"The basis of that jurisprudence is that the jurisdiction under 3.1(7) is not a substitute for an appeal. There must be additional material before the court in the form of evidence or, possibly, argument. I would reserve the issue of whether additional argument in itself is enough to attract the jurisdiction of rule 3.1.(7), but the general thrust of Collier is that the case before the court before which rule 3.1(7) is moved must be essentially different from one of simple error that could be righted on appeal."
