If a character is not listed in the All Character listing, you cannot arrest, prosecute, sentence, etc. that character. In the case of characters who have retired, especially high-level characters who voluntarily retire, they are beyond the reach of the state whether a confirmed traitor in Switzerland or an alleged traitor in Hispanola. Having said that, their names can still be dragged through the mud and they can be branded traitors after the fact (as, I believe, was the case with CLdS).
The Minister of State is the King's right-hand man, and as such, he can issue statements in the King's name. As long as these statements do not contradict established game mechanics, they will carry the full force and support of the King. When there is a gray area in the rules (and there are a few :), preference will be shown to the position/view of the current MoS.
Lastly, only the CoPS has any right to issue arrests. Even in duelling cases, they are brought before the CoPS and he can either turn them over to the MoS (i.e., arrest them as a freebie - doesn't count against 5 limit) or else let them go with just a verbal reprimand or somesuch. These do not count toward a conviction in the first six months - the CoPS must come up with something on his own (and get MoS buy in since he is the one who actually convicts :).
