Okay kiddo, so there was a case called United States ex rel. Toth v. Quarles. This is a big fancy name for a legal case where two people were arguing about something.
The person named Toth said that Quarles did something wrong and should be punished for it. Toth thought that Quarles was doing bad things and breaking the rules.
The government got involved and helped Toth by taking Quarles to court. The court is a place where people go to solve problems and arguments.
In the end, the court decided that Quarles did something wrong and needed to be punished. This is called a verdict. The court said that Quarles had to pay a certain amount of money for what he did wrong.
So, United States ex rel. Toth v. Quarles was a case where one person thought the other person did something wrong and the court decided who was right and who was wrong.
