Bankers Life Casualty Company v…
“ If we applied the reasoning advanced by the petitioner, then every interlocutory order which is wrong might be reviewed under the All Writs Act. The office of a writ of mandamus would be enlarged to actually control the decision of the trial court rather than used in its traditional function of confining a court to its prescribed jurisdiction. In strictly circumscribing piecemeal appeal, [4] Congress must have realized that in the course of judicial decision some interlocutory orders might be erroneous. ”
