Johannesburg - Lawyers for Oscar Pistorius will on Friday appeal the court decision allowing the State to appeal his culpable homicide conviction.
Judge Thokozile Masipa granted the State's application to appeal Pistorius's culpable homicide conviction, but dismissed its application to appeal his five-year jail sentence.
The State wants him to be convicted on the more serious charge of murder.
In September, Pistorius was convicted of culpable homicide for shooting dead his model and law-graduate girlfriend, Reeva Steenkamp.
He fired four shots through the locked door of the toilet in his Pretoria home on Valentine's Day 2013, apparently thinking she was an intruder.
He was jailed for five years.
