I've assumed (or heard @ practitioner or coach trainings) that more than one individual cannot be assigned to a lead link role - but I have not been able to find/verify that assumption in the constitution.
Imagine the case of a Role that is assigned to Peter, Paul and Mary. Then the Role is expanded to a Circle. What happens to the existing role assignments?
If more than one lead link is allowed - note the caveat in 2.4.2 "as long as that won’t decrease the clarity of who should enact the Accountabilities and authorities of the Role in common situations" then are both considered lead link or should one be assigned a 'focus' of lead link?
Asking for a friend.
