarified that it has the power to overturn decisions taken by the parole board only in cases where the convict is serving a life sentence.
Oscar Pistorius has been jailed for five years for the guilty murder of Rieva Steenkamp, a charge equivalent to manslaughter.
On August 19, Reeva Steenkamp would have turned 32 years old. Her parents held a small ceremony for her close friends and supporters in her hometown of Port Elizabeth, throwing roses into the sea in her memory.
Justice Minister Michael Masuta’s intervention follows a petition by South Africa’s Progressive Women’s Movement, which described the early release of Oscar Pistorius as “scandalous” and an “insult” to victims of violence.
Reeva Stenkamp’s parents said the time Oscar Pistorius had served was “not enough to take a life.”
This week, prosecutors in South Africa filed documents calling for the athlete’s sentence to be reviewed and turned into murder, which has a minimum sentence of 15 years. His defense team now has a month to respond.
After his release from prison, Oscar Pistorius will spend the rest of his term under house arrest.
