So, imagine you have two friends - Chung Fook and White. They had a little argument because White borrowed Chung Fook's toy without asking and didn't return it. Chung Fook got upset and wanted his toy back, but White didn't want to give it back.
To solve the problem, they went to a grown-up called a judge. The judge listened to their argument and decided that White should give the toy back to Chung Fook because it belonged to him and White didn't have the right to take it without asking.
This is what we call a legal case - when people go to a judge to settle their argument. Chung Fook v. White is just the fancy name for the legal case they had. The judge's decision is called a verdict and it's like the grown-up's way of telling them who's right and who's wrong.
