One big problem with the electoral court in Brazil is that it is the only public branch that concentrates the three powers in one entity: they legislate about elections, they execute the rules, and they judge any matters related to the election. As a result, they have chosen these arguments to shoot down any criticism or improvement suggestions to the election system.
The country deserves a non-politicized discussion on the ground of true technical and security merits of what the election system should be. Paper records with Risk-limiting audits would solve most of the problems. I agree with your [comments] above. The costs of implementing this pale in comparison to the benefits of having a more reliable voting process which is the basis of a strong democracy.
