Inspired by this question and answers to it.
While I'm reasonably sure the answer is "No", I wonder if there is some interesting exception to the general immunity of legislative bodies. While a generic "misconduct in public office" or analogues can be, in some countries, applied to members of the legislative, I want a more specific law.
What I'm looking for is a law with following properties:
- It specifically concerns legislature's members.
- It sets specific bounds on what laws can be introduced to the legislature.
- There is a punishment for whoever introduces an illegal law and/or votes for it.
Bonus if someone was actually prosecuted for this.
Non-democratic examples and historical examples are fine.
