Questão jurídica principal
Whether procedural orders signed by the secretary 'for the president' were null and violated the right to the lawful judge
Decisão extraída
No nullity: the orders were presidential orders signed in the president's name for routine procedural matters, which did not infringe the right to a lawful judge or the organizational rules.
Fundamentação extraída
A defect renders a decision void only if it is especially serious, obvious or easily detectable, and if nullity does not endanger legal certainty. Those conditions were not met here.
