A more thorough explanation:

Praevaricatio is a term used in Roman law. It means when someone who is accusing another person of a crime secretly works with the defense to make sure the accused person is found not guilty. This is like cheating because the accuser is not being honest and fair.

• An accuser might not call important witnesses to the trial, so the defense can't ask them questions. This makes it harder for the jury to find the accused person guilty.
• An accuser might not talk about the most important charges against the accused person. This makes it easier for the defense to argue that the accused person is innocent.

These examples show how someone can use praevaricatio to cheat in a trial. It's important for everyone to be honest and fair in court so that the right decision can be made.
