Task: songer_origin

What follows is an opinion from a United States Court of Appeals. Your task is to identify the type of court which made the original decision. Code cases removed from a state court as originating in federal district court. For "State court", include habeas corpus petitions after conviction in state court and petitions from courts of territories other than the U.S. District Courts. For "Special DC court", include courts other than the US District Court for DC. For "Other", include courts such as the Tax Court and a court martial.

PER CURIAM.
In this case a debtor who admittedly committed an act of bankruptcy, namely, made a general assignment while owing three creditors more than $500, was petitioned into bankruptcy by said creditors. It pleads that the petition should be dismissed because the assignment was a more profitable way to dispose of the matter, and that the creditors signed the petition only because of poor advice given them by their attorneys, induced by the latters’ dislike of counsel for the as-signee and by a desire to obtain a fee. The district court ordered this special defense stricken.
It may be assumed that in any case counsel hope for a fee. Were we to countenance this novel attempt to avoid bankruptcy proceedings that were admittedly appropriate and warranted, it would mean that in every instance the wisdom of the petitioning creditors and the reasons their counsel advised them to file would be the subject of inquiry. The case presented is a far cry from fraud.
Judgment will be entered affirming the order of the District Court.
