With the greatest respect to the esteemed Northern Piper, the idea that the presumption of innocence is not exhausted until all appeals are final is too general a proposition to be sound.
If a person is convicted, then the presumption of innocence disappears. If the accused chooses not to lodge an appeal, then necessarily the presumption of innocence does not continue to exist as if in some sort of limbo.
While there is a right to (some) appeals, the convicted person does not have to show any sound basis for expecting success in the appeal prior to lodging it. The grounds must be cromulent, but they may be entirely without merit. It seems to me that the mere filing of a self-serving piece of paper whose merit is untested and which may be (and commonly is) baseless is hardly a basis for the magical restoration of some presumption that did not exist moments before the paper was filed.
There is the prospect of the presumption being restored if a conviction is overturned and a retrial ordered. Then, the fact that there was an earlier conviction is quite irrelevant on the new trial. If that is what is meant by the presumption of innocence not being exhausted until appeals are finalised then I am on board with that, but that proposition is contingent on the appeal’s being successful.
It escapes me how it can be a good idea for the presumption to be restored on the basis merely that some paper has been filed.
Consider this scenario. Husband and wife each with prior children had wills in favour of each other during the marriage, but they have now separated but not divorced. Husband has gone to the trouble of getting a new will; wife has not. Her will makes everything over to him, and his new will transmits that to his kids.
Ordinarily, the murder conviction will vitiate any prospect he has of inheriting from the wife, meaning that her share of the estate can be expected to go to her kids.
He appeals and tops himself, thereby (on the basis of the rule under discussion) depriving her kids of anything and enriching his own.
Such an outcome is bizarre.
I can understand the rule as some sort of gesture to lenience, but it must bend to justice. I don’t know of any other place where this rule exists - usually death brings criminal proceedings to an end retaining the legal status quo at the time of the death.
Thus, if an appeal has been lodged but not decided, the conviction abides. If the appeal has been successful and a retrial ordered as at the time of death, there is no conviction. All of that is a logical consequence of the onus of proof. The idea that, as a general proposition, during the appeal stage the prosecution has presumptively not discharged its burden despite a jury verdict in its favour is to take the idea of onus of proof off the rails.
As observed above, there is no presumption of success on appeals, otherwise appeals would succeed at a far greater rate than they presently do.
