RULE 26.1 Corporate Disclosure Statement

(a) Who must File. Any nongovernmental corporate party to a proceeding in a court of appeals must file a statement identifying all its parent corporations and listing any publicly held company that owns 10% or more of the party's stock.

(b) Time for Filing. A party must file the statement with the principal brief or upon filing a motion, response, petition, or answer in the court of appeals, whichever occurs first, unless a local rule requires earlier filing. Even if the statement has already been filed, the party's principal brief must include the statement before the table of contents.

(c) Number of Copies. If the statement is filed before the principal brief, the party must file an original and 3 copies unless the court requires a different number by local rule or by order in a particular case.
