A more thorough explanation:

A moiety act is a law in criminal justice that states that a portion of the imposed fine will go to the informant who provided information leading to the conviction of the offender. The word "moiety" means "a portion" or "a part".

For example, if a person reports a crime and the offender is convicted and fined $10,000, the informant may receive $5,000 as a reward for their assistance in solving the case. This is a way to encourage people to come forward with information and help law enforcement agencies to solve crimes.

Another example is the False Claims Act, which is a federal law that allows whistleblowers to report fraud against the government and receive a portion of the recovered funds as a reward. This law has been used to recover billions of dollars in fraudulent claims against the government.

The Moiety Act is an important tool in the fight against crime and corruption. It incentivizes people to report illegal activities and helps to ensure that justice is served.
