What's supposed to happen at an academic misconduct hearing at a college or university is that it's supposed to arrive at the truth. What happens in practice versus in theory can be a different consideration. You can't depend on the school to be looking out for your rights and interests. You can't necessarily depend on the school to respect its own processes and such proceedings. Unfortunately, academic misconduct hearings, even when all necessary precautions are taken, can at times be equated to a kangaroo court, which is very unfortunate for somebody who's accused of academic misconduct.
It's a tough fight going into it not having an experienced attorney-advisor in one's corner, and not having that expertise and knowledge to help guide snd to let somebody know what potential issues can arise would certainly be against an accused student's interests in that regard. You need to have somebody looking out for yourself who's solely dedicated to your cause. An experienced attorney-advisor can do so and should be involved as early as possible in the process.
