We have multiple Ministers of Justice and multiple level courts on Brazil , so an higher court can block lower court decisions, even more when that is still been processed.

There are several Ministers of Justice, but there is only one Ministry of Justice, that answers to the president and is not part of the Judicial Branch.

Anyway, this decision was from the PROCON-DF that is a part of the Judicial Branch where no Minister of Justice works on. It's also only valid at Brasília.
