If this case was in the Magistrate's court then fair enough they should have let it be, but it's in the High Court and many other courts will follow Masipa's errors as a precedence. She may have got the verdicts right, but there is no way she got the arguments right, and that can't be left without being challenged otherwise confusions will reign (as it already does) as to Dolus Eventualis and on whether intention to possess firearms is necessary when charging people with possession of illegal firearms.
I fail to see how the level of court affects the rights of citizens. A lower court has a higher probability of incorrect judgements and as such more reason to be open to appeal from the state - are people charged in lower courts not entitled to the same level of justice? The Criminal Procedure act makes specific recognition of this fact in that section 310 only applies to lower courts.
Masipa set no precedent. As a law student I would have expected you to have seen that - she created no new law or interpretation, only built on previous decisions. I thought it was only the uninformed who were complaining that now anybody could shoot their wife / girlfriend and get away with it. No major change took place with Masipa's judgement.
Decisions of dolus eventualis is always fraught with uncertainty and individual interpretation as it overlaps heavily with negligence. (As you should know as law student, the two are not mutually exclusive) Do yourself a favour and read the existing case law if you don't believe me. Try the Humpries appeal as a start! Masipa has in no way confused it more than it was, because as you state its only her argument which is difficult to follow.
In statutory law, intention is always required, unless the act clearly states that negligence is sufficient. First year criminal law! If you are referring to specific "intention to possess", that ship has sailed. This is precedent referred to by the learned judge, and set previously.
Yes the cost is high, but we have a budget for this so we should proceed. I'm not sure what your objection to appealing really is because the higher courts will give us more clarification. Unless you insist that clarification is not needed which is weird when it's already clear that many people are confused by what Masipa did hence the need for clarification. As a law student, I need clarification because one way or the other I am studying dolus eventualis and will at some have to refer to case law. I would hate to refer to Masipa's arguments for or against dolus eventualis verdicts.
Perhaps a garner at section 35(3)m of the constitution might give you an idea of what my reservations are. The state has historically not had a right to appeal a decision. This has evolved over time to allow review of specific mistakes (such as sentencing the wrong accused which has actually happened), and for purpose of reviewing pertinent questions of law. In this case there are no pertinent questions of law which require the SCA intervention, and the appeal is currently disallowed by act and precedent (interpretation of Section 322(4) and S v Seekoei). The state has from the first in the present trial acted in a vindictive manner, similar to when there is political bungling involved, perhaps at first to convince the public it was not giving preferential treatment, but later with major lashings of grandstanding. The ruling political party also did not take long to jump in bed with the prosecution of this fracas, having one of its daughter organizations prominently placed in the TV shot. Now the public façade is to continue even though it requires the NPA to acts differently from the norm, requiring law to shift and human rights to be eroded.
There is a maxim that "Fear drives people to consciously give up rights in exchange for security". (or a semblance of security) Historically once a right is willingly given up, it is never regained. If you are a successful law student you have probably mastered logical thinking, in the absence of emotion - why don't you follow this idea to its logical conclusion.
Dolus Eventualis is a simple principle, aptly mentioned in Masipa's judgement. I would hate to think that a single "wrong" judgement (yes there are of these, and no this is not one - at most a flawed argument) would throw a law student. It is exactly the wrong judgements that teach us the most. As to when intention by foresight of possibility is sufficient, even our appeal courts struggle with this. This should not be sufficient reason for the prosecution to get a second bite at the cherry.
