Hi
I don't get why the answer is High Court.
I thought you could only appeal to there if something was unjust like in Dietrich v Queen
Hey,
So the answer here is definitely the High Court of Australia. I've attached the court hierarchy below - feel free to have a look at it while you read the rest of my answer. The case we've been given starts off at the District Court. From there, an appeal will continue to climb the court hierarchy before reaching the top of the ladder. No matter where a criminal case begins, the highest possible court to hear the matter will be the High Court of Australia. However, the case will need be given special permission first, before an appeal can go through.
Keep in mind that the question is asking for the
highest court, so although the Supreme Court and the Court of Criminal Appeal are
able to hear the appeal, they are not the highest point of call. Also, a case involving drugs will not necessarily be heard in the Drug Court. That court won't deal with trafficking, as it's primary concern is rehabilitation for drug users.
So for a quick overview, the
highest court that may hear an appeal will be the
High Court of Australia (it's in the name I guess). Cases won't go straight to the top of the chain, but they'll go through the next highest court, then the next, until they reach the HCA.
