Unspecified power is a legal term that refers to the authority of a court or other governmental body to make decisions without any limitations or restrictions. It is often used in cases where the exact limits of a court's power are not clearly defined, allowing the court to make decisions based on the facts of the case. NTH is an abbreviation for the Latin phrase nunc pro tunc, which means 'now for then' and is used to refer to a court order that is made retroactively.'
