Refusal to allow amendments / additional pleas

This court does not think that the refusal of an inferior court to receive an additional plea, or to amend one already filed, can ever be assigned as error. This depends so much on the discretion of the court below, which must be regulated more by the particular circumstances of every case, than by any precise and known rule of law, and of which the superior court can never become fully possessed, that there would be more danger of injury in revising matters of this kind, than what might result now and then from an arbitrary or improper exercise of this discretion.
