Balkinization:

What we did was legal, or, in our opinion, could have been legal. Since there are arguments on both sides, we will rely on our opinion. However, we won't let a court decide the question, because then we wouldn't be able to rely on our own opinion.

We won't answer hypothetical questions about what we can do legally or constitutionally. We also won't tell you what we've actually done or plan to do; hence every question you ask will about legality be in effect a hypothetical, and therefore we can refuse to answer it.
