A more thorough explanation:

Definition: An extraordinary writ is a legal order issued by a higher court to a lower court, government official, or other party to perform a specific action or to stop a specific action. It is called "extraordinary" because it is used in exceptional circumstances where other legal remedies are not sufficient.

Example: One example of an extraordinary writ is a writ of habeas corpus, which is used to challenge the legality of a person's detention or imprisonment. Another example is a writ of mandamus, which is used to compel a government official to perform a duty that they are legally required to do.

Explanation: The examples illustrate how extraordinary writs are used in specific situations where other legal remedies are not effective. A writ of habeas corpus is used when a person's liberty is at stake, and a writ of mandamus is used when a government official is not fulfilling their legal obligations. These writs are only used in exceptional circumstances and are considered a last resort when other legal options have been exhausted.
