This is why lawyers should be forbidden to hold legislative office.

I have asked this question in many fora and of lawyers in person: is it violation of the separation of powers or merely an actionable conflict of interest for a sworn officer of the judicial branch to also serve as a sworn officer of the legislative branch?

Any lawyer who serves in the legislative branch should leave the bar association before taking office and be required to apply for re-admittance after leaving the legislative branch. If this involves re-taking the bar association can then so be it.
