Depends upon what area you are in. If in "The West" then general meeting attendance has degraded markedly from 90% to about 70%. Many "listen in" with phantom illnesses that wouldn't stop them from e.g. going to work, shopping or eating out.
Also depends upon the body of elders world view as a group.
Usual rules apply - if the brother wishes to qualify as an elder he is unlikely to be allowed. If he already is an elder then one or two on the body will have a quiet word with him.
But if he is otherwise liked and used and especially if there is a need in the hall for elders then he will probably be allowed to continue with much tut-tutting and eye rolling from those in the cong that have their antenna up for inconsistency and hypocrisy.
