José Moura was nominated to be considered as a candidate for IEEE President. The IEEE Board of Directors (BoD) is the body that decides who the candidates will be. They were also behind the proposed IEEE constitutional amendment that was opposed by more than 25 IEEE Societies because it was a rather naked power grab that would have moved much of the constitution to bylaws that could be amended by a small group of individuals, reducing regional representation, and reducing technical activities representation. You can think of it as an attempt by the BoD to Make IEEE Great Again. Prof. Moura spoke up against the amendment (including at an ITSOC BoG meeting) and in the end the amendment did not pass.
It is likely that the BoD’s decision to not nominate him is retaliation for his actions in defense of what he (and many others) felt are the best interests of the IEEE. While this Trump-esque approach to handling dissent may be popular in Washington, it seems quite inappropriate for an international organization such as IEEE. There is a petition at the IEEE website to put him on the ballot. It needs around 4,000 signatures and students members are also welcome to sign. You sign in with your IEEE account and then go to “Annual Election Petitions.” Note this is not a vote for him, but rather allowing him to be on the ballot. Please consider signing!
