A more thorough explanation: A valid defense refers to a legally recognized justification or excuse that can be used by a defendant in a criminal or civil case to avoid liability or punishment.

Example: The defendant’s lawyer presented a valid defence, arguing that the evidence against their client was circumstantial and insufficient to prove guilt beyond a reasonable doubt.
