In case anyone is still tracking this topic...
Last night someone sent me a copy of a document delivered by the CEOs of ISO and IEC earlier that day to the ISO Technical Management Board (TMB). That documents summarizes the four appeals filed in relation to the adoption of DIS 29500 (OOXML), and provides a response to each claimed basis for appeal. Those appeals, you will recall, were registered by the National Bodies of South Africa, India, Venezuela and Brazil, not all of which have became publicly available.
The recommendation of the CEOs is as follows:
The processing of the ISO/IEC DIS 29500 project has been conducted in conformity with the ISO/IEC JTC 1 Directives, with decisions determined by the votes expressed by the relevant ISO and IEC national bodies under their own responsibility, and consequently, for the reasons mentioned above, the appeals should not be process [sic] further.
