Brazil has experienced a process of constitutional denaturation, a movement of disfiguration of the basis of democratic constitutionalism. The impeachment of President Dilma Rousseff opened place to several neoliberal reforms. The Congress approved unconstitutional constitutional amendments such as the imposition of the Public Expenditure Ceiling and the Pension Reform, in addition to the Labor Reform, which directly impacts the protection of the social labor law established by art. 7 of the Constitution, in a process of deconstitutionalization. The hypothesis is that these constitutional changes, both formal and informal, generate the denaturation of the Constitution. The choice for the expression “denaturation” occurs because there is a breakdown of democratic assumptions, supposedly consolidated since 1988, a movement parallel to the changes in relation to social rights. Therefore, the Constitution, from 2016 onwards, takes on an increasingly less social and less democratic support.
