The main change introduced by such Provisional Measure was the increase, from 20% to 49%, the ceiling of voting equity that foreigners could hold in a Brazilian airline company, which could be of even 100% provided that there was reciprocity in the treatment of Brazilians in the country of origin of the foreigner wishing to hold equity in a Brazilian airline.
The reciprocity requirement had been excluded by Congress, which was strongly opposed by specialists in the field. It was expected, therefore, that Vice-President Temer would only veto the lack of need for reciprocity, preserving the advances brought by the Provisional Measure.
The political backstage is commenting that the Vice-President was strongly influenced by certain Senators, who are against the increase. The Senate is currently processing the impeachment application of President Dilma Rousseff.
