Gustavo Miguez de Mello graduated in Law from the Universidade do Estado do Rio de Janeiro in 1963.
In the 5th year of his course, Miguez won a contest among law, economics and accounting students from all over Brazil, judged by the Brazilian Association of Financial Law and had his article published in the book “Empréstimos Compulsórios” (Compulsory Loans), alongside conferences given by already renowned lawyers. His thesis prevailed and was followed by the Constituent Legislator, who gave the collection of compulsory loans the treatment of a tax.
In 1966 he wrote the introduction to “A Guide To Income Tax Law of Brazil”, published by Interamerican Tax Research, NY.
In 1968 he published in the Cahier de Droit Fiscal International – Studies on International Fiscal Law, a study on territorial competence regarding inheritance and property taxes, representing Brazil in that publication.

His work at the Federal Supreme Court resulted in the Binding Precedent No. 32, which states that ICMS tax is not levied on the disposal of salvage loss by insurers, and at the Superior Court of Justice in the revocation of Precedent No. 152 on the matter contrary to taxpayers.
