Okay, so imagine you want to sell some apples to your friend. You tell them that you will sell them a basket of apples for $5. They agree and give you the money. But when they get home and open the basket, they find that there are only a few apples in there, not a whole basket like you said.
Your friend is very upset and wants their money back. So they take you to court, which is like going to the principal's office when something goes wrong at school. The court has to decide who is right - you or your friend.
This is what happened in the court case of Hill v C Parsons & Co. A man named Hill bought some seeds from a company called C Parsons & Co. The company said that the seeds would grow into a certain type of flower. But when the seeds grew, they turned out to be a different type of flower.
Hill was not happy and took the company to court. He said that they should give him his money back because they did not give him what he paid for. The court agreed with Hill and said that the company had to give him his money back.
This court case was important because it showed that companies have to be honest about what they are selling. They cannot trick people into buying something that is not what they say it is. Just like you cannot trick your friend into buying a basket of apples and then only give them a few.
