Why was Oscar Pistorius released on bail?
Chief Magistrate Desmond Nair said defense attorneys had met the threshold for proving the "exceptional circumstances" required by South African law for the release of a suspect charged with premeditated murder.
He said prosecutors had failed to prove that Pistorius was a flight risk or had a propensity toward violence.
What are the conditions of his release?
Announcing the original terms of Pistorius' release, Nair set bail at 1 million rand -- or about $112,000.
He banned Pistorius from drinking alcohol or returning to the property where the shooting happened. Nair also said Pistorius must surrender his passport and not approach any airports.
However, in March, Judge Bert Bam said the athlete's attorney could hold his passport instead of the court and that Pistorius was entitled to use it to travel outside South Africa.
Pistorius should report his itinerary a week before leaving and hand his travel documents back over to his lawyer within 24 hours of returning to South Africa, he said.
Bam also said Nair had not included the prohibition on Pistorius returning to his home or a requirement that he report to a police station twice a week in the written court order he signed.
This meant those provisions, which the magistrate only mentioned verbally in court, should be ignored, he said.
Prosecutor Gerrie Nel told the court he planned to serve Pistorius with an indictment on June 4.
Why was the issue of premeditation such a focus of the bail hearing?
There is only one crime of murder in South Africa -- and premeditation is not a requirement. It is simply defined as the intentional unlawful killing of another human being.
However, premeditation plays a role for bail and sentencing. For the purposes of bail, if the charge is premeditated, it falls into a category with the most serious crimes, for which the defense must show exceptional circumstances to obtain bail.
South African law makes it difficult for defendants accused of premeditated murder to get out on bail. The law requires evidence of "exceptional circumstances" to justify release, and the onus is on the defense to prove this. Grant said it was more difficult to deny bail to someone on the lesser charge.
Nair upgraded the charge against Pistorius to premeditated murder, saying he could not rule out the possibility that the track star planned Steenkamp's death. But the magistrate said he would consider downgrading the charge later.
Where will Pistorius' trial take place?
Despite being South Africa's lower courts, regional magistrates' courts can hear all criminal cases barring treason, so it is possible that Pistorius could be tried in such a court.
However, Grant said the high court, which hears cases deemed too serious for magistrates' courts, could be in a better position to hear Pistorius' case.
"Given the interest in this and given the possible sentencing that might follow -- if it is established that this is premeditated -- the high court would be in a better position to hear it and to sentence," he said.
A high court trial could take place before a single judge or before a judge and two lay people, who are usually legal experts such as advocates, academics or retired magistrates, who are known as "assessors." These assessors are restricted though to answering questions of fact.
Their role is to advise the judge, who is not obliged to follow their guidance on questions of law, but they may overrule a single judge on questions of fact.
Why will Pistorius face a judge rather than a jury trial?
South Africa abolished jury trials in 1969, while the country was under apartheid, due to fears of racial prejudice by white jurors.
Grant said the change showed that despite it being the "very dark old days," some members of South Africa's judiciary and legislature had been somewhat enlightened.
When will Pistorius' trial begin?
Some high-profile or important cases in South Africa have been fast-tracked and pushed through within a month, but that is "highly, highly exceptional." What is more likely, said Grant, is that the trial would get under way within about six months.
Examples include the fast-tracking of trials during the 2010 World Cup.
How long is it expected to last?
If the trial follows an ordinary course, Grant said, he would expect it to last four to six months -- but that would depend on how aggressively the defense challenged the prosecution case.
"They could dispute everything, in which case there could be 'trials within trials,' " he said.
But he said the defense would have to balance that "against not appearing to challenge things for the sake of it" and alienating the court.
Grant's understanding is that there are few witnesses that could be called -- neighbors among them -- but that if character was to be raised as an issue, "it could cause an explosion of witnesses."
"It could just drag on forever."
What about appeals?
If the trial is heard in a magistrates' court and Pistorius is convicted, he could potentially appeal from the magistrates' court, to the high court, to the supreme court and even eventually to South Africa's constitutional court.
If the initial court did not give him leave to appeal, he could petition South Africa's chief justice for permission.
The right to appeal depends on whether, based on the facts of the case, the initial judge or magistrate believes a different court could possibly reach a different verdict.
South Africa's highest court, the constitutional court, used to be only for cases regarding constitutional matters, but a recent act of parliament broadened its remit.
