Key legal question
Whether the BGFA allows a lawyer to be entered in more than one cantonal bar register.
Extracted holding
The BGFA presupposes a single bar-register entry in the canton of the lawyer's main business address; multiple simultaneous cantonal entries are excluded.
Extracted reasoning
Text, legislative history, and purpose show that registration is tied to one canton only. A multiple-entry system would complicate and fragment disciplinary supervision and undermine free movement.
