The article aims to present the intense exchange of vacancies in the permanent committees of the
Chamber of Deputies. It was adopted a longitudinal approach to the party composition of all permanent
committees installed in the Chamber of Deputies, in the period between 1991 and 2022. This is an
exploratory, documentary analysis. Centrality measures that are closely associated with the possibility
of embarrassment or influence of a given actor/party were elucidated. It was mobilized a set of network
analysis techniques and models to demonstrate the occurrence of intense movement of vacancies in
the composition of permanent committees between the different parties represented in the Chamber of
Deputies, regardless of the presidential administration. It is possible to risk saying, based on the data
presented and notes, that this is not a specific phenomenon of a given moment, of a government or
of a given coalition formation. The exchange of seats involves all parties and/or party blocs and all
permanent commissions.
