nProcedendo(Law) A writ by which a cause which has been removed on insufficient grounds from an inferior to a superior court by certiorari, or otherwise, is sent down again to the same court, to be proceeded in there.
Century Dictionary and Cyclopedia
nprocedendoIn law, a writ which formerly issued out of the English Court of Chancery in the exercise of its common-law jurisdiction, when judges of any subordinate court wrongfully delayed the parties, and would not give judgment either on the one side or on the other. It commanded the judges to proceed to give judgment, without specifying any particular judgment to be given. A writ of procedendo also lay where an action had been removed from an inferior to a superior court, and it appeared to the superior court that it was removed on insufficient grounds.
