I agree, but it's not something that is constitutionally requested if I understand it correctly, as objection testing seems only to be restricted to governance meetings.
right, that's my understanding as well.
See Constitution 3.2.5 "Testing objections": "The Facilitator MAY test the validity of a claimed Objection by asking the Objector questions"...unless it is required by a circle member: (3.2.6. "The Facilitator MUST test an Objection if requested by any Core Circle Member").
However, interesting point you brought up about integrating it into the constitution. It is not specified IMO how that objection testing works outside meetings and if it is (always) the Circle Facilitator testing (and which one in case of different circles...). Interesting point...some additional clarity might help indeed.
