A more thorough explanation:

Definition: A moot case is a legal matter in which a controversy no longer exists. It is a case that presents only an abstract question that does not arise from existing facts or rights.

Example: A person files a lawsuit against a company for a product that caused harm. However, before the case goes to trial, the company recalls the product and compensates all affected customers. The lawsuit becomes a moot case because the controversy no longer exists.

Explanation: In this example, the controversy between the person and the company no longer exists because the company has taken corrective action. Therefore, the case becomes moot, and the court cannot make a decision on the matter.

Example: A group of citizens files a lawsuit against a city council for approving a construction project that they believe will harm the environment. However, before the case goes to trial, the city council cancels the project. The lawsuit becomes a moot case because the controversy no longer exists.

Explanation: In this example, the controversy between the citizens and the city council no longer exists because the project has been canceled. Therefore, the case becomes moot, and the court cannot make a decision on the matter.
