Why do foreign laws apply in one of my duchies?

[ngtm]

Hello everyone!

I've recently encountered a bit of a weird situation and I can't figure out how it came to this and how I can resolve it. Hope someone can clear that up for me. I did search the forums for a bit, but couldn't find a matching thread - if I've missed it, I apologize.

So, the thing is, playing as the duchy of Franconia - starting at the earliest data - I have become duke of Thuringia as well. One of the local lords of Thuringia is a tribal ruler (and a traitor!), yet I cannot revoke his title because Thuringia's crown authority laws do not permit it. My own (Franconian) laws do though.

How and why did it come to this situation? How can I resolve it, i.e. get control over Thuringia's laws?

I'll list a few facts and chronological events that may, or may not, be relevant for reconstructing what's going on:
- I started as the Duke of Franconia, being a vassal to West Francia
- The De Jure lands of Thuringia were also West Francian, with the exception of Göttingen which was part of the Kingdom of Saxony.
- A Duke of Thuringia existed, ruling over one of the De Jure counties (Thüringen, I think) as well as Plauen.
- I took Thüringen
- The Kingdom of Saxony was integrated into West Francia, making the West Francian ruler King of Saxony
- I took Plauen, which destroyed the title of Duke of Thuringia
- Having Thüringen and the third De Jure county (all except Göttingen) under my rule, I create the Duchy of Thuringia and become Duke
- I use my De Jure claim to take Göttingen
- I successfully war for independence against West Francia
- Low Crown Authority is passed in my realm
- I want to revoke the Chief of Göttingen's title because he is both a tribal ruler and a (imprisoned) traitor, but I cannot because the Crown Authority laws of Thuringia do not permit it.
- I notice the Kingdom of Saxony showing up in my Law overview and having Minimum Crown Authority. I identify this as a potential cause of the issue, Göttingen having been part of it - might just be related to the County of Plauen and its De Jure status as part of Saxony, though. Don't know exactly how this works.
- I found the Kingdom of East Francia / Germany in hopes of resolving that problem, but it does not help. As I see it, I do de facto and de jure own anything involved with Thuringia. Saxony is still in my Laws screen.

The screenshots below will show my inability to revoke the title, the duchy of Thuringia, the Kingdom of Saxony being in my laws, Saxony's de facto and de jure subjects and my own Kingdom of Germany's lands.

You might have to go to medium crown law because he's not of your religion but that shouldn't matter if he's a traitor.....

I checked everything about the province and that shouldn't matter, you've got the kingdom of Saxony on your law screen because of Plauen.

• If tribal and not independent, you probably won't be able to (may be a bug)

Looked at the wiki could be a bug.

I wasn't aware that religious revocation required medium crown authority - didn't pay attention there, it seems. But anyway, as you pointed out, for a traitor low authority should suffice.

As I read that part of the wiki, it is related to yourself being tribal, not the vassal in question, right? Otherwise it should be listed under target character/title requirements. Plus, the dependent/independent and tribal organization law bit don't make sense if those relate to the vassal, right? Well, I'm not tribal. So, if it's a bug, it's not that one, I guess.


By the way, how does that about Plauen work? If it's de facto in my realm, shouldn't my laws apply? Do Saxony's laws apply? Why? How do I change that?

The de jure laws are the ones applied, so Saxony's in your case unless the Saxony ruler is of a different religion then your German ones would apply. You cant really do much unless you have the duchy, then it de jure drift into your kingdom becoming de jure Germany.
