If after filing any paper in the appellate court, a party discovers that errors were made, the party may file and serve the required number of copies of “Corrections to (name of filing)”, listing the corrections. No document may be altered after filing; pages may not be otherwise inserted and no interlineations, additions or deletions may be made. No document may be substituted for another once filed. The number of copies filed is the same as the number of copies of the original document being corrected.
