Speaking of which,
@Maugan Ra, I have a lore request: What sorts of judicial punishments are there in Rokugan? If someone's been taken by the magistrates, accused of smuggling, how long does he generally have before something dire happens, and what would that dire thing be?
In the vast majority of cases, a criminal investigation in Rokugan is settled by a confession, whether it be written or verbal. To try and close a case without one is difficult, but permissible in the case of evident guilt or the death of the criminal in question.
Notably, a confession given under torture is entirely permissible, and magistrates will often resort to it in order to elicit a confession from a sufficiently stubborn suspect.
Smuggling is a serious crime - by avoiding taxes, one is essentially stealing from one's lord, and such conduct directly violates the celestial order. For a peasant to do so is even worse. There is considerable regional variation in what constitutes an appropriate punishment, but 'Public execution via boiling oil and the seizure of all assets' would not be unusual.
Thus, you have until they start torturing Strong Birch (the uncle), plus however long it takes him to crack, in order to fix things. How you do that depends on your exact objectives, as well as the specific details of the case.

You could actually clear the peasant's name relatively easily. You are a guest at Winter Court with ties to an Imperial functionary and who just saved the local magistrates from a potentially embarrassing situation. If you cited some reasonable evidence (you have a peasant retainer of your own who helps track everything that goes through the Pass) behind why you believed that the
heimin wasn't smuggling and made a reasonably convincing case - which is to say, passed a Sincerity roll - you could probably get him released relatively easily. The magistrates are unlikely to be too concerned about the fate of a simple peasant.
The downside of such an approach is that everyone involved would
know that you'd intervened to save the peasant for reasons of your own, and you are a Scorpion. There would probably be an increased degree of scrutiny on both him and you for a while as a result, as people try to figure out what you're
really up to. This could potentially cause the peasant more trouble later down the line, after you've left.
...probably sucks less than 'boiled to death while your family watches', though.
