While I agree with you in principle, it doesn't necessarily hold true. You need to ask another court to declare a mistrial or for other kind of appeal. They can also refuse. You are effectively asking one judge to tell another that they are ignorant of common law. You also have to be able to afford this procedure, or figure out some way to represent yourself. You might think you can afford it. While inmates are legally afforded access to law libraries, it's basically a joke from my understanding. Something like no more than 1 hour a week.
