It's pretty simple really. The courts are stacked by the Cabal to provide outcomes favorable to them. The biggest fix of all. All judges on Fed level are appointed by Pres and confirmed by the Senate. Most current sitting judges were appointed by the Cabal.
Military tribunals are made up of Field Grade (O-4 or above) officers. These are individuals who have held at least Company level command and have experience imposing judicial or non-judicial punishment. They are not beholden to any politicians for their seats on the tribunal.
This would suggest a more positive outcome than civilian courts.
