The WTS is almost mute on this point. The only info that shows up under a search for "Disfellowship" and "Resurection" is the following:
*** w77 6/1 pp. 347-348 Mourning and Funerals?For Whom? ***
It would seem that this distinction could even be observed in connection with the funeral of a disfellowshiped person. A Christian congregation would not want its good name besmirched by having it associated with any to whom 2 John 9, 10 applied, even in their death. But suppose a disfellowshiped person had been giving some evidence of genuine repentance and had been coming to the meetings and manifesting a desire to be reinstated in the congregation. Then, if the elders felt that it would not disturb the peace and harmony of the congregation nor bring reproach upon God?s people, there would be no objection to an elder?s giving a talk. How are they to know whether Jehovah has already forgiven him or not, since there is some evidence of repentance? Properly, the elders may have been waiting, wanting to make sure that his seeming repentance was sincere. Obviously, each case being different, it would need to be judged on its own merits. Of course, if a funeral talk is given, care would need to be taken not to dwell on personal matters nor to make any positive statements about whether he will be resurrected. But a fine Scriptural presentation and witness could certainly be given.
