Questão jurídica principal
Whether the renewed challenge to the appellant’s admitted speed was barred by res judicata.
Decisão extraída
The appellant could not raise again the same challenge to the factual finding on speed, because the matter had already been finally decided in the earlier federal judgment.
Fundamentação extraída
Under the principle of res judicata, the Federal Tribunal is bound by its prior decision in the same case and is not a review court over its own judgments; the renewed complaint was therefore inadmissible.
