A number of years ago, I had a student go out for a solo, as he got out of the adiz around dc, he ran into clouds lower than expected, so he turned around. Unfortunately, popped the adiz on his turn before he had gotten a new squawk to return. If you are familure with the adiz, that results in an automatic suspension of your licence.
Straight from the fsdo's mouth, he could only take action against ratings held at the time of the incident, so the fsdo nicely dragged it's feet for 10 days untill the student obtained his ppl, and then took his student licence.
He was happy with the result
