Questão jurídica principal
Whether the UBI procedure violated the constitutional right to a lawful and fair tribunal because of its composition and the president's tie-breaking vote.
Decisão extraída
The UBI's composition rules were constitutionally compatible; the eight-member panel and the president's casting vote were permissible in the concrete case.
Fundamentação extraída
The UBI is a special quasi-judicial body with nine part-time members and no substitutes; a quorum of six and a casting vote avoid deadlock without undue manipulation risk. The recusal of one member was disclosed to the parties, and the panel was still properly constituted.
