Extradition is on the Frequently Rejected list, as it would put any infiltrator at risk of execution every time they got captured by anyone.
The main feature request here—a judge paying the ransom for one of his realm's prisoners in another realm, with the imprisoning judge's consent—sounds like a good idea.
It's why I think these 2 ideas could go alongside each other. Keep the original system (so infils can buy their freedom after like 3 days or so?) but also allow this negotation for the judges to have the Judge pay for earlier release etc where both judges must agree. Again, we must avoid having the judge pay the 'normal ransom' price otherwise infils will walk around with 3 gold and then the judge can buy them out every time cheaply. So the 2 systems should be separate to avoid abuse.
