Some of the ways are already known: your company can be denied lucrative government contracts if you deny. Or you might learn you can't export your products due to export restrictions. Other ways are known to exist, but details are not available yet - go read about National Security Letters, or kangaroo "secret courts".

Not that I don't agree, but how do you know the secret courts are kangaroo?

[kook_throwaway]

The fact that it's secret.

Also that you aren't even allowed to show up to defend yourself. [1]

Also that they denied 11 out of 34,000 requests over a 35 year period.

Also that the judges are appointed by one person and don't even need congressional approval.

How could it possibly not be a kangaroo court?

Courts that aren’t adversarial are just interpreting law. Secrecy makes it worse by eliminating accountability by the petitioner and judge.

For a non-secret example, look at the Social Security “fair hearings”, where an administrative law judge basically listens to a petition and makes a decision. The standards vary significantly by locale.
