Except in the Supreme Court any new party to a case, whether he be joined or substituted, may in the discretion of the court have a continuance; and the court may allow him to plead anew or amend the pleadings so far as it deems reasonable, but in other respects the case shall proceed to final judgment or decree for or against him, in like manner as if he had been an original party to the case.
