In a bid to challenge prosecutors' arguments that Oscar Pistorius should be convicted of murder, the Paralympic runner's lawyers have reportedly launched a legal appeal against them.
According to the BBC, Judge Thokozile Masipa ruled in December that prosecutors could appeal Pistorius' murder conviction charges.
In October, Masipa had convicted Pistorius of the lesser charge of culpable homicide and sentenced him to a five-year prison term, acquitting him of Steenkamp's murder.
The double amputee athlete is serving a five-year jail sentence for killing his girlfriend Reeva Steenkamp in February 2013.
