Mister Amaya,
To answer your questions in short:-
1. No. The Representative does not have executive authority to enact things on her own, but given she also holds office as a member of the Crookback Council, proof would have to be forthcoming that this was a direct violation of her legal duty. You may direct misuse of government powers to the Regalian Assembly.
2. Yes, they may. The Crookback Council has the legal right to create any law within their borough to be enforced, meaning the Council's actions in the eyes of the law are in fact legal within their own borough.
3. Yes, if it is within the Crookback Borough only. See point 3.
4. Yes. There are a variety of reasons a person may be arrested without breaking the law. For example, questioning and investigation. This is true even in Regalian Law.
5. If the banishment decree was specifically against Playero, no. Self explanatory.
6. Not officially but given the tribunal would have no judicially binding judgment and has a direct connection to Government, they can but only if the information is brought to the Noble Assembly for final verdict.
7. No.
8. No.
The Judiciary will not be ruling on matters of the Crookback Council so your request for a trial is denied as is your request for injunctive relief. You may refer any queries relating to the Crookback Council and their authority to the Noble Assembly who you incorrectly stated as having no jurisdiction. The Crookback Council exists by virtue of Government implementation, ergo, majority vote in the Assembly will hold the Crookback Representative and Council accountable.
As a final remark, I would suggest more proactive measures to clear your reputations than continuing to cause issues for people. Being a nuisance, causing a ruckus and continuously wasting people's time is not virtuous.
