Last month, the TCU federal audit court froze 2.1 billion reais ($646 million) of assets pertaining to a consortium of Odebrecht SA and OAS SA, which rendered services for the Abreu e Lima refinery in northeast Brazil.
Supreme Court Justice Marco Aurelio Mello ruled that the law cited to seize those assets applied only to public servants.
The decision applied to the Odebrecht assets frozen by the TCU decision. OAS must appeal to the Supreme Court separately.
Odebrecht declined to comment on the matter.
