When someone is accused of doing something very bad that breaks the rules of society, they have to go to a special place called court to decide if they did it and what should happen next. If the court decides that the person did something really, really bad and deserves a really, really serious punishment, they may give them the punishment of death.
However, sometimes people can be punished with death even if they didn't really do anything that bad or even if they were innocent. This is called judicial murder. It's very, very wrong to punish someone for something they didn't do or for something that isn't really that bad.
That's why it's very important that courts are very careful and fair when they decide what should happen to people who are accused of doing bad things. It's also important to have people who can double-check to make sure that the courts are doing their job correctly. This helps to make sure that everyone gets treated fairly and justly.
