Did JKR ever address what punishment, if any, Cornelius Fudge suffered for basically allowing Voldemort's second rise to power 100% unmolested, by putting the full weight of the Ministry against the Order of the Phoenix and Dumbledore (and telling the Wizarding world Voldemort didn't return) instead of working to stop the rise (not to mention assisting Voldemort in his plans by using Dementors in Azkaban; surrounding himself with Death Eaters in the Ministry, villifying Harry Potter and helping Umbridge)?
This seems at best, criminal negligence, and at worst, treason.
We know he was voted out of office when Voldemort finally announced his presence at the Ministry at the end of OotP, but that seems woefully inadequate given his actions and their deadly consequences.
NOTE: I read " What happened to Cornelius Fudge after he resigned from his post of Minister for Magic?" but none of the answers there (nor the question) specifically address the punishment.
