Is rule nisi legal?

Legal nisi rule

A “rule nisi” is a name given to a court ruling, order, decree or judgment to indicate that it that adjudication is to stand as valid valid and operative unless the person affected by that adjudication appears before the court to show cause against it. It is different from the usual order to show cause. The usual one states that something will be done in the future unless the party that does not want that to be done appears in court to show cause why it should not be done. In a rule nisi, the “something” is already taken but the party has an opportunity to argue against it.
