Abstract: The study aimed to analyze the actions of the Professional Councils in relation to 966 professional-ethical complaints addressed to the Regional Council of Medicine of Minas Gerais between 2012 and 2017. The number of cases, gender, articles violated of the Code of Medical Ethics and decisions made in the lawsuits were considered. An expressive result was observed in terms of acquittal (535 cases) by the Regional Council of Medicine of Minas Gerais. There was a divergence when the same cases were evaluated by the Federal Council of Medicine, which upheld the acquittal in only 29% of the cases. Due to the methodology applied, it was not possible to go beyond speculation on the subject, being necessary a better analysis of the scientific community on this issue.
