The Brazilian impeachment (constitutional provisions)

As almost anyone who would read this blog surely knows, the Brazilian Chamber of Deputies voted to impeach President Dilma Rousseff on 17 April. The case now moves to the Senate, which could try and remove her if it concurs with the charges.

The impeachment process in Brazil is similar to that of the USA, but differs in very important detail. First it takes a two-thirds vote in the first chamber, unlike the US where the House of Representatives impeaches (brings formal charges) against the President by majority. In both countries, it takes two thirds of the second chamber (senate) to convict and remove.

The key provisions of the Brazilian constitution are from Article 51:

It is exclusively the competence of the Chamber of Deputies… to authorize, by two-thirds of its members, legal proceeding to be initiated against the President and the Vice-President of the Republic …

And Article 52:

It is exclusively the competence of the Federal Senate… to effect the legal proceeding and trial of the president and vice-president of the republic for crime of malversation…
[…]
Sole paragraph. in the cases provided for in items i and ii, the chief Justice of the supreme federal court shall act as president and the sentence, which may only be issued by two-thirds of the votes of the federal senate, shall be limited to the loss of of ce with disquali cation to hold any public of ce for a period of eight years, without prejudice to other applicable judicial sanctions.

Another nontrivial different from US procedure is that the president of Brazil can be suspended from office upon impeachment, even before the Senate trial has begun. The conditions for impeachment and trial are further laid out in the section of the constitution concerned with executive authority.

Article 85:

Those acts of the president of the republic which attempt on the federal Constitution and especially on the following, are crimes of malversation:
I – the existence of the Union;
ii – the free exercise of the legislative power, the Judicial power, the public Prosecution and the constitutional Powers of the units of the Federation;
III – the exercise of political, individual and social rights; IV – the internal security of the country;
V – probity in the administration;
VI – the budgetary law;
vii – compliance with the laws and with court decisions.
Sole paragraph. These crimes shall be de ned in a special law, which shall establish the rules of procedure and trial.

I have not seen the law referenced in that “sole paragraph”, so I do not know what further conditions or elaborations may be stated therein. I also have not seen the bill of impeachment itself, so I do not know if it cites on of the above causes. However, the reporting on the impeachment generally emphasizes charges over manipulation of accounts. More specifically (in Portuguese) that she did not respect the law of fiscal responsibility.

Article 86:

If charges against the president of the republic are accepted by two- thirds of the chamber of deputies, he shall be submitted to trial before the supreme federal court for common criminal offenses or before the federal senate for crimes of malversation.
Paragraph 1. The President shall be suspended from his functions:
[…]
ii – in the event of crimes of malversation, after the proceeding is instituted by the federal senate.

I welcome discussion from those following the case closely regarding the process, and evaluations of the charges themselves.
