According to Article 16 of the Constitution of 1824, "each of the Chamber will have the Treatment of Augusts and Dignified Representatives of the Nation." Each legislature lasts four years and each annual session four months. The imperial opening session of the Assembly always takes place on May 3. Both the opening and closing ceremonies will happen with the presence of the Emperor in full imperial regalia in the form of the internal regiment and in the presence of all the members of both chambers. The appointment of the respective Presidents, Vice Presidents, and Secretaries of Chambers, verification of the powers of its members, oath, and its internal police, shall be carried out in the form of its Rules of Procedure. The Members of each of the chambers are inviolable for the opinions they give in the exercise of their functions and during their deputation, they can not be arrested by any authority, except by order of their respective chamber or in flagrant crime capital punishment. Senators and deputies may be appointed to the post of Minister of State, or Councilor of State, with the difference that the Senators continue to sit in the Senate, and the Deputy leaves vacant his place of the Chamber, and proceed to New election, in which he could be re-elected and accumulate both functions. They also accumulate the two functions, if they already exercised any of the mentioned positions, when they were elected. One can not be at the same time a Member of both Houses. The exercise of any Employment, with the exception of those of Counselor of State, the Minister of State, shall cease on an interim basis, while the duties of Deputy or Senator shall last.
