If that's all you mention about the appeal, I conclude that you are pleased with the fact that it's the person who accepts the certificate and thus who maintains the incarceration of a person who decides on his or her own what ground of appeal will be recorded, as well as the fact that that appeal will be limited to questions of general importance. Am I right?
Do you believe that person will be treated better than a person convicted of second degree murder whose sentence might only be 10 years? That person could appeal on a question of rights and facts before a bench of three other persons to decide a question as important as a 10-year incarceration.
