One: Was it judicial determination that was the ADR that is used in the supreme court trial division. I was like WTFFFF.
Definitely. You got it right!
Two: With that question asking about the composition of jury, I spoke about how it may not be a true cross section because the jury can have ineligible, disqualified and excused for good reason, and I said that the accused (should have wrote defendant) can use preemptory challenges and just cause challenges.
You didn't need to say it won't be a true cross section as you're delving into the territory of a jury evaluation. It would've been correct to say the questionnaire is one factor that will influence the composition of the jury (and then identify the concepts that you did--eligible, ineligible, excused, and disqualified). Empanelment and challenges is distinct from the questionnaire, however. You can only get awarded for a single factor, not both.
Will I lose marks for terrible structuring and getting things wrong or are they just looking to give me marks? I'm not sure if they can subtract marks.
Proper structuring is crucial for the 10 marker. They can penalise you if your ideas in the discussion are confusing or illogical. You shouldn't have delved so much into the referendum process; it is not relevant to a discussion on parliament's ability to make law.
Re: The 5 marker on High Court's ability to change the ConstitutionI think you were meant to refer to the fact that it's the sole interpreter of the C/W Constitution (the power given to it by sections 75 and 76) and could therefore change the meaning of the words of the Constitution. Maybe chuck in an example here.
You were then meant to go on and say how it /can't/ change the C/W Constitution -- i.e. it cannot change the written words (this is only through a referendum), and it must wait for an appropriate case to arise before it can even interpret the Constitution. It can't go and change the meaning of terms in it out of its own volition. I also made another point about this, but it escapes me right now.
Re: A+ cutoffHonestly, it's pretty hard to guess. I think there were a couple of tricky higher-order thinking questions (namely the 2nd last question and the ones that required extra thinking to do with the High Court and the referendum one), but it'll be roughly the same as the one last year or a tiny bit lower.
Try not to worry too much about it, as there's nothing you can do to change what you've put down--be happy with the effort you put in and remember there are things you answered which some people would've been clueless on or not even been able to get up to.
