Interim Measures in Arbitration in Brazil

The Third Chamber of the Brazilian Superior Court of Justice (Superior Tribunal de Justiça – STJ) recently ruled that once the arbitral tribunal is constituted the Judiciary Power no longer has jurisdiction/competence to determine any issue submitted to arbitration, including any related interim measure¹.

The case at hand involved an interim measure  (medida cautelar inominada) brought by the Brazilian company Participações em Complexos Bioenergéticos S.A. – PCBIOS (PCBIOS) against the Brazilian company Itarumã Participações S.A. (ITARUMÃ).  The parties (PCBIOS and ITARUMÃ) entered into a partnership agreement for the implementation of a project of fuel production from renewable energy sources, creating a joint venture company called Complexo Bionergético de Itarumã – CBIO (CBIO).
