Key legal question
Whether a faxed appeal brief without an original handwritten signature is valid and can be cured by later submission of the original.
Extracted holding
The fax transmission was legally ineffective because it lacked the required handwritten signature; the later original would have been late, and the defect was not curable.
Extracted reasoning
Consistent court practice treats fax submissions as non-rechtsmittels because they do not bear an original signature. The same applies to photocopied signatures. A later postal original submitted after the deadline is untimely, and an ineffective fax filing is not subject to cure under the applicable procedural rule.
