Final answer:
Punishment at NJP can be increased after it is imposed through a court process if new evidence or facts come to light.
Step-by-step explanation:
Yes, punishment at NJP (Non-Judicial Punishment) can be increased after it is imposed. According to the case of Apprendi v. New Jersey, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury and proved beyond a reasonable doubt, except for the fact of a prior conviction. This means that if new evidence or facts come to light after the initial punishment is imposed, the penalty can be increased through a court process.
