A more thorough explanation:

The Factor's Act is a law that provides protection to buyers of goods from a factor or agent. This law creates a presumption that the agent was acting on behalf of the owner and with the owner's approval.

John owns a clothing store and hires a factor to sell his products. The factor sells a shirt to Sarah, who later finds out that the shirt is defective. Sarah can use the Factor's Act to hold John responsible for the defective shirt, even though she bought it from the factor. This is because the law presumes that the factor was acting on John's behalf and with his approval.

Another example is when a farmer hires a broker to sell his crops. The broker sells the crops to a buyer, who later discovers that the crops are not of good quality. The buyer can use the Factor's Act to hold the farmer responsible for the poor quality of the crops, even though he bought them from the broker.

These examples illustrate how the Factor's Act protects buyers from being held responsible for the actions of the agent or factor. It ensures that the owner of the goods is ultimately responsible for any defects or issues with the products sold by their agents.
