Okay kiddo, let me explain prejudice in a way that's easy for you to understand.
Prejudice is when someone judges you or treats you badly just because of who you are. For example, if someone doesn't like you just because of your skin color or the way you dress, that's prejudice.
Now, in the legal world, prejudice means something else. It's when a judge or jury already has a biased or unfair opinion about someone before even hearing all the facts of a case. This is not fair because everyone should be judged based on the evidence presented in court, not on their race, religion, gender, or any other characteristic.
So let's say there's a trial for a person who's accused of stealing something. If the judge or jury already thinks that the person is guilty just because they belong to a certain group, that's prejudice. This can be a big problem because the defendant may not get a fair trial, and that's not the way the legal system is supposed to work.
So, in summary, prejudice in the legal procedure is when someone is treated unfairly because of who they are, even before all the facts are presented in court. It's not fair and it's not right, and everyone deserves to be treated equally.
